Modern smartphones and tablets are equipped with increasingly capacious batteries. But power consumption is also growing, because under the body of the device there is a powerful processor, many different sensors and modules, and the picture is displayed on a huge display. That's why you can easily buy an external battery for your smartphone in consumer electronics stores. This accessory will allow you to extend the battery life several times. But only if you make the right choice.
The Chinese company Xiaomi produces very good accessories for smartphones. Portable batteries are also very popular. Mi Power Bank 5000 does not have the largest capacity, but even 5000 mAh is enough to fully charge any smartphone. And the process will not take much time - the USB connector available here is supplied with a current of 2.1 A. The battery itself is recharged in 3.5 hours, and its minimal size and weight (156 g) allow you to throw the accessory into your trouser pocket.
Main features:
This is the powerbank that is most often ordered from Chinese online stores. Its capacity has been increased, and therefore the input current has also been increased - so you don’t need to assume that the battery will take a very long time to charge. The Chinese introduced a lot of protective equipment here, but left the body metal. The weight of the accessory is 228 g - this is slightly more than the mass of many modern smartphones.
Main features:
HIPER SP7500 has two USB connectors, which allows you to simultaneously charge a couple of devices at once. But these should not be tablets, since the capacity of this battery cannot be called huge. A maximum current of 2.1 A can be supplied to the second connector, while the first is limited to the standard value. This external battery has a plastic case and its weight does not exceed 168 g.
Main features:

The strength of the incoming current can also be high, thanks to which the battery itself is charged in a very reasonable time. The accessory comes with a case that makes transportation a little easier.
Main features:
Almost every external phone battery suffers from one problem. You may forget to take a cable for it, which is used to charge gadgets. And only HIPER SPS10500 is designed in such a way that it is free from this drawback. The cable here pulls out from a special compartment - that is, it is always with you. At its end there is a special plug that combines micro-USB and Ligtning connectors. This allows you to use the accessory, including for charging your iPhone. The maximum current output is 2.1 A - this should help charge even a tablet in a short time.
Main features:
A relatively small external battery, included in our rating thanks to many positive reviews. Its end is home to two USB connectors and a bright LED that acts as a flashlight. The USB ports are supplied with currents of varying strengths - 1 A and 2.1 A. Unfortunately, the accessory itself charges slowly, since it does not support high input current.
Main features:
Inexpensive product, produced by order of the Russian trading network DNS. It has quite tolerable dimensions, and the weight with a high capacity was even reduced - to 385 g. The digital display shows the current charge level. The number of USB ports has been increased to four - this is the number of devices that can be charged simultaneously. The current output to these connectors is 1.0 A and 2.1 A. The accessory comes with a cable, at the end of which there are two connectors - micro-USB and Lightning.
Main features:
This battery is packaged in a kind of case containing rubber pads. All connectors are closed with plugs, and the main part of the structure can be pulled out of the case only after unscrewing the screws. All this should protect the protected external battery from problems that may arise in field conditions. With such protection, you can even say that this power bank is waterproof. It weighs 263 grams. To recharge gadgets, it uses two USB connectors with different current strengths. The device also boasts a built-in flashlight.
Main features:
It's no secret that modern mobile consumer electronics have one unpleasant feature, namely the need to constantly recharge the battery hidden in the case, due to which, in fact, the operation of the gadget is possible. The same applies to new generation phones, which, due to their technology and advanced functionality, have become excessively voracious in terms of energy consumption. No matter how long your smartphone runs on a single battery charge, it is still not enough, and provided that you use it quite often, the issue of extending battery life becomes even more relevant. In this material we will talk about portable batteries for mobile phones - about their characteristics and design features. We will also consider a number of interesting models that are relevant at the moment.
As mentioned above, the battery (that is, the battery) in modern smartphones requires constant recharging. Gadgets are becoming faster, more powerful, larger, but in terms of autonomy, almost nothing changes. The average battery life today rarely reaches 8 hours or more; under heavy load this value is reduced to 5 hours. And even if you stretch the existing capacity with all your might, it is almost impossible to achieve autonomy for at least two days. It sounds sad, but it's true, no matter what gadget manufacturers say. Naturally, the problem did not remain without a solution, and since it is not possible to significantly improve the autonomy of the gadgets themselves, you can use an additional battery. In the case of old-style phones that can be disassembled, once you have full access to the battery, you can replace the main battery. But there are fewer and fewer such phones; they have been replaced by monolithic cases similar to the iPhone. In this case, the additional battery is an external portable battery for the phone.
As obvious as it may sound, an external portable battery works the same as a regular (internal) one. The changes concern a slightly modified design in accordance with the scope of application of such a battery. Essentially, this is a series of power cells that are soldered to a power controller (similar to those found in smartphones). Then ports for recharging the battery itself and one or more ports for charging smartphones, tablets, laptops and the like are built into this design. Despite the simplified design compared to a smartphone, the rechargeable battery works on the same principles as in a phone, therefore the battery remains the most dangerous object in any gadget. Like any other device, an external battery has a number of characteristics that you should rely on when choosing a portable battery for your phone. How to choose the right model based on its technical equipment and what is really worth paying attention to?
The main parameter that you need to pay attention to when choosing a device. It is this indicator that determines how much additional “life” time your smartphone will receive, which means that in fact this figure indicates the efficiency of the battery as a whole. This value is directly related to the battery capacity of your smartphone. Just like the capacity of other compact batteries (smartphone, tablet or smartwatch), the battery capacity of an external battery is measured in ampere-hours, namely milliamp-hours. When choosing the optimal capacity value, first of all you need to find out the battery capacity of your smartphone (smartphones or tablet), and then find an external battery with a value of at least one and a half to two times more, so that you have the opportunity to recharge your phone (other gadget) at least once. Let's say your phone has a 2500 milliamp-hour battery. If you want to get at least one additional recharge cycle, then you should look for an external battery with a capacity of 4000-5000 milliamp-hours. It would seem that this is overkill, but in fact, the actual battery capacity always differs from that declared by the manufacturer (especially true for solutions from China). The device also loses charge even when inactive. The best option when purchasing would be a battery with a capacity of 6,000 milliamp-hours for smartphones and 12,000 milliamp-hours for tablets.
Everything is simple here: in order to share electricity with a phone or tablet, a portable battery needs a certain current strength. Typically, a smartphone needs one ampere (1A) to fully charge. With tablets and their giant batteries, a lot of power is needed, at least two amps (2A). Some portable batteries are equipped with several ports from one to three amps. This option is suitable for those who plan to charge several devices of different types at once. You can find out the exact information about how much current your gadget needs by looking at the label on the charger.
Another serious point that careless buyers often overlook is the method of recharging the portable battery itself. The fact is that some models have a specific socket connection and are generally powered only from a computer or laptop, which has a detrimental effect on the speed and efficiency of charging. Such devices are outdated and are now almost never produced, but you can still come across them. It is better to make sure that the gadget you are purchasing is equipped with a standard micro-USB port and can be charged from the mains.
When choosing a device design, you should pay attention to two important details:
Even knowing certain specifications and features of external batteries, the question of choice remains open, since a variety of companies are involved in the creation of such devices. Some make batteries exclusively for specific smartphones, while others make universal options. In some solutions, the emphasis is on external performance, in others on the technical aspect and reliability.
If you imagine an average solution that will definitely suit everyone, then it should have the following characteristics:
This knowledge is already quite enough to start an independent search for a suitable battery, but it’s still worth adding specifics. Next, we will look at various portable batteries for phones. The rating of the most interesting solutions on the market, notable for their colorful exterior, unusual design or extremely low price, is presented below.
Cost: 990 rubles.
Capacity: 10400 milliamp-hours.
A popular gadget from the Chinese company Xiaomi, which is famous for its dumping prices on fairly high-quality and well-designed devices. Xiaomi Mi Power Bank is no exception. This is a very compact and stylish gadget with a capacious battery inside. The finish is made of anodized aluminum in the style of a MacBook. High-quality, proven power cells from LG and Samsung are installed inside. As for the capacity, its actual value is 6250 milliamp hours. Xiaomi is honest with the buyer and explains this by saying that half of the capacity is wasted. This is a good portable battery for the Samsung Galaxy S6 phone as that is what the tests were done on and it can charge the battery twice. At the same time, the Mi Power Bank hardware is fully optimized to work with other modern smartphones. In general, we have an excellent portable battery for a phone, user reviews confirm this fact. Owners of the device praise its premium design, low cost and good ergonomics. There are also critical reviews, but they mainly concern defective samples and fakes.
Cost: 2,490 rubles.
Capacity: 2600 milliamp-hours.
An extravagant and intricate battery robot that attracts with its unusual style and compact size. There is nothing remarkable about its design or capabilities. It will hardly be able to fully charge a modern smartphone, and its body is made of cheap plastic. If you are ready to sacrifice everything for a stylish toy that will look cool in your hands and easily fit even in a shirt pocket (the height of the gadget is only 6 centimeters), then you should pay attention to the brainchild of OZAKI, but at the same time prepare 2,490 rubles (by the way, for this money can buy two Xiaomi Mi Power Banks).
Cost: 9,790 rubles.
Capacity: 2365 milliamp-hours.
This gadget is made in the form factor of a case and has a very narrow focus - it is suitable only for three phone models: iPhone 6, iPhone 6s, iPhone 7. This battery has a number of interesting features. Firstly, it is made of expensive silicone, durable and resistant to damage. Secondly, it has a rather unusual design, namely a bulge in the central part of the case (where the battery is located). Thirdly, with this case you can simultaneously charge your smartphone and use the same cable. There are also disadvantages, which include the impressive cost and the ability to charge the iPhone only once. It turns out that we have before us an incredibly expensive gadget, with low capacity and a very contradictory design, but at the same time the only one that is tightly coupled with the iPhone (even at the software level) and thus gives the very emotions of integrity and thoughtfulness for which the Apple corporation is famous.
Cost: 1,890 rubles.
Capacity: 10,000 milliamp-hours.
This is perhaps the most inexpensive portable solar phone battery available. Yes, that’s right, the device can be charged using solar energy; for this purpose, a special panel is installed on its body that converts the sun’s rays into electricity. The gadget boasts two USB ports that supply current with different strengths (you can charge your phone or tablet). On a sunny day, SOLAR 10 will become an indispensable assistant, and if it rains, it can be charged from a regular electrical outlet or computer. The power type is selected manually by the user using a special key on the case.
Cost: 3,989 rubles.
Another one that attracts attention with its bright appearance, but does not impress with other characteristics. The body is made of hard, matte plastic and small glass inserts. The lower part of the case is painted in a pleasant orange tint; the upper part has two displays: one of them displays a charge indicator, the other shows the same, but in the form of a pulsating neon heart. The gadget turned out to be heavy, not very functional, but at the same time surprisingly cute. Moreover, recently this beauty has dropped significantly in price. Prior to this, the high cost scared many users away from purchasing this miracle.
Cost: 14,900 rub.
Capacity: 9000 milliamp-hours.
The most advanced portable battery on the list. A true Swiss Army knife in this area of electronics. By purchasing Powermonkey Extreme, you get not only a classic battery, but also two solar ones. The kit includes a full set of adapters for different smartphones and tablets, and there are also modifications for connecting cameras and DVD players. There is a hard case for transportation and a compact strap (to hook onto a belt, for example). The battery itself is made of durable materials, as the device is designed for use in extreme conditions. Overall this is a good portable phone battery that can handle extreme conditions. Owners of the device, travelers and fishermen appreciated the gadget, singing its praises on various forums. Users complained only about the high cost.
Don't know how to choose an external battery for phone? Everything is extremely simple, but requires basic attention. How to make a wise choice will be discussed below.
Why is an external charger so popular today, since the power of standard lithium energy sources used in the same mobile phones is growing every year? We should not forget the fact that all models, without exception (or with rare “Chinese” exceptions), are positioned as smartphones.
As sales dynamics show, push-button phones if they are in the hands of users, they are rather used as backup, so as not to be “promptly” damaged during operation by the expensive iPhone.
Or, previously popular “push-button” devices are used as a status solution, but despite this, their popularity has practically disappeared.
The same smartphones that are used today differ significantly from their predecessors (compare at least the models of 2009 and 2016); in terms of their performance, modern developments are head and shoulders above their “grandfathers” in all respects.
This is the whole problem, with the increase in functionality, the performance of the phone itself, the diagonal of the sensor, on most of them the charge of a standard battery lasts for a maximum of 1-2 days of normal use.
And you must admit that if you use your mobile phone intensively, the likelihood of the battery draining at the most inopportune time is very high.
All that remains is to protect yourself by purchasing an additional power source for your mobile phone, which you can carry with you on the road without fear of stopping due to the low battery charge of your only means of communication with the outside world.
All reviews of phones with long-lasting batteries
A universal external battery that can be useful virtually anywhere.
For example, the following situations can be noted:
So, what is an external battery, or as the device is commonly called in progressive Europe, a Power Bank? According to information from the developers of such a unique device, this is a kind of set of batteries (ordinary batteries), placed in a special case, with outputs for USB.
Interestingly, this connector is universal, since you can easily purchase a set of adapters, and this way you can charge any modern mobile device.
You should be careful with older models and brands of phones, since it is not always possible to find the optimal connector for them.
The device is enclosed in a housing (plastic for cheaper models, aluminum for more expensive ones), characterized by increased strength and resistance to shocks and deformations.
Do not forget that real batteries are used for mobile devices (for example, for the same Samsung smartphones), which, if not properly supervised by the owner, can explode.
Depending on the selected model of external charger, indicators such as quality and class of batteries used may differ.
Fundamental differences are also noted in the style and concept itself, taking into account that each developer tries to “stand out” among competitors and offer the market only an original technical device.
Recently, in the market segment, impressive elements have appeared in comparison with conventional ones, which allow you to simultaneously charge several devices connected to them.
However, no matter how menacing the unit may look, its purpose remains the same - charging for smartphones and other mobile devices.
Next, it is proposed to review the most “relevant” aspects of choosing a unit in order to simply understand what is the best approach to purchasing and how this will affect the future performance of the device.
The analysis is proposed to be carried out on specific performance indicators that can be characterized as very important for the user.
The very first thing you should know about an external battery when purchasing it is the capacity indicator. What should be expected in this situation, the best unit is the one that has the maximum capacity, and this is often related to the number of batteries installed in it. The capacity indicator is set in milliamp-hours (abbreviated mAh).
Also, the number of batteries significantly affects the final weight, even the dimensions of the device itself. The larger the capacity, the more energy such a battery can deliver to your mobile device.
But not everything is so simple, I would like to pay attention to one important point.
One clear example can be given with batteries created at an official factory and at a local Chinese production.
True, this applies more to computer equipment, but official models have original factory-powered batteries. Logically, if you take a battery with increased power, it must certainly be heavier.
In fact, if you choose a cheap Chinese battery made in China (supposedly with increased power!), its weight is half that of the original one, and it holds a charge about 2-3 times less.
Therefore, you should not trust colorful stickers; it is best to check such batteries, at least by weight, or by performance indicators based on the condition of the phone.
As the technical documentation shows (and as you can verify from your own experience), external batteries are equipped with Li-on elements (as an alternative to Li-pol), which are currently positioned as the most proven energy sources relevant for recharging a mobile device. The first type is usually understood as lithium-ion elements, the second - lithium-polymer.
Among their advantages, the following can be highlighted in a nutshell:
By the way, it is worth noting that the record capacity for such devices today is approximately 25,000 mAh, there are a significant number of options for what and how to charge such an external battery.
A separate point I would like to highlight is the issue of choosing a specific model based on the capacity indicator. For example, if your smartphone has a rechargeable battery with a capacity of 2500 mAh, the optimal solution for charging it would be an external cell with a capacity of 3000-3500 mAh. There is no point in taking less; you can try more, but it will be clearly unnecessary.
For example, to fully charge the same tablet We can recommend using an external battery with a capacity of about 5000 mAh or even more, depending on the screen resolution, diagonal, and other performance indicators. This is really the best option, given that models that are too “capacious” are also too “expensive”; they simply will not pay for themselves.
Still, I would like to analyze the issue of using high-capacity external elements to charge conventional smartphones. Let's imagine a situation: your phone has a battery capacity of 2500 mAh, and the charger has 10,000 mAh.
At first, you may be happy about the possibility that such a capacity will be enough for as many as 4 (!) full charges, but in practice everything looks completely different.
The approximate number of charges will vary within three, and the reason for this factor is extremely simple. First of all, the minimum self-discharge of the battery is relevant, and an external battery is actually no different from a regular one, just in its location outside the phone and with a larger capacity.
Over time, the capacity indicators, just like when using conventional batteries, will deteriorate.
It is worth noting such an indicator as the voltage, which in external type batteries is set at approximately 3.7 V, which, let’s say, may also depend on the overall charge level at the current time.
Therefore, the value can change either up or down. If we talk about the Power Bank, its voltage is 5.0 V, provided that there is some circuit inside that helps increase the voltage to the required value.
This circuit also has its own efficiency indicator, which differs for each manufacturer. To ensure the most reliable and full charge of your mobile device, when choosing, you should add another 30% to the capacity of your battery.
There are no specific preferences regarding the appearance of devices; “design” is an individual choice for everyone. I just wanted to note the advantages of choosing devices housed in aluminum cases, which, as practice shows, are more resistant to mechanical and other types of impact.
The bottom line is that during the operation of the product, situations will arise in which it is subject to damage during prolonged wear, often inaccurately, to various impacts and deformations.
If the case is plastic, the likelihood of it being damaged remains extremely high, which will ultimately force the owner to go to the store very soon to get a replacement.
Among others, aluminum, of course, although a fairly soft metal, will protect the structure from possible deformations and will not allow plaque to form on the surface.
As you can see, choosing an external battery is quite simple and does not require decisive action or much thought from the buyer. But if the choice is made correctly, you can forget about the sudden discharge of your mobile device for a long time, at least until the battery becomes completely unusable.
Video material:
The phone always runs out of charge before an important meeting or during a business call, and the tablet “dies” a couple of minutes before winning the game. A portable charger will help you avoid unpleasant situations. How to choose exactly such an external battery so that it has the maximum number of charges? Suitable for both phone and tablet? In the review you will find the main technical characteristics that you need to focus on when choosing, and reviews of different battery models.
Just 10 years ago, phones worked perfectly without recharging for a week. Today, a device performs so many functions that its battery needs to be recharged regularly. In order not to ask employees for a charger and not to run around the shopping center looking for an outlet, it is better to just stock up on a portable charger. The battery can be carried in your pocket, bag, or in the glove compartment. But how much it can weigh and whether it can charge one or 2 devices several times is a separate conversation.
Power Bank, or external battery, is a portable power source for charging any gadgets. It consists of batteries (from 2 to 10) connected to the controller board. The battery has 1 or 2 USB ports to which you can connect a phone, tablet, video camera, camera, etc.
The device works like a storage device. First it charges from the mains, then generously shares energy with any connected devices.
Before you start choosing a model, you need to decide:
In practice, buyers choose a portable battery based on the size, design and color of the case. Then they buy a new one if this one is not satisfactory. It is much more practical to immediately take into account the main technical characteristics. The most important of them is the capacity of the device.
The main task of the battery is to release the accumulated energy. The question is how much the Power Bank can hold and deliver, this is capacity. The capacity is usually indicated on the case or in the device documents.
Advice. If you liked an external battery with an impressive capacity and a relatively low cost, then most likely it is a fake with low-quality components.
The difficulty is that the amount of energy received and transmitted is slightly different, because some of it is lost during the transmission process.
Some unscrupulous manufacturers, taking advantage of this moment, indicate the amount of energy received rather than given. Experiments have shown that the average amount of transmission losses is 20-30%. This means that a charger rated at 1000 mAh can charge a smartphone at 700-800 mAh. It is almost impossible to check this when purchasing, which means you need to choose products from well-known brands.
Attention! It is better to purchase a charger with a capacity that is twice that of a phone or tablet battery.
If your phone has a battery capacity of 2800 mAh, a charger with a rating of 5600 mAh or more will be suitable for it. If you are charging two devices, then you need to add their capacity and multiply by 2. And when purchasing, be guided by this figure.
The average option can be considered a Power Bank with an indicator of 6000 mAh; with it you can charge a smartphone within 2-3 days. A universal version with 12000 mAh is suitable for phones and tablets
The output current is the second parameter that needs to be taken into account when choosing. The fact is that the current strength partially affects the charging speed of the device.
Attention! Owners of Apple tablets will benefit from a 2A charger. This indicator is usually indicated on all portable batteries next to the connector.
Standard USB port with a current of 1A for phones and 1.5-2A for tablets. When purchasing a battery, you need to ensure that the charging current matches the device you are going to charge. Or choose a universal battery.
Apple iPhone, video cameras and players match the battery, which has a current strength of 1A. For iPad this figure increases to 2A. This means that if you are going to charge your phone and tablet at the same time, you need to select an external device with two connectors, 1A and 2A.
Theoretically, you can charge a smartphone with a 1A rating through a 2A connector and it will “come to life” faster. Or, conversely, charge the tablet through the 1A port, which will be much slower. But it is better to follow the device manufacturer's recommendations.
The input current refers to how quickly the battery itself charges. The same principle applies here. The current strength must be equal to or exceed the battery capacity, then it will be recharged at high speed.
On the one hand, I want to use a light, compact battery that fits in my pocket and won’t weigh it down. On the other hand, for full, comfortable charging, a large capacity is required. How can you find the optimal ratio?
Attention! Experts warn that small, cute batteries with a large capacity do not exist in nature! The higher the capacity and the more connectors on the charger, the larger and heavier the device itself will be.
The way out of the situation is simple; you need to choose a Power Bank based on individual needs. Calculate how many times a day you need to charge one or two devices. In accordance with this indicator, purchase a battery. Experienced users advise adding a small margin to the resulting figure. In case you decide to go on vacation with friends and share exercises with them.
You can often see batteries with additional capabilities on sale. Let's list the most popular "chips":
In design and color, portable chargers can be bright and interesting or strict and businesslike. For example, the Gmini company produces batteries that look like stones.
To questions like: “Which portable charger is best to buy?” Experienced owners of high-quality devices unanimously advise not to save money, but to purchase batteries from trusted brands. A lot of examples and photos with a battery and two bags of sand in a beautiful case make you doubt Chinese-made products.
Experts believe that the average cost of a high-quality Power Bank is $40. Buying an external device on the Internet can be much more profitable, but it is still better to purchase it in a store where they provide all the documents and a warranty.
Briefly about the main thing It is not necessary to purchase an external battery from a well-known brand, since it is no different in reliability and performance from models from lesser-known manufacturers. That is why we chose the most affordable devices that will never let the user down. |

Best external battery The best external battery today is the model. It is the optimal choice in terms of price/quality/performance ratio. | Best power bank with flashlight If it is important for you to purchase a model with a flashlight, but so that it also has high technical performance, then you can give preference. Although its battery capacity is slightly smaller than that of the Xiaomi model. |
Modern people prefer to use smartphones instead of tablets and laptops because they are just as productive and at the same time more compact. But due to their small dimensions, their battery life is reduced: it is impossible to install a capacious battery in a small case.
To solve the problems that arise due to this, you can purchase an external battery for your phone. You will learn in the article how to choose, what characteristics to pay attention to and which models are the most popular today.

An external battery (another name for Power Bank) is designed to charge a smartphone or other mobile device if there is no access to power supply networks. To do this, the device is connected to a mobile gadget using a special adapter cable.
Using a second battery to replace the main one is not always convenient. In addition, many modern flagship smartphones have a die-cast case in which the battery is non-removable. In this case, using a Power Bank is the best option.
An external battery is a set of batteries interconnected and enclosed in a case that has a universal output (usually a USB port) for connecting an adapter. The case is made from plastic (cheap models) or aluminum.
After connecting the smartphone to the Power Bank, the standard charging process will begin. These steps can be repeated until the external battery is completely discharged. Due to the fact that it has a large capacity, you can simultaneously or one by one charge two or more gadgets, or one mobile device several times in a row.
When choosing an external battery for your smartphone, pay attention to the main characteristics that will help you choose a high-quality and durable device.
This is the main characteristic that determines the performance of an external battery. It shows how long the device will provide the mobile gadget with energy.
This parameter is measured in ampere hours (Ah) or milliamp hours (mAh). For a Power Bank to work effectively and not cause any problems, its volume must be at least 2 times the battery capacity of the device it charges. But the larger this parameter, the better.
The larger the capacity of the external battery, the longer its operating period. But this increases the recharging time.
In addition, it is worth considering that the larger the capacity of the selected device, the more expensive it will be. The golden mean is 6000 mAh models. A Power Bank with a capacity of 15,000 mAh or more is suitable for charging a smartphone or even a tablet.
The strength of the outgoing current affects the charging time of the device. The higher it is, the faster the smartphone will charge. For a mobile phone, the standard indicator is 800-1200 mA, for tablets 1500-2000 mA.
Good to know! It is advisable that this parameter coincide with the recommendations of the smartphone or tablet manufacturer.
Please note that the greater the capacity of the external battery, the larger it is, because more batteries are placed inside. But in this case, everyone chooses a model for themselves depending on the requirements that they place on it.
For fans of hiking, a Power Bank with large capacity and dimensions is suitable. And for users who recharge their smartphone in order to “sit” on social networks, a compact and less capacious option is suitable.
Avoid buying models that offer large capacity in a compact package. These are tricks that are used to increase sales.
Different Power Bank models may have their own characteristics.
The main advantage of the model is excellent quality, high reliability and affordable cost. Thanks to the metal case and large battery capacity, you can easily charge the same gadget several times in a row (5 times or more).
The presence of two USB ports allows you to simultaneously charge several devices, but their close location will not allow you to connect two massive plugs at the same time. In general, this is where the disadvantages of the model end, so it is the best choice for purchase.

Unfortunately, due to the large volume of batteries, the battery case had to be made square, which is not always convenient to use. In addition, it is made of plastic, although reliable. This made it possible to reduce both the weight and reliability of the Power Bank.
The current strength at the two outputs differs: 2000 and 1000 mA, so you can choose which device to connect where.
The presence of two USB ports, a flashlight and a battery charging indicator allows you to operate the device comfortably and easily. Although the flashlight is of average quality.

Glossy plastic made the device stylish, but easily soiled, so it will need to be wiped constantly. Although the cost of Yoobao YB665 is quite high, its range of functions and reliability will allow it to be used for a long time. In addition, the Power Bank comes with a charger and adapters for iPhone.
