External battery for phone with charge indicator. How to choose a portable battery

Choose a portable battery for your phone or tablet.

So, let's start by deciding for what purposes you choose POWER BANK.

The main purpose of a portable battery is to provide the smartphone with the necessary charge of energy in case it is discharged. Such devices today can have a different capacity, it will last from several days to a week to ensure the battery life of an iPhone or other mobile gadget. At the moment, it is "Battery low" that are the universal saviors of any smartphone or tablet, acting as a source of additional energy.

What are portable batteries and how they work

An external battery will provide any mobile device with the necessary charge if its own battery has depleted resources. The principle of operation of the device: the batteries are connected to a small controller board. Connectors are attached to it for charging the smartphone and the device itself - the battery. The better the components used in it, the more reliable the entire design of the external battery and the longer it will last.

Accordingly, it is better to buy devices that are not too cheap, as there is a risk of getting a low-quality device. Inexpensive external batteries may have "crooked" assembled cells and low-quality parts. So it's better not to risk it.

External battery specifications

There are three important aspects that you need to pay attention to when choosing a device.

First: portable battery power

This is the main characteristic that determines the amount of time that the battery can support a tablet or smartphone with energy. Or, to put it simply, this is the time that a portable battery can operate without mains power. The power of the device is measured in milliamp-hours - mAh. In order to forget about worries about a dead mobile device, it is better to choose an external battery with a capacity twice as large as that of the gadget itself. If the iPhone 6 battery has a capacity of 1,810 mAh, then you need to take an external battery of 3,500-4,000 mAh to help. It will easily provide the smartphone with a charge in one full charge.

The best option for gadgets of any model is an external battery with a capacity of 6,000 mAh. It will make using your smartphone comfortable for a couple of days. But a device with a capacity of 12,000 mAh or more can be called a universal soldier, because it can recharge two devices at once with the same quality - a smartphone and a tablet.

Second: Discharging current

A connector with a current strength of 1 A in a portable battery is suitable for charging a smartphone, and 1.5 - 2 A for a tablet. To be more clear, the current in the battery affects the speed of recharging the connected smartphone or tablet. It is necessary to control the coincidence of the battery current and the specifications of the manufacturer of the mobile gadget. Therefore, it is best to choose a portable charger suitable specifically for a particular model, for example, for iPhone - with a current of 1A, for iPad - with 2A. Yes, and charge the iPhone from the 1A connector, and the tablet from 2A.

How to find out the current strength? It is indicated in the markup next to the USB port.

Third: Dimensions and weight

• The dimensions of an external battery directly depend on its power and the number of ports for recharging. The larger the capacity of the device, the larger its dimensions.
• Therefore, you need to select a portable battery for your gadget. If you just like to chat on social networks from time to time, then buy a small device, but if you are a businessman and need to constantly use a tablet, then get a powerful battery with a capacity of 10-15 thousand mAh. And remember, in an inexpensive device there can not be much power, look realistically at life.
• In addition, a rugged case, a solar battery or a built-in flashlight usually add to the price of the device. But these are not so important features that should be emphasized, so why pay more.

Chooseportable battery essentials

• So, a portable battery should have a capacity of 6,000 mAh for a smartphone, or from 12,000 mAh for a tablet.
• The device must have a 1A connector, or two connectors for 1A and 2A.
• The mass of the external battery can be about 250 grams.
• The device must be equipped with energy level indicators, a power button.
• Everyone chooses the appearance and other functions according to their wallet and taste.

What should be the costquality portable battery

• If we disassemble one of the most popular external batteries with a capacity of 10,400 mAh, then its cost may consist of the following components:
• Four Samsung ICR18650-26F batteries - $25
• Electronics, assembly and packaging - from 10 to 20 USD
• Transportation costs and income of the seller - from 5 to 10 USD.
• As a result - 40-60 USD or about 1300-1900 rubles (at the rate of 33).
• The important thing is that you should not believe the prices at well-known Internet auctions, when only 600 rubles are asked for a device with a capacity of 10,000 mAh, or a battery with a capacity of 20 thousand is offered for the same price. This simply cannot be, so do not believe in tempting cheapness. It is better to choose products from trusted manufacturers, study their technical characteristics.

How many times have you had to suffer from discharging your smartphone at the most inopportune moment? And if you need to call urgently or wait for an important message? It’s good if there is an outlet or a computer nearby, from which you can quickly charge the device. But what if they are not? The way out is to use an external battery (power bank). The Internet project "Be mobile" has collected tips that will help you choose the best option for you.

First, let's define what an external battery is and what are its advantages. An external battery or Power Bank is a portable high-capacity lithium-ion battery that can charge a variety of mobile devices: phones, smartphones, tablets or e-books. This battery is capable of storing energy within itself for a long time. You can take it with you to work, study, on a business trip or while traveling.

The portable charger can be made in various form factors with a plastic, polycarbonate or metal case. On sale you can find models in the form of boxes, bars, discs, cones and tubes of various colors.

The Power Bank is charged from the electrical network or from any device with a USB output (for example, a computer or laptop).

All external batteries are equipped with one or more USB ports. Modern phones, smartphones or tablets can be charged using a USB cable, which in most cases is included with the device.

id="sub0">

The main parameter when choosing an external battery is energy intensity. Everything is simple and clear here. The larger the capacity, the more energy the device stores, and the more expensive it is. Capacity is measured in mAh - milliamp hours.

On sale at present, you can find portable chargers with a capacity from several hundred milliamp hours to several tens of thousands. You can estimate the level of charge that you need based on the battery capacity of your smartphone or tablet.

For example, in an average smartphone, the battery has a capacity of 2,000 mAh, in productive and expensive models - from 2,500 to 3,000 mAh. This means that a fully charged external battery of 5,000 mAh is enough for 2-2.5 charge cycles. A fully charged 10,000 mAh external battery will last for 4-5 cycles. If portable charging is necessary for the tablet, then you should choose from models with a larger capacity, for example, 20 or 30 thousand mAh.

The current portable power sources are equipped with lithium-ion or lithium-polymer batteries. Depending on the type and design, the nominal battery output voltage may vary (3.7V, 4.2V, or 7.4V), while the standard USB power rail voltage is 5VDC. Obviously, in this case, a 2000 mAh battery with a nominal voltage of 3.7 V, even under ideal conditions, will not work for even an hour and a half when powered by an external load connected via the USB bus and consuming a current of 1 A. In addition, the amount of electricity that can be stored Batteries having the same capacity but different voltage will be different.

Tip 2: look at the current strength, it affects the charging speed

id="sub1">

Another factor that affects the charging speed is the current strength. The more amps, the faster the charging speed. For phones and smartphones, this figure must be at least 1 ampere. Otherwise, the process itself will be extremely slow. It will take 3 or 4 times longer to fully charge than from the mains.

For tablets, devices with a current strength of 3 A or more will be preferred. The ideal option is 4 A.

Tip 3: trust, but verify, because the declared capacity does not always match the real one

id="sub2">

Another important point is the real capacity of the Power Bank. The fact is that many manufacturers embellish the performance of their products. Of the 50 portable chargers we've been testing over the past year, 46 had significantly less capacity than advertised. The average difference was 25%.

For example, the manufacturer indicated that the external battery has a capacity of 10,000 mAh, but in reality - 7,800 mAh. The difference is connected both with the dishonesty of the developers and improper storage of batteries during transportation and subsequent sale.

id="sub3">

The real capacity is also affected by such an indicator as self-discharge.

On average, external batteries with a full charge within two weeks are discharged by 5%. This should be taken into account if you do not use Power Bank for a long time. To activate electrolytic reactions, it is worth putting the device on recharging before use.

Keep in mind that battery capacity will decrease over time. Our measurements show that with active use, a high-quality battery loses its capacity by 15% per year, the cheapest models - 35%.

To control the charge level, almost all Power Banks use LED indicators. And some external batteries are equipped with LED displays that show the exact state of charge in percent.

Tip 5: choose a power bank with multiple USB ports to charge your friends smartphones at the same time

id="sub4">

Some models of portable chargers have several USB ports for connecting two, three or even more mobile devices at once. This option is suitable for simultaneous recharging, for example, when you go on a trip with friends. It's comfortable. Together you can charge your phones, smartphones and even tablets.

Often you ask us where you can guarantee to buy a high-quality external battery cheaply. We cannot give a definite answer. Of course, the reliability of a purchase in a large Russian online store or in a retail network is higher, but the prices there are also higher. It is worth remembering that little-known Chinese sellers have a peculiarity: they can deceive. Their external batteries are much cheaper than branded counterparts, often they indicate the volume is 2 or 3 times higher than the real one. Too low a price can be a trap. Although branded Power Banks in such stores can be fakes.

Compact

id="sub5">

If you need compactness, you can pay attention to ergonomic models, for example, Anker Astro E1. This battery will not take up much space in your bag or pocket.

Universal

id="sub6">

The ideal option would be batteries with a capacity of about 10,000 mAh. This is about three times more than the battery of a modern smartphone, which means that even taking into account the loss of energy during recharging, it will be enough to fully restore the charge of the gadget several times. A good example of such a power bank is the Anker PowerCore 10400 mAh model.

Another option for a high-quality external battery with universal functionality is Aukey PB-N42 10000 mAh.

Supports fast and wireless charging

id="sub7">

If universal options are not your option, then you should pay attention to models with additional features. For example, a power bank with support for fast charging will be able to charge compatible gadgets much faster than usual. If the battery is capable of delivering a consistently high current (about 2A), then even without support for fast charging, your gadgets will charge stably and relatively quickly.

Among those recommended by us is the Baseus Wireless Charge Power Bank 8000 mAh external battery. Its main feature is the presence of Qi wireless charging. That is, to charge a smartphone - you do not need to connect a wire to it, just put it on an external battery and that's it. Charging started. In addition to wireless charging with a current of 1A, the device supports a wired USB connection of two compatible devices, while the output current to the USB connectors is 2A.

A good option for the iPhone is the Zikko PowerBag 6000 mAh external battery. The main difference from the popular Xiaomi external batteries is the MFI certification, that is, the battery is compatible with all Apple devices. The device supports fast charging - the output current to the USB connectors is 2.4 A. In order to track the battery capacity, there are special LED indicators on the end. A nice bonus - the smartphone is connected to the battery via the supplied Lightning cable.

With a record capacity

id="sub8">

If you're looking for a strategic boost of power, check out the 26,000mAh HyperJuice AC Battery Pack. This giant can quickly charge absolutely any device, including a tablet, other portable equipment and even a laptop. There are 2 USB outputs here. One provides a maximum charge of 3A at a voltage of 5W, and the other provides a current of 2.4A. A nice bonus is the ability to provide 220W power to any electrical appliances with a power consumption of up to 100W. You can connect a laptop, a flashlight and even a blender to such a battery.

The HyperJuice AC Battery Pack is made of aluminum alloy, which perfectly protects the device from external mechanical influences.

We hope that our advice will help you buy a truly high-quality external battery and charge your phone, smartphone, laptop or e-book without any problems.

Being always connected has become very important these days. Too much sometimes depends on whether a person can answer the call. In addition, phones also provide us with many options. To check the weather, get your bearings or contact a friend, you need a smartphone with a charged battery. And to help charge it while away from home, called Power Bank. How to choose the right external battery and not sit in a puddle will be discussed in our article.

Reasons to use an external battery and how it works

Power Bank is a portable battery for your smartphone, phone or tablet. It is designed to help you charge your device wherever you are. This can be useful in a variety of situations:

How does such a useful device work? Actually, it's just a battery that you can plug your smartphone into. After connecting, it begins to give off its energy as long as the charge remains in it. When the Power Bank runs out, you will need to charge it from a wall outlet, but a good battery will last you several times to fully charge your device.

Recharging the Power Bank itself takes a long time. It's best to leave it plugged in overnight.

Comparison of prices for Power Bank from different manufacturers

The first factor that you should pay attention to when choosing a Power Bank is its manufacturer. Products of different companies differ both in price and quality. It makes no sense to consider Chinese products from small manufacturers, since the percentage of fakes in this market is very high. Let's focus on comparing relatively well-known brands, and as a starting point, take their products with a battery capacity of 10000 mAh:

• Power Bank Samsung 10000 mAh - a device from Samsung is available at an affordable price - from 1800 rubles. For this money, the user receives a convenient 10000 mAh Power Bank without any frills. The maximum current of the device is 2 A; Samsung makes quality Power Banks at an affordable price
• Sony CP-V10 - Sony offers us a stylish-looking Power Bank for 2590 rubles. The device in a plastic case weighs about 250 g and supports a maximum current of up to 1.5 A. The standard connector is micro-USB; Devices from Sony are a little more expensive, but they look stylish
• Xiaomi Mi Power Bank 10000 - Xiaomi, as usual, is trying to win at the expense of a low price. Their device will cost you only 1700 rubles in local stores, and when ordering from the manufacturer - even cheaper. Maximum current - 2.1 A;
  Power Bank from Xiaomi is presented in different colors, and also has a low weight
• Power Bank REMAX 10000 is a Hong Kong company that is not well known in our market. In this regard, the price of the device in our stores is at the level of 1500 rubles. Judging by the reviews, the actual capacity of the device may not correspond to the declared one, so it is worth checking accordingly before buying. Maximum current - 2 A.
  REMAX produces cheap devices, but the quality is questionable

Price comparison table Power Bank from different manufacturers

Firm	Name	Current (A)	Price (in rubles)
Samsung	Power Bank Samsung 10000 mAh	2	1800
Sony	Sony CP-V10	1.5	2590
Xiaomi	Xiaomi Mi Power Bank 10000	2.1	1700
REMAX	Power Bank REMAX 10000	2	1500

As you can see, the price mainly depends on the popularity of the manufacturer. So, the device from Sony turned out to be the most expensive device, despite the fact that its current carrying capacity is the smallest. Well, choosing cheap and unverified companies, you risk getting a low-quality device.

Criterias of choice

So what should you pay attention to when choosing a Power Bank, besides its manufacturer? It is recommended to carefully study the following parameters of the device before purchase:

• battery capacity - above we considered devices of the same capacity to indicate the difference in price between them. But at the same time, the capacity of the Power Bank can be very different. The average capacity is up to 12 thousand, and it will be enough to replenish the charge of the smartphone several times. Devices with a capacity of about 20 thousand mAh are considered high-capacity Power Banks. If you see a device that promises you a capacity of about 50 thousand, then this is probably a fake. You can check the capacity of the device by knowing the capacity of the battery of your smartphone, or using special devices;
  The size of the device directly depends on the capacity
• additional functions - a flashlight (in case of a power outage), a detailed display of the remaining charge, several USB ports and other features can be found in Power Bank. There is no optimal set of properties, but additional features are always nice;
  The built-in flashlight can be useful when there is a power outage
• current strength - this indicator affects the charging speed of the device that you connected to the Power Bank. 2 A is useful for tablets, while 1 A is more commonly used to charge conventional smartphones. It is recommended to look at the current requirements of your device and follow them;
  You can find out the current strength on the device itself
• weight and dimensions of the device - there are no recommendations here. Of course, a lightweight Power Bank will be more convenient to carry around, but most often you have to pay for this with its capacity. The weight of the average device is 250-300 g. When choosing, you should be guided only by your own convenience;
  Power bank sizes can vary greatly
• device compatibility - a modern Power Bank uses a regular micro-usb connector to connect a device. He himself is able to charge via usb. This means that you can easily connect smartphones and tablets for recharging, but a laptop, on the contrary, will charge your Power Bank.

  Outcome

  Summing up, we will correlate all the characteristics in order to help you with the choice of device. So, you should pay attention to devices with the following parameters:

  The main thing, when choosing, be guided by common sense. If something sounds too good to be true, it is most likely a hoax. Choose your place of purchase wisely so that you can return the device under warranty if something goes wrong.

  Features of using the device and caring for it

  After buying a Power Bank, it is worth studying the features of operating the device. The fact is that if used incorrectly, the device will not only charge your smartphone more slowly, but will also fail faster. Here are the main recommendations for working with any Power Bank:

  
  

  There are no special features in the direct care of the device. All the advice that can be given here is very obvious:

  • You can clean the battery with any damp cloth. It is worth squeezing it carefully so that water does not get inside the device;
  • In addition to heat sources, it is also worth keeping the battery away from open flames. Batteries explode when heated, which can not only damage the device, but also cause serious injury.

  Power Bank very quickly entered our lives and began to be used everywhere. A convenient external battery will allow you not to be left without communication at important moments. And now you know how to choose such a Power Bank for your smartphone.

Have you ever looked for an outlet under the table instead of looking at the menu during your lunch break? Or have you encountered the phenomenon of worldwide redneck when in public places like an airport or a bus station, you were asked to gild a pen for 15 minutes of charging the device? If yes, then a) how we understand you; and b) it's time to do something about it!

The average smartphone sits down during the day. The tablet can be planted somewhere in 8-10 hours, laptops work even less (5 hours in active use is already an achievement). So if you are not the owner of the Apple iPad Air with its 12 hours of operation, an external battery will help you!

Preparatory stage

Dear reader, the following information requires the inclusion of the brain :-). Because it is impossible to buy an external battery, relying only on the budget, size, color and case material. You're throwing money away with this approach. We guarantee you this.

So, in order to choose the right external mobile battery, you will need the following information about the device for which you are making this purchase:

• Battery capacity;

For most smartphones / tablets and laptops, this indicator is measured in mAh: modern smartphones, on average, have batteries with a capacity of about 2,800 mAh, small-format tablets - about 4,000 mAh. The battery capacity of Apple devices is traditionally measured in Wh (Apple iPad Air, for example, has a 32.4 Wh battery, which means 11,560 mAh, and the new one has 6.9 Wh, i.e. 1,810 mAh).

The laptop battery, depending on the price category of the device, can have a capacity of 4400 mAh (48 Wh) or more.

• current strength;

We look at this parameter on the "native" charger. Usually, smartphones can be charged at a current of 1A, for tablets you need 2A, and for laptops - from 2.5A.

• connector type.

Most batteries use USB / microUSB cords or have a sufficient set of plugs / adapters in the package. But there are exceptions. What should interest you? Does the complete set of an external battery for a tablet / smartphone / laptop satisfy the connectors of your device. Fortunately, the harsh times of the mid-late 2000s, when even phones from the same manufacturer had different charging connectors, have passed and microUSB has become a common format.

By the way, when an external USB battery has not one, but several outputs, it is only to your advantage. So, in one device, ports for Apple products and devices charging from microUSB can be combined, or, as in the Power Bank JLW-658, there can be several ports with different current strengths - smartphones and tablets can be charged.

Please note that the price of an external battery will directly depend on the set of functions and capacity (this is clearly visible in the model reviews below).

External battery device

So, we already briefly know about the types and number of ports. Now about how different models can be arranged.

In most cases, external batteries have a charge indicator: this is how we find out both the degree of charge and the degree of “discharge” (sorry for the captaincy). The indicator can be made both in the form of an economical LED-backlight, and presented on a small display.

Additionally, various models can be equipped with, say, a flashlight (there is in the already twice-mentioned Power Bank JLW-658 battery - we hold the power button for 3 seconds, and - let there be light!), They can also act as a Wi-Fi access point (Kingston MLWG2 and MobileLite Wireless G2 from the same manufacturer - the best external batteries in this group), as well as read your flash drives for fast data transfer from the drive to third devices (for example, HooToo TripMate HT-TM01) or simply have a port for connecting an HDD.

Another interesting option is an external battery with a solar battery. Don't forget: external batteries also need to be charged, and they can also run out at the wrong time ... Therefore, a solar external battery is a great option for those who are used to having a backup option for a backup option :-) .

Charging the battery from sunlight is a rather rare option for ordinary electronics stores, but it is quite possible to find and buy such a device on the Internet. For example, the Eton FRX3 and HiNation HiLight models.

Plus, not every portable battery has to have a "brick" look: an external battery for the iPhone from Mophie, in addition to extra time for work, can also bring extra space for internal storage. Provided that you are ready to put up with the extra dimensions of a smartphone for the sake of such pleasant bonuses, the Juice Pack Plus model for the iPhone 5 from Mophie at 2,100 mAh is something that can help out in a critical “battery” situation, and the Mophie Space Pack, in addition to the charge , it will also add memory - + 16/32/64 GB for iPhone 5s / 5c.

We are also carefully looking at how you can charge the external battery itself: reviews about models that can only be charged from a laptop or computer are not the most flattering. Plus, the charging process itself in this way will be slower than if you connected the unit directly to the outlet.

Universal external battery

Yes, there are. More precisely, yes, you can choose one based on your needs. So, let's say you need an external battery for your smartphone, but you can't rule out the possibility of charging your tablet from it. Therefore, we choose with a margin: a battery with a capacity of 2x the capacity of a smartphone or 2x the capacity of a tablet (the second option is more acceptable, there will never be an extra charge), as well as a current that is greater than the current of the tablet. Why is that?

Because from a battery with 2A you can charge a smartphone designed for a maximum of 1A - the device will take exactly as much as it needs. But not vice versa. From weak batteries, you can also charge devices that require a higher current strength, but then the charging process can be noticeably stretched out, and such contact, if it is regular, will not benefit the devices. So all attention to the numbers, comrades! Let's act like educated people :-) .

Now, to consolidate, let's go through the models.

Typical external battery: Power Bank JLW-658

The products of the Power Bank company should not be confused with the English designation "power bank", i.e. "external battery" in our language.

The model has two USB ports, supports simultaneous charging of two devices. Ports on 1A and 2A, which allows you to charge smartphones and tablets.

You can charge the battery either by connecting to a computer or from a power outlet through a power adapter.

The delivery set consists of a cable for recharging via a USB connector from a PC, as well as an adapter for charging iPhone 4 and microUSB.

The battery charge is displayed on a digital display. There is a flashlight.

Model capacity: 13,000 mAh.

Full battery charge time: 11 hours.

Device dimensions: 105x73x23 mm.

You can buy Power Bank JLW-658 for 2,500 rubles.

Here's how lucky. Our boss at work ordered SITITEK Sun-Battery SC-09 solar chargers, the manufacturer indicated a capacity of 5000 mAh. The real capacity is slightly lower than the declared one, but in principle, three small gadgets can be charged.

Answer

Artyom 23.09.2015

I myself ran into nonsense (I bought 3 Chinese of different brands in a year, and after 3-4 months the capacity began to lose a lot, I had to look for a new one). As a result, I was satisfied with Remax. Although the Chinese, too, but the capacity is kept for a long time. Each time I test the purchased battery according to the principle, I divide its capacity by the capacity of the phone’s battery and see how many recharges will come out in reality. In general, I recommend Remax V6i Proda Jane Series 10000mAh!

Answer

Olesya 01.10.2015

Does the battery capacity have to be twice the capacity of the tablet? If I have a tablet battery capacity of 7000 mAh, and I buy an external battery with a capacity of 10400, for example, will it not be able to charge it to me at all?

A modern smartphone can be discharged at the most inopportune moment when you do not have access to a power outlet. And during some hike, difficulties are guaranteed - even the best smartphone models cannot work on a single charge for more than three days, while a trip to nature with a tent can drag on for a whole week. Fortunately, this problem can be solved quite simply - just buy an external battery. In this article we will talk about such a device as an external battery for a phone, how to choose.

Which brand to choose an external battery?

This niche of computer technology, of course, has its own production leaders, and these are the brands most often preferred by users.

Hyper

Products under this brand have existed for only a few years, but during this time they have won leading positions in various charts. At first, the manufacturer relied on a large capacity - its main models can charge even a 10-inch tablet, and more than once. But over time, the product line expanded, resulting in less capacious models.

Important! Initially, the batteries of this manufacturer had a rough design, but today the situation has changed - there are models on the shelves with attractive colors and elegant curves.

Remax

Under this brand, the largest number of portable batteries is distributed. The user can easily choose a copy for himself, focusing on his needs. Many models have built-in LEDs that act as a flashlight.

Important! The capacity of such batteries reaches 30,000 mAh - this parameter will be enough to even charge a laptop a couple of times.

Samsung

This is a South Korean company that introduces a large number of unique technologies into its smartphones. It would probably be strange if interesting functions were not found in the external batteries of this manufacturer. The main one is support for relatively fast charging.

Important! If the power is transferred to a compatible device, then recharging up to 50% occurs in just 30 minutes or even faster.

Pay attention to the review.

Xiaomi

This is a Chinese company that started producing external batteries quite recently. Previously, it specialized only in the production of smartphones. The main feature of Xiaomi products is increased reliability. These batteries are not affected by power surges or any other troubles.

Important! They also protect the device connected to them, which will definitely not get overcharged. We have prepared for you.

Yoobao

The location of this company is located in the city of Ginseng. Like many other Chinese manufacturers, this company relies on a low price for its products. The company also strives to make its range as wide as possible: some external batteries are shockproof, others have increased current and two connectors for connecting devices, and others surprise users with their miniature size.

Important! Here, the Chinese pedigree still makes itself felt - there are a large number of defective products, the capacity of which differs from the declared one.

Rating of the best external batteries - selection criteria

To make it easier for you to choose an external battery for your smartphone, we provide a rating that takes into account the following parameters:

• Price.
• Number of connectors.
• Equipment.
• Dimensions.
• Appearance.
• Real and declared value.

Important! Whichever of the batteries you choose, the information will be useful for you.

Best portable laptop batteries

To begin with, consider compact devices for recharging mobile gadgets.
