Power bank is one of the most popular types of accessories for smartphones, tablets, cameras and even laptops. Not a single active user of mobile devices can do without external batteries, because, despite the versatility and implementation of the latest technologies, the battery reserves of most devices melt before our eyes, which is very inconvenient not only when traveling and during outdoor recreation, but also in everyday life . After all, it’s not always possible to find a free outlet everywhere, and if you do, you’ll have to spend a lot of time waiting for your phone or other portable device to finish charging.

A properly selected Power Bank saves the situation. These compact, relatively lightweight and easy-to-use accessories make it easy to charge compatible equipment anywhere in the world, even on the go. You just need to connect the external battery to your iPhone or other device and put the charging device on a flat surface or back in your bag. At the same time, most Power Bank models are very versatile due to the availability of various adapters and the ability to connect the proprietary cord of the device being charged. However, not every external battery fits absolutely all gadgets, even with a wide selection of cables. In addition to compatibility with the necessary connectors and useful additions, it is also recommended to pay attention to the capacity and maximum output current of the models, because it is these indicators that determine how much and how quickly the Power Bank will charge the device and whether it will charge.

The best inexpensive power banks with a capacity of up to 10,000 mAh

Although there are a lot of external batteries in stores that cost several tens of thousands of rubles, in most cases you can easily get by with a basic solution costing from 500 to 1,500 rubles. The capacity of such developments does not exceed 10,000 mAh, they are mostly devoid of additional functions, their equipment is usually limited to a micro USB adapter, and the output current is relatively low, which is why they are hardly suitable for charging a tablet or laptop. However, the capabilities of such a Power Bank are quite sufficient for normal charging of most smartphones. At the same time, low-power models are often distinguished by minimal weight and distinctive design.

A compact battery in the form of a stylish keychain weighing only 65 grams will be the best option for those who are energetic, love comfort and are constantly on the move. A miniature Power Bank with a wide choice of colors and a stylish strap is convenient to take with you, because it can be easily turned into an unusual accessory for a bag or backpack and even put away in a small lady’s clutch.

Of course, such a small device will not charge a powerful laptop, but the 2200 mAh capacity is enough for a mobile phone or camera. According to reviews, this is the best truly budget option, although not the most capacious. Despite the modest price, the development of a well-known Chinese company received a charge indicator, USB type A, micro USB type B inputs and even a micro USB cable. The battery is quite versatile and can charge any smartphone. In general, this is a successful and inexpensive solution for every day, designed for quick recharging of not too energy-consuming devices.

Rating (2019): 4.4

External batteries are useful when hiking and traveling. But when charging a smartphone or tablet on the go, it’s easy to get caught in the rain, drop the Power Bank in water or spill juice on it, thus losing an essential item. A waterproof case that saves vital battery parts will allow you to avoid a disaster. Such practicality is rarely found in such devices, and therefore it is a very valuable quality.

Water resistance is the main, but not the only advantage of Ritmix. The gadget is also equipped with a bright lamp with four useful modes: maximum, medium light, minimum and flashing SOS signal. Surprisingly, even with constant use of the flashlight, the battery lasts for 130 hours. After all, a capacity of 5800 mAh is a good indicator, especially in combination with an output current of 2.1 A. A convenient handle and magnet, thanks to which Ritmix is ​​installed on a metal surface, will be an excellent bonus.

3 Canyon CNE-CPB78

Simultaneously charge two devices
Country: China
Average price: 1,190 rub.
Rating (2019): 4.0

The most capacious external device in the rating is the Canyon CNE-CPB78. Its 7800 mAh can charge a standard smartphone 4-6 times. This is ideal for long trips when there is no access to an outlet. The type of built-in battery is Li-Ion, which withstands frost well without losing its capacity.

The model charges very quickly with a maximum output current of 2A. However, a common complaint from users is the slow charging speed of the power bank itself. And this is not surprising, because its input current is only 1A.

Canyon has two USB connectors, and the kit includes a cable for regular USB and an adapter to micro USB. With this device you can charge two completely different devices.

Externally, the plastic device looks stylish and neat. Dimensions of 65mm by 100mm make the device the most compact in the TOP-3. A nice addition to the Canyon CNE-CPB78 is a flashlight.

Review from user Dmitry:

Very powerful external battery. Perfectly charges devices more than once. For those who rent for the city, there is no point in such power, but I often go on business trips. The two outputs are also nice; at the same time I charge a smartphone for work calls and a smartphone player. There are no glitches, overheating, etc. The flashlight is very useful because you don’t need to search in the dark or install it by touch. Of the minuses: disgusting charging cable. I had to buy another one because this one charges practically nothing. And the battery itself charges very slowly, although this is logical, I would like it to be faster.

Review from user Igor:

I charge Xiaomi Mi Power Bank 5000 iPhone 6, the battery lasts almost twice. Doesn't heat up. It looks pretty nice, but most importantly it is reliable. I am completely satisfied with this model, especially for such a price it couldn’t be better. The downside is that it’s a little heavy for a pants pocket, but since the model is small, it’s convenient to put it in a jacket.

Having appeared relatively recently, this affordable model quickly became one of the best external batteries according to user ratings and took a prominent place among the record holders in terms of the number of positive reviews. The key to the success of the Xiaomi power bank was, first of all, the successful combination of an adequate price, an honest capacity of 10,000 mAh and capabilities that are rarely found in the budget segment. Power Bank 2S, unlike many analogues, allows you to charge two devices at once and even supports the Quick Charge 3.0 fast charging function.

A large illuminated display with a picture of the battery clearly shows how much charge is left. In addition, this Power Bank is not deprived of rare useful additions - a flashlight and a card reader. The former will undoubtedly be useful in nature and at home, while the latter will appeal to those who charge an external battery from a computer or TV, because Hiper can simultaneously charge and work with memory cards.

Unlike the previous representative of the HIPER company - EP6600 - this model does not stand out with an equally striking design. Before us is an ordinary white block with a standard set of ports (2 USB for charging devices and Micro-USB for charging the battery itself), a power button and a charge level indicator. But we should pay tribute to the engineers - the case is non-marking, durable, and scratches practically do not appear during operation.

There is little interesting in terms of technical characteristics: capacity 20,000 mAh, maximum current 2.1A. There is no fast charging, but it is enough for tablets. As a result, we have a practical, reliable and high-quality external battery for owners of devices without support for fast charging technology, who do not want to overpay for unnecessary functions.

How to choose the best power bank

Choosing an external battery to charge your electronic devices is not that difficult. There are few parameters to pay attention to. The main ones are listed below.

1. Battery capacity. Main characteristic. If you just need to keep your smartphone alive until the end of the working day, a 5000 mAh battery is enough. If you're going camping for a week, look at models with a capacity of at least 10,000 mAh. The following characteristic directly depends on the capacity
2. Dimensions. Fragile ladies are unlikely to want to carry an extra half a kilogram in their purse. Therefore, it is worth paying attention to the size and weight of the power bank. More capacity means more weight and dimensions.
3. Current strength. 1A is enough to charge a smartphone. For a tablet, 2.1A is desirable, otherwise charging risks taking longer or simply not starting.
4. Supports fast charging function. If your device supports any fast charging standard, it is advisable to choose the appropriate external battery. If the battery itself charges quickly, that’s generally great.
5. Number of connectorsUSB. If you plan to charge a couple of devices at once, choose models with two USB ports.
6. Protection. It will be very unpleasant if your brand new power bank catches fire. Choose high-quality models with protection against short circuit, overload and overheating.
7. Tests and reviews. If possible, watch the model tests before purchasing. It may be that the actual characteristics will differ significantly from those declared by the manufacturer.

For all mobile devices, autonomy is the weak link. A small amount of energy does not allow the user to fully enjoy the possibilities during the day. If we talk about flagship models, then the active work time can be several hours. For a long time, society had to carry a charger in a bag and depend on an outlet, but modern power banks have completely eradicated this problem. Different styles and case materials, total usable capacity and charging technologies allow you to choose an external battery for a specific smartphone or group of devices.

Among the large assortment, Xiaomi products stand out. The popularity of the brand is rapidly increasing, and in the production of power banks it can already be called a leader. The company achieved this result with an optimal combination of cost and characteristics.

The Singaporean Rombica and the American Goal Zero were awarded entry into the premium segment. Both companies make professional external batteries for charging any device. The main feature is the combination of the familiar with the high-tech - solar panels, inverters.

HARPER has successfully gained a foothold in the middle segment with a focus on tourism. The devices have increased durability and functionality for survival in extreme conditions.

The budget segment has always been the most popular, which is why a large number of Chinese craftsmen work here - Asus, TP-Link and Yoobao. They were joined by the European brand Hiper and the American Canyon. Their main task is to provide users with autonomy, so the devices have a large capacity.

In the development of the mobile gadgets market, there is a persistent tendency towards a decrease in the battery life of all devices, which is associated with an increase in their productivity. If previously push-button phones worked continuously for about a week, now 2 days without charging is already a very good indicator for a modern powerful smartphone.

You can avoid sudden discharge of your device, which usually happens at the most inopportune moment, by using a power bank - a portable power source. In this article you will learn how to choose an external battery and which brands you should pay attention to.

How it works

PowerBank is practically no different from the battery in your laptop or smartphone. Inside its case there are several batteries that are connected to each other by a controller board. On one side of the power bank there are connectors for connecting other devices, usually USB and MicroUSB ports.

Externally, most of these batteries resemble an ordinary bar with a minimalist design. There are also models with original design. Another type of power banks is battery cases. They not only recharge your smartphone, but also protect it from falls.

The principle of operation of the device is extremely simple: it is charged from the mains and the batteries located inside the case retain this charge for a long time in order to release the accumulated energy to the connected device as needed.

If you do not want to make a mistake, choose an external battery taking into account the following characteristics:

• Compatibility;
• Capacity;
• Functional;
• Dimensions;
• Design;
• Manufacturer.

Below we will examine each of these aspects in detail.

Compatibility

First of all, compare the input voltage required to charge your smartphone or tablet with the output voltage of the external battery. You can find this data in the device documentation or on their charging blocks. Most gadgets require a standard voltage of 5V DC.

There are no strict requirements for current strength. Usually, 1 Ampere is enough for smartphones to charge; tablets require one and a half to two times more. It is advisable to adhere to these limits. In principle, nothing bad will happen if you connect a gadget with lower current requirements. The charge controller will automatically block the process if the permissible value is exceeded.

On the other hand, a power bank with a current of 1 Ampere is simply useless for charging a laptop. In this case, the device will take too long to charge or will not charge at all. The same applies to iPads, which require at least 2A, otherwise the device’s battery will not receive the required amount of energy.

Capacity

The most important parameter of almost any battery. It determines how much energy and for how long the battery can be transferred to another device. The value is measured in milliamp hours (mAh). The capacity of the battery directly affects its dimensions and the possible number of full charging cycles for a third-party device.

PowerBank uses two types of batteries: lithium-ion and lithium-polymer. There is a slight difference in maximum energy capacity between them, while lithium-ion batteries are the most common on the market.

So, to calculate the required capacity, think about how many full charge cycles an external battery should provide for your smartphone or tablet. This is very easy to do; just divide the capacity of the power bank by the same size of the battery of another device. The resulting number will be the number of complete charging cycles.

However, the information provided by manufacturers about their product is not always true. For example, a power bank with a capacity of 9000 mAh will never charge a smartphone with a 3000 mAh battery three times. The fact is that the efficiency of external batteries is not 100%.

Why is that? First, there is the phenomenon of battery self-discharge. The power bank loses charge even during inactivity. Secondly, the output voltage of the lithium-ion battery is 3.7V, which increases to 5V thanks to the output converter inside the device. Because of this, efficiency also decreases.

As a result, in order to more accurately calculate the number of complete charging cycles, the declared capacity of the power bank must be multiplied by a factor of 0.8. Based on the obtained value, it is already possible to carry out calculations. The ideal option for most smartphones is around 8000 mAh. This battery will last for several days, plus it won’t take up much space. For tablets you need at least 12000 mAh.

Functional

External batteries can also be equipped with additional functions. Here are some of them:

• Additional connectors. Large batteries can charge multiple devices at once via wired interfaces;
• LEDs. Most power banks are also equipped with LED backlighting to make it easier to find the right connector in the dark;
• Charge level indicator. A small display on the case shows the exact charge value of the power bank. With its help it is convenient to monitor the battery status;
• Solar battery. The surface of models of power banks such as PowerPlant is covered with a photosensitive layer that generates energy in sunlight. You won't go wrong if you choose this battery for outdoor trips and outdoor activities.

In other cases, external batteries can be equipped with cosmetic improvements such as a mirror or a built-in charging cable.

Dimensions

The size and weight of a power bank directly depend on its capacity. Logically, the larger the batteries, the more energy they can give to other devices.

In this matter, manufacturers have practically managed to reach the “golden mean”. An external 10,000 mAh battery weighs approximately 250 grams and is practically the same size as a diary. This model is enough for most everyday tasks. A power bank with a capacity of 20,000 mAh will accordingly weigh twice as much.

The weight of the device is also affected by the type of battery inside and the materials of the case. Lithium-ion batteries are slightly heavier than their lithium polymer counterparts. The metal body also adds weight compared to plastic.

Design

The appearance of a power bank is a matter of taste for everyone. The design of the battery does not in any way affect its technical characteristics. Nevertheless, it can play a decisive role in the choice for some buyers.

To increase the attractiveness of their devices, more and more manufacturers are relying on a unique appearance. Others, on the contrary, produce monoblocks in a strict design with a minimalist design. For example, Xiaomi. Most external batteries of this brand are made in one color and only have the designation “MI” on one of the surfaces.

Manufacturers and models

Among the variety of brands, we have selected the top 5 popular manufacturers of external batteries.

First place: HIPER MP10000

• Capacity: 10000 mAh.
• Cost: $25.

The HIPER brand is at the peak of popularity due to the good build and capacity of its devices. The MP10000 is rugged, versatile and compact (100x70x20mm).

The device body is made of aluminum, which protects the internal batteries from falls. There is a slot for microSD at the top end, so the power bank can also be used as a card reader. Wired interfaces are illuminated by an LED flashlight.

Second place: DBK MP-S23000

• Capacity: 23000 mAh.
• Cost: $125.

S23000 is a multifunctional, capacious power bank with a solar battery. Simultaneous charging is possible with a switchable voltage from 12 to 19 Volts. In the package, the buyer also receives several adapters for laptops and smartphones.

Overall, the S23000 is an excellent option for going on a hike or a picnic. The battery capacity allows you to charge and maintain the laptop a couple of times. The only drawback is the lack of low voltages for charging smartphones.

Third place: Xiaomi Mi Power Bank 16000

• Capacity: 16000 mAh.
• Cost: $45.

Xiaomi once again proves that a good device does not have to be expensive. For just $45 you can get a large battery for your tablet or smartphone. The nutritional cells are protected by an anodized aluminum housing.

Among the shortcomings, the impressive dimensions of the power bank (60.4x145x22) and the lack of an accurate charge indication stand out. With four LEDs, it can sometimes be difficult to tell how much longer the battery will last.

Fourth place: Xiaomi Mi Power Bank 10400

• Capacity: 10400 mAh.
• Cost: $23.

And another copy from the Chinese brand, this time intended only for smartphones. Despite the large capacity, it is very compact and reliable. By tradition, the appearance of the power bank is minimalist.

However, you can only use 10400 mAh for one smartphone at a time. The battery does not provide for simultaneous charging of several devices.

Fifth place: Rombica NEO PRO180

• Capacity: 18000 mAh.
• Cost: $125.

The high cost of this model is fully justified by the rich equipment and the presence of several connectors for charging both tablets and laptops. It is possible to adjust the output voltage from 12 to 19V.

The battery charge is indicated by an LED indicator on the side panel. Using a 19-volt cable, the device charges to 100% in 3.5 hours.

Conclusion

When buying an external battery, you should not chase a large capacity at the expense of size. As a rule, 10,000 mAh will be enough for most users for several days without recharging from the mains. In other cases, it is not advisable to purchase more energy-intensive batteries.

Also pay attention to the cost and equipment of the device, but do not be fooled by the low price. Sometimes tempting offers appear on Aliexpress for $20 for 20,000 mAh. But, most likely, this is a fake - little-known manufacturers are very fond of equipping power banks with batteries with a volume several times less than the declared one.

Also, many interesting models of portable batteries are presented in our publication ““.

Power bank (power bank among the people) is an external battery for a phone or tablet, for anything that needs to be recharged when there is no charger and 220V outlet at hand.

DOWNLOAD ALIEXPRESS MOBILE APPLICATION

Agree, this is a useful thing, for example, on the road, modern smartphones discharge quickly, and there is often simply nowhere to recharge them. How to choose a power bank so that it doesn’t hurt excruciatingly later?

How to make a Power Bank yourself?

It’s interesting that a few years ago there were no such devices at all, and Aliexpress was only in the project. But even then I made my own power bank from old laptop batteries:

It's primitive, of course, without any electronics, but it did its job. Now times have changed and for a few dollars you can buy power bank box , which will charge the batteries to the desired state and show you that charging is complete.

The beauty is that the choice of such devices is now very large, so large that it is sometimes very difficult to choose. If you are on aliexpress write in the search Power bank, then you will get 29,000 results!

And how to choose an external battery for a phone or other similar device among so many offers?

Which external battery is better?

I will not describe any specific models (except those that I bought myself), I will just tell you how to choose such external power supplies. What are they?

Already with batteries or just an empty box? When choosing, read carefully: is the device being sold COMPLETELY equipped (with batteries) or just an empty box for them?

Some were very disappointed when they bought a portable battery for their phone at a CHEAP, only to find out that it was just an empty blank and now they still had to buy batteries!

If you ALREADY have batteries at home, then it’s better to just buy a box, as it will cost you MUCH cheaper!

If you don’t have any at home, then buy a portable charger ALREADY equipped with “batteries”.

What batteries is POWER BANK compatible with: 1.2V or 3.7V? Yes, before choosing a power bank, CAREFULLY read what batteries are used in it. Sellers warn IN ADVANCE which batteries are suitable and which are not:

What type of batteries do you prefer?

TYPE AA at 1.2V - these are very common batteries, or “finger-type” batteries, as they are commonly called, but scientifically the type is “AA”.

Pros of AA batteries:

1. Availability. You can buy it at every step.
2. Replaceability. If the batteries suddenly run out, you can insert ordinary 1.5V AA batteries into the power bank.

Disadvantages of AA batteries:

1. Memory effect. It is advisable to always completely discharge such batteries and then fully charge them. It is not recommended to recharge, as the batteries may lose a lot of capacity.
2. Capacity. The capacity of these batteries is not great, so if you buy a power bank with just one element, it won’t last long.

I won’t write about the price, since it is high for all high-quality batteries. What can be said about the second type of battery?

TYPE 18650 at 3.7V — you can’t just buy this battery, you won’t find it in a store in your city (maybe only in Moscow?), but it’s EASY to get... from an old laptop battery, there are already several of them!

Pros of 18650 batteries:

1. No memory effect, since they are lithium-ion, like those on your phone, smartphone or tablet.
2. Large capacity. Due to their large size and other technologies, these batteries have a good capacity, so even one cell is enough to charge your phone more than once. The cheapest 18650 battery will have the same capacity as the most expensive NiCad or Metal Hydride AA battery.

Cons of 18650 batteries:

1. Rarity. You won’t be able to buy them in a store, and if you don’t have a broken laptop, then all you have to do is order on Aliexpress, there are a lot of them - 18650 BATTERIES .

So which power bank to choose on Aliexpress?

First, you can watch a video that talks about some models from Aliexpress:

10 BEST POWER BANKS WITH ALIEXPRESS

As you understand, it all depends on various factors and now you need to understand what is right for YOU, what you already have and how you will use it. Let me give you my example.

Initial data: I have a bunch of 18650 cells from an old laptop, and they're just sitting around, unused. From my practice, I noticed that even if the battery on a laptop no longer holds a charge, this does not mean that all its elements are faulty.

Most often, it happens that only one or a couple of outermost ones lose capacity, while the rest are still very functional. We disassemble the battery into parts, disconnect all the elements, and begin charging one by one.

sDon’t let it scare you that he hasn’t worked for a long time and has completely sat down. Look, I plugged a completely dead battery into my new power box and measured the voltage (it’s also from Aliexpress):

The voltage was below nominal, I didn’t start taking pictures right away, it was even less. Literally a few minutes passed and the battery began to gain capacity, the voltage began to increase and reached the working level:

Which power bank box did I choose? I bought the simplest one, this option for only $2.

The simplest device, plastic case, one cell, when charging the light blinks, when the battery is charged it stops blinking and no more current flows to the battery, so no recharging will occur. What else is needed for happiness?

The battery fit like original, charged for several hours and now I have a working power bank for only $2. But I didn’t stop there and ordered myself another Power Bank Box, but for 2 elements for only $3.5

It has an aluminum body, a discharge (or charge?) indicator, and a power button - it looks decent. I haven’t received it yet, but when it arrives, I’ll definitely add my feelings in the comments. This one can already be taken on a long journey.

I also ordered this one for myself USB TESTER , with the help of which you can find out what REAL capacity each individual battery has in order to weed out the dead ones.

To sum it up, we can say this: Which power bank is better to buy is up to you to decide, just buy the one that really suits you and that won’t cost you that much. If you have a lot of money and need a POWERFUL power bank, then buy this one for 13600 mA/hour -

Smartphones and tablets have become an integral part of everyday life. But they have an annoying drawback - mobile electronic devices quickly discharge when used intensively. It’s good if this happens somewhere where it is possible to connect the gadget to an electrical network. But what should those who don’t have an outlet nearby do? In this case, an external battery will come to the rescue.

What is PowerBank

A portable PowerBank is a small electronic device of a rectangular or cylindrical shape, inside which a rechargeable battery is located. The device is connected to a household electrical outlet and accumulates a charge. You can take it with you on a trip, to work, on a business trip, to classes. If your phone or other mobile device runs out of battery, you can recharge it using an external Power Bank.

The best Power Bank - how to choose? Very simple!

How to choose a PowerBank when there are so many of them on the market? Before you buy an external battery, you should collect as much information as possible about the model you like.

Capacity

This is one of the most important parameters that allows you to judge how productive the charger is. But larger capacity does not always mean “better” and “faster”. It is not uncommon for a universal external battery to produce at most half the power stated in the technical specifications. Most often this happens with so-called noname devices from unknown companies, in the production of which the technology was violated and low-quality electronic components were used.

Small portable ones have a capacity of 2000-2600 mAh. And the most powerful ones are 10 times more. To understand which Power Bank to choose, answer the question: “How much extra power will I need?” If you need to recharge your phone in case of unscheduled discharge, an external one with a capacity of 2000-5000 mAh will be quite sufficient. But if you need to be in touch almost all day without access to an electrical network or are planning a long trip, you will need a more powerful device.

Don't take the capacity issue too literally. If yours is labeled 10,000 mAh, and the phone's battery is 2500 mAh, this does not mean that you will be able to charge your smartphone four times in a row. Although from a mathematical point of view this is true, in practice any portable battery loses some percentage of energy. How large these collateral losses will be depends on the quality of the Power Bank.

Another important parameter for those who do not yet know how to choose a PowerBank for a smartphone is the brand. Inexpensive Chinese Power Banks are usually made from the cheapest materials. If the battery has a solid capacity of 10, 15, or even 20 thousand mAh, and the price is pleasantly pleasing to the eye, it’s better to pass by. For such a Power Bank, you can confidently divide the numbers indicated in the technical specifications by three, and it is not a fact that in reality you will get the declared performance. Branded ones are more expensive. But their real operating parameters correspond to those stated in the data sheet, and losses on average do not exceed 10-15%. But, ultimately, which PowerBank company to choose, everyone decides for themselves.

Size matters

When wondering which is the best power bank to choose, think about how you plan to store and carry it. The issue of size and weight is more important than it may seem. Capacitive batteries can weigh up to half a kilogram. For example, a PowerBank 20,000 mAh weighs from 290 g, and an external battery with a capacity of 30,000 mAh weighs 450 g. You won't be able to carry it in your pocket. A backpack is needed here. It is important to find a compromise between performance and device size. In some cases, a miniature PowerBank, slightly larger than a credit card, is quite sufficient, such as a model from the Dadget company called “” with a capacity of 600 mAh.

Mobile gadget charging speed

Portable chargers do a very good job of charging mobile phones and smartphones. The charging time is comparable to the waiting time when charging from the mains adapter. The situation with tablets is not so optimistic. They require much more time to recharge and not every Power Bank can cope with this task.

Power Bank Charging Speed

No one wants to wait a day for an external battery to be fully charged. A simple rule applies here - the more amperes, the faster the charging.

Frame

The material of the Power Bank case must be resistant to mechanical damage. You can buy a Power Bank with a casing made of or. Some manufacturers offer a combined charger - a portable device with a metal case and protective rubber pads that soften the impact when dropped.
