Power Bank 20000 mAh - the best models of high-capacity external batteries

The capacity of batteries built into smartphones is gradually increasing. We are no longer surprised by batteries with a capacity of 5000 and even 6000 mAh. To charge such a monster on the road, a low-capacity external battery will not work. To do this, you will need one of the 20,000 mAh power bank models. Many have heard of or are looking for Xiaomi Power Bank 20000, but the light has not converged on it. There are also more comfortable ones and with more interesting functions.

We decided to consider external batteries with a capacity of 20,000 mAh because of their wild popularity. Now this is the optimal parameter. Such a large battery is enough to recharge any smartphone several times. And this is also the best choice for the owner of a tablet computer!

Hoco B23B-20000

A very good product from a little-known company. The body of the product can be painted black or white. At the same time, the manufacturer tried to achieve a very small thickness. Of course, such an accessory won’t fit in a shirt pocket, but it certainly won’t take up much space in a backpack. There is a digital display on the front panel of the portable battery - it shows the charge level. Believe me, not all external batteries have such luxury!

The device supports an input current of 2 A. It turns out that fully charging such a capacious battery will not take a couple of days. As for charging other gadgets, there are as many as three USB connectors for this! One of them has a current of 1 A, the rest have twice this parameter. But it should be taken into account that the maximum the accessory produces is 2 A - when simultaneously charging several devices, this parameter will be divided by their number. In short, this is a very good, but not ideal option. The main advantage of Hoco B23B-20000 is its low cost in Russian retail.

Advantages:

• Three USB connectors for charging gadgets;
• Small thickness;
• Responsible weight;
• Clear charge indicator in the form of a digital display;
• The battery itself charges quite quickly;
• Adequate price tag.

Flaws:

• Rarely found in stores;
• Protection against short circuits and other troubles is poorly implemented.

Xiaomi Mi 2 Power Bank 20000

Xiaomi Mi 2 Power Bank 20000
External batteries from the Xiaomi Mi Power Bank 2 series have a number of features that distinguish them from both competitors and predecessors. Firstly, there is full support for Qualcomm Quick Charge 3.0 fast charging technology. This means that with the appropriate power adapter, you can charge your battery in 7-8 hours! This is nothing for such a capacity! Secondly, the output current here has been increased from 2 to 2.4 A. It seems that this is not enough, but most often this is what tablets lack for faster charging. Thirdly, the Chinese have done a great job of ensuring security. There is protection from everything here:

1. from short circuit,
2. from overheating
3. and from overload.

There is also a charge indicator on the case, which many less capacious batteries lack.

Are there any reasons not to love this accessory? The first thing that comes to mind is the rather high price. Well, after purchase, it all depends on whether you have a charger that supports fast charging technology. Without it, it will take a very long time to charge the external battery. There are also complaints about the plastic case, which turns yellow over time.

Advantages:

• The weight cannot be called very large;
• There are two charging connectors;
• The output current is 2.4 A;
• There is support for fast charging technology;
• Protection from all kinds of problems;
• There is a charge indicator.

Flaws:

• The casing may turn yellow over the years;

Without charging, it can share its charge with the phone 3 times. Owners also note the quality of workmanship - the charger is pleasant to hold in your hands - the case is made of aluminum.

HIPER PSX20000

Power Bank HIPER PSX20000
Many consumers pass by this external battery. The fact is that they are afraid of the very high cost. But if the buyer has not spared money, then he is completely delighted. This accessory turned out to be very thin and pleasant to the touch. There are no unnecessary elements on it, and the ideal appearance is maintained for many years. The manufacturer refused metal - in order to reduce weight, they decided to make the body plastic. Inside there is a high-capacity lithium-polymer battery, the charge of which is enough for both smartphones and tablets. The approximate level of the current charge is displayed on the corresponding indicator.

The main feature of the accessory is the large number of connectors. Traditional full-size USB ports are intended for charging gadgets - there are three of them (a pair with a current of 2 A, and one with half that value). Three connectors are also intended for charging the battery itself: microUSB, USB Type-C and Lightning. It turns out that you can charge the accessory using any cable!

Advantages:

• Different types of connectors are used to charge the battery;
• As many as three USB ports for charging gadgets;
• Very small thickness of the accessory;
• There is a charge level indicator.

Flaws:

• Only one body color available;
• The output current does not exceed 2 A;
• The cost may seem prohibitive.

How many times can you charge a smartphone?

When choosing an external battery, users divide the storage capacity by the device’s battery capacity, intending to calculate the number of charging times. A universal 9000 mAh battery will not charge a 3000 mAh phone three times - maximum 2-2.5 times. A 20,000 mAh battery will charge the device up to 7 times. Over time, the minimum charge characteristics deteriorate. The voltage of the elements used in external batteries is 3.7 V, depending on the charge level it changes up and down. Standard voltage (USB) is 5 V, a circuit is installed inside that increases the voltage to the required level. Battery models differ in efficiency. A voltage-reducing circuit is built into the device. Some of the energy is lost; a universal battery does not provide full capacity - you will need a reserve of 20-30%.

This means that smartphones supporting this technology will charge 1.75 times faster than when using any other power bank.

To recharge the battery itself, a microUSB connector is used here. Next to it you can see four holes - under them are hidden small LEDs that act as a charge indicator. There is also a large LED on the top end, which will be used as a flashlight. It should be noted that fast charging technology is also used when filling the battery itself with energy - as a result, this process takes only 7.5 hours. The accessory supports up to 5000 such cycles. This allows us to conclude that ASUS ZenPower Ultra will serve you for many years.

• There is a bright flashlight;

TopON TOP-T72

Price : 4,050 rub.
For a person buying a power bank, the most important thing is that the device can charge a laptop or phone without access to the Internet, and TopON TOP-T72 does this perfectly. The display shows the time remaining until fully charged, which is very convenient.

Sold in 2 colors:

• white;
• black

When the phone is charged, it lasts for 4 times, and after that the power bank needs to be recharged. The battery is lightweight and compact, so you can carry it with you even in a small purse. You can charge TOP-T72 via the built-in microUSB connector from the car's cigarette lighter or using an AC power supply.

Solar Power Bank 20000

Solar Power Bank 20000
Practice shows that small Chinese companies also produce good external batteries. For example, a very good example is Solar Power bank. This accessory comes with a carabiner, which allows you to carry it somewhere on your belt while hiking. The device is also packaged in a massive case, which acts as protection during impacts. The manufacturer also promises that its portable battery is not afraid of water. But we would not recommend throwing it somewhere into a lake - most likely the battery will not be damaged only during rain.

Another important feature of the battery is the presence of solar panels. Under bright sunlight, they try to recharge the accessory. However, don't think they get the job done quickly - it takes about 40 hours to charge from 0% to 100%. On the opposite panel there is a bright LED. Its purpose is to illuminate a tent or help you find something under your bed. Using Solar Power bank you can charge two gadgets at the same time. One of the connectors here produces a current of 2.1 A.
