We put the Xiaomi Mi 20.000mAh to the test, the best and inexhaustible external battery for your devices

The battery of our smartphone is neither generously large nor incredibly durable, although the relationship between performance and consumption of an iPhone is very good (which concludes that the iPhone are very efficient), the low capacity of its battery makes us live practically glued to the walls.

And that is something that other companies like Samsung have already taken advantage of in their advertising campaigns, iPhone users are "wall huggers", we need a nearby socket or we do not get a full day of battery (unless we do very little use of our device or we have a "Plus" version.

This problem, however, ends from the moment we get hold of a Extreme battery, and more if it is intelligent, of quality, has a fast charge and the capacity to be able to ask our much-loved plugs for some time for ourselves.

It is precisely about this battery that I come to talk to you today, in my opinion, the best external battery on the market, the Xiaomi Mi 20.000mAh.

Capacity

One of the star characteristics of this product is its large capacity, with 20.000mAh allows us (and will allow me) to hold out until 4 or 5 days of intensive use of our smartphone without having to go through a plug, and when I say intensive use it is continuous use; video recording, photographs, use of GPS, 4G navigation, use of Bluetooth, screen with maximum brightness, in short, a use that decomposes that precious efficiency of our precious iPhone and that the Xiaomi battery can compensate again with the ability to charge up to 8 times our device.

Fast charge

But so much capacity entails a big problem, recharging it, and this problem disappears thanks to the incorporation of the latest control chip of Texas Instruments (a veteran and reputable North American company known for its semiconductor manufacturing), this chip provides you with the ability to charge up to 11.000mAh in just 3 hours, without a doubt a dizzying speed that will allow us to keep up at all times, with just 7 hours we will have the battery fully charged.

Security

One of the most important aspects when buying this type of accessories, this and the capacity are decisive aspects in these accessories, and that is that there are batteries of up to 40.000mAh online for less than € 20, the problem is that they are cheaper its manufacturing costs by not integrating components that ensure the safety of said battery or the devices that are connected to them, and the consequences of connecting a € 900 device to a € 20 battery can be disastrous, leading to irreparable damage to iPhone and leaving this type of damage outside the warranty that Apple offers.

With the Xiaomi PowerBank this aspect is fully guaranteed, and it includes nothing more and nothing less than nine layers of security that guarantee the correct functioning of the battery and an excellent protection of any device connected to it, in this way we make sure that we do not cause any damage to our expensive devices.

Integrated

Xiaomi batteries are usually covered with a metal plate to give that feeling of quality that always accompanies this brand (a feeling that honors its products), however this product is the exception, and given the capacity they have tried to reduce the size and weight of this battery to its minimum expression, thereby preserving an attractive and neat design and more than enough resistance to protect a product like this.

Its casing is made of ecological plastic resistant to shocks, scratches and heat, thus preventing an external heat source from damaging the battery, and as if this were not enough, it consists of its two faces (upper and lower) in relief, small plastic dots give it a touch of originality to this product and prevent it from slipping easily, all this allows this product to weigh only 338 grams, thus being easy to transport and making it the perfect product for any user.

As icing on the cake it has three ports, two of them USB-A and one MicroUSB OTG, the latter located in the center of its front and used to charge the internal battery.

Smart charging system

The Xiaomi battery has a smart charging system which automatically adjusts the output power, voltage and amperage based on the device being connected and its needs.

The battery is capable of detecting what kind of device we are charging and what charge values ​​best suit its needs to transmit power as quickly and efficiently as possible, once the device is fully charged. battery shuts off automatically and intelligently (since it has two outputs) to avoid overloading the device, so we should not worry if we leave our phone connected to it overnight, it will disconnect it when the phone has reached its maximum capacity.

In case this has not caught your attention yet, this battery is capable of charging the new MacBook, we just need to take the USB type A to USB type C charging cable and connect the MacBook to the battery when we need it, it will adjust its parameters automatically to safely load our laptop wherever we need it.

Price

The price is perhaps another of its best aspects, and that is its market value is € 30, a very competitive price as this brand is used to offering, the "bad news" is that Xiaomi does not sell officially in Europe, however we can get it in a trusted store that sells this type of imported products, this time I will I have purchased from Gearbest, where I have bought before and they have earned my trust by sending me original products (there are stores that sell unofficial products, you know that China suffers a lot from imitations).
