According to Xiaomi, this battery has a real output capacity of 6,900 mAh, which is equivalent to two full charges of your phone.
It is very fast and efficient, so much so that the Mi Power Bank adapts its power up to 18 W.
Note that in the box is included a USB Type-C adapter.

The Aukey USB-C 10000mAh mobile battery can charge any device via its supplied micro USB to USB-A cable, but for your smartphone or Nintendo Switch with USB C output, you will need your own cable.
It features Charge Adaptive AiPower technology to provide the amount of energy your devices need. Thanks to its green LEDs keep an eye on its remaining power.

Anker PowerCore 10000 QC
Fast, light and affordable, this external battery stores 10000mAh and allows quick recharging of “quick charge 3.0” phones. The Anker PowerCore 10000mAh notably won us over with its excellent quality/price ratio. It is the ideal companion for all your trips.
Tronsmart Trim 10000mAh
Another manufacturer of external batteries with excellent value for money is Tronsmart.
The Trim 10000mAh is fitted with a micro-USB / USB-A cable for easy recharging, as well as for your devices. Note that the USB A port is also capable of providing 18W to compatible devices. What we regret is that it lacks a USB Type-C cable to take advantage of its 18W Power Delivery port …
The Tronsmart Trim has a very nice design, rectangular and thin (144 x 70 x 12 mm and weighs 194 g). The black case has a matte finish that holds well in the hand and does not slip, its edges are metal, gold or pink colors.
We love this RavPower battery because it’s a compact portable 10,000mAh battery that quickly charges up to two devices.
Do not be fooled by the 29W indicated because it is the maximum power of the 2 combined ports. It is enough to recharge 2 or even 4 times a smartphone, depending on your device.
This RavPower has two USB outputs: a Quick Charge port and a USB-C port which can provide 18 W input and output.
Moreover, using this port, the RavPower is full in just 3 hours. Also, we like the fact that it charges simultaneously with the connected device.
The Iceworks 7000 we tested is a USB Type-C model, which can only be used with Android smartphones, it excludes iPhone users.
It is a fast charger with an input and output capacity of 15W. Its USB Type-C input is also an output, so you can charge two devices at the same time if needed.
We like the idea that the cable is built into it.
It fits well in the hand, at its end you will find the different USB outputs, finally on the side 4 LEDs and a button allowing you to check the remaining energy level.
Aukey 20000mAh USB-C Battery
The battery 20000 mAh Aukey is attractive for three reasons: its price, its large capacity, the number, and variety of ports.
It incorporates 3 USB outputs and a USB-C port. The latter can be used to charge the Aukey.
While the USB-C has a speed of up to 3A (15W), the other three outputs must share the same amount with each other. So if you plug in three devices, they will each charge at a slow rate of 5W.
Once exhausted, the Aukey will require 10 hours to refuel, although you can continue to charge connected devices.
The compromise for all this power is the size and this Aukey battery is huge. It is much larger than some phones, but it has the advantage of being slim (14 mm). However, this tapered side stops there because it still weighs 435 g …
It’s 4 small LEDs on the side indicate the remaining power.
Flux Load Plus
We have included the Flux Charger Plus mobile battery as it is a great all-in-one product. It includes all the cables and outputs necessary to charge your smartphone (iOS / Android) while remaining thin and ultra-portable (13.6 x 7.1 x 1 cm, 200 g) and powerful (10,000 mAh).
Like almost all backup batteries on the market, it has LEDs indicating the amount of energy remaining.
How To Choose Your Portable Battery?
Choosing the right portable battery depends on your needs and your devices. The key is to find the balance between portability, cost, number of recharges and speed of recharging.
Some will prefer a portable battery that fits easily in a bag and that offers two full recharges of their mobile phone, others will choose a larger battery that has under the hood, and that can charge several devices at the same time.
