Xiaomi Mi Power Bank 3 20000mAh Review: USB-C Two-way 45W QC3.0 Fast Charge Power Bank

1

A few days ago, Xiaomi announced that the cumulative sales of Xiaomi power banks exceeded 100 million. With this announcement, the manufacturer released a new power bank, namely the Xiaomi Mi Power Bank 3 20000mAh high version.

Design

There is nothing special with the Xiaomi Mi Power Bank 3 20000mAh high version’s package. The product comes in a simple white box, with some core parameters printed on the surface and a security mark. Currently, Xiaomi Mi Power Bank 3 20000mAh high version is available in black only. The shell uses a one-piece plastic. The upper and lower parts have a high-gloss treatment of ceramic texture. The only disadvantage is that it is easy to leave a fingerprinting when using. However, the Xiaomi Mi Power Bank 3 20000mAh high version is very solid, and it’s not easy to scratch.

This simply means you have no reason to worry about scratches when charging various products, such as smartphones, computers, cameras, etc. We should also take into consideration that this is a large-capacity power bank, which supports fast charging. So it’s quite logical its volume and weight are also considerable. The length, width, and height are 153.5mm, 73.5mm, and 27.5 mm, respectively, and it weighs approximately 440 grams.

Features

The Xiaomi Mi Power Bank 3 20000mAh high version has a capacity of 74Wh (3.7V 20000mAh) and a 5V 5.4A output rated capacity of 12600mAh. Shortly, it can charge a 3000mAh battery of a smartphone 4 times. There are two traditional USB-A female ports and one USB-C port. The USB-A single port can provide 5V/2.4A, 9V/2A, and 12V/1.5A output power. The dual-port can work at the same time to provide a 5V/3A output, which is suitable for fast charging of smartphones supporting Qualcomm QC. More interestingly, the Xiaomi Mi Power Bank 3 20000mAh high version sports the strongest middle USB-C port. This port supports the PD protocol as well as 5V 3A, 9V 3A, 12V 3A, 15V 3A, 20 V2A five gears and a maximum output of 45W. This means that it can not only quickly charge the iPhone (the last two generations), Xiaomi Mi 8, Huawei Mate 20, Smartisan Nut R1 and other PD-compatible smartphones but also the Nintendo Switch, Canon EOS R and other devices. It can quickly charge up most USB-C laptops without losing a lot of power adapter’s 45W power.

In addition, the Xiaomi Mi Power Bank 3 20000mAh high version’s USB-C port also supports up to 45W (15V 3A or 20V 2.25A) input. So you can use 45W or higher adapters (such as MacBook or Xiaomi laptop adapters) to quickly charge it. Xiaomi’s official data is that it takes 4.5 hours when using the 45W adapter to fill the power bank fully. We have had a faster experience, and it was almost full in three hours. It is currently available on BANGGOOD for $45.99. Please note that this price is only available for just 100 pieces, and after that, the price would increase. So do well to get one before the offer gets exhausted.
