Xiaomi Mi Power Bank 3 unveiled with 30,000 mAh capacity, 18 W output and 24 W input

Xiaomi unveiled its largest power bank yet, the Mi Power Bank 3 with 30,000mAh capacity. That’s enough to charge a phone like the Xiaomi Mi 10 (4,780 mAh) 4.5 times or something smaller like the new iPhone SE (1,821 mAh) over 10 times.

The bank has two full-size USB-A ports, one USB-C and one microUSB. You can get 18W output from the USB-A and USB-C ports. The battery also has a low-current mode for small gadgets (e.g. smartwatches or Bluetooth earbuds) which have trouble charging from some power banks – this mode can be accessed by tapping the power button twice.

The Xiaomi Mi Power Bank 3 itself can be charged at up to 24W using its USB-C port. If you have a 30W Xiaomi fast charger, for example, the battery can be filled to 100% in 7.5 hours. The microUSB input is limited to 18W.

The external battery will be sold on JD.com in China, starting on June 18. The price is CNY 170 ($24/€21).
