The Xiaomi Ultra Slim 4900mAh 20W Power Bank is the slimmest and lightest power bank Xiaomi makes, at 113 x 53 x 10 mm and 93 g. It is built for a quick top-up during the day, and it slips into a shirt pocket, a wallet or a small bag.

A single USB Type-C port works in both directions. It charges phones, tablets, earbuds, neckbands, trimmers and PS4 or PS5 controllers at up to 20W, and supports PD 2.0, PD 3.0, PPS, QC 2.0, QC 3.0, QC 3.5, AFC and FCP. Recharging takes about 1 hour 32 minutes with a 33W charger and the included cable. Xiaomi builds in 12 layers of protection, covering temperature, short circuits, over-voltage, over-current and overcharging.

The 4900mAh lithium-ion cell has a rated output capacity of 2700mAh at 5V/2.4A, which is what reaches your device after voltage conversion. With one port it charges one device at a time, and no wall charger is included. Xiaomi advises against charging it inside the carry pouch or leaving it in direct sunlight.

Charge the power bank fully before first use with the included USB cable and a USB Type-C charger, sold separately. To charge your phone or earbuds, connect them to the same USB Type-C port. Take it out of the pouch while charging and keep it away from direct sunlight and heat.
