Xiaomi Mi Power Bank 3 Pro Review
Xiaomi Mi Power Bank 3 Pro 20000mAh 45W power bank with USB-C PD input/output and dual USB-A ports, 74Wh lithium-polymer cell.
The higher-capacity member of Xiaomi's Mi Power Bank 3 line, packing 20,000mAh (74Wh) into a single USB-C PD port capable of 45W plus two auxiliary USB-A ports for charging multiple devices at once. A 45W charger refills it in about 4.5 hours.
Charging speed
45W USB-C PD output is enough to trickle-charge some ultrabooks and fast-charge most phones and tablets, though it falls short of full-speed laptop charging.
