Description

This Xiaomi Power Bank 20000mAh (Integrated Cable) is engineered to give you a reliable high-capacity power source wherever you go. Internally it uses two 10,000 mAh battery cells (3.7 V nominal) delivering 74 Wh of energy - which meets aviation-friendly limits. The built-in USB-C cable eliminates the need for carrying separate leads, while the additional USB-C and USB-A ports enable simultaneous charging of multiple devices. Output is intelligently managed thanks to an onboard chip that recognises connected devices and adjusts current accordingly.

The device is rated for 22.5 W max output when charging a compatible device via a single port, and supports two-way fast charging so the power bank itself can be replenished more quickly than standard models. Safety has also been strongly addressed: over-voltage, over-current, short-circuit, temperature and over-discharge protections are all included. The matte dark grey finish gives a premium feel and the compact size (128 x 73 x 32 mm) means it fits easily into a bag or backpack for daily carry or travel use.

FAQ

How many times can this power bank charge my smartphone?

Depending on your device's battery capacity and charging efficiency, this 20,000 mAh power bank can typically charge a modern smartphone 3-5 times; for example, a 4,000 mAh phone may get 4+ full charges.

Is the built-in cable compatible with iPhones or just USB-C devices?

The integrated cable is USB-C which directly works with USB-C devices. For iPhones (Lightning) or older micro-USB devices you will still need the appropriate adapter or cable; other ports (USB-A or USB-C) on the power bank can be used with your own cable.

Can I charge multiple devices at the same time?

Yes. The power bank supports connecting up to three devices simultaneously via its USB-A port, USB-C port and built-in USB-C cable. Just be aware that when multiple devices draw power at once, the per-port output may reduce in order to manage total load.

Is it allowed on a plane?

Yes. With a capacity of 74 Wh (below the typical airline carry-on limit of 100 Wh for batteries), this power bank meets travel-friendly standards-though you should always confirm with your airline.

Does it support fast charging and how long does it take to recharge the power bank itself?

It supports up to 22.5 W output for device charging, and its input supports fast charging (e.g., around 9 V 2.5 A) so the unit can recharge in approximately 5.5 hours under optimal conditions.
