Miady AS-TPB22 20000mAh power bank 22.5W

Compact 20000mAh power bank for travellers

The Miady AS-TPB22 is a lithium-ion power bank with a 20000mAh capacity and 22.5W maximum USB-C output. It suits travellers and commuters who need multiple phone charges without access to mains power. Two USB-A ports and one USB-C port allow three devices to charge simultaneously. Four LEDs show remaining capacity in 25% steps.

Sustained output and recharge behaviour

The pack delivers up to 22.5W from its USB-C port and 2.1A from each USB-A port under continuous load. Recharging the bank itself takes about six hours at 9V 2A via USB-C or Micro-USB input. The supplier notes that charging other devices while the bank recharges is not supported, as this would reduce the unit's lifespan.

Upgrade from smaller single-port banks

This model replaces lower-capacity packs that only offer a single USB-A output and slower recharge speeds. The jump is worthwhile when you regularly carry a phone, tablet and earbuds, or when you need a full day of power for multiple devices on trips. It is not for users who require pass-through charging or wireless charging.
