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.

Questions about this item

Does the 20000mAh pack get hot or noisy during long charging sessions?

It has no fan or moving parts, so it runs silently and stays cool under normal use.

What cable or adapter do I need to recharge the power bank itself at full speed?

Use a USB-C charger that delivers 9V 2A and a USB-C cable; the pack accepts USB-C or Micro-USB input.

Can I keep using my older Micro-USB phone while also charging a newer USB-C device from the same pack?

Yes, the pack provides one USB-C output and two USB-A ports, so both cable types work simultaneously.
