High-capacity portable charging

The Aluratek ASPB20KF is a 20000 mAh power bank with dual USB outputs. It supports Qualcomm Quick Charge 3.0 at 5V/3A, 9V/2A and 12V/1.5A alongside a standard 5V/2.4A port. The unit recharges in 3 hours via a 5V/2.1A input. LED indicators show remaining capacity.

Travellers and multi-device users

This power bank suits anyone who needs to charge two USB devices at once while away from mains power. Quick Charge 3.0 compatibility benefits phones that support the standard. Buyers whose devices only charge via USB-C Power Delivery or proprietary fast-charging protocols will not gain the speed advantage.

Quick Charge 3.0 output voltage

The single specification that decides fit is the Quick Charge 3.0 output profile of 5V/3A, 9V/2A and 12V/1.5A. If your phone or tablet negotiates one of these voltage steps, you will see the advertised 4× speed increase over 5V/1A charging. Without QC 3.0 support, the bank still delivers 5V/2.4A but not the accelerated rates.

Questions about this item

How do I charge this power bank and what mistake should I avoid?

Use the 5V/2.1A input port; a slower charger will extend the 8-hour recharge time.

What part will need replacement first?

The built-in lithium-ion battery degrades after hundreds of cycles and cannot be user-replaced.

Which output limit appears first during heavy use?

The Quick Charge 3.0 port drops from 12V/1.5A to lower voltages as the 20000 mAh capacity drains.
