Slow Charging

Possible Causes and Solutions:

If your power bank itself is recharging slowly:
Try using a different adapter rated at 9V/2A or higher and a different charging cable.
Reference: Recharging a 20,000mAh power bank with a 20W adapter takes approximately 5 hours.

If your power bank is charging your phone slowly:
1) Use a different charging cable or try another output port on the power bank.
2) Check your phone’s fast charging protocol and maximum supported input.

This power bank supports up to 22.5W output, but the actual charging speed also depends on your phone’s maximum input. For example, the iPhone 12 supports up to 20W, so even with a 22.5W power bank, it will only charge at 20W.
For reference, it takes about 1 hour to fully charge an iPhone 12 with this power bank.
