Slow Charging

Possible Causes and Solutions:

1. If your power bank itself is recharging slowly:
Try using a different adapter rated at 5V/3A or higher and a different charging cable.
Reference: Recharging a 5,000mAh power bank with a 5V/3A adapter takes approximately 1 hour 50 minutes.

2. If your power bank is charging Your Watch Slowly via Wireless Charging:
(1) Ensure that both the watch and the power bank have cooled down to room temperature and try again 
Reference: Using magnetic charging for an hour can charge the Apple Watch Ultra 49mm from 0％ to 67％.

*Note: Due to the built-in battery, heat buildup over time may reduce output power. A slower charging speed compared to the original charger is normal. Thank you for your understanding.

3. If your power bank is charging your phone slowly via a cable:
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.
Reference: Using wired charging for half an hour can charge the iPhone 16 (with a battery capacity of 3561mAh) from about 0% to 50%.
