What should I do if my power bank isn't charging my device?

Try using a different device, cable, plug, and wall outlet to identify the issue. If it still doesn't charge, further assistance may be needed.

Why won't my power bank fully recharge, and how can I fix it?

It could be software or hardware voltage detection issues. To troubleshoot, try discharging the power bank completely, then recharge. If it still doesn't recharge fully, additional support might be required.
