10. Some issues regarding E18's charging problem.
A: 1. It is normal to find the unit slightly hot when being charged or when being usedas a power bank due to the high charging / discharging current.
2. If a charger with insufficient current is used, the charge indicator light would die out after 15s (or just stop blinking); please use a charger with more current capacity.
3. The charging indicator lights would blink continuously when charging, with the
three levels of light to show the battery capacity until all lights stay on steadily
when the unit is fully-charged.
4. The power bank function can’t be used when the device itself is charging.
5. Please do not use the power bank function in case of low battery capacity.
