    Panel  information                     

 1.AC charging ports:  Charge the device with city home power.

 2.Battery indicator: Red light means the power unit is charging, and green light means that’s fully charged.

 3. USB5V output ports: Support power with 5V2A.

 4. Smart Display: Show the remaining battery capacity with precise percentage.And the battery volume won’t change when voltage is fluctuating. You can see the real load power during charging and discharging as well as the remaining working hours. When charging, you could see how many hours to fully charge the device; And when discharging, the hours you see means the left working hours. After several years of long-term working  for the power pack, if the remaining battery capacity shows XX%, but there is a low voltage alarm, it means the battery volume is attenuating and there is a self-loss for the battery.
