CHARGING
This product is partially charged from the manufacturer. Fully charge the unit
immediately after purchase. In order to prolong the internal battery life, be
sure to fully recharge the unit after each jumpstarting, or every month even
if this unit has not been used. In addition, we recommend not to charge and
discharge the unit at the same time.
To check the internal battery’s charge status, press the Battery Voltage
and % Indicator button (the screen will turn off in 10 seconds). Charge the
internal battery if the display shows it is under 100%.
NOTE:
The internal battery’s percent of charge is most accurate when the
jump starter has been disconnected from all devices and charging sources
for a few hours.
AC Charging (Recommended):
DC Charging in Your Vehicle:
1. Insert AC charging adapter into charging jack of the unit.
2. Plug the other end of AC charging adapter into a wall socket.
1. Turn the vehicle engine on.
2. Insert one end of the accessory cable into the 12V DC power outlet.
3. Insert the other end of the accessory cable into the vehicle’s accessory
outlet (lighter socket).
4. Turn on the Jump Start + 12V DC Power On/Off Switch.
You may also charge the internal battery while driving, using a male-to-male
(insertion plug at each end) charger cable.
NOTES:
Using DC charging method to charge the battery overrides the
maintain mode and the battery can be overcharged. Monitor the progress of
the charge by pressing the Battery Voltage and % Indicator button and do
disconnect immediately after battery is fully charged. Completely disconnect
the charger cable when the engine is not running.
