Do not use the jump starter while charging the internal battery.
You may also charge the internal battery while driving, using a male-to-male charger
cable (part number 94500109 – not included). Insert one end of the accessory cable into
the 12V DC power outlet and the other end into the vehicle’s accessory outlet (lighter
socket). Completely disconnect the charger cable when the engine is not running.
Using this method to charge the battery overrides the maintain mode
and the battery can be overcharged. Monitor the progress of the battery and when it
reaches a full (100%) charge, disconnect the charger. Do not charge it for more than
four hours or leave the battery unattended. It could explode, causing property damage
or personal injury.
