4.8  CHARGING THE INTERNAL BATTERY 

WHILE DRIVING

You may also charge the internal battery 

while driving, using a male-to-male  

charger cable (part number 94500109 –  

not included). 

IMPORTANT: 

DO NOT CHARGE 

INTERNAL BATTERY FOR MORE THAN 

30 MINUTES OR LEAVE THE BATTERY

CAUSING PROPERTY DAMAGE OR 

PERSONAL INJURY. 

1.

Make sure the car is running.

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).

NOTE: 

The

 button on

the front of the unit. When the battery is 

fully charged, disconnect the accessory
