7.2  CHARGING THE INTERNAL BATTERY

NOTE: Use a 1A USB charger (not included) to recharge the jump 

starter. Using a charger with less than 1A will increase charge time. 

1.  When charging the internal battery, work in a well ventilated area and do not 

restrict the ventilation in any way.

2.  Connect the micro USB end of the charging cable to the micro USB port 

on the end of the unit. Insert the USB end of the cable into the USB port 

on your charger. 

3.  Plug your charger into a live power source. 

4.  The LED will indicate the charge level, as follows:

•  Red LED flashing: 

 50% power

•  Green LED flashing: 

>

 50% power

•  Green LED lit: 100% power

5.  Charging may take 6.5-15.5 hours, depending on the battery level 

and model type.

6.  Recharge the unit after use, and at least every 3 months.

8.  OPERATING INSTRUCTIONS

8.1  JUMP STARTING A VEHICLE ENGINE

NOTE: Use only the provided jump cable.

IMPORTANT: Do not use the jump starter while charging its internal battery.

IMPORTANT: Using the jump starter without a battery installed in the 

vehicle will damage the vehicle’s electrical system.

NOTE: The internal battery must have a charge if at least 50% to 

jump start a vehicle.

1.  Turn the ignition OFF.

2.  Lay the DC cables away from any fan blades, belts, pulleys and other 

moving parts. Make sure all of the vehicle’s electrical devices are turned off.

3.  Plug the battery clamp smart cable into the jump starter’s output socket. 

The green LED on the smart cable should flash.

4.  For a negative-grounded vehicle, connect the POSITIVE (RED) clamp 

from the jump starter to the POSITIVE (POS, P, +) ungrounded post 

of the battery. Connect the NEGATIVE (BLACK) clamp to the vehicle 

chassis or engine block away from the battery. Do not connect the 

clamp to the carburetor, fuel lines or sheet-metal body parts. Connect 

to a heavy gauge metal part of the frame or engine block.

5.  For a positive-grounded vehicle, connect the NEGATIVE (BLACK) 

clamp from the jump starter to the NEGATIVE (NEG, N, -) ungrounded 

post of the battery. Connect the POSITIVE (RED) clamp to the vehicle 

chassis or engine block away from the battery. Do not connect the 

clamp to the carburetor, fuel lines or sheet-metal body parts. Connect to 

a heavy gauge metal part of the frame or engine block.

6.  The smart cable will detect the voltage of the vehicle and jump starter, 

and will make a clicking sound. The green LED on the smart cable 

should light. 

7.  Turn the key to the ACC position.
