4. CHARGING THE INTERNAL BATTERY OF THE JUMP STARTER
IMPORTANT: CHARGE IMMEDIATELY AFTER PURCHASE, AFTER EACH USE AND EVERY 30 DAYS, TO
KEEP THE JUMP STARTER’S INTERNAL BATTERY FULLY CHARGED AND PROLONG BATTERY LIFE.
4.1 CHECKING THE LEVEL OF THE INTERNAL BATTERY
Press the ON/OFF Power switch, and then press the Battery Status/Light button on the front of the unit. The LEDs
will indicate the current charge level as follows:
Red LED flashing: 0-5% of full charge; immediately charge the unit.
Red LED solid: 6-49% of full charge.
Yellow LED solid: 50-75% of full charge.
Green LED solid: 76-100% of full charge.
4.2 CHARGING THE INTERNAL BATTERY
The jump starter will fully charge in 3-4 hours.
NOTE: Use a 2A USB charger (not included), or a 2A USB charging port to quickly recharge the jump starter. Using
a charger with less than 2A will increase charge time.
1. Plug the Micro USB end of a charging cable into the input port. Next, plug the USB end of the charging cable into
your charger’s USB port.
2. Plug your charger into a live power source.
3. When the unit is charging, the three LEDs will flash as follows:
Red LED flashing: 0-49%
Red LED solid and Yellow LED flashing: 50-75%
Red and Yellow LEDs solid and Green LED flashing: 76-99%
Green LED solid: 100%
4. Ten seconds after the battery has reached full charge, the green LED will turn solid.
5. If the Red Ready/Fail LED lights and the buzzer sounds, the unit’s protection has been activated (such as short
circuit protection, battery low voltage protection, reverse polarity protection, etc.) and the unit will not operate.
6. When the battery is fully charged, disconnect your charger from the power source and then remove the charging
cable from the charger and the unit. Make sure the power switch is set to OFF, if not using the jump starter
immediately.
5. OPERATING INSTRUCTIONS
5.1 JUMP STARTING A VEHICLE
IMPORTANT: Using the jump starter without a battery installed in the vehicle will damage the vehicle’s electrical
system.
1. Turn the ignition OFF.
2. Lay the DC cables away from any fan blades, belts, pulleys and other moving parts.
3. For a negative-ground vehicle (as in most vehicles), connect the jump starter’s POSITIVE (RED) clamp to the
POSITIVE (POS, P, +) battery post. Next, connect the NEGATIVE (BLACK) clamp to the vehicle chassis or engine
block, away from the battery.
4. For a positive-ground vehicle, connect the jump starter’s NEGATIVE (BLACK) clamp to the NEGATIVE (NEG, N, -)
battery post. Next, connect the POSITIVE (RED) clamp to the vehicle chassis or engine block away from the
battery.
5. Press the ON/OFF switch to turn on the jump starter. The green Ready LED will light.
6. It is best to wait 30 seconds after clamp connection to attempt to start the vehicle. Crank for up to 5 seconds. If
engine does not start, wait 30 seconds before cranking again.
7. After the engine starts, press the ON/OFF switch to turn the jump starter off, and then disconnect the black clamp (-
) and the red clamp (+), in that order.
8. Recharge the unit as soon as possible after each use.
