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.

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.

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.
