5. 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. The
Battery Status LEDs will light for 30 seconds
and then turn off. While the Battery Status
LEDs are off and the ON/OFF Power switch
is on, press the Battery Status/Light
button on the front of the unit. The LEDs will
indicate the current charge level as follows:
RED – less than 20% of full charge;
immediately charge the unit.
YELLOW – 20-80% of full charge.
GREEN – more than 80% 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.

6. USING THE JUMP STARTER

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 the
on the jump starter. The green Ready
LED will light.

your charger's USB port.
2. Plug your charger into a live power
source.
3. When the unit is charging, the LEDs
above the Battery Status/Light
button will light to show the charging
percentage as follows:
Red LED flashing: 0-5% charged
Red LED solid: 6-19% charged
Yellow LED solid: 20-80% charged
Green LED solid: 81-100% charged
4. Ten seconds after the battery has
reached full charge, the green LED
will change from solid to pulsing.
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.
