2. PERSONAL SAFETY PRECAUTIONS
2.1 Wear complete eye protection and protective clothing when working near lead-
acid batteries. Always have someone nearby for help.

medical attention.
2.4 Neutralize any acid spills thoroughly with baking soda before attempting to
clean up.
2.5 Remove all personal metal items from your body, such as rings, bracelets,
necklaces and watches. A battery can produce a short circuit current high
enough to weld a ring to metal, causing a severe burn.
2.6 Never smoke or allow a spark or ame in the vicinity of the battery or engine.
2.7 This product contains a lithium ion battery. In case of re, you may use
water, a foam extinguisher, Halon, CO
2
, ABC dry chemical, powdered graphite,
copper powder or soda (sodium carbonate) to extinguish the re. Once the
re is extinguished, douse the product with water, an aqueous-based
extinguishing agent, or other nonalcoholic liquids to cool the product and
prevent the battery from re-igniting. NEVER attempt to pick up or move a hot,
smoking, or burning product, as you may be injured.

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.
5.1 CHECKING THE LEVEL OF THE INTERNAL BATTERY
Press the
Light/USB Power button on the front of the unit. The LEDs will indicate
the current charge level as follows:
Charge the internal battery if the LEDs indicate less than 75%.
5.2 CHARGING THE INTERNAL BATTERY
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
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 AC or DC power outlet.
3. Approximate time to fully charge the jump starter (with 2A charger): 5-6 hours.
When the unit is fully charged, all four white LEDs turn solid for a short time, and
then shut off.
4. When the battery is fully charged, disconnect your charger from the outlet and
then remove the charging cable from the charger and the unit.
5. Charge the unit as soon as possible after use.
5.3 CHARGING THE INTERNAL BATTERY WHILE DRIVING
You may also charge the internal batteries while driving, using the 12V DC car
charger (included).
1. Make sure the car is running.
2. Plug the 12V DC adaptor cable into the unit’s 12V input socket.
3. Insert the other end of the accessory cable into the vehicle’s accessory outlet.
4. Approximate time to fully charge the jump starter: 3 hours.
When the unit is fully charged, all four white LEDs turn solid for a short time, and
then shut off.
5. 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.
6. Charge the unit as soon as possible after use.
NOTE: Completely disconnect the charger cable when the engine is not running.
6. OPERATING INSTRUCTIONS
6.1 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.
NOTE: Make sure all of the vehicle’s electrical devices are turned off.
•••• 100% charged
••• 75% charged
•• 50% charged
• 25% charged
• 9 •
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
batter y.
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
Jump start button 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 a gain.
7. After the engine starts, press the
Jump start button 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. NOTE: Recharge the unit
when all Battery Status LEDs are off.
6.2 STARTING A BATTERY WITH LOW VOLTAGE
If the vehicle’s battery voltage is too low for the jump starter to detect that the
clamps are connected, there is a manual start procedure to enable the jump start
function.
1. Make sure the clamps are correctly connected.
2. Press the
Jump start button. Next, press the Jump start and the Light/
USB Power buttons. Hold both for 5 seconds to turn on the override mode. The
green Ready LED will ash.
This overrides a safety feature. It will energize the clamps and cause
sparking if they are touched together. If the clamp connections are shorted or
reversed, damage to the unit, battery and possibly the car’s electrical system will
occur.
6.3 USING THE USB PORT
The USB port provides up to 2.4A at 5V DC.
1. Ensure the battery clamps are securely clipped on the storage holders.
2. Press the
Light/USB Power button on the front of the unit to turn on the power.
3. Plug your device into the USB port.
4. Turn on the USB device, if necessary.
5. When nished using the USB port, turn off the device (if necessary) and unplug the
device.
6. Recharge the unit as soon as possible after each use. NOTE: Recharge the unit
when all Battery Status LEDs are off.
6.4 USING THE WORK LIGHT
1. Position the jump starter on a at, stable surface near the intended work area.
2. Ensure the battery clamps are securely clipped on the storage holders.
3. Hold the
Light/USB Power button on the front of the unit for 0.75 second, to
cycle through the following modes:
• Steady glow
