CHARGING/RECHARGING
Lead-acid batteries require routine maintenance to ensure a full charge and long battery life. All
batteries lose energy from self-discharge over time and more rapidly at higher temperatures.
Therefore, batteries need periodic charging to replace energy lost through self-discharge. When the
unit is not in frequent use, manufacturer recommends the battery be recharged at least every 30 days.
Notes:
This unit is delivered in a partially charged state – you must fully charge it upon purchase and before using it for the first time. Initial
AC charge should be for 24 hours.
Recharging battery after each use will prolong battery life; frequent heavy discharges between recharges and/or overcharging will
reduce battery life. The battery can be recharged using the Built-In 120 Volt AC Charger.
Make sure all other unit functions are turned off during recharging, as this can slow the recharging process.
If the battery is overly discharged and the green LED lights when the charger is plugged in, this indicates the battery is at a high
impedance stage. If this occurs, recharge the unit and leave it charging for a period of 24-48 hours before use.
CAUTION: RISK OF PROPERTY DAMAGE: Failure to keep the battery charged will cause permanent
damage and result in poor jump starting performance.
Charging/Recharging Using the 120 Volt AC Charger and a Standard Household
Extension Cord (not included)
1. Lift the AC adapter cover located on the back of the unit and connect an extension cord to the
unit. Plug the other end of the cord into a standard 120-volt AC wall outlet.
2. Charge until the green Battery Status LED Indicator lights solid or flashes.
3. Disconnect the extension cord and depress the battery status button. If all 3 status lights
illuminate, the unit is fully charged.
JUMP-STARTER
This Jump-Starter is equipped with an Jump-Starter Power Switch. Once the connections are properly
made, turn the switch on to jump-start the vehicle.
1. Turn off vehicle ignition and all accessories (radio, A/C, lights, connected cell phone chargers,
etc.). Place vehicle in "park" and set the emergency brake.
2. Make sure the Jump-Starter Power Switch is turned to off.
3. Remove jumper clamps from clamp tabs. Connect the red clamp first, then the black clamp.
4. Procedure for jump-starting a NEGATIVE GROUNDED SYSTEM (negative battery terminal is
connected to chassis) (MOST COMMON)
4a. Connect positive (+) red clamp to vehicle battery' s positive terminal.
4b. Connect negative (–) black clamp to chassis or a solid, non-moving, metal vehicle component or body part. Never clamp
directly to negative battery terminal or moving part. Refer to the automobile owner' s manual.
5. Procedure for jump-starting POSITIVE GROUND SYSTEMS
Note:
In the rare event that the vehicle to be started has a Positive Grounded System (positive battery terminal is connected to chassis),
replace steps 4a and 4b above with steps 5a and 5b, then proceed to step 6.
5a. Connect negative (–) black clamp to vehicle battery' s negative terminal.
5b. Connect positive (+) red clamp to vehicle chassis or a solid, non-moving, metal vehicle component or body part. Never
clamp directly to Positive battery terminal or moving part. Refer to the automobile owner' s manual.
6. When clamps are connected properly, turn the Jump-Starter Power Switch to ON.
7. Turn ON the ignition and crank the engine in 5-6 second bursts until engine starts.
8. Turn the Jump-Starter Power Switch back to the OFF position.
9. Disconnect the negative (–) engine or chassis clamp first, then disconnect the positive (+) battery
clamp.
WARNING: TO REDUCE THE RISK OF INJURY OR PROPERTY DAMAGE:
• FOLLOW ALL SAFETY INSTRUCTIONS FOUND IN THE "SPECIFIC SAFETY INSTRUCTIONS FOR
JUMP STARTERS" SECTION OF THIS INSTRUCTION MANUAL.

• This power system is to be used ONLY on vehicles with 12-volt DC battery systems.
• Never touch red and black clamps together — this can cause dangerous sparks, power arcing, and/
or explosion.
• After use, turn the Jump-Starter Power Switch off.
CAUTION: TO REDUCE THE RISK OF PROPERTY DAMAGE:
• Vehicles that have on-board computerized systems may be damaged if vehicle battery is jump-
started. Before jump-starting this type of vehicle, read the vehicle manual to confirm that external-
starting assistance is advised.
• Excessive engine cranking can damage the vehicle's starter motor. If the engine fails to start after the
recommended number of attempts, discontinue jump-start procedure and look for other problems
that need to be corrected.
• If the connections to the battery's positive and negative terminals are incorrect, the Reverse Polarity
Indicator will light and the unit will sound a continuous alarm until the clamps are disconnected.
Disconnect clamps and reconnect to battery with correct polarity.
• If vehicle fails to start, turn off the ignition, turn off the Jump-Starter Power Switch, disconnect the
jump-start system's leads and contact a qualified technician to investigate why the engine did not
start.
• Recharge this unit fully after each use.
12 VOLT DC PORTABLE POWER SUPPLY
This portable power source is also for use with all 12 volt DC accessories equipped with a male
accessory outlet plug and are rated up to 5 amps.
1. Lift up the cover of the unit 's 12 volt DC outlet.
2. Insert the 12 volt DC plug from the appliance into the 12 volt accessory outlet on the unit. DO
NOT EXCEED A 5 AMP LOAD.
3. Switch on the appliance and operate as usual.
4. Periodically press the battery power level pushbutton to check battery status. (When all three
battery status LEDs light, it indicates a full battery. Only one red battery status indicator light
indicates that the unit needs to be recharged.)
USB PORT
The USB power port is under the same protective cover as the 12 volt DC outlet on the left hand side
of the front panel (refer to the Features section to locate)..
1. Push the USB power button to turn the USB port on and the USB power indicator will light.
2. Lift up the cover of the USB charging port.
3. Plug the USB-powered device into the USB charging port and operate normally.
4. Periodically check the unit's battery status by pressing the battery power level button. (When all
three battery status LEDs light, it indicates a full battery. Only one red battery status indicator light
indicates that the unit needs to be recharged.)
Notes:
This unit' s USB Power Port does not support data communication. It only provides 5 volts/2,000mA DC power to an external USB-
powered device.
Make sure the USB Power Button is in the off position when the unit is being recharged or stored.
Some household USB-powered electronics will not operate with this unit.
CARE AND MAINTENANCE
All batteries lose energy from self-discharge over time and more rapidly at higher temperatures. When
the unit is not in use, we recommend that the battery is charged at least every 30 days.
Never submerge the unit in water. If the unit gets dirty, gently clean the outer surfaces of the unit with
a soft cloth moistened with a mild solution of water and detergent.
There are no user-replaceable parts. Periodically inspect the condition of adapters, connectors and
wires. Contact manufacturer to replace any components that have become worn or broken.
Battery replacement/disposal
BATTERY REPLACEMENT
The battery should last the service life of the unit. Service life is dependent on a number of factors
including but not limited to the number of recharge cycles, and proper care and maintenance of the
battery by the end user. Contact manufacturer for any information you may need.
