Using The Portable Power - Schumacher Electric SJ2 Owner's Manual

CHARGING THE INTERNAL BATTERY
Charge the internal battery for the
portable power using an extension cord
(not included).
NOTE: Use of an improper extension
cord could result in a risk of fire and
electric shock.
1. To charge, flip the AC connector on
the back of the unit UP and plug in an
18 AWG or larger extension cord.
2. Plug the extension cord into a 120VAC
electrical wall outlet.
3. While the jump starter is charging, the
RED LED will be on. Complete charging
may take up to 72 hours. When the
RED LED turns off, the jump starter is
ready to use.
4. When the internal battery is fully
charged, the charger will automatically
go into maintain mode and maintain
the battery at full charge without
damaging it. When in maintain mode,
the GREEN LED will pulse, as long
as there is an AC cord connected to
the charging port.
5. Charge the jump starter as soon as
possible after use.

5. USING THE PORTABLE POWER

JUMP STARTING A VEHICLE
IMPORTANT: Using the Engine Start
feature 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 portable
power'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 portable power'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.
CHARGING THE INTERNAL BATTERY
WHILE DRIVING
You may also charge the internal battery
while driving, using a male-to-male
charger cable (part number 94500109 –
not included).
IMPORTANT: DO NOT CHARGE
INTERNAL BATTERY FOR MORE THAN
30 MINUTES OR LEAVE THE BATTERY
UNATTENDED. IT COULD EXPLODE,
CAUSING PROPERTY DAMAGE OR
PERSONAL INJURY.
1. Make sure the car is running.
2. Insert one end of the accessory cable
into the 12V DC power outlet.
3. Insert the other end of the accessory
cable into the vehicle's accessory
outlet (lighter socket).
NOTE: The RED LED does not operate
during this method of charging. Using this
method to charge the battery overrides
the maintain mode and the battery can be
overcharged.
4. Monitor the progress of the charge by
pressing the Battery Status button
on the front of the unit. When the
battery is fully charged, disconnect
the accessory cable from the portable
power, then from the lighter socket of
the vehicle.
NOTE: Completely disconnect the charger
cable when the engine is not running.
5. Turn the switch to the ON position.
6. Crank the engine for no more than
8 seconds. If the engine does not start,
wait 2 minutes before cranking again.
7. After the engine starts, turn the switch
to the OFF position and remove the
portable power from the battery.
8. Charge the portable power.
USING THE USB PORT

securely clipped on the storage
holders.
2. Turn the portable power ON.
3. Plug your device into the USB port.
4. Turn on the USB device.
5. When finished using the USB port,
turn the switch to the OFF position.
