Problem Cause Solution
The power pack can not jump
start vehicle
The battery in the power pack
is not fully charged
Charge it for at 23 hours
The engine start capacity
exceeds the power pack jump
start capacity.
The power pack’s battery has
been damaged
Replace the power pack’s
battery (consult service
technician).
The charging status LED
indicator does not light.
No AC power at the AC wall
outlet.
Ensure power is available at the
AC wall outlet.
AC charging adapter is faulty. Replace 120V AC charger
The charging status LED
indicator still lights red and has
not charged to steady after 50
hours of charging.
The AC charger’s output is too
low.
Replace the AC charger
The AC appliance does not
operate; audible alarm is not
sounding.
AC appliance rated more than
80W, the safety overload has
tripped.
Use AC appliance with a power
rating less than 80W.
AC appliance rated less than
80W, high starting surge has
tripped the safety overload.
AC appliance may exceed the
power pack’s surge capability.
Use an AC appliance with a
starting surge within the power
pack surge rating.
Battery has discharged to 10V Recharge the battery.
Inverter has overheated due to
poor ventilation or excessively
warm environmental condition.
Allow the power pack to cool for
15 minutes or more. Clear
blocked fan opening or remove
objects covering the unit, then
restart the power pack. Move to
a cooler environment.
Run time for appliance is less
than expected.
Internal battery is not fully
charged,
Recharge using the AC charger,
until the charging status LED
indicator light green.
AC appliance power
consumption is higher than
expected.
Check AC appliance power or
wattage rating (or current draw
for 12V DC appliance).
Troubleshooting
Buzzing in audio systems and radios
Some inexpensive stereo systems and AM-FM radios have inadequate internal
power supply filtering and “buzz” slightly when powered by the power pack.
Generally, the only solution is an audio product with a higher quality filter.
Television interference
The power pack is shielded to minimize its interference with TV signals.
However, with weak TV signals interference may be visible in the form of lines
scrolling across the screen. The following should minimize or eliminate the
problem:
• Increase the distance between the inverter and the TV, antenna and cables.
• Adjust the orientation of the inverter television, antenna and cables.
• Maximize TV signal strength by using a better antenna and use shielded
antenna cable where possible.
WARNING: Electric shock hazard
Do not remove the cover of the unit or disassemble. The unit does not contain
any internal user-serviceable parts and attempting to service the unit yourself
could result in electrical shock or burn.
