Problem appliances
The output of the power pack inverter is non-sinusoidal. Some equipment may
be damaged by the inverter’s modified sine wave output (non-sinusoidal).
Some appliance, including the types listed below, may be damaged if they are
connected to the inverter.
• Electronics that modulate RF (radio frequency) signals on the AC line will
not work and may be damaged.
• Speed controllers found in some fans, power tools, kitchen appliance, and
other loads may be damaged.
• Some chargers for small rechargeable batteries can be damaged.
• Metal halide arc (MHI) lights can be damaged.
Note: If you are unsure about powering any device with the power pack,
contact the manufacturer of the device to determine whether it is compatible
with the modified sine wave output.
12V DC appliances
The power pack can operate one 12V DC auto, RV, marine, or other portable DC
appliance that draws 10 amps or less from its DC socket. The combined load
must not exceed 120 W, The less combined wattage used, the longer the power
pack will operate before recharging is required.
Operating DC appliances:
1. Check battery status to ensure the battery is fully charged.
2. Open the DC socket.
3. Plug the DC appliance into the DC socket.
4. Turn the DC appliance ON.
5. Recharge the power pack immediately after use.
USB Devices
The power pack can charge or power one USB-chargeable device through its
USB port. Compatible devices include most MP3 players, PDAs, digital
cameras, and camcorders that have internal batteries which can be charged
via the USB port of a desktop/laptop computer.
USB-chargeable devices usually include a special USB cable (not supplied)
that attaches one end to the USB port and the other end to the device.
Using the Air Compressor
Warning: Fire Hazard
The compressor is designed for short-term operation only. Operating the
compressor over an extended period of time will cause the compressor unit
to overheat, which could lead to fire. Allow the compressor to cool down for
10 minutes after each 10 minutes of continuous operations.
Warning: Fire Hazard
Do not leave the compressor unattended while in operation. Keep out of
reach of children.
Warning: Risk of personal injury or damage of equipment
Do not exceed the recommended pressure of either the compressor or the
object being inflated. The compressor is capable of inflating to 260 PSI.
If the recommended pressure is exceeded, an explosion may result.
Warning: Risk of personal injury or damage of equipment
If the power pack with air compressor shuts off due to an over-temperature
condition, turn OFF the compressor switch and allow the compressor to cool
for 15 minutes before re-starting. If the power switch is not turned off, the
compressor will automatically turn itself on when it reaches an acceptable
operating temperature. If left unattended, it is possible that the unit can over-
inflate the object being inflated and create an explosion hazard.
Caution: Equipment damage
The power pack with air compressor cannot be used to inflate large capacity
inflatables such as float tubes, large air mattresses, transport truck tires, and
inflatable boats. These types of products require extended inflating times,
which may damage the compressor.
