High Surge Appliances

The wattage rating of AC appliances is the average power

used by the appliance. Appliances such as televisions,

computer monitors and appliances with motors consume

much more power than their average rating when they are

first switched on.

Although XPower Powerpack can supply momentary surge

power up to 600 W, some appliances may exceed the

capabilities of the XPower Powerpack and trigger the

inverter’s safety overload shutdown circuit.

Trouble Appliances

Some appliances, 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 appliances, and other loads may be damaged.

• Some chargers for small rechargeable batteries can be

damaged. See “Precautions for Using Rechargeable

Appliances” on page viii for details.

• Metal halide arc (MHI) lights can be damaged.

CAUTION

The output of the Powerpack’s inverter is non-sinusoidal.

Some equipment may be damaged by the inverter’s modified

sine wave output (non-sinusoidal).

Note: If you are unsure about powering any device with the

inverter, contact the manufacturer of the device.
