Operating AC Appliances

High Surge Appliances
The wattage rating of AC appliances is the average power 
used by the appliance. Appliances such as televisions and 
appliances with motors consume much more power than their 
average rating when they are first switched on.
Although the Duracell® Powerpack can supply momentary 
surge power up to 480 W, some appliances may exceed the 
capabilities of the Duracell® Powerpack and trigger the 
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 Duracell® Powerpack’s inverter is a non-
sinusoidal modified sine wave. Some equipment may be damaged 
by the Duracell® Powerpack’s inverter modified sine wave (non-
sinusoidal) output.
Note
: If you are unsure about powering any device with the 
inverter, contact the manufacturer of the device.
