it.
CAUTION
The output of the Duracel1® Powerpack 300 inverter is a non-
sinusoidal modified sine wave, which is different from pure sine
wave utility-supplied electricity. Certain types of load equipment
may be damaged.
Most rechargeable battery-operated equipment uses a
separate charger or transformer that is plugged into an AC
receptacle and produces a low voltage charging output.
Some chargers for rechargeable batteries can be damaged if
connected to the Duracell® Powerpack 300.
Do not use the following with the Duracell® Powerpack 300:
• Small battery-operated appliances like flashlights, razors,
and night lights that can be plugged directly into an AC
receptacle to recharge.
• Some chargers for battery packs used in hand power
tools. These affected chargers display a warning label
stating that dangerous voltages are present at the battery
terminals.
Note: If you are unsure about using your rechargeable appliance
with the Duracel1® Powerpack 300, contact the equipment
manufacturer to determine the rechargeable appliance's
compatibility with the modified sine wave (non-sinusoidal) AC
waveform.
