Comprehensive Protection
Automatic overload
The XPower Powerpack has built-in protection against output
overload. If you connect an appliance to the AC Outlet that
draws more than 250 watts, or one which draws excessive
surge power, the power to the AC Outlet automatically shuts
off.
Overheating
The XPower Powerpack is protected from overheating. If the
inverter exceeds a safe temperature, power to the AC Outlet
automatically shuts off.
Low Battery Protection
Low battery protection protects the internal battery from
excessive discharge and possible damage. When the AC
Outlet On/Off switch is turned on, an audible alarm alerts you
when the internal battery is nearly discharged (10.7 volts DC)
and the unit turns off at 10.0 volts DC.
Jump-start Cables Safety Feature and Reverse Polarity Detection
The XPower Powerpack has a special jump-start safety
feature that eliminates the sparking that sometimes occurs
when the jump-start cables are connected to a battery. The
XPower Powerpack can also detect a reverse polarity
connection and notifies you with an audible alarm and a
Battery Clips Connected Improperly (red light).
The battery to be jump-started must have a terminal voltage
of at least 4 volts in order to work with the XPower
Powerpack.
