Operation

12 Vdc Appliances

The XPower Powerpack can operate one 12 Vdc auto, RV, marine, or other portable appliance that draws 12 amps or less from a 12 Vdc power outlet or from a vehicle’s accessory socket. The fewer watts a 12 Vdc appliance draws, the longer the XPower Powerpack will operate before recharging is required.

Important: Know the size of the loads.

144 watts DC Maximum Load

Amps x Volts = Watts

12 amps DC x 12 volts DC = 144 watts DC

CAUTION Equipment damage

The DC Power Socket does not automatically switch off when the internal battery is discharged.

To protect the internal battery against damage resulting from total discharge, turn the AC Outlet ON/OFF switch to ON when using the XPower Powerpack to operate a 12 Vdc appliance.

Having the AC Outlet ON/OFF switch turned ON enables the low-battery alarm to warn you when the 12 Vdc appliance has nearly depleted the internal battery. This should allow you adequate time to remove the load and prevent damage to the battery.

Typical 12 Vdc appliances that can be used on the XPower Powerpack are listed in Table 3-2.
