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.
Typical 12 Vdc appliances that can be used on the XPower
Powerpack are listed in Table 3-2.
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 O
N /O FF switch to ON when using the
XPower Powerpack to operate a 12 Vdc appliance.
Having the AC Outlet O N /O FF 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.
