Charging with the DC-to-DC Accessory Cable
The XPower Powerpack comes with a DC Charging cable to
allow the unit to be charged from a DC source such as an
automobile, RV, or boat. The DC Charging Input Port is the
DC Socket on the front of the unit. The vehicle to be used for
charging must have a 12 Vdc accessory socket and must be
running in order to charge the unit.
WARNING: Fire and explosion hazard
Do not use this recharging method if your vehicle has abnormally
high voltage electrical systems that operate above 15 Vdc. This
may lead to accumulations of hydrogen, causing exposure to fire
and explosion hazard. This is typically found in marine applications
or on portable generators with DC output.
Important: Although the charge regulation circuitry for the AC
charging method does not operate with the DC-to-DC charging
method, most vehicle voltage regulators will ensure that the
XPower Powerpack is not overcharged.
Important: Disconnect the unit as soon as the battery is fully
charged or if the vehicle’s engine is turned off. Do not leave the
XPower Powerpack permanently connected to the vehicle’s 12 V
accessory outlet.
Note : The green Charging Status light will not illuminate when
the XPower Powerpack is recharged through the DC Charging
Cable.
Note : Battery Charge (%) indicator is only accurate when the
XPower Powerpack has been disconnected from all appliances
and all charging sources for fifteen minutes.
