IMPORTANT: This charging method must not be used with
vehicles having abnormally high voltage electrical systems
that operate above 15 volts DC. Do not leave xPower300
permanently connected to the vehicle’s lighter socket or 12-
volt accessory outlet.
CAUTION: While xPower300 is being recharged with the DC
Charging Cable from your vehicle, do not oerate AC products
over 120 watts from the AC inverter at the same time.
Recharging with a Generator’s 12-Volt DC
Power Outlet
Recharging xPower300 from a generator using xPower300’s AC
Charger is possible, but would require extended generator
running time. Since many generators have an auxiliary
regulated 12-volt DC output designed for charging 12-volt
batteries, using this power source will result in much faster
charging. If the generator has a cigarette lighter style socket
for its 12-volt output, follow the connection instructions in
Section 7 - Recharging from Your Vehicle.
Most of xPower300’s capacity will be recharged in about 1 to 3
hours. Level of charge can be verified using xPower300’s
Battery Level Indicator after disconnecting from the charging
source as explained in Section 3 - Battery Level Indicator.
CAUTION: The generator output must be intended for battery
charging. An unregulated output or one that exceeds 15 volts
DC can damage the battery.
Recharging with a Solar Panel
Small unregulated 12-volt solar panels rated to produce a
maximum of 3 amps (or 40 watts) can be used to charge
xPower300 via the Charger Input Socket.
1. You will need a standard 5.5mm OD x 2.5 mm ID “DC Coaxial
(Barrel Type) Connector”.
2. Solder the solar panel’s wire to the “DC Coaxial Connector” as
shown in Figure 3.
