8.4 Recharging with a Generator’s 12-Volt DC
Power Outlet
Recharging Portable Power 250 from a generator using the 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 8.3.
Most of Portable Power 250’s capacity will be recharged in
about 1 to 3 hours. The charge level can be verified using
Portable Power 250’s Battery Level Indicator after
disconnecting from the charging source as explained in Section
4.1.
CAUTION: The generator output must be intended for
battery charging. An unregulated output or one that
exceeds 15 volts DC can damage the battery.
8.5 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 Portable
Power 250 via the Charger Input Socket. You will need to
purchase a standard 5.5 mm OD x 2.5 mm ID “DC Coaxial (Barrel
Type) Connector” to mate with the Charger Input Socket.
Connect the solar panel’s positive (red) wire to the coaxial
plug’s inner contact and the solar panel’s negative (black) wire
to the plug’s outer contact. Once the connector is inserted into
the Charger Input Socket and the solar panel is placed in the
sun, Portable Power 250 will charge automatically just as with
the AC Charger. (See Section 8.2.) A 3-amp solar panel will
charge Portable Power 250 in about 8 hours in direct sunlight.
