An Explanation of Power Ratings and Battery Life
AC powered products are rated by how much electrical power
(in watts) they consume. xPower300’s AC inverter is capable
of generating a maximum of 300 watts to power AC products
plugged into the AC receptacles. As an example, a 40 watt
light bulb can be operated from xPower300 for up to 3½ hours
when xPower300’s internal battery is fully charged.
12-volt DC auto and marine accessories are generally rated
according to how much electrical current (in amperes or
“amps”) they draw from the battery. The small 12-volt
fluorescent light included draws less than 0.7 amps. When
connected to the xPower300’s DC Power Socket, this light
could be expected to operate up to 25 hours with its switch set
to “II”, or about 50 hours with its switch set to “I” before
xPower300’s battery needs recharging. xPower300 is designed
to supply up to 12 amps from its DC Power Socket.
Remember: The fewer watts an AC product uses, or the fewer
amps a DC accessory draws, the longer xPower300 will operate
before recharging is required.
Operating 115-Volt AC Products
1. Ensure xPower300 battery is fully charged. See Section 7 for
details.
2. Turn the AC inverter switch ON. The green POWER light
indicates AC power is available at the AC outlets.
3. Plug the AC product(s) you wish to operate into the AC outlet(s)
and switch the product(s) ON, one at a time. xPower300 will
operate most devices rated up to 300 watts.
4. In the event of an overload, low battery voltage, or overheating,
the AC inverter will automatically shut down and its red FAULT
light will illuminate. See Section 4 - Automatic Protection
Overload, Overheating and Low Battery for details.
5. Fully recharge xPower300’s battery as soon as possible after
each use.
