3.2An Explanation of Power Ratings and Battery Life

AC powered products are rated by how much electrical power (in watts) they consume. Portable Power 250’s internalAC inverter is capable of generating a maximum of 250 watts to power AC products plugged into its AC receptacle. As an example, a lamp with a 40 watt bulb can be operated from Portable Power 250 for up to 3 hours when its 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 built-in12-volt fluorescent light draws less than 0.7 amps and will operate up to 23 hours with both bulbs illuminated, or about 46 hours with one bulb illuminated before the internal battery needs recharging. Portable Power 250 can 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 Portable Power 250 will operate before recharging is required.

3.3Operating AC Electrical Products

1.Ensure the internal battery is fully charged. (See Section 8 for details.)

2.Turn the AC inverter switch ON. The switch illuminates to indicates AC power is available at the AC outlet.

3.Plug the AC product you wish to operate into the AC outlet and switch the product ON. Portable Power 250 will operate most devices rated up to 230 watts.

4.In the event of an overload, low battery voltage, or overheating, the AC inverter will automatically shut down. (See Section 5.3 for details.)

5.Fully recharge the internal battery as soon as possible after each use.
