The Portawattz PowerPAC is lightweight, portable backup power system providing up to 300 watts of 115 VAC (household type) power and/or 12 Volts DC at up to 12 amps. It includes an 18 amp-hour sealed lead acid battery and a modified sine wave AC inverter. It weights 18 lbs and measures 6" x 9.4" x 12.5". It has a high power DC connector to allow you to jump start your car. The battery can be recharged using the AC charger, you can charge it from your vehicle as you drive or from a generator equipped with a 12 volt battery charging outlet. A unregulated 12 volt PV solar panel can also be used to recharge the battery. As an example, a 3 amp panel will charge the PowerPAC in about 8 hours of direct sunlight.
By connecting the PowerPAC to a larger, external battery you can get extended operating times. As an example, if connected to a 60 amp-hour battery you achieve about 4 times the operating time of the PowerPAC's internal battery.
The AC outlet can be used to power lights, TVs (up to 27"), VCRs, portable stereos, clock radios, laptop computers, printers, cell phones, power drills, camcorders, portable coolers, electronic cash registers, CD players, electric fans, electric shavers, curling irons, short wave radios, soldering irons, and much more (run times vary depending of the load).
