The Home-Office Uninterruptible Power Supply

This emergency power source connects to an AC outlet and seamlessly switches to backup power during a blackout, ensuring up to eight hours of uninterrupted power for five devices, such as a personal computer, printer, or laptop, and automatically returns to utility power once the grid is restored. Unlike common backup power units that are only capable of supporting one electronic appliance for minimal time periods, this portable power supply outputs 400 watts and provides up to eight hours of back-up time for your computer, cordless telephone, and printer. A digital LED display indicates battery capacity and the total wattage of the connected devices, while an automated LED illuminates five 115 VAC outlets, ensuring accessibility in the dark. The power source has a surge protection capacity of 640 watts and an internal temperature monitor prevents over heating. The sealed, non-spillable 40 amp-hour AGM battery can achieve between 250 and 300 complete discharge/recharge cycles before it needs to be recycled. An alarm signals ten minutes before the power supply is empty and the unit requires 8 hours to fully recharge from a 50% discharge level and 20 hours when the battery is empty. 10 3/4" H x 3 3/4" W x 18 1/2" L.
