Power outages are a reality that can threaten your productivity and sense of comfort. The XPower PowerSource 400 is the perfect backup power solution for the small-office and home-office market. During a power outage, it will supply up to eight hours of uninterrupted backup power to devices such as a small TV, a radio, a laptop computer, a desktop and LCD monitor, an inkjet printer, a copier/printer/fax/scanner, an Internet modem, a VoIP phone, a cell phone, or a cordless phone. Until now, backup power products on the market have only been able to provide limited backup power during outages and not extended runtime like the XPower PowerSource 400. With the XPower PowerSource 400, you will be able to keep working and stay productive--and meet those important deadlines. The XPower PowerSource 400 switches to backup power automatically when a power outage occurs. This happens seamlessly so that the electronic devices that are connected to it won’t sense the power outage. They’ll operate off the XPower PowerSource 400’s charged battery for hours. When grid power returns, the XPower PowerSource 400 switches the devices back to utility power, recharges its internal battery, and enters a standby mode until the next outage occurs.
