Power outages are a reality that can threaten your productivity and sense of comfort. The new XPower™ PowerSource 400 by Xantrex™ is the perfect backup power solution for the small office and home office market. In a power outage, it will supply up to eight hours of uninterrupted backup power for a small office. With the XPower PowerSource 400, you’ll be able to keep working and stay productive. 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.
