According to Maplin

A full recharge of this UPS takes approximately 8 hours and provides 660W at 1100VA of emergency power for connected devices. The maximum runtime of this UPS is dependent of the load being drawn at any one time. For example, a single connected computer system drawing 200w of power will continue to run for an estimated 22 minutes after a loss of power on this UPS – enough to save your files and shut down safely.
