“Do the USB Charge / power ports stay energized with loss of utility AC power? IE; are they powered by the UPS BATTERIES?”

• I plugged my Cyberpower 750A into a home outlet until it was charged (green light on the power on/off button). I can plug devices into either one of the USB Ports (2 ports) (Phones, Tablets, headphones, speakers other portable chargers, etc.) with the UPS unit plugged in and unplugged or with a power outage.

• Hi there, the SL750U USB charging ports will work on battery power if AC power is lost. Great question!
