    I had a power outage yesterday, and my PC was in sleep mode. The device was beeping, so I went to login to my computer and immediately lost power. So, that means the battery was not powerful enough for me to start up my machine and shut down gracefully. I might have too much plugged into it, but I want everything running through this device. It seems like I should have bought the bigger unit.

    So far I have no complaints about this little backup. I purchased it solely to protect our modem, TV, and satellite receiver and it's done excellent so far. I know we've had at least 4 complete and 1 partial power failures since I hooked it up and we've yet to have any issues due to them.

    This UPS is best for low power devices. Don't let the pictures fool you, there's no USB port on this model.
