Average Reviews:
(More customer reviews)I have one of these and it did its job during a power outage yesterday. This UPS is cheap and works perfectly fine but beware the pitfalls of stepped square wave UPS's. During yesterday's particular outage, this unit kicked on to protect a computer system. The system shut down fine but the power adapter for the USB hard drive that was plugged into the UPS overheated trying to operate on the stepped square wave power and failed destroying the USB enclosure and drive in the process.
The important thing here is that this failure was NOT the fault of the UPS. It did exactly what it was supposed to do; however if you are protecting valuable data or critical infrastructure with one of these just remember you can step up to the category of true sine wave UPS's for only about $100. The price difference is well worth it!
