Works as Designed, but NOT for PCs
By Mark L. on Reviewed in the United States on June 29, 2014
I want to make something abundantly clear up front: This is NOT the UPS (for the uninitiated, that stands for Uninterruptible Power Supply, which is essentially a battery backup unit for whatever you plug into it) to buy for your desktop computer. Your desktop computer, screen and peripherals probably draw almost that much power combined when they're all in use, and the 350 volt-amps of output that this unit can supply will not run them very long, assuming the UPS doesn't just cut out as soon as the AC power fails. I wouldn't consider anything smaller than a 700VA UPS for a typical desktop computer setup. Besides that, this particular model lacks hardware and software to communicate with your computer and trigger an orderly shutdown when the battery power runs low. However, this unit can be ideal for many other kinds of equipment that you want to keep up and running when the power fails or hiccups. I bought two of them for a college dorm's wi-fi equipment. One UPS powers a cable modem and wi-fi router, and the other powers a wi-fi extender. The reason I decided to put these pieces of equipment on battery backup was because all were malfunctioning frequently, most likely due to surges and ebbs in the aging building's electrical system, or maybe due to students' tendency to trip circuit breakers. (Did you ever live in a dorm where students didn't trip circuit breakers with annoying frequency?) 350VA UPSes like these can run low-voltage network equipment for hours. Since I installed these units, the only times I've had problems with the dorm network equipment has been when the cable Internet company service has dropped.

Lasted 2 years and now battery failed
By 161803398 on Reviewed in the United States on August 9, 2025
Worked okay for about 2 years until the battery has failed, and now when power drops it just shuts off my devices. Unacceptable how short these last and the amount of toxic waste they create by throwing them away.
