Saved my work the other night
||Posted . Owned for 1 month when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.Does just what it's supposed to. A storm knocked out power the other night but this UPS gave me plenty of time to save my files and close out the system. I got everything shut down safely with time to spare. The unit's power out alarms also worked as both of them (another one on the game system downstairs) loudly alerted me to the loss of power. The unit itself feels well-constructed. Outlets are pretty well spaced to allow for DC adapters, though I wish they were spread out farther and turned 90deg so they were side-by-side instead "vertical". Regardless, it was a good purchase.

Efficient service and perfect price
||Posted . Owned for 1 month when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.In fact, I was afraid of its cheap price. I don't think it will work well, but by using it, it has been proven to be very effective and the price also very competitive.

Great Battery Backup
||Posted . Owned for 10 months when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.This is a must have when you don't want your internet to die along with the power. This kept my internet going for about 6 hours until it finally gave out. I am a heavy user so I must have one of these ready to go in lightning and brownout prone Florida.

Reliable power...
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.My test had a single lower power computer with 22" widescreen monitor running for about 15 minutes on backup power. Could have gone longer, but that is all I had time to test.

Does what it is supposed to
||Posted . Owned for 1 month when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.I live in a rural area that often suffers from power jitters. The power flickers on and off and on again. This unit keeps my NAS, router and modem going long enough to shut down.

Power supply
||Posted . Owned for 1 month when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.The Cyberpower backup station has plugs that are evenly spaced along the device that make it easy to place a variety of devices. One does not have to open the device up to attach the battery, as a prior product that I have purchased. The USB connection was not compatible with my phone, so points off for that strange feature. I have not had a massive power outage yet, so I can not tell how long the battery may actually last. Remember, these are not generators, and supposedly only useful to allow you to shut down your devices safely in event of a power loss.
