Good for the price
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.This unit was easy to install and simple to use. I did notice the battery rattled around in the case, so I opened it up and put some heat resistant material in to hold in steady - that's the reason for the 4 and not a 5 rating.

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.

small footprint for tight spaces
||Posted . Owned for 1 month when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.Good value for the money. No AVR since there wasn't one in stock. Won't support very much equipment for more that 5 minutes. Better to by new than to replace the battery. I've used CyberPower UPS's with AVR for years. Batteries die before anything goes wrong with the UPS.

CyberPower battery back-up
||Posted . Owned for 3 weeks when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.I bought to replace a 6 year old one of the same brand that stopped working. Order process was simple and device arrived when expected. The outlet orientation was rotated 90 degrees from prior the prior unit and it made 'plugging in' a bit of a jigsaw puzzle. Orientation makes sense if just a plug but 4 of my 7 devices had mini-transformers (bulkly) instead of a pure plug.

Worked perfect but has some loud alerts
||Posted . Owned for 5 months when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.Saved my butt during a power outage when I had to shut off the circuit breaker due to work being done at my house. The only complaint is the loud beeps it gives when operating can drive you crazy and I have not found how to shut that off yet.

Perfect Backup System
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.Not too bulky, perfect for office computer. The plugs can be a little awkward due to wall warts - should be rotated 90 degrees so that the cords don't block each other.
