Customers are pleased with the 650VA Battery Back-Up System, especially the battery life, overall performance, and ease of use. Many appreciate the reasonable price, adequate surge protection, and convenient USB ports. However, some customers have noted a slight humming noise and a few have experienced random alarms. A few others mentioned the unit may be a bit heavy.

    I purchased this unit to replace an existing APC brand UPS. I replaced the battery on my existing APC UPS, but it gave out within six months so I decided it was time to buy a new unit. I find it to be just as good or better than the APC brand, and it cost between ten to twenty five dollars less. I also found the manual to be more accurate in "backup time" than what I found on the Best Buy web site. I would gladly recommend this unit to anyone.

    Using this in a church to power a small rack cage in the sound booth that has two wireless microphone units and a Netgear 12 port multi-gig switch. Got it mainly for the switch because it can take 2 to 3 minutes to re-initialize from a power fail or glitch. Since we live stream services I did not want a prolonged interruption in case of a minor power issue. Size is nice and compact for a 650VA backup. Working great with no issues.

    Living in a rural area I experience multiple power surges and outages. I've recently experienced ongoing power surges that destroyed my previous computer. This resulted in my purchase of this with my new computer. Since installing this, more power surges and outages have occurred and this battery backup system has kicked in to save the day!

    Power went out the other day for over 3 hours. Kept my Modem, router, and small poe switch powering aps running from 11:30 to 3. The estimate on the device is is "308 minutes" and it at least made 240 that day. Super happy with my purchase and will be purchasing more!
