Customer Ratings & Reviews

I'm very pleased with this CyberPower Battery Backup. It is well designed and offers plenty of battery plus surge protected outlets and a good number of surge protected outlets as well. I always bought APC in the past but if this one lasts as long then I will be buying more CyberPower.

it works awesome and has plenty of outlet plugs plus a couple of extras for other future purchases

I use this unit to lovel the power from Rocky Mountain power. Because I am at the end of my line the power can vary from 100 volts to 120 volts. This unit with the battery backup protects my router, Poe internet provider, and computer from burning out because of low power as well as line surges.

I have already had other backup batteries and this one suit perfect for my small office, i connect my computer, my laptop, a printer, 2 monitors and a CCTV set, we have some blackouts in our office and it has stand for the necesary time to the energy to came back, good price for a great product.

I've already had a brief power outage since installing and it gave me time to safely turn off TV and accessories.

This device works great. It has saved my computer from 2 flash outages so far since I bought it.

It keeps everything going for a few minutes if the power goes out so u can finish what u r doing

Good price, powering everything I previously had on a smaller size ups and have had no problems

Needed a power backup and found this one to be very good and very compact when compared to the one I replaced.

I am very happy that I bought this item. I would definitely recommend this product to family and friends.

Simple plug n play with this unit and my iMac 27". So far it has kept up the iMac during a power outage that lasted a few minutes. USB cable to communicate with iMac was plug n play, no additional software needed. Little heavy, but that is expected. Works very well for my home office needs.

I've been using "CyberPower" UPS products for 4 years. This is my fourth CyberPower UPS purchase this year alone. I use a 1500VA unit to protect my workstation, A 1500VA UPS to protect my high end audio equipment, A 950VA to protect a TV, and satellite equipment, and lastly, this 850VA CyberPower UPS to provide 24 hour power protection and power failure use for the needed security system. The "CyberPower" design provides a full sine wave, clean voltage for sensitive electronics. The smaller UPS devices incorporate a digital sine wave emulation that beats the competition hands done. Automatic Voltage Regulation cleans up low power, over power, spikes, surges, and short brown/blackouts (at the cycle level) without switching over to the battery. This means much longer battery life and power consumption, and the main circuitry is off except for a very small low power battery maintainer after a full recharge from use... Longer UPS life and NO noise. Gave up on the old "Red and White... Too many failed too soon. Our main server UPS is a nearly 4 year old 2000VA with battery packs. Same batteries! 4 years of Central Florida lightning delight with power dips, surges and outages. RSOrlando Retired Energy Management Engineer Aerospace & Theme parks, Orlando.

Good product. Does what it is supposed to do. Battery last as long as it is intended to.

Good price for a UPS with Automatic Voltage Regulation (AVR) which is a feature that if voltage drops below about 110 (but at least 90) the unit will boost the voltage back up without switching to battery. This is most useful in older buildings or where power is iffy. If power goes out completely or 1 branch of 3-phase is lost, unit is supposed to switch to battery. We'll see how it's doing in a year or two.

Perfect for what I needed it for. Low profile and big enough for all my appliances.

I have been a strict APC user for years but their customer service has been increasingly difficult to work with. They also do not stand behind their warranty like they did 15 years ago. CyberPower has been great to work with and the quality if their products have improved much over the years. I now purchase their products exclusively.

This UPS provides enough outlets for the typical workstation with all of its peripherals and chargers. Be sure to plug in your computer, monitor, and hard disks into the battery back up side, and your chargers for devices into the surge protection side. Works well.

This b/u system is a definite improvement on our old system. Though another power b/u slot on the unit would be nice, this unit was easy to set up and worked fine during a brief power outage.

I can run 3 computers on his backup. was able to test during last weekend's power failure.

Good quality and competitive price. Will definitely buy again from Bestbuy!!!!
