Customer Ratings & Reviews

CyberPower 450VA battery back up works great. True surge protection for all outlets (4 +4). Surge protection + battery back up for half of the outlets (4). This is the third one of these we have bought (others for elderly family members).

Great battery backup for those with multiple laptops, tablets, etc. 4 surge protection outlets. Has worked very well for me.

Easy to hook up. Small enough to sit under my desk and still have room for my feet and garbage can.

This unit is great to protect my pc, cable modem, and wireless router. If the power fails, the items mentioned stay on, which keeps them safe. This allows me to finish my work on the PC, and then I can safely shut it down. Also you can use it just for the modem and router's power adapters, which keeps your home network going eve if there is no electricity, such as during a storm. I highly recommend this product.

This UPS was compact and suited to the small load I had.

This is a definite improvement from my old APC UPS. It is much lighter and smaller in size which makes it easier to store under the desk. However, this is a "bare-bones" battery backup that will keep my computer running during short-term power outages. I didn't need anything fancy, and I didn't use some of the features from the old UPS. I researched the cost of a battery replacement and this system was only a few dollars more than a replacement battery for the old UPS. Purchasers may opt to get the SX650U or SX950U if the want more backup power. Also those units have UPS charging ports and connections to a PC for system monitoring. The lack of USB charging connection was the thing I was disappointed with on this unit.

Good battery backup. Serves its purpose. Downside is only 4 of the 8 outlets are connected to the battery while the other 4 are surge protector only.

Great product at a great price, and the delivery service was excellent!

So far no issues, works as it should. I bought this to protect my projector in the event of a power failure. Most people don't think about this, but if the power goes out while the hot projector is running it may damage it. So far I've only had this happen once and the backup allowed me to power down the projector and the fans to cool it properly. Just make sure you plug into outlets that are battery protected, because some are surge only, but it is clearly indicated.

Excellent product. Easy to use. Great value. Would recommend.

Much smaller and lighter than my previous back-up battery. Easy to set up. Hopefully will last a long time.

Great device. Easy to install and use. Two sides, one for surge and the other for surge and battery back-up.

Good value has a removable battery, so when its life is up, you can replace the battery. I use it as a power BackUp for my modem, Router and NAS.

Works well and extremely easy to implement. Much more robust than the specs seem to indicate.

Works great supports my computer and all devices attached to it and holds power long enough to shut everything down properly

I have had no problem using this to prevent damage to my Tv during power fluxuations.

This is my go to battery back up for the office. Works great for the typical workstation. Easy to use and lasts a long time.

A UPS should be considered a necessity in this day and age. Whether it's to protect your devices from spikes, brownouts, or generally "dirty" power, you're doing yourself and your gear a favor by having one of these.

Outstanding batter back up, my son told me about these and it's truly helped when the power has gone out.

Bought it to back up our TV. Works great if power fails. Price is reasonable.
