Bought this to replace a 600VA battery backup that had gone bad, and was glad I did. This is used to keep my home network (cable modem, wifi router, and cellspot) operating during power outages. The old 600VA would give me between 30 and 45 minutes of service before it went completely out, and this one, although not totally twice the battery power, tells me will give me over 300 minutes (5 hours) of backup, ehich I didn't actually believe...but sure enough last weekend's storms knocked out the power for 7 hours...and this thing kept it going for 280 minutes (4hrs 40 min). So very happy with the upgrade and the backup power.

Great UPS at a great price. I primarily use it to backup my Internet Gateway Device. This way, when I have brief power outages, my gateway stays up and running. Also, my laptop stays up and running off its internal battery. I can maintain my work-from-home online status for over an hour during power outages.

Only uses a single 12V 9Ah battery, unlike the prior versions Sams used to sell that utilized a 24V system with two 12V 7Ah batteries. But in a pinch, when there isn't any other option, this works ok for a hundred bucks (on sale).

Our household uses CyberPower Battery Backups for our garage opener mechanism. This means our garage door doesn’t lock us in or out when there is a power outage. Reliable protection in an electrified world.

Since so many of the items you want on backup, such as cable modem and WiFi router have their own at plug power adapters, it's a bit tight to plug much else in . My solution was to use a 3way plug adapter for my power adapters, then I was able to plug in desktop and cell phone mini Tower

I purchased two of these to replace old UPSes that the batteries had failed in. It was going to cost more to replace just the batteries than Sam's had this on sale for. It is a decent unit, but I will say it would be a 5 star review if they had at least two of the outlets setup for power bricks, especially with the location of the power cord for the unit. Again it is a good product with a few tweaks it could be a much better product.

This backup still works, which says a lot for the way it arrived. FedEx gave us a tracking number and delivery date 2 days after the order. On the delivery date my office received tracking notice that the item was delivered. It wasn't. The following day I received FedEx notice of delivery for that day and every business day there after for the next week. It never arrived. After contacting Sam's 2 weeks after the order date the rep. stated it would arrive that day. It did, but it was not my office's "Normal" FedEx delivery driver. This driver left the package in a corner and didn't notify the office manager of the package arrival, yet the tracking said my office signed for the package. The box it was shipped in was destroyed and retaped in all the corners. All the inner air bag protective packing was destroyed and the manufacturers box was bashed in. Basically the driver dropped and ran. The package looked like it was part of a World Cup soccer match that went badly. Time to change shippers Sam's Club.

Got the product home to replace a failed unit from another brand. Easy to set up, backing up a computer, monitor, and modem. Quiet operation. It covered well for storm power interruptions the next day.

Seems to do a good job. So far so good. Using one for my office and one for my FIL electric lift chair because where he lives he has a lot of power outages.

As an at home worker, if we have a brown out meant waiting for the internet to reboot back up. Now with these on my computer and a second on my Starlink - brown or black outs means I can continue to work for 400+ minutes. What a win for me! Solid battery backup.
