Perfect size and price to protect my gaming system, wifi hub, and UHD TV. You never know when the power will drop out so protect those electronics

I needed new UPSs after my others got so old they would no longer hold a charge. I bought 2 of these at the same time. I’ve already lost power several times since I bought the new ones. They worked perfectly! Also much smaller than my older UPS. I also like the fact it has a very long cord (approx. 8 feet). I’m going to buy a couple of more to have as “back ups” for extended power outages and to put in other rooms.

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).

Bought it to keep modem from shutting down during power outages. Works as it should.

Works great, keeps my wifi alive when the power goes out. Keeps everything safe from power surges too. This has way more surge protection than other brands at the same price point.

works very well. so easy to setup. I don't worry about power outages (which there have been) interrupting essential equipment from working.

Works like it's supoposed to. Can't say much more about this product. I use it to protect my Xbox and pc

I bought this because I had to move somewhere where the power goes out a lot. I’m a student and my professors like to do a live, webcam on, exams. If the power goes out and I’m disconnected the professors aren’t very understanding and have been know to either make you turn in what you have immediately, or fail. I couldn’t take any chances so I bought this battery back up to connect to my WiFi so that I don’t lose internet during class and so far it’s worked great! It’s saved me a few times already, definitely worth the peace of mind.

Great back up battery and good price. Was very please with the product. No outages so can't test it yet but works great out of the box.

Small, but powerful. It powers two hard drives during blackouts and so far it holds them for at least twenty minutes.

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

I’m using the SE450G1 to power my Arris SBG10 WiFi router/modem combo, not as a UPS or surge protector. Fully charged it powered the router for 107 minutes (1hr 47min). Tried an experiment to see if I could squeeze more time out of the battery. I turn off the routers 5GHz band and set the 2.4GHz band to “Tx Power Level” Low. The router still worked fine and extended the life to 130 minutes (2hr 10min). Seems to do the job I bought it for well, we’ll see how long the battery hold up.

Easy to use. Lasts long enough to shut down a home computer system if you are on site at the time. Not for business systems or if critical data is at risk.

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

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

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 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.

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.

While this unit doesn't support cold starting and supports a relatively low wattage, my use case was to power a small Ethernet switch during power blips and it can certainly do that and has a good run time for a low wattage device.

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