Tripp Lite 550VA UPS Battery Backup Uninterruptible Power Supply Surge Protector, 10 Outlets, Dataline Protection, USB Monitoring, Home & Office, 3-Year Warranty & $100,000 Insurance (INTERNET550U)

Seems to work fine. I put it in the bedroom for the clocks and etc....

This product works as advertised.Buyer beware: if you are a first time shopper for a UPS, this one will NOT maintain power for a beefy desktop computer / monitor setup during a brown out. Not even for a second, it will simply turn off the UPS killing power to everything else plugged in. This was my first purchase of a UPS, and i misinterpreted some technical information and assumed that it could handle a big computer, but only for a short amount of time, but this is NOT the case.After speaking with customer service (A++ customer service by the way), I resolved my issue of random shutdowns of the UPS by plugging my computer into the non-battery-back-up side of the UPS. I would take a star off for this product not doing what I had hoped for, but they are not at fault, as the product is not advertised to be able to handle a 650W power supply gaming computer + peripherals.PROS:-solid build, feels "serious"-works as advertised-maintains power for small power consumption devices such as a router, clock, raspberry pi 3 etc.-software works with windows 7 which is what I still use-really nice warrantyCONS:-manual for my specific device had to be found online-software had to be found online-UPS wattage rating is somewhat vague for the uninformed**not their fault

This is a really nice and inexpensive UPS that I used to replace my old 300VA unit that no longer had the number of plugs I needed to keep my router, switch, modem, and server all up and online. I haven't really had too much of a chance to test this out in a complete blackout situation yet, but through some initial testing it appears to work fine just as it should.Admittedly I bought this not realizing this was the "ultra-compact" version of Tripp Lite's UPSes. This isn't too big of a deal I suppose, but it does mean that if you have power bricks to plug in and not just straight 3 or 2 prong plugs, you will not be able to fit everything onto this device. I had to buy little 6 inch plug extenders just to be able to comfortably plug in all my equipment. This wasn't a big deal, though it is something to keep in mind.I also have to agree with other people that Tripp Lite's software solution for monitoring these is IMPOSSIBLE to figure out and honestly not really worth the time. I was hoping that there would be some simple desktop application where I could mute the UPS, but I haven't been able to figure this out yet. I think this is something Tripp Lite should work on for these products and it would provide a huge bonus to the product itself. I am docking a star because of the fact that they advertise this as if it's simple, easy, and straightforward to do once you get the UPS but it clearly is not. If it simply weren't marketed that way, I probably would give the UPS five stars.

I'm in a rural area that frequently has power outages. We keep our devices fully charged for this reason, but I bought this for the router so we don't lose internet. I don't know how long it will last but we recently had an outage for 45 minutes and I was happily using the internet on my laptop the whole time!

I first bought it for my PC/Monitor. I didn't really care about battery life, I just wanted something that would allow me to shut down properly, or not shut down at all during a power blink.I plugged it in. Seemed at first as if it was working properly. Then I turned on a game that used a good bit of power, and it started beeping loudly. After 5 minutes of beeping loudly, it just cut off. The power was plugged into it the entire time. I looked it up, and it said I was basically using too much power...or so I thought. My power supply will use up to 750watts, not counting the monitor. Again, I was just wanting something to prevent bad shutdowns.So I ordered another PSU that went up to 1500 VA. I spent 3 times the price, but also with it I got to see the actual usage readings with a display etc. I did this expecting really high usage. Turns out, the max usage I have seen from it was 375W/VA. And again, that is with heavy graphics on a high end PC. Most of the time it's less than 200. As I sit here with just a browser open, it's using 150-160W - counting my monitor. But the usage went over 330 W I guess that one time, and even though it was plugged in and not going off the battery - it shut down after 5 minutes.So I figured I'll just use it on my router/modem. A little bit of a waste, but I work from home and the power sometimes blinks, which resets it all. Or in the event the power is out for a few hours, I could still maybe have internet that entire time because it's such small amounts of usage. Save some mobile data, it could pay for itself in time. Plug it all in, I assume it's working fine.Nope. My wife plugs in a vacuum cleaner into the same outlet, and it immediately shuts down. Doesn't use it's battery backup, or anything, just shuts off and starts beeping. I assume the vacuum cleaner affected the amps/volts or whatever, it detected it and shut down. But why does it need to shut down instead of disconnecting the power source and using the battery backup?I've only had it a few weeks, and the power hasn't blinked in that time. I guess I could flip a switch to test it. That is the ultimate test, but it's been nothing but issues so far. I will be surprised if it works properly when the power goes out, it certainly struggles to do it's job when the power is on.
