Pros: Bought this for the small footprint as it needed to sit in a small space. It was exactly what I was looking for and keeps my Fiber modem and ethernet adapter running for many hours.
I like that you can disable the alarm easily and that it was very straightforward to hook up and power on. Cons: none Overall Review: If you’re looking for a simple UPS to power a couple of small devices, this is the ticket on the cheap.

Overall Review: I picked this up to fit into a structured wiring panel to run a couple of unmanaged switches (heat is a concern so I don’t plan to run much in there).
It fits in it perfectly… we put two little blocks in the bottom it for it to sit on, that way the cable can fit in the base plug at the bottom of the panel.
The only potential downside is you can’t fit the (included) USB cable in the side as the UPS pretty much takes the entire width of the panel. This isn’t a problem for me, but I could see that being useful if you had a small computer (like a raspberry pi) to do some sort of automation or something.
What it does include though is two USB ports, advertising as “charging” ports, that would be useful for powering a raspberry pi without the need of using an adaptor and going through the inverter (which is inefficient). They provide 2.4A (it’s written on the top of the UPS, but the pictures don’t really provide enough clarity to see), which is more than enough for a headless Pi.

Overall Review: Does the job

Pros: – Works as advertised, supports my mid-range PC with dual monitor setup long enough to save, close my work & shutdown when outages/fluctuations occur – power supplied to my devices plugged in remains consistent & entirely uninterrupted
– Has lived through over a dozen power flickers & full on outages in my small town which is notorious for frying household appliances with our terrible power company (in southern Ontario, Canada)
– Alarm when wall power is lost and UPS has kicked on can be turned off/on
– Alarm, when on, is not excessively loud – the word alarm makes you think it will be screaming at you but it’s comparable to a microwave button beep, probably a little bit quieter
– When alarm is turned off, it still makes a very audible click when kicking on due to external power being cut off, so unless you have closed headphones or are blasting music you’ll probably know the power went out if you didn’t have any other indicator (like you had your lights off in your room mid-day or something) and can begin shutting your stuff off Overall Review: Would recommend. Make sure you check it’s dimensions before you try to replace one of your standard thin power bars that you have in a tight space because this thing is quite a bit larger. It’s also heavy (relative to regular power bars) and you will not be able to have it dangling from the plug (it also informs you of this in the manual, it must be oriented flat with plugs facing upward or vertically from the nail hole mount on it’s bottom side for safety).

Pros: Small and works great for the modem and router and other small power use. Cons: I have not found any thing yet. Overall Review: As of now, I would recommend this product. It has only been in use for 2 weeks

Overall Review: This product has worked fine and has lived up to its expectations. I bought a couple of the other larger 850w and 1 failed.
I am telling you this because I contacted customer support regarding the failed one and all they’ve done is give me the run around. They’ve told me it’s my fault and that I’ve overloaded it when I have not.
If you don’t care about customer service, then it works fine until it doesn’t. But don’t expect the company to back up their product when it fails.

Pros: Been waiting for a storm to submit a review. This unit maintained my internet connection during a Tornado Warning and subsequent power outage. I love it! Overall Review: I have purchased this unit again, and recommend it highly to anyone. I love its space-saving size and the amount of power it provides.
