I've owned 3 of these for between 3 - 5 years and use them to ride out short outages and provide additional smoothing for any power spikes to protect computer equipment and entertainment center. I've recently purchased a fourth for an additional home office. In the time I've owned them I've had to replace two sets of batteries, but the units themselves have continued to perform without faults.

As others have mentioned, the units can be quite noisy when initially charging or recharging after an outage, and charging can take quite a long time (24 hours or longer if fully drained).

I've recently purchased a fourth for an additional home office. In the time I've owned them I've had to replace two sets of batteries, but the units themselves have continued to perform without faults.

As others have mentioned, the units can be quite noisy when initially charging or recharging after an outage, and charging can take quite a long time (24 hours or longer if fully drained). If noise is a concern you can consider a lower power fan-less model that may be quieter but will give you shorter time off mains supply.

If replacing the batteries, in this model you'll need a Philips PH1 screwdriver with a 125mm shaft, as the screws are set quite deep into the body. Also be sure to take accurate measurements of the battery dimensions if you can't source the same model battery by part number. For example, I could not source YUASA replacement batteries in an older unit so had to find an equivalent format by another manufacturer. I found Eaton badged batteries in this instance, but there are other manufacturers that market similar dimensioned batteries that would work. The tolerances for fitting the batteries are quite tight so you will want to get this right.

Will never buy or use again, fans are super noisy and run all the time, randomly beeps during the day and night. These beeps are the unit turning off its outputs (and killing power to anything connected to it).

It seems to work fine. Some caveats:

* It requires a USB-B cable if you want to use the control port. And for some reason the slot is at the front rather than the back, so it looks a bit awkward when you plug that in.
* When you plug it in the first time the fans go full speed for more than a day, only then it gets silent. It seems to work fine. Some caveats:

This is a very basic UPS but it is rare to find one at this price with Automatic Voltage Regulation. I get a lot of undervolt (brown out) issues and since installing this UPS those issues have disappeared.

I bought this to replace a larger rack mounted (4 battery) Eaton UPS. It's not going to give me as much time in the event of an outage, but without a fan that runs constantly it is nice and quiet.
It took approx 10 hours to charge completely when I first plugged it in, and the fan ran the whole time, but once done it does not cause an issue.
I've had it installed in the office for a few weeks now,. It's a no fuss, simple and effective machine. I bought this to replace a larger rack mounted (4 battery) Eaton UPS.

The fan does stay on for 24hrs when first plugged in but does eventually stop so be patient. Apart from that its been a great UPS for the month that I've used it.

Working well. I got close to an hour uptime with a 120W load.

It does have a fan, which is quite noisy. It seems to come on only when the battery needs charging, so the unit is silent most of the time. Working well. I got close to an hour uptime with a 120W load.

A great little UPS that you can set and forget, that helps protect equipment and keep the network up during power glitches and outages.
Pros: Small physical size, larger battery capacity, IEC outlets for secure connection of equipment.
Cons: Cooling fan, which operates under heavy charging load, is quite noisy in an office environment. A great little UPS that you can set and forget, that helps protect equipment and keep the network up during power glitches and outages.

USB connection to PC, 2000va, good price point.
Bought recently.
As I currently have builders & electricians pulling random fuses & turning off power at random times, the UPS has kept my computers & monitors going with no glitches.
Very happy with it. USB connection to PC, 2000va, good price point.
