Experience: 1 Years

Works well

Battery compartment uses some kind of torx screw
Overload sensor occasionally trips when there's no load on the battery backup outlets.
There's no way to turn off the overload beep so for home use, make sure to keep a minimal load on the ups. Otherwise, every once in a while, you may get woken up overnight by a loud and persistent beep.

Experience: 2 Weeks


Works well
Decent capacity for the price
Outlets lay out well placed
None so far
Plugged in and tested great, perfect to keep a few smaller electronics going through a power outage.

Experience: 12 Months


the price is right
AC sockets are a bit "sticky" - hard to pull wall warts in and out.
I have a dozen of these, most 1-2 years old. Only one has failed, after a year. And that was a sort of 'intermittent" failure - crashed on a power bump (attached gear lost power!) but afterwards "appears fine". Obviously I can't trust it now, so have taken it out of service.

the others are ticking away just fine, and they all get multiple power surges daily, and once or twice a year a blackout.

I don't recommend them as a 'portable' UPS where you might carry it from de to deal and are constantly plugging and unplugging stuff. The sockets are a bit 'sticky' for that. Best to use them in permanent installations, where stuff is plugged in once, and never disturbed again...

Experience: 1 Months


replaceable standard battery type
cords are getting shorter every model
This was purchased in a crunch as a storm fried our previous UPS circuit board, and we could not run long without one.

The cord is shorter than its previous, which in our case was a little too short, so we had to "modify" our environment. The cord is still quite long, but 30cm less than its predecessor.

The thing I do like, and reason for purchasing this particular one was the battery is user-replaceable, and with a common battery type. Much cheaper than being forced to purchase a non-standard battery or an entire new UPS after a few years.

Only a month, one power failure during this time, and it worked as designed. Time will tell, but I have confidence in this brand.

Experience: 2 Months


Perfect for low powered PC,
Perfect for smaller itx builds, with total power load under 200 watts

Experience: 3 Days


Cheap and quiet
Ugly design
Does what its supposed to do at a reasonable price. Usb port is a plus

Experience: 3 Days


- Small form factor.
- Decent and simple software.
- Haven't seen any so far.
Connected this at a family members house to keep the modem, router (Asus N66U), and an external HDD going. Indicates 29 watts of load and 89 minutes of run time. Software has features for shutdown and is quite simple and easy to use. Bought it specifically because it is compatible with QNAP NAS (USB control), which I will be deploying there is a few months.

Sticker on UPS recommends 8 hours of charging before use, so I plugged it in one day and then set it up the next.

Experience: 2 Weeks


Parfaite unité de secour
Permet de fermé et sauvegardé les travaux encore lors de panne de courant.

Experience: 7 Days


Compact, lots of outlets, comes with software
Not enough battery power to run a computer with a 750W power supply
Bought this unit to protect my main computer, but it will scream at me if I do anything more than run a web browser and the calculator. Alarm goes off immediately if you draw more than the 330W the battery is rated for, and shutdown follows quickly. Word to the wise: if you're looking to protect your computer, buy something with a higher wattage rating.

Other than that, the unit is solid, well-made, well-packaged and comes with easy to use software.

Experience: 20 Days


Protect your precious equipement perfectly
no LCD display
I've buyed two of those to protect both of my 55" TV against surge. This is a must have for everyone who have expensive TV setup. Don't trust expensive power bars, buy an UPS for the same price. It will protect your equipement and let them run in case of a outage giving you time to shut them off normally.
