Purchased for my homebound mom to keep her from having to wait for someone to reprogram settings on the picture frame after a power failure.

Great small UPS to keep my cable/phone modem operating in case of a power failure

On one of the power failures I lost a router, had to buy new one so got this to keep it running until I

so a power failure during hard drive access would be bad

It has saved me from some minor headaches from brief power failures (no real major ones yet - thankfully)

In my country every time it rains we got power failure, this UPS has been helpful staying online while power returns

So I should now have around 8 hours of Wifi Internet access during a power failure.

Well we haven't had an extended time of power failure

Looks nice in my office, and has already gotten my router and modem through a minor power failure (a few minutes)

, very loud beeps that this device makes during a power failure, so it defeats the purpose of providing power backups to devices that make noise during a reboot (like Alexa does).

We had a power failure that lasted almost 2 hours and my worst nightmare came true

I don't worry about my VOIP , security alarm and power failures

It works good, now I don't have to worry about resettling the modem after a power failure.

I do own 3 others of the model without the charging ports for 4 years and they have performed as expected during power failures (4-6 hours) and the batteries have not needed replacing

This UPS has been great and is working perfectly for it's intended use: I use it for backing my FiOS router and Sprint Airave to keep them going when there is a power failure.

It works fine and switches over during a power failure flawlessly

Seems to keep our always on camera running in a power failure.

I consider that test enough as I wanted it primarily to back up my wireless network and phone (voip) in case of power failure.

That enables me to maintain my internet connectivity despite a power failure

About this fully intended purpose of keeping my network online during a power failure

Power failures are less of a nuisance than they use to be.

Power failures are a big issue where we live

During the first power failure it lasted almost one hour and has gone down hill since

Not having had any power failures recently, I resorted to testing the unit by unplugging it

We recently had a power failure and all three units kicked in without a hiccup.

Using it to protect our telephone base station from power failures, which are all too common in Florida

All in all covers my connection needs in case of power failure.

Comcast can't incorporate something in their modems to allow for 10-20 second power failures.

Also, Unlike Many Other UPS Devices -This UPS Does Not Emit the Annoying "Beep - Beep - Beep" during a power failure

Nothing worse than working and then all of a sudden having to deal with no internet due to power failure

I had no power failures seen I got it...

All in all... a great, and well thought-out idea.

but if this doesn't bother you...go for the BE550G!But for aesthetics, no wall-wart and the fact that this device works as
