Is it used for battery backup?In case the electricity goes out.

Yes Louise, In addition to battery backup, the battery allows you to go portable around your property as long as you are within range of your wifi network.

It will do that, but it will go for about 6-7 hours before needing power to charge it again...

Our electricity went out for a couple of hours today, so I thought the battery pack would be a good idea. Then I realized that without electricity, we would have no Wi-Fi. :D Money saved!

It surely could be. We installed it to make the radio portable. We use it out on the porch, when working in the garage and outside. It is a nice feature.

You could look at it that way - or like a laptop - it doesn't have to be plugged in and it can go where you are - if there is a plug or not.

Yes. As well, you can unplug the unit and move to another room, etc., while the music keeps playing. Or, take the unit outside and still listen for an hour or two.

Actually you do not need a battery backup for these items. A high quality Surge strip will cover them. The Battery Backups are really meant for computers, phone systems and medical devices that need to stay on during a brief power outage. I use one in my office for the Cable Modem (voice and internet), the Router, my main office PC, and the cordless phone base. I have a couple of these 350's in another office on the phone CPE (basically a modem), the phone switch and internet router. If you do get one think about what gets plugged into the battery side and what is on the surge protected side.

No. After use I unplug from electricity. I use this only once a moth to backup my computers.

No. That is one of the limitations of this product. It is also one of the reasons that the price is lower than chargers that will still work if the power goes out.

My home security system uses this. I think it is the back up power in case of blackout.

Yes. I use it to keep a small scissor lift battery powered up. stays plugged in 24 /7.

Yes, it does require electricity so it is totally worthless if your power goes out.

Logic indicates "No." The assumption is a loss of electrical power hence a battery backup pump. If power is lost to the house it would make no difference how many circuits you have. Just replace the battery every 3 years and check the electrolyte (if necessary) regularly. Of course, it should be understood to check the load on the circuit. The battery charger load is negligible so the concern should be other units on the circuit. Most household circuits are limited to 15 amps. Do not overload or a circuit breaker will pop leaving you with nothing.

Most likely. I never heard of one with clock battery backup. If it doesn't have a remote sensor, nor an AC adapter, it's only using elec for the clock, so you're probably not going to save much elec with it controlled.

Yes, you can. It's not safe unless you have it plugged into a UPS though, keep that in mind. If power cuts or dips you'll have to start over.

The unit has a compartment for two button type batteries (supplied with the unit) that back up the memory if the power goes out. So the answer is: yes.

No. It has no batteries to use for a backup. So if the power quits, so does the phone

HA! I asked them the same question! No.They said that the whole purpose of it was to monitor raw energy. a battery backup will give you inaccurate readings. that does make since, as this unit needs to read spikes and drops etc. as well as normal current pull.

Yes, there is built in backup. I don't know how long it will last, but definitely long enough for the typical power outage. Mine has been unplugged for over a day now and the display is still working (unlike the timer itself, which is permanently off, and ready for recyling).

No, it only Works grid tied. Once there is no power from the grid, it stops working. It is not for back up systems.

For backup in cash power goes out and it will keep the data. It runs otherwise on electricity.

I run this from the outlet, and it's been exceptionally reliant. There's a back-up battery for emergency power outage.
