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.

If it is plugged in to AC. Mine is not using battery backup and if the power goes off, the unit goes off.

I know there is a battery backup, but I have mine plugged into an outlet. I don't know how long the battery is supposed to last, but I wouldn't recommend it as your primary source of power.

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.

Yes, in fact I recommend using it while plugged in to a wall outlet and save your battery for when its most needed.

No, it is designed to protect your device, like notebooks, from power spikes, but not to prevent electricity blackouts.

9v battery is used as backup. The product description mentions this; however, the technical details say battery operated.... That's misleading

Honestly not sure. I use it as a backup or when I don't have access to an electrical outlet, so it hasn't seen a terrible amount of use

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

no, because it requires a wifi signal. If you want something when the power goes out, I would recomend a mifi from your wireless company.

Yes, I've used it, but not for a long time. I don't think I would plan for this, but in a power outage, it is great.

Sure, I plug it into a 12v back up battery I charge with a solar panel. But you could use an outlet.

It is plugged, the rechargeable battery is for back up for the programmed set-up, in case there is a power outage.

There is no battery backup, however the programming is retained when there is a power outage and when the unit is disconnected.

This is not a battery, it is a battery backup for electronics. It will provide some amount of run time for your electronics after a power outage depending on how much you have plugged into the device and will automatically power down your devices if so enabled. It does start to BEEP when the power goes out and we are talking about minutes use time, not hours, long enough to save your work and shutdown your electronics gracefully.

No, don't store, "generate" electricity. You madre your own battery from fruits or vegetables.

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