will it work if there is no electricity

There is an internal battery that allows the alarm to operate for some time. The siren in the base unit will sound, but not sirens plugged into wall sockets. I have mine plugged into a UPS, and know it will operate at least 24 hours. It worked fine for me during the last power outage.

I don't think so. It works off of electricity and there's no manual switch available.

It must be connected to a natural gas line (pipe). If you don't have natural gas where you live, this unit is not for you. If you do have natural gas, it does operate without electricity so is good if you lose electricity.

Yes. The unit plugs into a household outlet. Most phone services do work when the power is out. If your phone service depends on househole electrcity, then it won't be able to phone out. (We just switched to a "voice over IP" ? service that is part of our internet and when power is out so is the phone.

Yes, it is an elctric opener and you would need electricity to make it work.

Should work as long as the device not being used is completely powered off.

If the appliance has a mechanical on/off switch you'll be fine. Things that have electronic switches do not always turn back on; if you can unplug and plug back in your device without having to turn it back on, these will work.

Yes. It works with a battery and does not plug into the electric. The battery has a very long life.

Electricity is needed only for the fan unit which circulates the air a little bit. In a power outage, the unit will still provide heat. Comes with a AA battery that goes in the push button ignition. I'd say if you can plug it in, it would help, but if you have a fan in the room (ceiling fan works great) you really don't need it.

It needs to be plugged in. It's portable and can be moved around the house, but it needs power.

Correct. Will work without power. Has a manual switch as well. Great switch for the price.

No this water heater needs to be plugged into an outlet to work, so if the power is out then its useless. If you are looking for one that might work in a power outage try the bosch line. I had an older model bosch that didn't require electricity to operate.

Without power the timer doesn't work. You would have to reset it like a clock.

If the electrical source for this product is your lamp that does not turn off, yes it will work. Anything then plugged into the device will turn on with movement. Or do you mean if the lamp is plugged into this device? In that case you can set it up so the lamp turns on when it senses motion and turn off when no motion is sensed for 5 minutes.

Yes, this phone will work when the electricity is out. That is why we have two of these.

Nope. It needs to be powered. I could only get one item at a time to work. If I had 2 or more things plugged in, it wouldn't work at all.
