I want to know something base continues to function even without electricity or you must have energy to use it?

I would assume the speaker phone function on the base would work since that is directly connected to the phone line, but the hand held phone would not because it is just another cordless phone.

The base must be plugged in at all times for the remote sets to communicate with the vase

This is solar light, needs sun to light bulb inside, does have 3 levels so you can shorten it, but it does not run by electricity. There is a base. Hope this was helpful PS I just ordered 2 more now have 3 looks great and works excellent out doors better than the little solar lights

It does not require electricity. It simply connects to you incoming water pipe

It does not use any battery. It connects to your source and the power is derived from your source i think.

No electricity is required. Either a gas line (as I have) or propane will work. It is a GREAT grill!

Hello you do not need electricity, it runs on the internal battery. When the battery is dead you purchase a new unit. That is what makes this unit so handy you can put it anywhere on a shelf, end table, bookcase on a wall. It doesn't have to be mounted solid to anything. Ernie

the item is solar powered. You charge it in light, there is no 'battery', just a capacitor that stores energy.

Not sure why you thought batteries were needed. It doesn't need batteries. It' a single line direct wire connect to the phone jack. As a matter of fact it's the only phone we have that will work during a power outage as our other phones are battery operated but the main base station does require power and the base itself does not have a battery.

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.

Jesse R. is right. It requires constant pressure for the time you need the light. No pressure, no light.

No battery required. It uses power source and you need to have a long power cord of your own.

It does not require power. It closes automatically when it gets cold. I think it works the way a coil thermometer works by taking advantage of the expansion and contraction of metal with a change in temperature.

Not sure I totally understand the questionYes it is fairly lo energy- my electric bill definitely went down a couple dollars when I got it. It is movable, but not so portable- not usable outdoors, and once it is set up, well it has wheels, but it does need to be vented, so it is rather fixed in position while runningHope this helps

It needs electricity. It runs a fan to rocket the heat out and to cool it off after shut down.

It is not at all powered by electricity. There is a battery operated monitor but I don't think that would be an issue. We don't use that feature anyway.

No electricity required. The system used your body weight against gravity to provide the load. The higher angle on the slider supports, the more work it takes per repetition.

No it doesn't need to be kept on. Pay attention to how it makes you feel - such as do you feel out of balance or not well. The negative ions produced by the lamp are energy and they affect our energy - our balance. I found that having the lamp in a neutral place, not close to me and not keeping it on made me feel better. Listen to your body and pay attention to how you feel. I only turn mine on a few times a week.
