It plugs into an electrical outlet, no batteries. I would not recommend this phone though, it's terrible. The answering machine often deletes messages while your listening to them, the display does not back light, and a number of other faults. We are replacing the phone because we are unhappy with it. Good luck to you.

I measured it at 1/8"; labeled at 5V DC. Radio Shack will have the 5 V power bricks with the proper connector for the 5 V version. However you do not need external power supply as USB USB connection provides the required 5V required.

There is no external power supply. The phone line and the batteries suffice.

There actually is no battery built into this. It's a hot shoe adapter but it won't power all things you put onto it, if any. I bought it so I could mount an external microphone on my dslr and it works great for that. Hope that helps clear some stuff up for you

No. This device does not need external power. Direct plug and play ( like a thumb drive)

I only had an 8GB card - but I found the batteries ran out of power long before the card was full. I recommend using an external power supply with this unit.

No, you have to have an external battery. The higher the amperage the better. I put the fencer unit and the battery inside a wooden box with a cover on it. I then run the wire to the fence up a piece of wood attached to the side of the box and the ground wire out one side of the box to the ground rod.

It requires a power source. You can use a BEC, or a (4) cell NiMH or NiCad battery (4.8v-6v)

I just tried this and yes it will continue to work with no external power as long as the batteries are good. I started it and unplugged the power cable and it just kept going.

I have AT&T; U-verse and the phone works well with no batteries required. The speakerphone does have a 120v adaptor for power.

They do not take internal batteries. The transmitter uses appreciably more current than the receiver. I power the transmitter with house current and the receiver is powered by my electric golf car.

I think there is an external power port. The units are in another location and I don't know if they have a power port. Note, I use the best c cells and have not had too much of a drain problem. Inexpensive c cells go fast. Inexpensive rechargeable c's are nothing more than AA's in a bigger package. Only expensive C's that hold at least 4000 mha will last longer.

Only one needs power, that would be the one that stays in the house. It needs (6) C cell batteries, I believe there is an external power supply for it, but I never used them. The batteries last quite a long time, depending on use of course. The wall unit outside needs no batteries. Hope this helps. I have in operation now many of these units, and they work just fine.

It requires 3 AA Alkaline or Manganese batteries. They are not supplied with the unit. There is no provision to run with external power. Manganese batteries have a shorter run life.

This unit MUST be plugged in to operate. Unfortunately it does NOT contain a standalone battery.

There is no internal batter in this unit. It does have to be plugged in to receive power.

They do not supply a battery power supply. If you want that you will need to design it yourself.
