Power source? Electric? Battery?

The bike, itself, is powered by the person pedaling it. But there is a small and useless battery-powered digital display; it is supposed to let you know how many miles you've pedaled, but it doesn't work.

I returned it, seemed to be flimsy and something didn't work well, but I don't remember what it was.

The power source is a little circular 3V internal battery. It is included with the device. There is also a light receiver on the face of the device that I assume contributes to managing battery power.

It uses wall current and can use batteries. Wall current should be your primary source as batteries don't last very long in this device.

Either. It can use batteries or use the ac adapter. We always use it plugged in but it does have battery option.

You can use either power source. It comes with an AC adapter. I purchased a separate battery pack for travel.

It's cable powered. By a too short cable in my opinion. Battery powered would be so great, but no... Primitive mind hasn't perfected so a glorious thing.

The power source has to be plugged into a wall outlet. You could possible retro fight a USB adapter if you know how...

I'd get a plug in one for that. Battery power pulled hairs and you don't want that.

It's battery or ac powered. Mine only was used about 6 times before it broke.

electric. pretty long cord, but we use an extension cord to get it to our field.

It can be powered by either. Don't waste your money on this product though. Very poorly made and breaks easily.

Battery? What battery? Mine is powered by DC but there is no battery. Just the 12v wiring in my motor home, like in an automobile.

Electric, I have a small portable generator that I use for tailgating. Machine works well.

No my friend, it is no battery powered, you need to connect it to electricity.

The other answers are correct. This needs to be plugged in to a power source.

Can connect to 110 electricity or use regular batteries. (Not rechargeable). Either works fine.

It is electric powered, with a rechargeable battery. I works great...very powerful and accurate..but our battery won't recahge anymore, so now we either have to buy a new battery or a new gun.
