It needs batteries for the laser. If you just want to use the level adjustments then that requires no power

You can use either one. It comes with an adapter so you can use it without batteries.

Does not need batteries. Robust and reliable. I use it in conjunction with a laser unit to read surface and core temps.

It works without batteries. When you pierce the wire insulation, thats hiw it gets it's power. The alligator clamp opens and you place it on metal for ground. That nakes the connection for a circuut wich activates the light.

I'm not sure what your asking but i'll tell you this if you turn it on inside it lights everything up no need for a flashlight. You can see it as far as you can see very powerful laser I'm very happy with mine the rail under holds a flashlight so that's all I hope that helped if not ask in layman terms lol

2 sets of batteries came with it. Important to know that even when the laser is not on it seems to draw power from the batteries. I left them in and after a few days they were dead but the laser only fires briefly in response to 'firing'.

It doesn't take any batteries. It attaches to the gun and works off of the batteries that run the gun.

Yes batteries are included. You can also use the laser in any pistol. I use it in all of mine to practice drawing, sighting, etc.

Does not use batteries, you have to have it plugged into the electric outlet all the time.

I bought this lamp and it's definitely powered by batteries. There is no cord.

The laser works independently from the GPS. You do not need to turn on the GPS at all if you don't want to.

Does not require batteries. I used it in a low voltage application to turn on/off LED light strip. My power source was a 100-240V AC input to 12V DC output power adapter.

No batteries needed ! This is a great light, once charged it seems to last quite a while, then just re-charge. Throws a great light. Bought 1 for me, so impressed i bought 2 more for gifts.

No batteries. This is not an amplified device so therefore no batteries are used.
