Rechargeable USB Blue Laser Pointer 1600mW with 26650 Battery

Although this is a class 4 laser pointer, it only uses one battery, and the battery is Panasonic (long battery life).

This thing is larger than a regular laser pointer, with high power and rechargeable function.

It can be good or bad, depending on what you want it for. It has a powerful and wide laser beam, and the rechargeable function is great.
