The Smallest and the Brightest Flashlight Ever!

this is our new helper for camping,mountain climbing,reading and sailing.it's also very cheap and it costs under a dollar.

1-1w power led

2-3.7V 350mA li-ion battery

3-li-ion battery charger board(optional)

4-power led lens and holder(5^ or 45^)

5-small on\off switch

then add the lens and hot glue all the thing together.

now you are done and you can test the flashlight as i tested the battery will last about an hour so it's good for the size of it.
