You see people online selling small DC brushed motors as generators. I just ran tests on some DC motors from RO water filter pumps, so I used a similar setup to test these small motors for efficiency. Can they be used to charge cell phones or batteries? Will they work for rain gutter generators or small wind generators? You decide.
WARNING: Working with motors and electricity always carry some risk of injury, burns, fire, shock, and electrocution. If you do not know, learn first or do not do it.
