Rechargeable Weedeater Trimmer Solar Hack

About: You may recognize Dan and Denise Rojas from their appearances in various made for tv movies and national commercials. As the hosts of Green Power Science, they share Fresnel lens and alternative energy ideas...

All brands of rechargeable trimmers have a battery life issue because they need to remain lightweight. Over time the charge controller board does not allow for a good deep battery charge so they only last a minute. You can find them at yard sales all the time. If you have a spare panel with MC connectors this is a fun easy fix. An external charge controller (not shown) can be added for quick solar charges needed in heavily shaded areas. You can use up to a 50 ft extension cord before voltage becomes a problem. Great solution for larger yards far from power. No more burning up electric AC trimmers with 200 ft of cord. I guess you could use a gas trimmer but the exhaust is very bad for you.

    I really want to try this. But I am having a hard time believing this works. I cannot help but have the feeling that there is a battery involved and that the panel is just charging the battery. If not, I am curious to know what the voltage output from the panel is. I am assuming somewhere around 18V. I appreciate the video, but I really wish this was a step-by-step tutorial.
