I use them to charge my two cameras and they work great. I have a solar panel with a micro USB cable as the only output, I use it along with a micro USB splitter to charge the batteries in my outdoor cameras. It works great; Both my cameras stay charged. I wrapped tape around the joints to make it waterproof. I don't know if that's necessary, but I'd rather play it safe. I'm looking for a better solution but for now it protects them from the elements. Will be updated if something happens with the cables.
