  • Convert a battery powered LED lamp to USB power.

    Awesome! The cable I chose turned out to be a "charge only" cable, so it was even simpler.Didn't want to remove the battery functionality of the light (actually it's a small Christmas tree!) so I just attached the red and black to the pos/neg battery terminals respectively, and it allowed me to keep the switch.Not a permanent (or professional) job, but it works like a charm!
