Insulated Alligator Clip 20A
Standard alligator clips. Fully insulated. Black vinyl insulators cover the entire unit except for the tip. If you tinker with electronics you probably already know how handy these are, especially to connect to power sources.
The insulation can easily be removed to solder a wire to it. We solder a clip to each side of a wire to make it useful to connect to almost anything requiring power.
