COOLM 2PCS 5.5mm x 2.1mm Female to 3.5mm x 1.35mm Male Plug Socket DC Power Adapter Cable

Loved this dc adapter. I used it to connect my solar panel output to my new lithium battery input. It works perfectly

The small end fits perfectly into my Icom ID-52, letting me charge it from any 12v adapter that has a 5.5x2.1mm coaxial connector. Good quality. The flexible portion reduces the strain on the jack in the side of the radio.

I used these to adapt a 5.5mm barrel connector to work on an Atari Lynx. Worked great!

Does what I needed them do. Using them as an adapter for solar charging a battery generator.

Works great. Use it to connect a 6 volt battery & solar charger to game camera to entend battery life.. make sure you check size on the game camera.
