Review on [2 PACK] 3FT 12V Female Socket Battery Eyelet Ring Terminal 12volt Extension Cord Outlet Adapter Plug Power Supply Car Electrical Dc Charger Accessory Connector Kit 10Fuse - Reliable Car Power Supply Kit with Dual Female Socket Terminal by Gerson Lagerquist

I have a ham radio transceiver that I usually use in my truck. I want to use it in the field and run it off a 12 volt battery. The radio only has a cigarette lighter plug so I had to adapt it to the terminal blocks on my battery box. These adapters are used here (see photo). I love the fact that the rings on the ends are big enough to fit the 5/16" terminal blocks on my battery box. Ring terminals are securely attached to the cables. I also like the built-in fuse to protect the battery and the radio from short circuits. These are high quality cigarette lighter power adapters that can be used to power any cigarette lighter powered device directly from a 12v battery or battery box. I recommend them.
