I gave the plug 5 stars because I needed it to temporarily keep my cooler working and to allow me to cook or heat up food in my truck til I got to peterbilt to get 3 cigarette lighter plugs fixed. I've had my coleman cooler plugged in since 10/21/19. I unplugged it for about an hour last night 10/25/19 to plug in my burton cooker. I plugged the cooler back in and so far so good. So damn glad to have this f'n cord.
