3" RCA "Y" Adapter

I just purchased a 12 Volt/USB Powered Heated Travel Mug from your site and was more than impressed with the speed of delivery and quality of the product. I never write testimonials, but in this case I'm making an exception! The USB powering ended up being far more useful than I imagined it would as I can now keep my coffee warm in the office too! Thank's again. Steve K. — Dallas, TX —
