I really wanted to use my passthrough at my favorite TV watching chair and in my car, so I purchased an AC/USB converter and a car USB converter from HDMI cables, DVI cables, HDMI wall plates and HDMI switches. (known as ebuyHD.com) because they were REALLY CHEAP ($2.82 & 1.78); and now I know why. The AC/USB converter never worked, and the car converter just fried my favorite atomizer from EcigMall.
Sometimes you really do get what you pay for. I got another AC/USB converter from Radio Shack for about $15.00 and it works great. If you know of a car/USB that works well please let me know.
