If I where to design this product the ratio would be reversed. I’d create a 3 USB port adaptor with one cigarette plug. After all, I only need one car frig to keep my beer cold at the baseball games. But I do have an MP3 player, phone and camera I’d like to charge up while on the drive over.
The Brando 3-in-1 car adapter with USB port is definitely a good idea. There have been several occasions where I’ve wanted one.
UberGizmo brings up a good point – it might not be the best idea to daisy chain some USB hubs off the single port to power everything you’ve got. Might strain the car battery too much over a long period of time, none-the-less, an excellent item to have for those long hauls.
Brando has them for $20 and ships to the US (and globally) very quickly and inexpensive.
