Here once again an elegant and practical new solution by the people at Incase.
“Incase is the first to offer a 2-in-1 iPod and iPhone charger that is both AV and DC compatible. Designed for both wall and car sockets, the charger combines function and economy with dependability. From home, to the car, to the office, the 2-in-1 Wall & Car Charger keeps your iPod or iPhone charged no matter your location.”
For 39.95 USD, it’s also well worth it!
