Scoshe just announced the reVOLT 12W + 12W Dual USB Car Charger for iPod, iPhone and iPad (12 Watts x 2 Ports) for $24.99 + $5 shipping.
reVOLT is the world’s smallest yet most powerful car charger for USB powered devices. Each of the 2USB ports packs 12 Watts (2.4A) of power to quickly charge two iPads at once.
The latest iPads have been designed to charge at 12 Watts, making reVOLT the ideal charger for these devices. Optimized charging circuitry will not cause any harm to less powerful devices – iPhones and iPods will also charge at the fastest speeds possible.
