Griffin Technology (http://www.griffintechnology.com) has announced their latest car charging solutions, updated to the 2.1 amp charging level required by iPad: PowerJolt Plus, PowerJolt Micro and PowerJolt SE.

You plug the US$29.99 PowerJolt Plus into your 12-volt socket and connect its coiled dock cable to your iPad. While it’s charging, it pops open to reveal another 12-volt accessory socket, built right in. You can charge and power your GPS, mobile phone and more; you won’t have to unplug PowerJolt to regain the use of the socket.

The $24.99 PowerJolt Micro’s DC charger delivers 2.1 amps of power. You can use it to charge from almost any vehicle’s 12-volt accessory socket. The detachable dock cable can be used separately to charge and sync your iPad, iPhone or iPod. You can use it with other devices, too; use the cable that comes with your device and plug it in PowerJolt’s USB port.

Plug the PowerJolt SE ($24.99) into the 12-volt accessory socket in your car’s dashboard or console and charge your iPad, iPhone or iPod while you travel. An LED ring lights up to show that PowerJolt is receiving power and is ready to charge.

Griffin also announced general availability of its PowerDuo for iPad, a $39.99 combination pack containing 2.1 amp charging versions of both PowerBlock and PowerJolt for iPad.
