Griffin’s latest contribution to the mobile world comes in the form of a couple portable charger/external
battery solutions for the iPhone and iPhone 3G (iPods, too). The PowerBlock lineup from Griffin includes the PowerBlock Reserve and PowerBlock Jolt. The PowerBlock reserve is tailored for use in the home or office, while the PowerBlock Jolt is designed to give you portable power in your car.
Both the PowerBlock Jolt and Reserve sport a removable Li-ion battery pack that’s good for an additional 6 hours of iPhone-uptime on a full charge. The PowerBlock unit charges the battery pack through a wall outlet (for the PowerBlock Reserve) or through a car’s cigarette lighter port (for the PowerBlock Jolt). And, because outlets and power ports are sometimes scarce, Griffin has designed their PowerBlocks with USB ports that you can use to charge your iPhone or iPhone 3G through the PowerBlock.
Once charged, the removable battery pack plugs directly into your iPhone for a quick top-off or a much-needed recharge. Think of the PowerBlock as a replacement for the Apple iPhone charging block, but it sports an external battery pack to make your life easier.
The PowerBlock Reserve (the wall-charger variant) and PowerBlock Jolt will be available from Griffin in April for $39.99.
