Whether you are traveling for business or pleasure, the last thing that you want to see happen is your iPod or iPhone run out of battery. This leaves you without possibly your primary source of entertainment, Internet access, and communication. It’s not always feasible to find an available wall outlet and sit there for hours on end as you wait for your iPhone to get some more juice.

This is where the creative minds at Griffin Technology come into play, providing us with the PowerDuo Reserve. This product is really comprised of three separate but related components, all of which will come in handy during your travels.

First, there is a PowerBlock that can transform any available AC wall outlet into a powered USB port. This way, you can charge anything that would normally get its power through a USB port, like certain digital cameras, media players, and cell phones. Second, there is the PowerJolt that transforms your car’s 12V outlet (the cigarette jack) into a powered USB port. If you’re going on an extended road trip, this means that you can keep your USB devices fully charged while on the go.

The third and possibly most important component is the portable power pack that gives the PowerDuo Reserve its name. This reserve battery attaches magnetically to either the wall outlet-based PowerBlock or the 12V outlet-based PowerJolt, charging its internal battery while still allowing access to the USB outlet for other devices. This reserve battery can then be detached and attached to your iPhone or iPod, giving it a bump in power as needed.

The Griffin PowerDuo Reserve is currently listed at US$59.99.
