When you're on the road, a fully charged BlackBerry® smartphone is more than a convenience - it's a necessity. And now it's easier than ever to keep your smartphone fully charged, virtually wherever you go.. Just plug the BlackBerry® Micro-USB Vehicle Power Adapter into your car's power adaptor ("cigarette lighter") and, like other BlackBerry smartphone chargers, it charges your smartphone rapidly, and helps preserve the life of your battery. Then tuck it away in your glove compartment or door pocket until next time. It comes with a coiled 30-centimetre cord that stretches up to two meters for your convenience in any production vehicle. It's even micro-USB compatible.
