How many different devices do you power with your car’s cigarette lighter? Now how many of those use a USB cable to draw power? It’s very likely that many of them do indeed use USB, which means having such a port in your car is convenient. I’ve had a couple of different adapters over the years, but they don’t always provide enough power (especially for an iPad), and they are almost always bulky.
Griffin knows what’s good, as they’ve released their PowerJolt Micro, which is a very simple USB adapter for your car. The nice thing is that not only does it provide the necessary juice for an iPad, but the port will actually sit almost flush with the cigarette adapter. No more worrying about bumping and breaking a bulky adapter. For $30, I’d say this is a must-have for the car.
