One annoyance with carrying around spare laptop batteries is trying to figure out a speedy way of charging the suckers. This is doubly true for Mac laptops, where the only solution is to slot a new battery in and charge it until its full. There’s simply never been any other way of doing it until now.
The FastMac TruePower U-Charge offers a solution. With a kit full of tips and connections for Mac batteries both modern and antiquated, you can charge your spare batteries without plugging them into your laptop first… halving the time it takes you to charge more than one battery hours before a flight. I’ve been looking for something like this for awhile, but I’m not sure it’s worth the $70 they are asking. Convenience is only worth so much.

$70 really seems like too much for what you are getting. But this would be very useful for me, I’m usually carrying 3 laptop batteries with me since I’m traveling with my job a lot. And even 3 isn’t enough sometimes. This cable could be a life saver.
