MacBook Battery Charger/Conditioner

What would be even better is a "battery charge adapter" - small device with MagSafe-comaptible connector on one end, battery-compatible connector on the other end...

That way, if you have 2 batteries, you can use one in your MacBook and be mobile, while charging the other one directly with your MacBook AC adapter via this "battery charge adapter"!

@Brian:

sure, but if, for example, you're on a plane and you don't have access to a power point, having an extra battery or two is always handy.

This is good because it means you can charge 2 batteries in the time it takes to charge 1, and you'll have twice as much power when you're on the plane.

Great Idea . . . .they should make a backpack version with a solar adapter so that you can charge in your bag as well . . . . i hate trying to find a plug at the local coffee shop only to have people trip over it

Dave, see the PowerBook G3 (Pismo), its bays even support fastmac's blue-ray drive you dolt

I don't see what so great about this. Why do you need a battery charger if the laptop charges it, and if your battery power is low, didn't your macbook/macbookpro come with a power cable?

Dave,

I can order a laptop with 2 batteries inside the machine?!? or 2 optical drives with no battery. Please, show me those build to order options on Apple's site. Just because you don't find a need for something, doesn't mean it isn't useful to other people. Yes I know machines are thinner, lighter etc. now because of no more swap-bays, doesn't reduce the need.

@required you miss hot swappable gays of yesteryears pc notebooks. Nobody uses those anymore, didn't you get the right part in the computer to begin with?

I miss the swappable bays of yesteryears powerbooks

@6,
you would think that having just bought an extra battery would make this even more useful becuase you could charge one while you use the the other.

I was just wondering why Apple didn't have something like this available...not sure if I can invest another $150 for it (since I just bought another MacBook battery) but definitely tempting.
