I was thinking about getting one of these:

My question is, if I get 3 sets of rechargeable batteries and just keep rotating them , will I always have a fresh set?

Now that is a device I could really use! Do they sell it at Wall-mart?

Naivetek. Sounds like a reputable brand name to me!

I don't think so.

Come on Clararhb, no wet blankets here. This may be the invention of the century!

Maybe the decade, but not the century

I have never heard of this, but here is the explanation:

Credit cards work this way too don't they? Just use the larger one to charge the smaller one.

And what about scuba tanks? What if we had a smaller tank we could charge off our full sized one?

It's done all the time, using a transfill whip to fill smaller LP tanks from a large HP tank. Handy when you're on a small boat with no compressor on board and want to squeak out another dive.

I've never done it, but I know a number of people that do it nearly every time they go out.

That battery charger is hilarious, though!

No more fumbling with that pesky power cord. Genius!
