Thought I'd alert those of you who might be interested in one of these. I have had the Gomadic AA charger with the tip for the Kindle for several months and last night I finally had occasion to need to use it. I'm on a business trip in an older hotel with no spare power outlets near the bed, so I pulled this out to use it, as I was minutes away from a dead battery. I discovered almost immediately that the tip pulls out easily (far more easily than the regular charger) and even when it's plugged in, it's a bit loose in the jack. That means it's not necessarily seated at just the right angle to actually turn on the light to indicate that it's charging. So beware. I decided it will work if I can set the Kindle on a table with something pushed against the charger to keep it at the right spot but it's useless for use while trying to read - and really, what's the point of putting the Kindle down? So while better than nothing, it's not quite as useful as I had hoped it would be.
