Some comments on the HP charger:
* While no longer in production, the HP TouchPad charger is still very much for sale. I saw one just today for $28, and have purchased one myself for only $10 (on Amazon) as recently as last summer.
* With regard to the one report in the comments of a high-pitched whine, I can only guess that was a defective unit--I own 3 of these, and none of them make any noise.
* I also own several of the smaller HP Pre chargers--they have a lower amp output. If you're thinking of buying one, just get the TouchPad charger, instead.
