Well, I was interested in getting a 2nd round barrel plug to 24 pin adapter, and now I have lost my original adapter. This means that all I have to charge my 210 is the sync cable (which I leave at my office desk) and a 110v to USB adapter plug that I attach a USB "A" to mini USB cable to (but that is slow charging). The good new is that I have found where I can buy a replacement adapter:

My other option is to purchase an after market charge and sync cable on ebay for around $10 with shipping, or the original OEM cable from HP for $20 (they also sell a sync cable that is just the USB "A" to mini USB cable for $20--what a rip off). The other option is to get the enhanced sync/chargine USB cable that includes the USB host plug for $50. I don't think that I'll do this since I never once used the USB host on my Pocket Loox 720 in the 3 years or so that I had that device.
I'll probably go cheap and get the after-market sync cable on ebay. I can't see it, but the description says you need to plug in your power chord for charging, so it must do the round barrel plug to 24 pin adaptation.
