Got my PS 510 USBpass yesterday and it works unbelievably well, however, I've found that it will only work with one power adapter that I currently own(the infamous Kensington Model#KB8021US/K33396-which is more of a power pack then an adapter). The PT will not work with my computers USB port. It also immediately trips 2 AC/USB adapters I own(Both bought at Radio Shack- both 5V one rated at 500mA the other at 1A). I'm certain the reason is the PT is drawing to much current. I had a AC/USB rated at 2.0 A but it was defective and am awaiting a replacement.
I know Steve at PS is working on a list of adapters that will work with the PT, but I thought we all could help him out. If anyone has had success with a particular power adapter, list it on this thread, with model name and # as well as where you purchased it so others can gain from your experience. It may also be a good idea to mention what type of PT you're using(510, 901, 801) as the resistances and currents pulled are most likely different(although I could be wrong about that). Certainly all atty's have a slightly different resistance, therefore, circuit will pull a different current, therefore, an adapter one person may have had success with may not work for everyone else. But at least there will be a general list of adapters known to work for the majority of PT users.
Again, I have a 510 PS USBpass and I would like to add the Kensington Power Pack(Model#KB8021US/K33396) purchased at Best buy to the list.
Kensington - Battery Pack with Charger for Apple® iPod® and iPhone - 33396
It's also available on eBay and a myriad of other online retailers.
No dice for the kensington with me, worked for about 2 weeks, then nothing! Looking for a good replacement now.
