[Tilt, TyTN II, MDA Vario III Accessories] Facegarden:
A couple of things:

As far as USB port power goes, I've read up about this (forget why), but the USB spec DOES say that each USB port needs to supply at least 500mA... But in practice motherboard manufacturers tie the power lines of multiple ports together, so if a motherboard has 4 ports, the power bus will be connected to all of them, and it will supply at least 500mA x4, or 2000mA (2 Amps) total. There is generally no individual regulation of this however, so if you only have one device plugged in, it has the full 2 amps to draw from. Often other devices like mice or keyboards use so little power that there is plenty left for other peripherals to use well over 500mA even when all the ports are in use. This is actually a problem, as many product manufacturers get "lazy" and design products that actually NEED more than 500mA, especially things like bus powered hard drives, because those work on most systems (but frustratingly, not all).

As far as power supplies, i got curious, and here's what i found:

The exact power supply that comes with the tilt is about $8US from mouser in the US:

it's mouser part number: 552-PSA-A05A-050-R

Sadly it doesn't fold and it also only provides 1A, so, here's some more stuff:

This part is similar but just has a USB port on it, so if you already have the data cable with you, the AC adapter won't take up much more space:

Now i'm really not having any luck finding exactly what you need, but if you're a bit handy you can wire a mini USB port onto another 5v power supply with more current output. I can't tell you which wires go where but if you have a multimeter and a soldering gun you should be able to figure it out:

here's a USB mini cable with wires coming off one end if you don't want to cut up a cable you already have: http://www.digikey.com/scripts/US/DKSUS.dll?Detail?name=WM17104-ND

And any good regulated or switching 5v power supply should be good. Here's one with 2A output, and it's described as "flip out", so i imagine the connector, um, flips out, but it's not a stock part so you'd have to call them, and i don't know if it's regulated or switching (either is good, i think), so you should ask: http://www.digikey.com/scripts/US/DKSUS.dll?Detail?name=T321-P5P-ND

an in stock, non-flip out one is here:

If you custom wire one, test it on a less important device, just to make sure that it really will be okay, and don't sue me if it breaks something. ;) Plus, i don't know how the kaiser feels about charging at more than 1A, since the stock power supply only provides that much current.

Also, another kind of plug is the "multi-plug" power supply, with removable plugs to allow for plugs from different countries to clip on, so rather than flipping out the plug, you could just unclip it, if you don't mind having 2 pieces. Here's one of those at 1.2A and $13US: http://www.digikey.com/scripts/US/DKSUS.dll?Detail?name=T946-P5P-ND

or 3.2A at $18US:

But you might want to call HTC and talk to an engineer (they're hard to get a hold of, but i've been able to do it at other companies if you keep asking) and make sure that higher charging currents are okay.

And i really only checked mouser and digikey for these things, so it's possible that other suppliers might have something different, though they are two of the largest suppliers of this kind of thing in the US, so i'd be surprised.

You could even call CUI direct and speak to someone there, they're nice people and they might be able to make you a custom one for not too much (i doubt they'd do that for one unit, but if they already make something close they might!).

If you can't get what you need easily, try harder! Hehe.
