Response and Results
This one would be used with the stock HP charger (to micro-female):good:
That should work and would have a lot less cable clutter than the original set up.
There is also one for sale that has a male USB connection for power instead of a female micro USB. With this it would be easier to hook to one of those portable USB chargers that use a full size USB port.

:good:
This one is best, as you say, for portable supplies with Std USB such as this one listed here :

I have a camera buff that wants to use that setup for DSLR, please return to post your configuration and results! :silly:
=== Review of Juiced Systems ACA adapter ===
I got this:
http://www.amazon.com/Samsung-Multi-functional-Connection-Kit-Compatible/dp/B006MJZOMW
It appears to be a USB OTG ACA compliant device. Sadly it's for Galaxy Nexus Products and the full ACA compatibility doesn't appear to be implemented in hardware and/or software on the Touchpad with CM9.
1- It does function as OTG host port with the Micro usb from a charger powering the down stream devices. :good:
2- OTG to devices on USB/microSD/SD interfaces works well, but only one at a time for memory volumes (FAT32). Not sure if that's a software shortcoming.
3- Success with a wireless adapter for Logitec mouse/keyboard on USB. :good:
4- Haven't found an NTFS mount solution for Touchpad w/ CM9 nightly 0903.
5- It does connect to the Touchpad, but not with the HP folio case or any case as it's a close fit.
6- The ACA charging of the touchpad while hosting, or otherwise, sadly doesn't work as it was reported to function on SG2.
7- ACA indicator never lights up for charging or host.
Initial Result:
- At $20USD there are fewer cables, but full ACA charging doesn't work, which was my motivation to spend more.
- OTG to devices on USB/microSD/SD interfaces works well, but only one at a time for memory volumes FAT32.
- The physical connection seems a little weak to me. I almost feel like it could break off damaging the adapter, or worst, the micro USB interface.
Further tests:
- I want to check if the Wirless mouse/keyboard on USB can be used with a SD card in either slot.
- I'd also like to test of external HUB with devices further downstream such as self powered HDD and seperate USB Mice, Keyboards (for deskside use).
- Can anyone recommend a ICS compliant USB GPS & app?
Although this setup with: Touchpad, USB battery, Juice adapter, is simple and elegant, its pricy for features I'm not able to use (charging while host). I'm not impressed it will be rugged enough for field use.
Here is my recommended portable solution, which is also cheaper:
- HP Touchpad
- Battery soulution of choice <<< $4.25USD
- OTG host cable & power Y combo:

- USB memory / flash drive of choice
(or other USB device that is ICS compatible with HP Touchpad)
