Backup battery compatible with the Prime - Asus Eee Pad Transformer Prime

Does anyone know of a backup battery that will charge the prime on the Go? I have one for my phone but it only outputs 5V.

I didn't want to have to get it yet. I was holding out to see if it became necessary.

Because it not a regular micro USB port finding another power alternative won't be easy

Try this for a battery backup solution, then all you need is the cable that comes with the wall wart...

Thanks for the suggestion but apparently the prime will only charge with 12V or greater and this only puts out 5v. I have one of these in the 5000mah version for my phone, works exceptionally well but it won't charge the Prime, unfortunatly.

I use this:

for the wife's iPad and from what I can tell it would work for my Prime as well. I may have to get another one for me.

I like that phone suit, it's not bad looking, but I have no idea how I'd get the Prime hooked to it to charge especially since it needs their own special plug.
What I'm wondering is why did Asus choose to go with a 3cell lithium ion battery (12.6V charged) when it looks like the other tabs are using a 1 cell (4.2V) like the phones use.

The PhoneSuit has a USB plug on it for the 12V out, so you can use the Asus power cord.
