Hello leilaohu77:
In regard to your inquiry, I just wanted to let you know that the testing that Intel does on the stick is done under stock configurations using the components that came with the stick, so based on that there is not a battery brand or model that we can recommend for you to use it as mobile power (battery).
As an option you can try to use a 3000 mah or higher battery charger in order to be able to charge the stick.
Any questions, please let me know.
Alberto
