google 'laptop battery power supplies', are you wanting a battery supply?? because shipping regulations for LiPol and lion batteries have changed in the last 6 months and its more difficult/impossible to import them.
Thanks for the reply qusp. What I'm looking for is to charge up the 9 volt battery in the Meier XXS amp. Like I said, the only ones I can find are the size of bricks, and I want something small to take away with me when I visit my kids.
