Looking for a power pack that is portable first off. Not one of those bulky things that needs to be carried around by hand but rather can be just thrown into a backpack. Also One that I can power a laptop or any other device. Ive been able to see the USB ones but I also have a Sony Tablet where it has a special plug. I dont know if one exists but one that has the ability to have a AC cord plugged into it. Or buy another converter that can convert AC plug to USB plug which could then go into a USB accessible power pack.
I know this is being hopeful but hopefully someone has some insight or experience with such devices.
Thanks.
