That is what I do, but mostly just to charge the phone. My GPS and camera both use AA batteries. I carry a few spares, and buy more along the way. Never tried to ride with a laptop. Travelling by motorcycle/scooter has always been kind of a primitive experience for me, that's where most of the fun is. Even the phone (regular cell phone, not a smartphone) and a basic GPS (not the kind with maps) already kind of takes away from that.
