Good idea for a post, unfortunately the "five best" really arn't up to snuff... all of these put out 5V USB voltage, and while some of them have good capacity (20Ah!) that's not actually all that impressive when you consider the voltage. I hate to say it, but lead acid gel-cells are still cheap, put out 12V and can be had in everything from 2Ah to 100Ah depending on the weight you want to carry.
Any recommended examples?
