A portable charger that you're referring to is generally going to be of very low capacity. You'd be lucky to get a 30-40% boost in battery from these types of external chargers.

Thanks for your input!
Not true. There are plenty of 10,000mah+ external batteries in the $30-40 range on Amazon. As someone said, this service won't make you much money. That'd easily give me 7-10 charges on my iPhone.
