It seems like portable chargers are getting smaller, cheaper, and larger capacity all the time. What better example of this phenomenon than this Omaker external battery, which boasts 15,600 mAh and two USB output ports that push 2.1A, the amperage needed to charge tablets and some phones at faster than a snail's pace. The device itself supports 2.1A input too, so it should refuel reasonably quickly once you've drained it.
For reference, the new Samsung Galaxy S6 will have a 2550 mAh battery.
