PCB is routed on a single sided PCB. How about them apples.

This design is inspired by the Minty Boost but it fixes some of the issues in that design. The Minty Boost is limited to 600mA due to the LT1302 chip. The Super Boost uses the LM2700 which can push up to 3.6A. This will enable iPhones to charge much more quickly.
Charging more quickly will drain and reduce the life span of AA batteries so lithium batteries are the ideal source.
