Super Boost charging my phone off of two AA batteries.

I think that is enough update posts for right now.

I designed a 3D printed case for the Super Boost. It has two parts and is designed to hold two cylindrical 18650 lithium cells.

So I just finished building my first Super Boost. It converts 2.2V – 4.5V to a steady 5V source. This is perfect for charging a cell phone or any other device that charges via USB by using 2 AA batteries or a single cell lithium battery.

The project page is here and the DIY page on assembly is here.

Going to solder one together tonight.

Taking some suggestions from some members over at Dangerous Prototypes and Abdullah Kahraman I redid part of the Super Boost board to create V1.1. I updated the Super Boost Page to reflect this.

Thanks for the help everyone!

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

Order boards in the morning.

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.
