Introduction: Increase Battery Capacity of Solar LED Flashlight Phone Charger

About: I am always hacking computers, Ipods, phones, random electronic devices and most of all, life. I enjoy observing the patterns in everything and exploring life and this planet.
This guide will explain how to drastically increase your charging capacity for your Solar LED Flashlight Phone Charger Emergency Dynamo Crank and build a 3 way adapter

NOTE OF CAUTION - DUE TO THE NATURE OF THIS MOD IT COULD POTENTIALLY DAMAGE YOUR DEVICE, BY READING THIS YOU ACKNOWLEDGED THIS - I have never had this happen running up to a 1500ma battery but the danger still exists

Required Parts:
Solar LED Flashlight Phone Charger Emergency Dynamo Crank
Soldering Iron + Solder
3.7v battery with a greater capacity than 330ma
Small Phillips Head Screwdriver
MicroUSB to USB cable (used to charge almost all smartphones)

Issue #1 - Lack of a microUSB adapter
-Building a: USB -> Charger IN/OUT <- MicroUSB
Issue #2 - The tiny 330ma capacity battery
-Replacing the battery

Step 1: Disassembling the Device

For the battery I am using a 3.7v 1130ma Lithium Ion battery that I took from an android phone.
Step 1 - Go ahead and open up your device by removing the screws (4) in the corners; try to do it slowly as to keep your buttons from falling out.

Step 2: Prepping the Batteries

Step 3 - Prep your replacement battery by scratching up the contacts (use a screwdriver), this allows for a proper solder bond

Step 3: Switch the Batteries

Unsolder the two wires from the terminal on the board as it's a good idea to increase the gauge of the wire
Then solder the new wires to the new battery

Step 4: Test and Reassembly

Test the device by connecting it to a power source, if charge light appears and stays on for an extended period then you can call it a success.
