This my device and I am using it as a cell phone charger. I tested its current and voltage during charging my NOKIA cell phone and got 6V and 700mA output. I think 5V and around 450mA output is more better for charging Li-ion cell for its long life. So I want to decrease its output to 5V, 450mA. Which components should I have to modify here. I guessed R1 (5 ohms, 2W) is responsible here. I didn't replaced and didn't measured because everytime if I replace components I damage the board (copper tracks) due to lack of desoldering devices!
