Make a USB phone charger for almost any cell phone!

Step 4 Ta Da!

You should be done! Plug your altoids tin into your computer (if it doesn't fit, simple run a USB extender cable (1 male end w/ a female on the other) from the tin to your comp. The LED should light up, if not, flip the power switch. If the LED still doesn't turn on, then you did something wrong. If it lights up when you turn on the switch, plug it into your phone. If your phone doesn't reply like it should, quickly disconnect it and back track.

Not with an iPhone 3Gs or 4. On those phones, the USB data pins need to have a voltage on them. D- should be 2.0V and D+ 2.9V to make the phone charge in high speed. If your wall wart is less than 800mA, you may want to have the phone charge in low-speed mode, with both pins at 2.0V. Ladyada, maker of the mintyboost, goes over this nicely.
