9v Altoid USB Charger





Introduction: 9v Altoid USB Charger

Just one more 9v USB charger!

Step 1: Materials

- Altoid tin
- 5v regulator
- Wire
- Small LED
- Soldier
- Female USB
- Epoxy (i used J.B. Weld)
- Small slide switch
- Tape

Step 2: Perpare the Tin

Trace the outline of the USB on the bottom of the tin near the edge. Mark the spot where you want to put the LED. Drill it out with a drill bit slightly larger than the led. Use a drimmal to cut out the hole for the USB. Sand the surface smooth with sand paper then use a smaller girt to polish it.

Step 3: The Circuit

The circuit is very simple. The usb has 4 pins you will only use the 1st and 4th one. The regulator has 3 pins the 1st one is the ground the 2nd one it out and the 3rd one is in. Now follow the diagram.

Step 4: Assembly

Now tape around the usb near the bottom so the glue wont get in side it. tape the hole on the tin on the out side. as shown in the previous picture. Stick the usb in the hole then mix up your epoxy.spread it all around the usb. Wait till it drys then glue the LED in the hole too.

Step 5: Finshed

This is the finished product!

    Most smart phone batteries are 1500-3300mah.

    A 9V battery has 50-400mah and at 500mw load has less than 300mah capacity.

    You're also losing 30% of that 300mah thru the 7805 as heat.

    Just exactly HOW much does this remaining 210mah charge your phone ???

    Ref : http://www.powerstream.com/9V-Alkaline-tests.htm

    is also for ipod touch 4g

    Also, for most iphones the middle two connections need to have 2V running to them for it to "recognize" it as a charging device.

    Diode is essential. Without it it can drain your phone's battery. Found this out the hard way.
