Change a normal 9v battery into a life saver. If you have ever run out of juice on your phone and could really use a quick charge then you need a USB battery.

Shopping list:
1 5.1v zener diode
1 330-ohm resistor
1 9v battery connector
1 9v battery
solder and soldering iron
(you can get all of this at radio shack)
Instructions:
1. Solder the Zener diode to the left and right USB connector prongs.
2. Solder the black wire of the 9v connector to the left prong and the right wire to the resistor.
3. solder the other end of the resistor to the right prong.
4. Hook up battery and go to town.

Household Hacker = We do videos so we can see how many stupids actually attempt to make it.

[mustwhatch]

btw i know how to put it together becuase i mess with electronics all the time but if your not clear in your vid then people will mess up there phones or what ever they charge i know if i was a little kid and i messed up my iphone i would be p off and wouldnt pay any attintion to anything you ever post again like i said not trying to be rude im just lookin out for little kids and your rep

[mustwhatch]

hello is there a spicific way that the diode and resistor are supposed to be and if not why couldint you just say the resistor goes to the possitive side and the diode goes to the negitive side instead of saying left and right it looks like in the video you striped all but the positve and negitive wires away im not trying to be rude but if your going to make these videos be more spicific on how to do it i know you have a disclaimer but you know people are going to try it especialy little kids

@oj1997ss All the electrical engineers that edit the Wikipedia pages make the learning a bit difficult. Seems like an interesting field though, so I'll keep going.

@iamenjoi As would rubber gloves and a rubber mat I suppose. I'm wanting to learn; I don't plan on jumping right into experimentation.

@applesauceis22 I'm a Nuclear Electricians Mate for the United states navy. DO NOT ATTEMPT THIS! if a short or an open were to happen, you would be fucked.

Attaching a fuse somewhere in the schematics would help.

Gonna hit the drawing board.
