Glove Box Gadget Mini Cellphone Charger
Here's a instructible I put together that is very handy and portable. Also going to post it to the contest glovebox gadgets because that's where I keep mine for emergency. If I forget to plug my phone in while on the road and I have to stop in somewhere for awhile I'll take it and my cable drop the charger in my pocket my phone in its case plug it in turn it on and it charges as I go and do and can still use it while charging. Hope you enjoy it so vote for and any questions or comments feel free to ask. Thanks for looking.

Step 1: Material

I purchased this neat little device called a dc to dc step up converter. In practical terms it's just a dc low input to high output power module.

It's a 1.5 volt dc to 5 volts dc at 1.2amps usb.

Step 2: Materials Also

Here is a AAA battery holder with a on off switch for power to the dc to dc module.

Step 3: More Materials

Heat shrink.
This is a piece of tubing that when heat applied it shrinks. Works mostly for electronics but I used it on many other applications. Such as on frayed shoe laces or to make something round to fit in a larger space.

Step 4: Even More Materials

Here are 2 of the main things needed for this instructibles. A soldering iron and resin core solder. I prefer resin core for the purpose the flux is already in the center of the solder. Works great on a clean surface not to great on a dirty surface until the surface heats up. The soldering iron is a 20 watt for small jobs.

Step 5: Even More Materials Than Before

Here are the other tools used for easier wire cutting and stripping. You can also use a knife and fingernail clippers for cutting and stripping wire just be careful though.

Step 6: The Few Bits And Pieces Of Parts Needed

Step 7: Finished Product

Here are a few pics of the finished product.
Not very hard to make but have to be pretty quick and precise to not get things to hot and not take to long because the chips and circuits can melt or shorten out if they get to hot.
On the module is a negative and positive terminal. Solder the red wire to the positive terminal and the black wire to the negative terminal. I used the heat shrink to cover the module to protect it from be shorted out by metal parts or anything that can get the circuits on the board. It also works as somewhere glue epoxy or whatever you want to use to mount it to the battery holder. I used crazy glue.
