Best way to charge battery outside of phone without external charger?

so far ive been trying to charge my battery outside of my phone without an external charger and the only good way ive found is very painful... basically what i do is use a cut usb cable and connect the red wire to the positive and the black to negative... but i have to hold it in place with my thumb and it burns me... bad. so please help. btw ive tried electrical tape but it wont stay in place. is there any way i could make a makeshift charger with a cut usb cable?

I believe your best bet would be just to get an external charger. They have all sorts of them on Amazon, for example, that are really reasonable.

I'm afraid you are going to either hurt yourself, worse than the burns, or short out your equipment. :(

Neither one of them would be a good thing! :)

Wow that is an incredibly bad idea! Li-ion batteries just can't be hooked to voltage like that for charging. They require a smart charger (your phone handles that). You are lucky not to have blown up the battery or have a total meltdown..

Why can't you just charge it in the phone?

I thought this was some kind of joke when I read the title. Now I've read the thread and I still can't tell.

Tell us why you can't use an external charger either?

This thread just Made My Day. I would have held the wires in place with my tounge. "trialnerror", right?
Do you have a Bestbuy or Radioshack nearby?

You can get a usb sync charger of ebay for as low as $3 dollars.

You're literally playing with a potential fire.

When batteries ignite they don't burn like a Zippo, they jet a flame like a blowtorch.

yeah believe me i know... and im also a pyromaniac... but thats besides the point. theres not enough voltage on an xbox usb port to ignite a battery
