Just did this to my iron a few days ago, then saw this. I didn't do the drill thing, just cut a small slot in one end of the battery cap. Works great, used it for over an hour with no problems. I have a standard plug in soldering that has two voltages to do any heavy duty soldering. (20amps & 40amps)

What all could you solder with this? It doesn't seem like it would be all that powerful.

Will the USB port handle soldering iron? I heard that battery powered soldering irons consume currents over 1 amp and USB ports can supply max 500mA. Am I wrong here?

sorry about that, must have got it mixed up with something else, but the maximum current does increase when the two data lines are joined- that would probably explain the confusion as to whether the limit is 100 or 500.

I thought max available current from a usb port was 100mA...
Jun 10, 2010. 9:40 PMeight says:
Nope. 500mA

I said the 'maxmium' of 500mA, normaly it would be lower.
Jun 7, 2010. 6:40 AMThe Skinnerz says:
I have seen on some USB sockets that joining the two data lines together allows more current to be drawn, giving more heat. up to 1.5A, instead of the usual 1A.

why would you want to take a cordless soldering iron and make it into a corded that you can only use around USB ports?
Jun 6, 2010. 6:28 AMagis68 says:
hahahah.....exactly, I searched all the world to find this wireless soldering iron (is really the best tool after my dremel) and make it wired??? What reason? Meaningless Instructable or acceptable if I take as a joke! Go wireless dude!!!

Sounds like the haters shall not be satisfied until you make the device either battery OR usb-powered.

ok that is you but if i had a battery powered soldering iron i would keep it as is cause i would use it a lot more that a corded one

Nice idea, but won't it be better if the USB port could be used to recharge the batteries? It seems dangerous to me to solder around my computer, imagine molten solder ruining your 200$ monitor. Probability a good idea to cover it with a peace of cloth when your using the iron. Better safe than sorry!

Great idea! I have the same iron, it's a piece of junk. I'm going to do try this with mine.

i was thinking of doing this to mine, but am worried about drawing too much juice thru the usb and dammaging it (the mobo) :S

Use a USB hub if your that worried but as godofal said, it won't do any harm.
Jun 4, 2010. 12:08 AMgodofal says:
damaging what? the soldering iron or the USB port? you can put in rechargable batteries that have more than 2500MaH current each, wich is ALOT more than USB can provide. as for the USB hub, it cant draw more than 500MaH there, on most (nearly any) PC there's a protection against that...
