Thanko is back with their whacky USB Soldering Iron, letting you use it with a 9V battery for all your DIY electronic projects. It is capable of heating up the iron to 500 Celsius, so do be careful with this on your desk! Of course, when plugged into a USB port, it reaches around 200 Celsius (300 if you’re using a couple of USB ports). Expect a $28 price point thereabouts for this from Thanko.
