I've got my new TS100 soldering iron and it is amazing. It arrives in this nice cardboard glossy box. Inside we have the main unit, a solderiong tip, manual, iron stand and the earth cable.
You could power this iron with a battery or directly a power supply with voltages from 12 to 24 volts and you will have an output of up to 70W. After unbox, I've inserted the tip into the main unit, connected a 14V battery and power it on. Then after pressing one button, the temperature got up. I set the desired temperature and could start soldering...
