Thanko - Handy USB soldering pen
With Thanko's new 8W USB soldering pen, if there is a USB port around you, you can solder anytime. When you bring a mobile battery with you, seriously you can get your soldering work done anywhere, anytime.
You are ready to use it after connecting the USB soldering pen and USB port with the accompanying 140cm cable. It can get hot in 15 seconds and can cool down in 30 seconds, so you need little time for preparation and clearance.
The USB soldering pen stays hot only by maintaing pressure on the ON/OFF switch, so there is no need to worry whether you shut off the power or not.
