So this is the full set I have the iron, the tips, and the storage case. Good old Aliexpress special since most of my deals and tools all come from China.
Never seen an iron run so quick it’s ran via USB-C PD 20v max. The heat up is quick as long as you have that 20v even 12v is quick heat up.
At first, when I tested what I believed to be a 20v USB-C PD when I hit the ok on boot, it just reset itself. I found hold down the OK button you get the menu. Changing it to 12V worked just as good, but my true 20V is still my go to.
Few repair jobs have been done with this as the quick change tips are great no need to wait till tips are cold to unscrew and chamge with these as long as you have something to pull and hold you can pop your next tip straight in and back to welding.
