DOA Pinecil?

[Ralim]

I checked with multiple power supplies--when I plug in a 12V supply the little numbers on the right of the display ramp up to 12; when I plug in a 60W USB-C PD supply, they ramp up to 20. So I don't think the Pinecil thinks it's undervolted.

And I don't think the power connector is loose, because it works fine in the menus; it only happens when I go to solder.

I tried pulling out and reseating the tip just to confirm that it wasn't the problem--no change.

If the unit is tripping off as soon as you attempt to heat the tip this is most likely a poor power supply or a bad tip.
