New Totse

They fucking blow. They don't even work on every pen, including my Ooze pen that's specifically made for carts.

Can u read the ohms with a meter? Could be defunk
Id say out of about 500 10 are gunna come DOA

It'll work on some pends but not all pens. The 510 pin is too shallow to make an adequate connections. The issue is in the cart itself, not the stuff within the cart, which isn't that good.

Is the pin hollow? Or pull down at all

It's hollow, I tried pulling it down, doesn't work. I wouldn't have made the thread if there was anything at all that worked.

its prolly like 2ohms use some soder or a foil or paper cap my duce, old as cart from back when vapes didnt need protruding pins, every thing is spring loaded 510 these days, i believe theirs a adapter

I'm not going to modify the cart. The point of the thread is to inform people to stay away from Champion Carts until they fix this glaring design flaw.
