I have one coming from a coop. no logo as we met the MOQ. Hopefully here soon and I'll test the voltage drop and give an update.
I'm also waiting to see somebody check the voltage drop and build quality of this. Lets just hope they didn't screw up on the contact materials (please be copper or brass). Also from the pictures iv'e seen theirs a spiderman logo on the bottom of the switch. the badassery of that almost outweighs the huge ugly Smok logo engraved on the side... almost.
I am skeptical of magnetic switches.
You tested it properly by testing it under load. The resistance of everything but the atty (including the internals of the battery) and the atty form a voltage divider circuit. The voltage you read is a function of the relative resistance of the atty and everything else. Higher voltage means less internal resistance of everything else.
Anyone else jhace problem with 18350 button top battery?
