Mortimer@mcrosson You're right, the 510 connectors diameter is Ø22mm. You'll have to file it down to 19mm to make it look even. I've clamped the connector in a cordless screwdriver and hold a file at the rotating object. The material is thin (1 mm?) so it's a quick work.
Hi Dennis, it's for 18350 sized batteries. Please use IMR batteries (e.g. AW IMR 800mAh; Blue Tensai 700mAh) as the DNA chip needs 12A @ 30W.
Hi, it's just the metal body part, no atomizer, no electronics. You'll need a DNA 30 chip, a 510 connector and two cylinder magnets Ø5 x 5mm
