Yeah, the Hadron had an add on squonk backpack which was a pumper.
Pulse V2 keeps it simple, and even though made from the finest Czechoslovacian ivory (plastic) is pretty life proof especially with the G10 panels.
There's the Lost Vape Centaurus BF too, for another option.
But with a Molicel P42A 21700
@Alex Mohler I'd say that you were okay down to about 0.2 ohms and no less.
Couple that with a good single coil RDA with a reduced chamber volume and you should definitely get way above it.
So you've even got clones of BTD, Hussar II and Citadel. All the enjoyment of the originals, but for a fraction of the cost.
