Tesla Invader 4 is coming out soon. Made from aluminum, weighs only 149g and it’ll be compatible with (dual) 21700/20700/18650 batteries. The Invader Mods are a very succesful series of variable voltage devices. Affordable and insanely easy to use with a variety of protections, they hit powerful just like a high end mechanical mod. Definitely a no brainer for the high wattage crew.
It’s on pre-order here
