Geek Vape WENAX K1 16W Pod System, featuring an integrated 600mAh battery, 16W output, and adjustable 3-tiered power output level. Constructed from durable zinc-alloy, the chassis of the Geek Vape WENAX K1 offers a lightweight and slim profile, perfect for daily carry in the bookbag, pocket, or purse. With 3 power modes, pocket fire protection, battery level indicator, button fire and auto-draw modes, the Wenax K1 puts some pretty impressive features out for a Pod device with only the one button! Top notch work here Geekvape, I love this even more than the previous Wenax Stylus! The pods apparently have a 300-400 puff lifespan and come in two versions – 0.8ohm and 1.2ohm – you get both in the kit.
