What’s up man. Tbh I would be looking into pod systems if you aren’t that bothered about size and want it smaller.
I run a espion infinite and a cleito 120 (cloud chaser) set up when I’m at work (work in a vape shop) to demonstrate and explain the differences to people however when I’m not doing that or I am at home I run a pod system like the eleaf iwu or a tereos. lightweight as hell!
battery currently lasts me 8-9 hours of use off a 30 minute charge. Only downside with pod systems are if you fill a pod which is both your tank and coil and the coil burns you are kind of stuck loosing 2ml of liquid it’s really not that big of a deal but for some it can make all the difference
that would be my best advice but realistically stick your head in a vape shop. any that’s worth their Salt will have the time to talk through options with you and discover what’s out there and what works best for you!
