Tesla Steampunk nano. Very durable, all metal mod. It's heavy, but almost indestructible in my experience, I've leaked through mine, dropped it, etc. It's got an efficient power conversion board so IMO I find it an excellent 2 battery mod (using the right batteries, that would be key as if you are vaping higher wattage, it might not be ALL the mod, what type of battery you get will change the performance of what you have now, (although you still may want a dual mod for convenience).
To learn more about batteries go here:
Mooch's Recommended Batteries | E-Cigarette Forum or here:
Baditude's Blogs | E-Cigarette Forum Both offer a ton of information.
So the right batteries for your wattage range should help. I suppose I should mention the Tesla's battery door, some models were a bit wonky on the door but there are various fixes if you love the mod (you may equally hate it the style isn't for everyone).
I'd also recommend the eleaf Invoke, it also does TC (although perhaps a bit inaccurately, but since you aren't looking for TC, it shouldn't impact you much). Many mods offer TC and you certainly can just not use it, as almost all mods other than a few of the two battery mods seem to be offering it, but it's always nice to have that option down the line. It's tiny, lighter than some of my single battery mods and etc. It may well be worth a look, it's light without sacrificing design quality and durable, for sure (I've dropped mine few times but all was well).
Good luck and I am sure you'll get more suggestions, but hope any of the above is helpful.
