Tesla has just released a new regulated version of the Tesla Two Sub Box it's the Tesla Nano 100W.
I've got the Tesla Two which I love. It's unregulated so depending on your coil build it can do even more than 100W, i think they just plucked a figure out of thin air there because it can fire down to 0.1 ohms before the user protection kicks in so if you do the math thats way more than 100W. It's got a total of 4000mAh and I usually build between 0.4 - 0.6 ohm on mine so I get about 14 - 18 hours of consistent vape time before I need to recharge. The thing I like about it the most is that it's small and very durable.
The Nano 100W looks like it's going to fill my need for a high powered regulated vape in a small form factor. From what I've seen in the
reviews it is only a few mm larger than the Tesla Two Sub Box and that is a very small mod. The Nano is 4500mAh with a 2A charge port which makes it twice as fast to charge than the Sub Box. I just need to see a few more reviews on it before I pull the trigger. Apparently it doesn't do more than 40W in TC mode, but I would only use it in VW mode so there's that to consider if you're a TC user.
EDIT: I just saw they have a 60W nano as well.
