Vapor Beast says it's the latest version with the 4 amps & metal end caps. I love how you can see what the ohm of the atomizer or cartomizer is by pushing the power button once.
Yeah, that one is really nice. I'm not so sure about that 4 amp claim though. I've heard people say the limiter is 4 amps, but I think that 4ams actually refers to the rating of the switch. They were having problems with some of the switches on the Version 1 and probably upgraded it. I'm pretty sure the actual limiter is more like 3.2 amps., which is still very close to what the Provari2 will do and plenty good enough to run 1.5ohm DC cartos.
Unfortunately, the units with the hybrid connectors are still the older 1.0 electronics. They'll probably combine the two and call it the Version 2 in a few months. Then, they'll up the amps to 3.5, call it Version 2.5 and there won't be any significant performance difference between it and the Provari. That's my guess anyway. Of course, I certainly won't expect Provari owners to accept that, whether it actually happens or not. Provari's have special voltage and make special watts only Provaris can make.
