The 30 Watt MVP 3.0 is essentially a beefed-up version of the hugely popular MVP 2.0. Same huge 3800mAh battery capacity, same output charging option, durable build quality, etc etc. What's different, though, is that it can now fire sub-ohm clearomizers (sub tanks, atlantis, melos, RDAs, etc etc) as low as 0.4 ohms. It also has more output with a maximum wattage of 30 and maximum voltage of 9!
