MVPs only go up to 11watts my 1.6 and 1.8 ohm nautilus works good 4volts; but at 7 or 8 watts its perfect. so for any mod or tanks a person has different settings but you have to find your setting. all e-liquids or e-juices are different. oh a MVP has no comparison to a IPV2 at all I own both. for 1. an iPV has n variable voltage 2. iPV's wattage is a different,
