If going regulated mod, would recommend something that puts out at least 15 watts and 6 volts if headed in the rba direction. Many to choose from,
SvoëMesto and
Provari would be my top 2 recommendations. Both excellent devices and will give one years of quality vape. The Innokin Svd, Telsa, and some others would be good choices too.
If wanting to eventually get into mechs and sub ohm builds would highly recommend the
Hcigar Nemesis Clone mated with the
Evolv Kick 2 . The Kick 2 would turn a mechanical mod into a regulated VW mod that accepts builds from .5-3 ohms and puts out up to 15 watts, giving you all the protection of a regulated mod. A great device and combo if that's the direction one is going.
My first mod was the Provari, love it and still use it daily. The P got me into rba's and DIY juice and vaping at 15 watts. I then bought the Nemi clone and the Kick 2, and is a great device, I also added the magnetic switch upgrade. Vapes great with standard and sub ohm builds. The kick 2 fits perfectly in the nemesis in all battery configurations. Was the reason I chose the Nemi, wanted to kick it in the 18650 mode.
Whether you choose regulated or mechanical, you'll always want to go with quality IMR batteries. If choosing Mechanical, recommend batteries with a 30 amp limit, that way if you do go sub ohm you'll have the safest configuration when you are ready and have enough knowledge to do it.
There is a lot of great choices out there, many more than I have mentioned for sure. If you like box mods then the Reo would be a great choice, but that's not the direction I chose.
Good luck, be safe,
Vape long and Prosper.
