If I were to select one beginner's setup, I'd probably go with the zelos 50 watt mod, it's easygoing, it has an internal battery, and at the wattages you'll be starting at, it should be good to go, fully charged, for a workday, etc. If you want to start MTL the zelos comes as a starter kit with the Nautilus 2, and it's a very nice setup that way, I have the aspire zelos 75 (that does TC, also, supposedly, I haven't been impressed with it so far) as my backup mod as it's portable, light, and easy going. You won't need an external charger, you'll be charging via USB, which in my mind is not a dreadful thing, considering this will be your first setup. I mean, if you find you want more vapor, less MTL type vaping, you can always go with a boxmod at that point.
So basically, you need the aspire zelos starter kit (50 or 75, I got the 75 mainly for better battery life) and you need some Nautilus BVC coils-- they come in 1.8, 1.6 and 0.7 boxes. If it were me and I could get coils quickly, I'd try both the Nautilus BVC coils and then order whichever ones you like best (I actually like the 1.6 coils best but they don't come with the N2) but I actually like all the coils for different reasons, and there's no harm in using either, you'll just be adjusting wattage and airflow, probably. The lower the resistance, the higher the wattage (usually) and the 1.8 is a much tighter draw than the 0.7, but that coil does get great flavor and I like it for coil life. As always, I am then using more battery life, and more juice, LOL, but it all seems to even out in the wash....
Lastly, you will need some juices. Most people starting out may choose a 50/50 mix of VG/PG, but it can be flexible. For example, I am sensitive to PG and have to use Max VG but I've found ways to make that work. Otherwise, PG is a thinner vape but tends to offer more throat hit, and is a flavor carrier, while VG produces more "clouds" with less throat hit, and sometimes less flavor-- most folks find their sweet spot easily.
Wattage range on the coil is printed in tiny letters on the coil. For starting, fill your tank with juice after you've installed a coil (one may come preinstalled) and let it sit for 10--15 minutes, taking long slow priming puffs to draw juice into the wick (don't hit the fire button!) then slowly start increasing your wattage while taking puffs until you reach a satisfying wattage, which MAY be below the "recommended" on your coil, which is fine, just don't go ABOVE recommended resistance.
I don't know how TPD regulations affect tasting juices, but you can purchase small amounts of flavors to see what kinds you like.
Don't worry, it's easy to get confused, but it's not super hard. You only need your starter kit, (if you run into issues, post questions here or look for a YouTube demo/review video) some coils, and some juice. Easy!
Best of luck,
