There is no unifying sweet spot. The sweet spot for him and some others is 25w, depending on the juice they are vaping. The sweet spot for me and the juice that I use is 20w, as the juice flavour disappears if it's any hotter. Of course I can change the jucie and that may require more of less watts.
someone (I think UK tweet) posted the other day that he vaped his at 17.5. It all depends on the persons requirements.
Like wise with the battery, depending on the make and model of the battery and more importantly how much you vape and how long your day is.. will of course affect if the battery will last you all day.. I know for a single Efest 2100mah 18650 which is 6.5 cm long will easly last me just about 2 whole working day, if I'm sub ohming, as I have other mods that I will use once I get home.
Jumping between the using a 2 ohm coil and 0.5 ohm is a massive step.. It's pretty much the two polars of common vaping at the moment, heck you might not like it.. My typical coil setup is around 1.5 or 1.2 depending on the tank I'm using, you may want to try it out in a local vape shop first before buying into it.
Sub ohming before the kanger mini and nano came out and made it more popular and the "in thing" was considered as a dangerous activity and not the "normal". Even when the full size subtank and Atlatis came out, sub ohming was pretty rare. With cheap (and possibly poor) regulated mods firing as low as 0.5 now or lower, it's removed some of the danger, but there is STILL a danger, should "sub ohming" be considered as the "norm"?
It's like someone buying a super car after a few months of passing their test and getting bored driving around in their mum's fistea, there's a whole mid range market that really should be experience. Ohms law learnt about (correctly!) and battery management! I'm not directly this at anyone, but yes; IMHO the subtanks is the best commonly available tank bang for buck on the market today, but recommending it to everyone; without knowing their level of experience is irresponsible. It will only take one noobie to hurt themselves.
I personally think there's three so called levels of vaping;
Noobie: ego/EVOD/clearo tanks and ego batteries, which everyone gets suckered into.
Inter: vv/vw devices (isticks 30w/50w) and tanks with adjustable airflow (aspire nautilus)
Adv: sub-ohming, RDA/RTA, mech mods..
I would have loved to have skipped the noobie level all together, as I consider it a waste of money; thou at the time I didn't even know if I would like vaping rather than smoking, and the cash investment in the 'next level' of kit pretty much doubles.. But I would recommend to anyone starting or using ego batteries (non adjustable batteries) that want something better to get an eleaf istick 30w/50w with an Aspire Nautilus (or mini), end of... Full stop...
It's pretty safe to say that most vapers don't need to go into the "advance" levels of vaping, heck I don't drip or sub ohm everyday (not considering myself as the benchmark), but I'm pretty sure when someone wants to getting into rebuilding, running mech mods and sub ohming, they should be pretty clued up enough to know about safety, know what they want, why they want it, the limits and how to use that device.
Sorry I'll take my mothering apron off now.
lol
Vape on... But vape safe
If you want something that has removable batteries so you can just put a fresh one in when it runs out, my vote goes to the Sigelei 30W mini, I'm very happy with mine but that does mean you'll have to buy some batteries and a charger. It does actually have a USB charging port but that doesn't take advantage of the flexibility of having removable batteries imo. 30W is easily enough to power the Subtank, I find 25W to be the best for it.
