The istick 60 has no wattage adjustment in tc mode so the only way for more performance is increasing temp or using a diff. coil.
The Melo that comes with the istick kit isn't a bad tank but I'd put it closer to the budget side, it is not a cloud tank as such but is 100 times better than anything we had available 2 or 3 years ago for smoking cessation.
Another way to get more vapour is by using high VG liquids.
The camera supposedly adds 10 pounds. Probably makes clouds look bigger too. The devil is in the details, seemingly small changes add up to make a huge difference, for better or for worse. Cheers.
NO.. you are actually wrong here... (and don't want the OP to get wrong info)
I have THREE TC60W at my house (myself, my wife and my daughter all have one, and I've been using mine for 8-9 months)
YES, in TC mode for either NI or TI you CAN set the wattage. You only have to push the selection button and up or down.. just check any YouTube review and you'll see the reviewer do it.
It is the same system as the Pico (that my daughter has) or the TC100W (which I also have) and many other mods.
And I can push wicked clouds with my TC60W AND with my Melo2 that is very close to being on par with my drippers.
I have no clue where you're getting your info, and I mean no insult, but you are mistaking and possibly mixing yourself up about another mod.
I have several tanks, and the Melo 2 and 3 are fine tanks, better than many I've seen and tried, and it is still my daily main tank.
