Thanks again for all the suggestions. As I said, I'll give him several choices but I think I'm going to recommend the Innokin iTaste VV V3. This seems to be a quality, inexpensive device that would be good for a new vaper such as my friend to experiment with and see if he likes
vaping. I'm going to recommend he buy just one and keep it plugged into his computer to keep it charged when he's not using it or just keep a check on the battery life via the LED lights and charge it periodically when needed.
The full-sized Nautilus will fit on this, correct? I think it should be as simple for him as possible so I think he'll prefer the greater juice capacity of the full-size, rather than having to fill a mini every few vapes.
Speaking of simplicity, I'm not familiar with a VW device so I'm not sure how that works. On my Provari I vape the Nautilus BVC 1.8 coils at 3.7 volts for most juices. This is the setting I'll recommend for my friend to start off with. How would he input a similar setting on the Innokin iTaste? Thanks!
