Switched, agreed. 20% is about right. But it will also depend on the flavor, as some are thinner than others. My Loranns Eng Toffee juices want about 10% water. Anything more is too thin. So one has to experiment a bit.
I also find that with stronger batts, like the 14500, 15% water is about right on average, sometimes less. Higher wattage likes a bit thicker juices, I have found.
Interesting observation Kurt and I must admit I never really through it in the equation (flavours). My rationale is that the majority of flavours are suspended in PG to start with, so. If I make my VG the same consistency as PG, I'm all set.
Where you are getting me is on the 15% water when using a 14500 batt. You must be a dripper, is this correct? If the latter is indeed correct then yes you have an extremely valid point. I use carts and drip little. I use the HP simple cart mod on 510 attys.
I have experimented with various ratios PG/VG from 65/35 to 80/20. My bases are 80/20 for all my DIY, with the exception of 75/25 on odd occasions. I prefer the flavour of a lesser concentration of VG. This is carried out with all my
devices and my 14500 box mods, of which one is a reg 5V on wich I use a 801 atty and a 75/25 liquid.
IMHO high VG leads to premature atty failure because of the "wetiness" of the liquid, it not as cooling and thus runs the atty too hot, whilst still lacking in flavour. The chief advantage is that high VG liquids when dripped do not leak as much, but there is a caveat there.
Although high VG liquids do not leak as much, they are also not as flavourful, and subsequently we drip more. Drip more = more leakage. IMHO it also has another draw back, it operates the atty in a semi flodded state, which causes greater resistance and hence premature failures.
On the other hand, a lesser VG concentration produces more flavour per drop than one with a higher concentration of VG. In doing so you are not topping off as often, maintaining the atty just wet, no leakage and because of no increase in resistance caused by a semi flooded condition, a longer atty life.
I have come up with a line lately wrt leakage"
You are either dripping too much or not vaping enough.
I have very little if any leakage these days, even with my low ratios. Because IMO PG is not as greasy as VG, it has greater "wetiness" and helps maintain the atty cooler.
I was getting 4-5 good hits compared to 8-10 good hits with a lower % VG. vapour production has not signifcantly decreased (negligible IMO) because once again IMHO, the atty is working at peak performance.
I am really looking forward to play with my theories further with the coming of my Chameleon, my first raelly HV device.
