Hey I've been vaping for a few months now and I just bought the aspire cleito as an upgraded tank to my original kangertech suntan nano. The coils minimum wattage says 40 watts but I find it way too hot for my liking. I used to be around 17 to 25 with my old tank. How low can I go with the coil if I can at all. Oh and I'm using istick tc 40 watt.
The overall shape and size, the dimensions of the factory coil head body, the size of the juice holes and even the amount of wicking material in an
entire tank system are
designed to give optimal performance... within a range of wattage.
If you go too low (too high will burn, obviously) you will have less vapor (no big deal) and possibly excess un-vaporized juice on the wick creating mild flooding and gurgling.
But it won't hurt anything. Not the tank, not the coil, not the mod.
If you can get a more pleasant vape at a lower wattage... go for it.
