30W – Not much yet in terms of clouds, but already surprisingly good flavor.
40W – I think this is what the battery should fire at that comes with the kit. Amazing flavor at 40W and lovely clouds of cool vapor.
50W –Amazing flavor! Wow, this sub ohm tank is up there in terms of our favorites, like the Crown and Freemax Starre. Vapor production is also very impressive without being too warm.
60W – A much warmer
vape now, but the flavor is just outstanding and with even more vapor!
70W – Massive clouds, but the vapor is now quite hot, not unbearably so, but definitely on the warm side. The tank itself is doing a really good job of keeping cool though.
80W – Too hot now for my liking but the flavor is gorgeous.
I have the ELeaf IJust2 and love it. I am running it at 60W. Nice taste,and cumulus nimbus clouds. I have been using it for a month now with the original coil.
If you are getting dry hits it means there is a problem with E-Liquid getting to the cotton wick. "chain vaping can cause this" or its a bad coil. once its burned it tastes gross no matter how much fluid is on it. So I would take the tank apart for inspection, a good cleaning as well. Q-Tip the mess under the coil, and then replace the coil. Let the coil soak for 5 to 10 minutes before use. You can not rush perfection, and coils are to expensive to play. I am careful when installing a new coil to never touch the e liquid to wick ports on the coil, it may or may not be a mute point by your skin does have oils on it and this can effect the wick.
Good Luck, Hope things turn around for you.
