********************************************************************************************************************
The two sections below cover my normal testing procedure and preface.
I feel this is important information to include so you know what I do to ensure I test everyone the same way.
It also provides you info on MY particular juice because it is more than likely different than yours so it can/will have different results.
********************************************************************************************************************
Airflow wide open for both coil tests.
Before testing each coil I ensured proper saturation as well as break the coils in by starting at lower wattages and temps.
I vape at these lower wattages, slowly increasing and I vape though half to a full tank fill depending on what the coil needs.
Once the coils are properly broke in I start my tests.
For each wattage setting I took 10 casual pulls taking them as I felt the need.
Followed by 10 chain vape pulls to check for heat and flavor changes.
I Wait 5 minutes between each setting (allowing the coil to cool) to ensure I get the best the coils can produce.
After documenting all notes through this process, I proceed to vape through 240ml of juice for each coil to check coil life.
********************************************************************************************************************
This may not seem news worthy to some but since high flavor percentages and really sweet juices kill coils, I check for it.
Mostly because I use 25% flavor of super sweet DIY juice and go through about 45ml per day.
My juice is a well-known coil killer.
Generally, I get only a few days out of coils so I'm always in search of the few that can last though my particular juice.
Clouds are clouds, I could care less.
Flavor on the other hand is where the importance to me is so that'll be my main objective.
********************************************************************************************************************
Airflow wide open:
(Uwell recommends air flow to be wide open if using recommended wattage, if you want to close the air flow down they suggest also reducing the wattage)
Including priming the coil I was able to fit 6.5ml of juice in.
The 0.15Ω is rated for 95 - 120W
Starting with the "unrestrictive type pin" that is recommended at 100 - 120W
NOTE; "unrestrictive" DEFINITELY means LOTS of air, LOTS! It is like breathing through a piece of 3" PVC tubing.
80 - Massive clouds, very little flavor
85 - Same massive clouds, almost a touch of flavor
90 - No noticeable change from 85W
95 - Flavor is just now starting to come in
100 - Small amount of juice guzzling flavor, still massive clouds
105 - Slight increase in flavor, juice temp remaining cool
110 - Good flavor and huge clouds but doesn't match the excessive airflow
115 - Just doesn't seem to be improving on flavor amount
120 - Still not much improvement
125 - Now we start getting a little flavor
130 - The most amount of flavor this thing has produced yet
Kept it at 130W and vaped 240ml.
With the "spiral type pin" that is recommended at 95 - 105W
NOTE; Changing to this pin did help restrict the air flow to an easier to manage volume.
80 - No flavor here, just clouds
85 - More clouds, little flavor
90 - No change
95 - ""
100 - ""
105 - ""
110 - ""
115 - Still producing massive clouds, just weak on flavor
120 - The flavor point here is acceptable but not what I expected
125 - More flavor but now wondering what my juice is going to do to the coil
130 - THIS is where the flavor should have been 5 settings ago, NICE
Kept it at 130W and vaped 240ml.
With the "wave type pin" that is recommended at 100 - 120W
NOTE; Changing to this pin seems to be about half way between the "unrestrictive" and "spiral type pin" as far as air flow goes.
80 - Fair clouds, lacking flavor
85 - Lot more clouds, very little flavor change
90 - Plenty of clouds, flavor starting to come in
95 - No noteworthy change
100 - Huge clouds, flavor slightly improving
105 - Clouds are more thick than before, flavor same as 100
110 - Slight increase in flavor
115 - A little more flavor but whistle is getting more annoying
120 - This juice guzzling tank is getting pretty close to where I want it for flavor
125 - This seems pretty nice but I can't see my screen through the fog
130 - Same as with the "spiral" pin, this is the setting that works best for me
Kept it at 130W and vaped 240ml.
One unfortunate observation is with this pin there is now an annoying whistle.
* No leaks, seeping, or issue of any kind.
Very well build solid tank that seems like it will cover the needs for any vaper that like airy tanks that produce a LOT of clouds and some great flavor.
While chain vaping tank does get pretty warm.
Mod gets a slight bit of heat transfer but none to drip tip.
