Vape Design
The MyCool 40K has a small, comfortable design with a C-frame. The outside has a textured pattern that feels good and secure in your hand.
It looks playful yet mature. The main body is off-white with a light grey fern pattern. The screen panel has a metallic color that hints at the flavor.
The mouthpiece is designed to be comfortable to bite on, similar to the Geek Bar style. I usually get juice in my mouth with bite-friendly mouthpieces but not with the Adjust MyCool.
Now, let’s talk about the cool button! It is just for adjusting ice levels, but it’s one of the coolest details I have seen on a disposable.
The button is transparent with an ice-cube texture that increases or decreases ice levels. When you press it, the screen lights up to show your ice levels.
Press it again, and an ice cube graphic slides down the screen, showing another level added.
When you take a hit, the ice cubes slide down the screen one by one, maxing out at four ice cubes. I do not usually get excited by such things, but this button and screen are just too cool.
Note – The button is where a fire button would usually be but it is only for adjusting ice. The MyCool Adjust 40K Vape has an automatic draw.
Using Guide

Setting up the MyCool 40K is easy and fun. After you take it out of the package, you can start vaping right away by turning it on.
On the bottom of the device, there is a nice slider switch that turns it on/off and adjusts the power levels and airflow.
Each power level clicks into place and has its own airflow. So, if you want more airflow, you will get more power and if you want less power and airflow, you can adjust that too.
To change the puff modes, just toggle through Turbo I, Turbo II, and Turbo III, which are shown on the screen above the ice cubes.
The power levels use liquid at different rates. Here is how much liquid each mode uses:
- Turbo I (MTL; 1x airflow hole) – 40K puffs
- Turbo II (loose MTL; 2x airflow holes): 30K puffs
- Turbo III (looser MTL; 3x airflow holes): 20K puffs
Changing the ice levels does not use more liquid so you can have strong ice with low power/airflow without using a lot of juice. The e-liquid and battery levels are shown by small icons at the bottom of the screen.
Each icon is shaped like a square divided into four parts. It is a subtle detail, and I missed it when my battery first ran out—I saw the lightning bolt but did not realize the meter was at zero.
About Hit
The MyCool 40K gives a smooth, quiet, and tasty hit that starts quickly with its triple mesh coil. This coil gives clean and strong flavor.
You will feel a throat hit at each level, and it gets stronger with higher power levels. Adding ice makes the throat hit even more intense if you like that.
I have tried many devices with different flavors, power, and nicotine levels but the MyCool has the most noticeable differences (except for the ZLand).
The Adjust MyCool does not quite give a restricted lung hit like the NEXA ULTRA, but I am still happy with it.
I think the best experience is with Turbo III mode and at least 1x ice, but it depends on the flavor. Usually, I do not like the cooling sensation in disposable vapes, but the Adjust MyCool is different. The ice really enhances the whole experience, making it more lively and exciting.

Adjust MyCool 40K Flavors
The flavors on the MyCool 40K are bright, complex, and just like the description. Many of the flavors are sweet and tart, which go well with ice. Here are my five favorites:
Dragon Strawnana – A tropical taste of dragon fruit mixed with sweet strawberries and a hint of bananas on the exhale. Best with 2x ice and Turbo III.
Sour Lush Gummi – A sour version of pineapple gummy bears. Best with no ice and Turbo III. Ice can overpower the flavor which already has some ice. Turbo III brings out more sweetness.
Cherry Strazz – Sour cherry and sweet strawberry mixed with tart raspberry. The different tastes play well together. Best with 1x ice on Turbo III.
Scary Berry – A mix of berries with a lot of strawberry. It is a complex, sweet/tart flavor that is really good! Best with no ice and Turbo I. There is already enough ice in the flavor.
Tiger’s Blood – Maybe strawberry and cranberry? Not sure. It is a mystery mix with a dark red fruit flavor and a jolt of sour. Tiger’s Blood is better with each ice cube and power mode. Best with 4x ice and Turbo III.
About How Long Last
After my first battery ran out, the liquid level meter still showed four bars (a full square). Even though I get about two charges per bar by the last bar the liquid started tasting strange with some flavors. So, I think the liquid meter isn’t very accurate.
With an 850 mAh battery, I can vape all day without worrying about recharging. But I did suggest charging it at night because one downside of the MyCool is that it takes a long time to charge.
It takes over an hour to go from empty to full. Luckily, the Adjust 40K has pass-thru charging so you can charge it during the day if needed.
Last Words
If you want a versatile and customizable vaping experience the MyCool 40K is perfect. It has the industry’s first ice adjustability, and it works great. The flavor is impressive, and the different power modes make it even more flexible.
The cons are the long charge time and the liquid meter not being very accurate. These issues can be annoying, but they’re common with many disposables.
Out of all the new disposables with ice adjustability that I have tried, none can compare to the Adjust MyCool 40K.
