Which One’s Actually Better?
Let’s not bury the lead here: the Adjust Mycool 40K is the better all-around vape—by a long shot.
It delivers better flavor, more vapor, more control, and a smoother experience overall. If you’re into icy vapes, you’ll absolutely love the cooling control.

Even if you’re not, it still beats the Myflavor in battery, vapor production, and user feedback.
The Adjust Myflavor 40K sounds great on paper: custom flavor mixing? Yes, please! But it’s kind of like those weird cola machines that let you mix 200 flavors and none of them actually taste good.
Cool idea, but the execution isn’t quite there.
Full, Hands-On Comparison
Flavor Experience
- Adjust Myflavor 40K: You can blend two flavors per puff using a 3-level mixer. Sounds amazing, right? Sadly, the flavors come off muted and sometimes even mismatched. It’s like having all the toppings on a pizza, but none of them work together.
- Adjust Mycool 40K: The 5-level cooling system is actually useful. From a light breeze to full-on brain freeze, it gives each flavor a new personality. Combined with the triple mesh coil, the flavors are punchy, smooth, and far more satisfying.
Battery & Charging
- Myflavor 40K: Decent battery life for a day, but the charge time is annoyingly long. You’ll definitely feel it if you’re a heavy user—plug it in and go do something else for a while.
- Mycool 40K: That extra 50mAh goes further than you’d think. It charges much faster via Type-C and handles power draw better, especially in higher turbo modes. Easily outlasted the Myflavor in my testing.
Airflow & Draw
- Myflavor: You’re stuck with a fixed draw—a slightly restricted lung hit. Fine for casual puffs but definitely not customizable.
- Mycool: Adjustable airflow is a game changer. Whether you like a tight MTL hit or want it wide open for clouds, it’s got you covered.
Modes & Adjustability
- Myflavor: Two modes—Normal and Burst. Burst gives a little extra kick, but the lack of airflow control limits the effect. The flavor mixer is fun at first but underwhelming long-term.
- Mycool: 3 Turbo Modes that actually do something. Turbo 1 is your battery-saver. Turbo 3 is a fog machine. Each setting balances power and puff count so you can dial in your ideal vape session.
Display & UX
- Myflavor: The digital screen shows your mix levels, battery life, and puff count. It looks cool, but it doesn’t do much once the novelty wears off.
- Mycool: Animated display with a smoother user interface. Cooling level, turbo mode, puff count—it all feels more modern and less gimmicky.
Ergonomics & Size
- Myflavor: More compact and lightweight, fits easily in any pocket. The bite-friendly mouthpiece is a nice touch.
Which Should You Buy?
Go with Adjust Myflavor 40K if:
- You’re curious about flavor mixing tech.
- You want a smaller, easy-to-carry disposable.
- You’re okay with average flavor and limited airflow.
Choose Adjust Mycool 40K if:
- You want big flavor, big vapor, and control over it.
- Cooling customization is a priority.
- You’re in it for long sessions and battery life.
Wrapping Up…
If you’re still on the fence, here’s the honest truth: the Mycool 40K feels like the real flagship.
It’s smoother, more powerful, and built with the kind of user-focused features that actually matter.
The Myflavor 40K? It’s interesting. It’s different. But it feels like a first draft. If you’re a flavor-mixing geek, it might be worth a spin.
For everyone else, just grab the Mycool 40K and thank yourself later.
