How the Adjustable Flavor Works
A side button steps through four intensity levels. On the MySweet 40K they run from a light “Sweet Whisper” to a heavy “Sweet Hunger.” MySour works the same way for tartness. The screen animates sugar cubes or lemons so you can see the level at a glance. It is a simple idea: same flavor, different intensity, without buying a second device.
Power Modes and Battery
The MySweet 40K has an 850 mAh USB-C battery, a triple mesh coil and three power levels. Turbo I is the efficient setting and is where the 40,000-puff rating comes from; Turbo II is rated around 30,000 puffs and Turbo III around 20,000, with stronger hits as you go up. The airflow and power switch let you choose a smoother or fuller draw.

MySweet and MySour vs MyFlavor and MyCool
Adjust built a family of 40K devices around one idea, letting you tune the taste:
- MyFlavor: blends two flavors at three ratios. See our MyFlavor 40K review.
- MyCool: adjusts the cooling level. Shop the MyCool 40K.
- MySweet and MySour: adjust sweetness or sourness.
You can browse every model on the Adjust brand page, and the three-device Adjust bundle is $25.99.
Who Should Try MySweet and MySour?
They suit vapers who find most candy flavors either too sweet or not sweet enough, and anyone who likes sour candy but wants to control the pucker. If you prefer a straight, simple flavor at one fixed intensity, a standard disposable is easier. Value hunters will like the price: at $9.99 the MySweet 40K works out to about $0.25 per 1,000 puffs. Compare value across the store in our cost per 1,000 puffs ranking.
