Most disposables lock in one flavor intensity from the first puff to the last. The Adjust MySweet 40K adds a control: tap a button to move through four sweetness settings, shown on the screen as sugar cubes. Independent testing found that the control does more than sweeten. It also changes how full the hit feels. Here is how it works, how the three power levels fit in, what the flavors were like, and the one catch worth knowing before you buy.
A note on sources: the specifications come from the ivape.shop product listing. The hands-on observations, meaning the feel of the draw, flavor notes, battery life, and charge time, come from an independent review by Vaping360 published in March 2025, not from testing at ivape.shop. They reflect one reviewer's experience.
How the Sweetness Control Works
A button on the side of the device controls sweetness. Press it until the screen lights up, then keep pressing to cycle through the settings. Sugar cube graphics drop down the screen to show where you are, from zero cubes up to three, which makes four settings in all. The product page describes the low end as cleaner and more fruit-forward and the high end as a candy-style finish, and it suggests starting at a middle setting and adjusting after a few puffs.
The sweetness control does not change nicotine strength, which stays at 5% (50mg) on every setting. The available materials also do not explain how the device achieves the adjustment, so treat it as a feature to try rather than one you can reason out from the specs.
Quick specs: 20mL prefilled capacity · 850mAh battery, USB-C with pass-through charging · Triple mesh coil (per the independent review) · 4 sweetness levels · 3 power levels on a bottom slider (up to 40,000 puffs on the lowest) · Airflow tied to the power level · Digital screen with battery and liquid meters · 5% nicotine · $9.59
Sweetness Also Changes the Hit
This is the finding that makes the MySweet more interesting than a simple flavor tweak. The independent reviewer noticed that raising the sweetness level also seemed to raise the power output. At the lowest power level with no sugar cubes, the hit was the coolest and lightest of all the combinations. With three sugar cubes on that same power level, it felt fuller, even fuller than the next power level up with no cubes at all. The reviewer could not say why this happens and called it a net win.
The practical takeaway is that you have two dials for intensity instead of one. If a flavor feels thin at a given power level, try adding sweetness before moving the slider, and if it feels too heavy, take a cube off. Nicotine concentration is unchanged either way. What shifts is how full the draw feels.
Three Power Levels on the Bottom Slider
A slider on the bottom of the device powers it on and selects one of three power levels. According to the independent review, airflow is built into those same positions, so moving the slider changes both the power and how open the draw feels.
| Slider Position | Draw Style | Rated Puffs |
|---|---|---|
| Power Level I | Near mouth-to-lung, lowest airflow | Up to 40,000 |
| Power Level II | Looser mouth-to-lung, medium airflow | Up to 30,000 |
| Power Level III | Loosest mouth-to-lung, highest airflow | Up to 20,000 |
Our product page refers to a Normal Mode and a Burst Mode, while the independent review describes three slider positions, so check the slider on your unit. Notably, even the highest setting stays on the mouth-to-lung side, so this is not a device for a wide-open direct-to-lung pull. If you are unsure which style you prefer, our MTL vs DTL vaping guide explains the difference.
Build, Mouthpiece, and Screen
The MySweet uses a lightweight plastic C-frame body in a box-mod style, with embossed geometric patterns and a grip the reviewer found comfortable and familiar. The mouthpiece got particular praise. A subtle indentation sits under the center of the upper lip, and the reviewer called it one of the most comfortable they have used.
The screen shows battery and liquid levels as meters divided into quarters. They are easy to read at a glance, though the reviewer would have preferred numerical percentages, and finer details are harder to see in direct sunlight. The sweetness button is a square, transparent button shaped like an ice cube, a design carried over from the sibling MyCool that the reviewer felt does not quite fit the sweet theme. It is responsive, with a soft click.
How It Hits
The independent review describes a near mouth-to-lung draw on Power Level I that loosens through levels II and III, with quick, responsive coil activation and strong flavor. The one complaint was a slightly congested sound from the coil at the lowest power setting with little or no sweetness. The reviewer's conclusion was that these Adjust devices like to be pushed a little, and the coil performs best with more power, whether that comes from the slider or from added sweetness.
Flavors: What Independent Testing Found
The reviewer listed six flavors for the MySweet: watermelon roll ups, raspberry orange, lemon heads, blue razz b-pop, wintergreen, and triple berry. Four were tested, and they described the flavors overall as accurate, clean, vibrant, and punchy. In order of preference:
- Raspberry orange: tart, bright, and sweet, with a citrus bite on the exhale
- Watermelon roll ups: bright, tangy, and nostalgic, good without added sweetness and better with it
- Lemon heads: a close match for the well-known candy, with one of the widest ranges of change as sweetness goes up
- Blue razz b-pop: sweet berry and tart blue razz, good with added sweetness but not dependent on it
Wintergreen and triple berry were not covered in the review's flavor notes. Lineups change, so use the flavor dropdown on the product page to see what is currently available.
Battery Life and Charging
The 850mAh battery lasted about a day of moderate use in the independent test, with the caveat that the three power levels and the added power draw from sweetness make results vary. Charging is the weak spot: a full charge took about 100 minutes, which the reviewer called the main drawback across Adjust's adjustable lineup. USB-C and pass-through charging soften that, since you can keep using the device while it charges.
Since higher sweetness and higher power levels both seem to draw more power, expect shorter battery life if you run the device at the top of both. Recharging before it fully drains helps keep the draw consistent.
How It Compares to the Other Adjust 40K Devices
Adjust builds each of its 40K devices around one adjustable idea. The MySweet adjusts sweetness, the MyCool adjusts ice, the myRusher is built around a high-intensity Rush Mode, and the MyFlavor mixes two flavors in one device. We cover the others in our Adjust MyCool 40K review, our Adjust myRusher 40K review, and our Adjust MyFlavor 40K review. In the reviewer's own ranking of the three adjustable models tested, the MySweet placed above the MyCool, and it was called highly recommended.
Who Should Buy the Adjust MySweet 40K
It is worth a look if you
- Find fruit and candy flavors either too sweet or not sweet enough and want to tune them
- Like having a second dial for intensity alongside the power slider
- Want a high-capacity device at a low price
- Prefer a mouth-to-lung draw across every setting
Consider something else if you
- Need a fast recharge, since 100 minutes is a long wait
- Want numerical battery and liquid readouts instead of quarter-step meters
- Want a loose, direct-to-lung draw
Final Verdict
The Adjust MySweet 40K earns attention because its signature feature worked in independent testing. The sweetness changes were noticeable, the reviewer found them natural rather than artificial-tasting, and they also changed the fullness of the hit. The reviewer scored it 4.5 out of 5 and called it highly recommended, with the long charge time as the main complaint. That is a single source and a test from March 2025, and our listing describes the power modes differently, so treat the details as a guide and not a guarantee. At $9.59, it is a low-risk way to find out whether adjustable sweetness suits you.
Frequently Asked Questions
How does the sweetness control work on the Adjust MySweet 40K?
Press the side button to cycle through four sweetness settings, shown on the screen as zero to three sugar cubes. It does not change the nicotine strength, which stays at 5%. Independent testing found the change clearly noticeable in flavor and also found that higher sweetness seemed to make the hit fuller.
How many puffs does the Adjust MySweet 40K get?
It is rated for up to 40,000 puffs from a 20mL tank on the lowest power level. Independent testing lists 30,000 puffs on the middle level and 20,000 on the highest. These are maximums, and real totals depend on how you draw and which settings you use.
How long does the Adjust MySweet 40K take to charge, and how long does the battery last?
Independent testing measured a full charge at about 100 minutes over USB-C, which is the main complaint. The 850mAh battery lasted about a day of moderate use, and pass-through charging lets you keep using the device while it charges.
Does the Adjust MySweet 40K have adjustable airflow?
Yes, but it is built into the power slider and not a separate dial. Independent testing found airflow ranging from a near mouth-to-lung draw on the lowest power level to a looser mouth-to-lung draw on the highest, with no direct-to-lung setting.
