Introducing the MySour 40k disposable vape, another flavor adjustable disposable from Adjust, featuring 4x sour levels to make you pucker. That's the latest in Adjust's line of flavor-adjustable disposable vapes. The MySweet, MyCool, and MySour are effectively the same devices with the same specs, just with different flavor adjustments and screen icons. The MyFlavor, which I recently reviewed, is totally different than the other three.

• Puff Count: Up to 40,000 puffs (varies by power mode)

• E-Liquid Capacity: 20mL pre-filled

• Nicotine Strength: 5% (50mg/mL)

• Battery: 850mAh rechargeable

• Charging Port: USB Type-C

• Coil Type: Mesh coil for smooth vapor and rich flavor

• Display: LED screen showing battery, e-liquid level, puff count, and mode

• Firing: Draw-activated

• Airflow: Adjustable

Right out of the box, the Adjust MySour 40K is ready to impress. With an incredible capacity of up to 40,000 puffs, this disposable vape outlasts the competition. Whether you’re a casual user or a daily vaper, you won’t be needing a replacement anytime soon. It's the perfect device for travel, work, or anyone who wants to avoid the hassle of constantly restocking.

This isn’t your average disposable vape. The Adjust MySour 40K is equipped with dual vaping modes—Eco Mode for smooth, consistent puffs with optimized battery use, and Boost Mode for more intense vapor, flavor, and throat hit. Want a laid-back session during the day and a more powerful hit in the evening? Just tap the mode switch and adjust to your vibe. It’s all about giving you choice, freedom, and a tailored vape every time.

• 4-level adjustable sourness

• Adjustable power settings and airflow

• Targeted at fans of tangy, punchy flavor profiles

And speaking of control—this vape also features a built-in LED display screen that shows both battery life and e-liquid level. No more surprises when your vape runs dry or powers down. With the MySour 40K, you’re always one step ahead. The digital readout takes the guesswork out of vaping and adds a modern touch to an already sleek device.

One of the standout features  of the Adjust MySour 40k is its USB-C rechargeable battery. Unlike traditional disposables that die before you finish the juice, this one charges fast and keeps going until every last drop of e-liquid is used. That means fewer disposables wasted, more value for your money, and a more eco-conscious way to vape.

Inside the device is 18mL of high-quality salt nicotine e-liquid, perfectly balanced with a 5% (50mg) nicotine strength. Whether you’re looking for smooth satisfaction or strong throat hits, the MySour 40K has you covered. And thanks to its dual mesh coil technology, each puff is smooth, flavorful, and consistent. Mesh coils are known for faster, even heating, giving you better flavor and longer-lasting performance.

The Adjust MySour 40K is available in a wide range of carefully crafted flavors designed to satisfy every palate. Some of the standout flavors include:

• Sour Blue Razz Ice: Tart blue raspberry with a chilling ice finish for an exciting vape.
• Sour Grappie: A bold sour grape flavor with a tangy and refreshing twist.
• Sour Island: Tropical fruit flavors combined with sourness for a vibrant and zesty vape.
• Sour Peach Raspberry: Juicy peach and tart raspberry with a sour kick for a flavorful hit.
• Sour Pinkberry: Sweet and tangy pink berries with a sour burst.

Each puff delivers full-bodied flavor that doesn’t fade or burn out halfway through the device. That’s thanks to the combination of premium ingredients and advanced coil engineering—something you’ll notice immediately and appreciate long-term.

Despite all this power, the MySour 40K remains compact, lightweight, and easy to carry. Its ergonomic shape feels great in your hand, and the minimal, futuristic design fits right into your everyday life. Whether you’re heading to work, out with friends, or just relaxing at home, this device fits your lifestyle.

If you’ve been looking for a disposable vape that doesn’t compromise—on flavor, puff count, or control—this is it. The Adjust MySour 40K delivers serious performance with no mess, no refills, and no fuss. Just powerful flavor, massive clouds, and the kind of reliability every vaper wants.
