Nexa Ultra II 50K Vape — Juicy Lock, Crystal Tank, 50,000 Puffs

What Makes the Nexa Ultra II 50K Special

The Nexa Ultra II 50K is the second generation of NEXA's flagship disposable vape, backed by VOOPOO. With up to 50,000 puffs and a massive 20mL crystal tank, this device goes the distance. The transparent tank lets you see exactly how much juice you have left — no guessing, no surprises.

What sets it apart? Juicy Lock anti-leak technology. The two-part design keeps e-liquid sealed until your first draw. Once you squeeze the device together, the seal activates and stays locked. This is one of the most leak-proof disposable vapes in the 50K tier.

Normal Mode vs Boost Mode

The Nexa Ultra II 50K gives you two ways to vape:

• Normal Mode — up to 50,000 puffs. Smooth, efficient output for all-day use. The device manages power automatically for consistent flavor and maximum longevity.
• Boost Mode — up to 30,000 puffs. Warmer vapor, faster saturation, and more intense clouds. One switch and you feel the difference.

Normal Mode is your daily driver. Boost Mode is for when you want that extra punch. Switch anytime — the dual mesh coils handle both modes without missing a beat.

Dual Mesh Coils for Rich Flavor

The Nexa Ultra II 50K runs on dual 1.0-ohm mesh coils. Two heating elements mean the e-liquid heats more evenly across a larger surface area.

The result? Richer, more consistent flavor and smoother vapor from the first puff to the last. No burnt hits. No flavor drop-off halfway through the tank. The mesh design keeps every draw tasting fresh in both Normal and Boost Mode.

15 Flavors to Choose From

The Nexa Ultra II 50K comes in 15 flavors covering fruity, icy, candy, and dessert profiles. Here are some standouts:

• Blue Razz Ice — sweet-tart blue raspberry with a frosty menthol finish
• Strawberry Mango — ripe strawberry layered with tropical mango sweetness
• Georgia Peach Ice — juicy peach with a smooth, icy exhale
• Fcuking Fab — a bold, candy-forward blend with a playful edge
• Sour Apple Ice — crisp green apple with a sour punch and icy kick
• Miami Mint — cool, refreshing mint with a clean finish
• Black Cherry — deep, rich cherry flavor with a sweet undertone
• Lemon Frozen — bright lemon citrus with a frozen menthol blast

The full lineup also includes B Pop, Blueberry Watermelon, Strawberry, Strawberry Banana, Strawberry Ice, Watermelon Ice, and White Gummy. Browse more high-capacity options in our disposable vapes collection.

Crystal Tank and OLED Display

The Nexa Ultra II 50K features a crystal clear transparent tank so you can see your e-liquid level at a glance. No more guessing when you're running low.

Paired with a 3D curved OLED screen, the display shows your battery level, puff count, and current mode in real time. You can even switch between Light and Dark display modes to match your style. It's a small touch that makes the vaping experience feel more personal.

Adjustable Airflow You Control

The Nexa Ultra II 50K features a bottom-adjustable airflow dial. Twist it to go from a tight MTL (mouth-to-lung) draw all the way to a loose DTL (direct-to-lung) draw.

Prefer a cigarette-like pull? Tighten it up. Want bigger clouds? Open it wide. Most 50K disposables give you zero airflow options. The Nexa Ultra II 50K puts you in control of every hit.

Battery and Charging

The Nexa Ultra II 50K runs on a 900mAh rechargeable battery with USB-C charging. A full charge takes about 40-45 minutes. The device also supports pass-through charging — you can vape while it charges.

In Normal Mode, a full charge lasts for hundreds of puffs before you need to plug in. Boost Mode drains the battery faster, so expect to charge more often if you run it hard. The 3D curved OLED screen shows your exact battery level so you always know where you stand.

How Long Does the Nexa Ultra II 50K Last?

With 20mL of e-liquid and up to 50,000 puffs, here's what to expect:

• Light vaper (casual, social) — up to 5-6 weeks in Normal Mode
• Average vaper (moderate daily use) — about 3-4 weeks in Normal Mode
• Heavy vaper (all-day use) — 1-2 weeks in Normal Mode, less in Boost Mode

The 20mL capacity matches the largest tanks in the 50K tier. And with Juicy Lock technology, none of that juice leaks out in your pocket or bag.

Nexa Ultra II 50K vs VIHO TRX 50K

The Nexa Ultra II 50K wins on e-liquid capacity and leak-proof tech. The VIHO TRX 50K takes the lead with a larger battery and quad mesh coil. Both offer adjustable airflow and OLED displays. Check out more devices in the 50,000-puff tier.
