Off Stamp X Cube
Lost Mary makes the Off Stamp X Cube, a modular vape system. It breaks into two parts that work together instead of being a one-time-use device. The Reusable Smart Battery Device is a rechargeable 1100mAh power base with a TFT screen, power mode controls, and USB-C charging. The disposable Flavor Cube pod contains 18ml of 50mg salt nicotine e-liquid and a dual mesh coil. The pod attaches magnetically and clicks in securely. You change the pod when the e-liquid runs out, but you keep the same battery.
The Off Stamp X Cube is available in two pod types: Off Stamp Classic X-Cube for traditional fruit and mint profiles, and Off Stamp Sweet X-Cube for sour and candy profiles with a three-level adjustable sweetness feature. When combined with the Smart Battery Device, both types of pods can produce up to 25,000 puffs.

Performance: Power Modes, Airflow, and Vapor Quality
The three-level power system gives the X Cube a practical customization advantage over the SW-series, which offered no power adjustment at all.
|
Light Mode |
Smooth, restrained output. Best for tight MTL draws and battery conservation. |
|
Normal Mode |
Balanced everyday vaping. Good starting point for most users. |
|
Turbo Mode |
Dense, high-output vapor at 20+ watts. Best for maximum vapor production. |
Combined with the two-level airflow switch, users have six effective vaping configurations. Light Mode with tight airflow gives a dense, flavor-concentrated draw. Turbo Mode with loose airflow produces an airy, high-volume vapor output. The dual mesh coil performs consistently across all configurations, with even heat distribution from first puff to last.
Keep in mind that Turbo Mode will reduce the real-world puff count relative to the 25,000 rated capacity. Draw length and airflow setting also affect how long each pod lasts.

Off Stamp Classic Cubes Vapes Review
Each Classic Cube flavor delivers a clean, consistent profile with no sweetness adjustment. These cover the most popular profile types in the adult disposable vape category.
Sharp, tangy blue raspberry on the inhale with a clean menthol exhale. A well-balanced sweet-tart profile that hits the mark for fans of this flavor type.
Smooth citrus and cream with a sherbet finish. The citrus is bright without bitterness, and the creamy base makes this a comfortable all-day option.
Crisp, clean mint with mild citrus undertones. The menthol level is measured rather than sharp, making this accessible for mint fans who find most ice profiles too intense.
Juicy, natural-leaning peach throughout the inhale and exhale. The sweetness reads as fruit-forward rather than candy, with a clean finish. One of the strongest executions in the Classic Cube lineup.
A smooth tropical mix of dragon fruit, strawberries, and bananas. The dragon fruit adds exotic brightness that lifts a familiar combination into something more distinctive.
Tropical fruit with a light cooling finish. Pineapple and citrus are the dominant notes, and the icy exhale keeps the profile refreshing throughout.
Cherry, lime, and blue raspberry are layered in a nostalgic pop recreation. The balance between the three fruit notes is well-judged, and the throwback character is genuinely enjoyable.
Bangin Watermelon Classic Cube
Crisp, fresh watermelon that leans toward ripe fruit rather than candy. A cooling exhale reinforces the summer fruit character. A reliable crowd-pleaser.
Off Stamp Sweet Cubes Vape Review
The Sweet Cube collection is built around sour, candy, and gummy profiles. The adjustable sweetness button cycles through three intensity levels, which meaningfully shifts how each flavor reads. Level 1 is tart-forward, Level 2 is balanced, and Level 3 adds a pronounced candy sweetness on top of the base profile.
Sour Wildberry Gummy Sweet Cube
Mixed berry gummy with a sharp sour note at Level 1. By Level 3, the sweetness softens the tartness into a fuller, candy-shop character. A strong showcase for the sweetness control feature.
Watermelon gummy with a sour kick. Level 1 is bold and tart. Level 2 hits the best sweet-tart balance. Level 3 shifts to a sweeter candy watermelon finish.
Deep Concord grape candy. At Level 1, it reads as tart and fruit-forward. Level 3 delivers the full candy-store grape experience. The sweetness adjustment works particularly well with this flavor.
Sharp, zesty lemon candy. Level 1 is intensely sour and energizing. Level 3 smooths it out into a lemon drop profile. One of the Sweet Cube collection's most unique flavors.
Sour Berry Bubblegum Sweet Cube
Mixed berry tartness over a classic bubblegum base. Lower settings highlight the sour berry notes. Level 3 brings the bubblegum sweetness to the front. The two flavor parts work well together.
Strawberry Rolls Up Sweet Cube
Vivid, tart strawberry candy across all three levels. The sweetness control shifts the profile from tangy to fully candy-glazed. Works well as an all-day vape at Level 2.
Cool wintergreen mint with a candy sweetness underneath. Level 1 is clean and crisp. Level 3 brings the candy undertone forward, making this a notably different experience from a standard menthol vape.

Off Stamp X Cube FAQs
Is the Off Stamp X Cube compatible with the SW9000 or SW16000?
No. The X Cube uses a new pod system and is not compatible with SW9000 or SW16000 pods. SW-series users need to purchase the full X Cube Kit.
What is the difference between the Classic Cube and the Sweet Cube?
Both pods share the same 18ml capacity, dual mesh coil, and 25,000 puff capacity. The Classic Cube has eight traditional flavor profiles with no sweetness adjustment. The Sweet Cube has eight sour and candy profiles with a three-level sweetness button that changes the flavor intensity.
Can I use the pod without the Smart Battery?
Yes. Each pod has a built-in 100mAh battery for standalone use. Attaching the Smart Battery unlocks power modes, screen monitoring, and the full 25,000 puff capacity.
Who makes the Off Stamp X Cube?
The Off Stamp X Cube is made by Off Stamp and powered by Lost Mary, a globally recognized name in the vape category.
Final Verdict: Is the Off Stamp X Cube Worth It?
Yes. The Off Stamp X Cube is one of the most complete modular disposable vapes. The TFT display, three power modes, two-level airflow, and the Sweet Cube's adjustable sweetness place it well ahead of the SW-series it replaces. The Classic Cube collection covers the most popular flavor profiles for adult vapers with consistent, well-executed results from start to finish. The Sweet Cube collection goes further, giving users direct control over flavor intensity in a way that no standard disposable can match.
The two limitations worth noting upfront are the lack of a lower nicotine option and the absence of backward compatibility with the SW-series. For adult vapers who are new to Off Stamp or ready to move to an upgraded system, the X Cube is a strong recommendation. Find more at LostMaryDirect.com.
