Product Highlights at a Glance
- Highly Overlapping Product Lines
LOST MARY X-LINK closely matches ELFBAR’s JOINOne in product form, device structure, and feature set, including the screen-equipped Dynamic Device and the Standalone Use pods that can be used independently.
- Two New Adjustable Pods
Building on JOINOne’s original cooling-adjustable and classic pods, LOST MARY X-LINK adds sweetness-adjustable and nicotine-strength-adjustable pods, expanding the compatible pod types to four.
- High-Spec Core Parameters
X-LINK features 12 ml e-liquid capacity, up to about 20,000 puffs, a 1100 mAh battery, dual-mesh coils, a 2.25-inch TFT display, and two-level airflow adjustment.
- Region-Differentiated Market Strategy
Korean JOINOne packaging is labeled 0.98% synthetic nicotine, indicating that Aiqiji (Shenzhen) Technology Co., Ltd. is pursuing differentiated product strategies to meet regulatory requirements in each market.
2Firsts, December 1, 2025 — 2Firsts has observed that e-cigarette brand LOST MARY recently launched the “X-LINK” series on its Russian-market website. The series largely mirrors ELFBAR’s earlier JOINOne lineup, while adding pods with sweetness control and nicotine-strength control.
2Firsts has compiled the key specifications of the LOST MARY X-LINK series, as shown in the chart below.
X-LINK and JOINOne: Largely Overlapping Lineups
In July 2025, ELFBAR announced the JOINOne series on its website. The series includes “Dock-to-Vape” and “Standalone Use” pods, both supporting three levels of cooling adjustment. Battery devices include the screen-equipped Dynamic Device and the screen-less Lumeo Device; both support three power levels.
In November 2025, ELFBAR launched the JoinOne15 Classic prefilled pod kit in the UK, adopting a “2 ml prefilled pod + 10 ml refill container (‘2+10’)” structure, which has since been added to the JOINOne lineup on ELFBAR’s website.
The X-LINK series on LOST MARY’s Russian website looks highly consistent with ELFBAR JOINOne and spans two of the same items from the JOINOne lineup:
- “Standalone Use” pod
- Dynamic Device with display
Among them, the Standalone Use pod contains its own battery and can be used independently; the Dynamic Device features a 2.25-inch TFT display.
Notably, in addition to the original cooling-adjustable pod and classic pod, LOST MARY X-LINK adds sweetness-adjustable and nicotine-strength-adjustable pods, bringing the total compatible pod types to four.
Four Compatible Pod Types: Cooling, Sweetness, Nicotine, Classic
As for other specs, the LOST MARY X-LINK kit measures 52 × 94 × 24.5 mm. Pod sizes are 31 × 93 × 24.5 mm and 27.7 × 94 × 24.5 mm. E-liquid capacity is 12 ml, with a claimed maximum of about 20,000 puffs, equivalent to roughly 1,666 puffs per ml.
Nicotine strength is 20 mg/ml. The device houses a 1100 mAh battery and dual-mesh atomizer. The battery device features a 2.25-inch TFT screen and supports two-level airflow control.
From Russian vaping news sites, 2Firsts found that the LOST MARY X-LINK series has appeared in the local market since May of this year. Sites including vivalacloud and belvaping have posted hands-on reviews. At that time, the available pod options were limited to the sweetness-adjustable pod and the classic pod.
Korean JOINOne Packaging Shows 0.98% Synthetic Nicotine
While reviewing JOINOne information, 2Firsts noted that ELFBAR’s website displays both Korean and English packaging for JOINOne. The Korean version explicitly states that the product uses 0.98% synthetic nicotine (0.98% 합성니코틴).
These products indicate that Aiqiji (Shenzhen) Technology Co., Ltd. is pursuing a globally differentiated product strategy tailored to regional regulatory variations.
