2Firsts has noted that e-cigarette brand MASKKING recently listed a new device on its official website: MASKKING UCEE MAX. The product adopts an open-system design. The brand claims a 10 mL e-liquid capacity, supports three refills, and claims a total of 60,000 puffs.

Refillable three times | Claimed 60,000 puffs

2Firsts has compiled the specification information for the MASKKING UCEE MAX, as shown below:

In terms of specifications, MASKKING UCEE MAX, positioned as an open-system refillable device, measures approximately 46.8 × 22.9 × 97.3 mm and has a 10 mL reservoir. It also states “at least 3 refills, cumulative maximum about 30 mL,” and the official claimed total puff count is 60,000. Based on product images published on the official website, the nicotine strength is 50 mg/mL, and the device uses a top-fill design.

The device uses a 0.6Ω dual mesh coil (Dual Mesh), is powered by a 650 mAh built-in battery, and supports Type-C charging. Structurally, it features a visible pod for monitoring e-liquid levels, and the website materials also show Normal/Boost dual modes, a child-lock icon, and a rotating seal feature.

MASKKING UCEE upgrade: puff count, battery, and coil adjustments

Notably, 2Firsts observed that as early as late 2023, MASKKING launched an open-system refillable device named “MASKKING UCEE,” whose exterior design is highly similar to that of the UCEE MAX.

According to the UCEE product page, the device claims 7,000 puffs, has a 600 mAh battery with Type-C charging, and a 12 mL reservoir. The kit additionally includes 15 mL of e-liquid. Nicotine strength options are listed as 2% and 5%, and the coil resistance is 1.0Ω. The device size is 81.4 × 44.5 × 22.6 mm, with a weight of 46 g.

Comparing MASKKING UCEE with MASKKING UCEE MAX, the “upgrades” of UCEE MAX are mainly reflected in:

• Higher claimed puff count: UCEE claims 7,000 puffs; UCEE MAX claims 60,000 puffs.

• Atomization specification adjustment (lower resistance + dual mesh): UCEE is stated at 1.0Ω; UCEE MAX is stated at 0.6Ω Dual Mesh.
• Slightly larger battery capacity: UCEE is 600 mAh (Type-C); UCEE MAX is 650 mAh (Type-C).

• More explicit mode/power information: The UCEE MAX page explicitly shows “Normal / Boost” dual modes (Dual Power Boost Mode), while the UCEE specification section does not provide mode information.

• Differences in refill and structural presentation:

Capacity: UCEE lists a 12 mL reservoir and includes 15 mL e-liquid in the kit; UCEE MAX lists a 10 mL reservoir and states “at least 3 refills, maximum about 30 mL.”

Operation/structure: UCEE MAX materials show a rotating mouthpiece/seal and a bottom slider for power-on; UCEE’s instructions describe opening a silicone plug to refill, waiting 2 minutes, and pressing the button three times to power on/off.

At present, MASKKING UCEE MAX has been listed on the brand’s official website and has also been promoted on the brand’s official Instagram and other social media platforms.
