MYDE MIOU 2-in-1 60K: Product Design Of High-Capacity E-cigarettes Through The Lens Of Dual-Reservoir Architecture
Aug 15, 2026
In the realm of high-capacity e-cigarette products, ever-increasing puff counts are nothing new. What truly reflects the product's design philosophy is how the device manages the interplay between e-liquid storage, atomization, battery power, and user operation as capacity grows. The MYDE MIOU 2in1 60K employs a representative dual-reservoir approach; designed for a capacity of approximately 60,000 puffs, it integrates two 20mL e-liquid reservoirs, dual mesh coils, and a rechargeable battery into a cohesive hardware structure.
1. "2in1" is more than just a simple capacity boost

The most noteworthy feature of the MYDE MIOU 2in1 60K is the "2in1" designation in its name.
According to available information, the device comes pre-filled with 40mL of e-liquid, distributed across two 20mL reservoirs. Unlike traditional single-reservoir devices, this design houses two separate storage units within a single chassis.
The significance of the dual-reservoir structure extends beyond merely increasing liquid capacity. Managing two storage zones requires careful consideration of spatial layout, atomization components, circuitry, and airflow pathways, thereby placing higher demands on the internal design.
From a user perspective, the 2in1 structure allows for varied usage patterns centered around the two reservoir units. Specific switching methods and the operational logic between the two reservoirs should be verified against the actual product specifications.
2. What does "60,000 Puffs" signify?
Another key specification of the MYDE MIOU 2in1 60K is its rating of approximately 60,000 puffs.
While "puffs" typically describe a device's theoretical capacity, this figure does not translate to a fixed duration of personal use. Factors such as puff duration, usage frequency, and operating conditions all influence the actual consumption of e-liquid and battery power.
Therefore, the "60,000" figure serves best as a reference for the product's capacity tier.
From a design standpoint, a high nominal capacity requires synergy between the e-liquid storage and power systems. The MYDE MIOU combines 40mL of e-liquid with a 600mAh rechargeable battery, demonstrating that the design focuses not merely on a capacity number, but also on the device's sustained operational needs.
3. 40mL pre-filled design
The pre-filled e-liquid system is a crucial structural element of this type of product. The MYDE MIOU 2in1 60K features a total of 40mL of pre-filled e-liquid, configured as two separate 20mL reservoirs. This pre-filled design means the device comes with the e-liquid already loaded, resulting in a relatively sealed product structure.

The dual 20mL design creates distinct zones for the e-liquid storage. Compared to a single 40mL chamber, the dual 20mL unit setup differs in terms of product architecture and operational logic.
From a manufacturing perspective, the dual-chamber design requires addressing challenges such as sealing, circuit connections, and atomization synchronization-all practical factors that impact device reliability.
4. Dual Mesh Coils Complement the Structure
For the atomization system, the MYDE MIOU 2in1 60K utilizes two 1.2Ω mesh coils.
In terms of specifications, the dual-coil configuration aligns with the dual-chamber design. Mesh coils employ a mesh-like heating element, offering different heating surface areas and structural characteristics compared to traditional wire coils.
In a dual-chamber device, the atomization assembly must not only vaporize the e-liquid but also function effectively in coordination with the two storage units.
Consequently, the coil specifications cannot be viewed in isolation from the rest of the device. Actual atomization performance is also influenced by power control, e-liquid formulation, airflow, and the device's internal structure.
5. 600mAh Battery Provides Continuous Power

The MYDE MIOU 2in1 60K is powered by an internal, rechargeable 600mAh battery.
For pre-filled products, there must be a proper balance between battery capacity and the device's usage lifespan. Given the large e-liquid capacity, a non-rechargeable battery might run out of power before the e-liquid is fully consumed.
To address this, the MYDE MIOU features a rechargeable design, allowing the battery to be replenished as needed.
The device charges via a USB Type-C port-a standard interface widely used in smartphones, headphones, and other portable electronics. Note that, according to available information, the charging cable is not included in the package.
6. LED Screen Provides Information Feedback
Many disposable e-cigarettes in the past relied on simple indicator lights, making it difficult for users to accurately gauge the device's current status. The MYDE MIOU 2in1 60K features an added LED display screen.
The screen primarily serves to provide information feedback. For high-capacity devices, the ability to view the device's status directly eliminates the need for users to rely solely on intuition or feel during operation.
However, current product documentation does not explicitly list everything the screen displays; therefore, it is advisable to refer to the actual interface upon the product's official release to avoid overstating the display's capabilities.
7. Adjustable Airflow leads to structural changes

The airflow system is another key feature of the MYDE MIOU 2in1 60K.
The device supports adjustable airflow, indicating that the air intake system is not fixed.
Airflow volume affects draw resistance and alters the mixing ratio of air and vapor. Since user preferences regarding airflow vary, an adjustable design offers flexibility.
It is important to note, however, that airflow adjustment is not the same as power adjustment; they are distinct device parameters. Actual performance depends on a combination of factors, including coil resistance and device output.
8. Multiple nicotine concentration versions available
According to available information, the MYDE MIOU 2in1 60K comes in nicotine concentrations of **0%, 2%, 3%, and 5%**.
This detail must be clearly specified in product documentation, as regulations regarding nicotine concentration, sales methods, packaging labeling, and age restrictions vary by market.
Consequently, when creating product catalogs or export documentation, one should not rely on a single, uniform parameter but rather verify product labels against specific batches and sales regions.
As nicotine is addictive and subject to regional regulations, actual sales and usage must comply with local laws and regulations.
9. Product differentiation driven by the 2-in-1 design

When comparing the MYDE MIOU 2in1 60K to standard single-chamber products, the primary difference is not merely its 60,000-puff capacity.
The most notable feature is its design, which incorporates dual e-liquid reservoirs, dual coils, and dual airflow channels.
This structure results in an internal layout distinct from traditional single-chamber devices and imposes higher technical requirements during product development. Externally, the user sees a single, complete device; internally, however, it comprises several interconnected modules, including the e-liquid reservoir, battery, atomization system, airflow mechanism, and display.
10. A Holistic View of Specifications
The specifications of the MYDE MIOU 2in1 60K do not exist in isolation.
The 60,000-puff rating reflects the product's capacity positioning;
The 40mL e-liquid volume provides the reservoir foundation;
The 20mL x 2 configuration embodies the dual-chamber structure;
The 1.2Ω x 2 mesh coils correspond to the dual atomization components;
A 600mAh battery supplies power;
A Type-C port handles recharging;
An LED screen provides status feedback;
Adjustable airflow offers flexibility in draw control.
When these specifications are viewed together, it becomes clear that the product's design focus is not on any single parameter, but rather on establishing a comprehensive hardware ecosystem centered around the 2in1 structure.
Summary
In terms of structure, the MYDE MIOU 2in1 60K is a high-capacity vape characterized primarily by its dual-chamber design. The 40mL of pre-filled e-liquid is distributed across two 20mL chambers and paired with dual 1.2Ω mesh coils, creating a direct correspondence between the reservoir and atomization systems.

A 600mAh rechargeable battery and Type-C port handle power needs, an LED screen provides status feedback, and adjustable airflow offers flexibility in the user experience.
While the device is rated for 60,000 puffs, actual usage may vary based on individual habits. For product documentation, wholesale catalogs, or export paperwork, it is advisable to verify-in addition to hardware specifications-details such as packaging dimensions, nicotine concentration, labeling information, and regulatory requirements for target markets.
From an overall design perspective, the MYDE MIOU 2in1 60K is defined by the combination of "dual chambers, dual mesh coils, rechargeability, a display screen, and adjustable airflow." This combination is far more significant to understanding the product's structure than simply focusing on the "60,000" puff figure.
