Zenco Duo Vapor Cup Vaporizer
The Zenco Duo is a premium tabletop vaporizer that completely reimagines the way you enjoy vapour. Instead of inhaling directly through a traditional mouthpiece, the Zenco Duo automatically fills a glass cup with vapour, allowing you to lift the glass and sip from it like a drink.
Combining innovative technology with elegant design, the Zenco Duo creates a distinctive experience that is ideal for concentrate enthusiasts, 510 cartridge users and customers who enjoy sharing sessions with friends.
The device features a powerful 2200mAh rechargeable battery, four adjustable voltage settings and a built-in fan that automatically transfers vapour into the glass positioned above the base.
Simply connect a compatible 510 cartridge or one of the included concentrate coils, select your preferred voltage and activate the filling system. The Zenco Duo does the rest, producing vapour that collects inside the glass ready for you to enjoy.
Unlike conventional concentrate vaporizers, there is no need to inhale directly from a hot mouthpiece or draw through a water pipe.
Instead, the Zenco Duo delivers vapour into a removable glass, creating a unique and enjoyable tabletop experience.
Each Zenco Duo includes two specially designed glass cups, making it particularly convenient for sharing or alternating between glasses.
The package also includes two concentrate coils – one ceramic and one quartz – providing different heating options for compatible concentrates.
With four voltage settings ranging from 2.5V to 4.0V, the Zenco Duo allows you to adjust the heating intensity to suit your cartridge or concentrate.
The device also features both manual and automatic filling modes, giving you control over how much vapour is collected in the glass.
Its interchangeable, dishwasher-safe glassware and removable food-grade silicone diffuser make cleaning and maintenance straightforward.
Available in a selection of attractive finishes, the Zenco Duo combines the appearance of a premium home accessory with the functionality of a versatile concentrate vaporizer.
For customers seeking something different from conventional dab pens, electronic rigs and 510 batteries, the Zenco Duo offers one of the most distinctive vaporization experiences available.

Revolutionary Glass-Filling Vaporizer
The standout feature of the Zenco Duo is its innovative glass-filling system.
Traditional vaporizers require you to inhale directly through a mouthpiece, stem or water pipe.
The Zenco Duo takes a completely different approach.
Instead of drawing vapour through a conventional mouthpiece, the device uses a built-in fan to transfer vapour from the heating system into a specially designed glass cup.
Once the glass has filled, simply lift it away from the base and sip the vapour.
How Does the Zenco Duo Work?
The process is simple.
- Connect a compatible 510 cartridge or concentrate coil.
- Place the glass on top of the Zenco base.
- Select your preferred voltage.
- Activate manual or automatic filling.
- Allow the glass to fill with vapour.
- Remove the glass and enjoy.
Benefits of the Vapor Cup Design
Unique experience: Enjoy vapour from a glass rather than a conventional mouthpiece.
Automatic filling: The built-in fan transfers vapour into the cup.
Ideal for sharing: Two glasses are included.
Comfortable use: No need to draw directly through a small mouthpiece.
Premium presentation: An attractive addition to a tabletop setup.
Versatile operation: Suitable for compatible cartridges and concentrate coils.
Is the Zenco Duo a Traditional Vaporizer?
The Zenco Duo uses vaporization technology, but its delivery method is different.
Instead of directing vapour immediately into your mouth, it collects the vapour inside a removable glass.
This makes it particularly appealing to customers who want a more relaxed, social or visually distinctive experience.
Automatic Glass Filling
The Zenco Duo features an integrated fan that transfers vapour into the glass.
This is one of the features that separates it from conventional concentrate vaporizers.
What Is Automatic Filling?
Automatic filling allows the device to operate without continuously holding down the heating button.
Once activated, the Zenco Duo heats the connected cartridge or coil and transfers vapour into the glass.
Benefits
Hands-free operation: Convenient automatic filling.
Consistent process: The fan handles vapour transfer.
Easy sharing: Fill a glass and pass it to another user.
Convenient control: Stop the filling process when you have collected enough vapour.
Does the Zenco Duo Fill the Glass Instantly?
The device offers rapid heating, but the time required to fill a glass depends on the voltage, heating attachment, material and desired vapour density.
Can You Stop Filling Early?
Yes.
You can stop the automatic filling process when the glass contains your preferred amount of vapour.
Manual and Automatic Heating Modes
The Zenco Duo offers two ways to operate its heating and filling system.
Manual Mode
Press and hold the power button to activate heating and vapour production.
Release the button when you want to stop.
Best for: Customers who want direct control over the filling process.
Automatic Mode
Double-click the power button to activate automatic filling.
The device continues operating until the filling cycle is stopped.
Best for: Customers who prefer a more convenient, hands-free experience.
Which Mode Is Better?
Both modes use the same heating system.
Manual mode provides more direct control, while automatic mode is more convenient for filling a glass without continuously holding the button.
Our Recommendation
Start with manual mode while learning how the Zenco Duo works.
Once familiar with your preferred voltage and attachment, automatic mode is particularly convenient.
Four Adjustable Voltage Settings
The Zenco Duo features four voltage settings, allowing you to adjust heating intensity.
| Setting | Indicator | Voltage | Suggested Use |
|---|---|---|---|
| Low | Yellow | 2.5V | Lower-intensity heating |
| Medium | Blue | 3.0V | Balanced heating |
| Medium-High | Green | 3.5V | Stronger vapour production |
| High | Red | 4.0V | Maximum available voltage |
2.5V – Low
The lowest setting is a sensible starting point for compatible 510 cartridges.
Lower voltage may help preserve flavour and reduce overheating.
3.0V – Medium
A useful setting for customers seeking a balance between flavour and vapour production.
3.5V – Medium-High
Provides increased heating intensity for suitable attachments and formulations.
4.0V – High
The highest available setting delivers maximum voltage.
This setting should only be used with cartridges or coils designed to tolerate it.
How Do You Change the Voltage?
Press the power button three times to cycle between the four voltage settings.
Does the Zenco Duo Have Precise Temperature Control?
No.
The Zenco Duo uses adjustable voltage rather than direct temperature control.
The actual heating temperature depends on the attached coil or cartridge and its electrical characteristics.
What Voltage Do We Recommend?
For compatible 510 oil cartridges, begin with 2.5V and increase gradually if appropriate.
For the included concentrate coils, follow the manufacturer's instructions and adjust according to the material and heating attachment.
Do not assume that every cartridge is suitable for 4.0V operation.
Compatible With 510 Thread Cartridges
One of the Zenco Duo's biggest advantages is its 510-thread compatibility.
This allows the device to work with many suitable oil cartridges.
Instead of inhaling directly from the cartridge's mouthpiece, the Zenco Duo collects the vapour inside the glass.
Benefits of 510 Compatibility
Greater versatility: Use suitable prefilled or refillable oil cartridges.
Convenient operation: No separate cartridge battery required.
Adjustable voltage: Four available heating settings.
Unique vapour delivery: Cartridge vapour collects inside the glass.
Which Cartridges Can You Use?
The Zenco Duo may be compatible with appropriately sized and electrically suitable 510 cartridges, including selected models from:
CCELL: TH2 EVO, Kera and Vita ranges.
Other 510 cartridge manufacturers: Where dimensions and electrical requirements are compatible.
Does Every 510 Cartridge Fit?
No.
The cartridge must fit within the Zenco Duo's attachment area.
Some wider or unusually shaped cartridges may not be compatible.
Does the Zenco Duo Work With CCELL Cartridges?
Many standard-sized CCELL 510 cartridges may be suitable.
However, larger-capacity cartridges, including wider 2ml models, should be checked for physical fit.
What Is the Best Voltage for CCELL Cartridges?
Start with a low compatible setting, such as 2.5V, and increase only if the cartridge and formulation permit it.
Can You Use Disposable Vape Pens?
The Zenco Duo is designed for compatible 510-thread attachments.
Self-contained disposable vape pens cannot normally be connected directly.
Two Concentrate Coils Included
The Zenco Duo includes two concentrate coils, providing different heating options.
These are:
1 × Ceramic Concentrate Coil
1 × Quartz Concentrate Coil
Both connect to the device using its compatible heating attachment system.
Why Include Two Coils?
Different heating materials can provide different characteristics.
Ceramic is valued for its thermal properties and relatively even heating.
Quartz is valued for its responsiveness and direct heating characteristics.
Ceramic Coil
The ceramic coil is designed for compatible concentrates.
Its heating surface offers a practical alternative to exposed quartz elements.
Quartz Coil
The quartz coil provides another option for vaporizing suitable concentrates.
It may respond differently to heating depending on the material and operating voltage.
Which Coil Is Better?
The best choice depends on the concentrate and your preferred heating characteristics.
Customers who prioritise flavour may prefer one attachment, while those seeking more intensive vapour production may prefer another.
We recommend trying both at appropriate settings.
Can You Replace the Coils?
Yes.
Compatible replacement coils are available separately.
Are the Coils Included in the Standard Package?
Yes.
The standard Zenco Duo package includes one ceramic and one quartz concentrate coil.
Concentrate Compatibility
The Zenco Duo is particularly well suited to compatible concentrate formulations.
The included concentrate coils allow it to vaporize suitable extracts without requiring a separate 510 oil cartridge.
Suitable Concentrates
Depending on the selected coil and formulation, suitable materials may include:
- Wax
- Budder
- Crumble
- Rosin
- Resin
- Other compatible concentrate extracts
Can You Use Solid Concentrates?
Yes.
The included concentrate coils are designed for suitable solid or semi-solid concentrates.
Can You Use Live Resin?
Suitable live resin concentrates may be used with the appropriate heating attachment.
Can You Use Live Rosin?
Suitable live rosin concentrates may also be used.
Can You Use Shatter?
Appropriately sized amounts of shatter may be compatible with the concentrate coils.
How Much Concentrate Should You Load?
Start with a small amount.
Overloading the coil may cause residue build-up, inefficient heating or leakage.
Is the Zenco Duo Better Than a Dab Pen?
The Zenco Duo offers a more distinctive tabletop experience.
A conventional dab pen is smaller and more practical for use away from home.
Customers who prioritise portability may prefer a Puffco Pivot or Yocan concentrate pen.
Dry Herb Compatibility – Important Considerations
Zenco advertises the Duo as compatible with dry herbs as well as concentrates and 510 cartridges.
However, dry herb use requires the appropriate heating attachment and careful technique.
Can You Vape Dry Herbs With the Zenco Duo?
The manufacturer lists dry herb compatibility.
However, the standard concentrate coils are not equivalent to a dedicated dry herb heating chamber.
Does the Zenco Duo Include a Dedicated Dry Herb Chamber?
The standard package includes a ceramic concentrate coil and a quartz concentrate coil.
It does not include a separate, dedicated dry herb vaporizer chamber.
Is the Zenco Duo a Good Dry Herb Vaporizer?
For customers whose main priority is dry herb vaporization, we recommend a dedicated dry herb vaporizer.
Devices such as the XMAX V3 Pro, Arizer Solo 3 V2 or Storz & Bickel Mighty+ offer heating systems designed specifically for dry herbs.
Can Dry Herbs Combust?
Yes.
Direct-contact coil heating can cause combustion if unsuitable material or heating techniques are used.
Customers should not assume that every herb attachment provides controlled, combustion-free vaporization.
Our Recommendation
Choose the Zenco Duo primarily for concentrates and suitable 510 cartridges.
If dry herbs are your main priority, a dedicated dry herb vaporizer will generally offer more consistent temperature control and extraction.

Zenco's compatible glassware is designed to be interchangeable across supported Zenco devices.
Can You Buy Replacement Glasses?
Yes.
Compatible replacement and alternative Zenco glassware is available separately.
Are the Glasses Made From Real Glass?
Yes.
The Duo uses purpose-designed glassware rather than disposable plastic cups.
Can You Use an Ordinary Drinking Glass?
We recommend using genuine compatible Zenco glassware.
Ordinary drinking glasses may not fit or seal correctly against the diffuser.

A separate mains power adapter should not be assumed to be included.
Premium Tabletop Design
The Zenco Duo is designed to be displayed rather than hidden away.
Its combination of a sculpted base and removable glass creates an appearance closer to a premium home accessory than a conventional vaporizer.
Available Finishes
The Zenco Duo range is offered in several finishes, including:
Onyx: Dark, understated appearance.
Wood: Natural wood-inspired finish.
Leaf: Green-inspired finish.
Stone: Neutral grey-inspired finish.
Availability depends on the retailer and production batch.
Is the Zenco Duo Portable?
The device is cordless and can be moved between locations.

DopeVapes Expert Verdict
The Zenco Duo is one of the most distinctive concentrate vaporizers available, offering a completely different experience from traditional dab pens and electronic rigs.
Its biggest attraction is the innovative glass-filling system.
Rather than inhaling directly from a mouthpiece, the Duo collects vapour inside a glass, allowing you to lift it and sip.
It's a clever concept that makes the Zenco Duo particularly enjoyable for home use and sharing.
We also like the inclusion of two glass cups.
This makes the Duo more practical than single-glass alternatives, especially for customers who want to share sessions or keep a clean spare available.
The four voltage settings provide useful flexibility, while the automatic filling mode makes the device convenient to operate.
Another advantage is its 510 cartridge compatibility.
Customers can use suitable oil cartridges as well as the included ceramic and quartz concentrate coils, giving the Duo greater versatility than many dedicated concentrate rigs.
The 2200mAh battery provides cordless operation, and the dishwasher-safe glassware makes cleaning considerably easier.
However, the Zenco Duo does have limitations.
It is primarily a tabletop device rather than a pocket-friendly portable vaporizer.
Its voltage-based heating system also does not provide the precise temperature control available from premium electronic dab rigs.
Although Zenco advertises dry herb compatibility, we would not recommend the Duo as a first choice for customers whose main priority is dry herb vaporization.
For dry herbs, dedicated devices such as the XMAX V3 Pro or Arizer Solo 3 V2 are better suited to the task.
For concentrates and compatible 510 cartridges, however, the Zenco Duo offers something genuinely different.
Our Recommendations
Best for unique vapor cup experience: Zenco Duo.
Best for precise concentrate temperature control: Dr Dabber Switch 2.
Best premium electronic dab rig: Puffco Peak Pro.
Best portable concentrate pen: Puffco Pivot.
Best affordable 510 cartridge battery: CCELL Stylo.
Our verdict: The Zenco Duo is an innovative tabletop vaporizer combining automatic glass filling, two included glasses, four voltage settings, 510 cartridge compatibility and ceramic and quartz concentrate coils. An excellent choice for concentrate enthusiasts who want a stylish, versatile and genuinely different vaporization experience.
