Zenco Duo review: Everything you need to know

Thanks to vapor cups like the Zenco Duo, you can drink your weed vapor now. Turn your favorite flower, dabs, and vape carts into full glasses of “Oh, that's fire. What strain is that?!”

Learn about the unique Zenco Duo device, how it works, and what you can expect when using it.

What is the Zenco Duo?

Zenco sells shareable tabletop vaporizers that allow you to consume weed using vapor cups. Vapor cups are exactly what they sound like — cups full of vapor you can “drink.”

Zenco produces two primary products: the Zenco Flow and the Zenco Duo. Both devices use cannabis flower, concentrates, and 510-thread cannabis vape cartridges. The difference between the two Zencos is water. The Zenco Flow has a water filtration system, while the Zenco Duo is a dry-hit experience. Both devices cost $249.

With the Zenco Duo, you'll receive:

  • Zenco Duo
  • 2 water glasses 
  • 2 vapor coils (one ceramic, one triple quartz) 
  • USB charger 
  • Concentrate scoop 
  • Cleaning brush

The Zenco Duo comes in four styles: Wood, Onyx (black), Stone (gray), or Leaf (green). It contains a removable food-grade silicone diffuser powered by a 2200 mAh battery.

Zenco's features include heating variability, interchangeable glasses, an automatic filling system, haptic vibration, and compatibility with every cannabis product — save for edibles.

Zenco offers a 1-year limited manufacturer's warranty.

Zenco Duo's performance and experience

In terms of using the Zenco device, the ease of use wins. It's simple to double-click a button and wait for the cup to fill. Then you sip the vapor, lather, rinse, and repeat until you've reached your desired zootage. There are a bunch of Zenco accessories you can purchase, too, like the Cafe glass, To-Go glass, and the Sommelier glass.

Typically, with varying temperatures, the higher the temperature, the bigger the vapor clouds, but since you're filling up an actual container, the chase for big clouds won't matter. 

Fill it up to however much vapor you want. For a standard temperature across the board, I found the Yellow and Green settings to be just fine for the products I used. That aside, the device charges fast, heats instantly, the vapor is produced consistently — and you will definitely be stoney by the end of your session.

I used the devices with some Super Lemon Haze flower from Panacea, some Alien Mints rosin from Alien Labs x Kalya, and a Zkittlez Cake live resin cart from Jungle Boys at each setting. In the end, they all got me damn high while reinforcing the lower-voltage-to-bigger-flavor standard of using vaporizers — the highest temperature (red) did a lil' bit of a cook job on my dabs.

How to use the Zenco Duo

Most electronic devices are pretty damn easy to use, and the Zenco products are no different.

With the Zenco Duo, you can sip slowly and enjoy your vapor like when drinking a cocktail at happy hour. 

Step 1: Charge device

Charge your device for two hours before your first use. The light will change to green when it's fully charged.

Step 2: Add cannabis product

Remove the magnetic top from your Zenco Duo base and add whatever cannabis you will use. The device comes with two different vapor coils that can be used with flower or extracts. 

If you're using herb, use the triple quartz vapor coil. If you're using concentrates, use the ceramic vapor coil. If you're using a 510-thread cartridge, you don't need either of these coils — just twist it into the base.

Step 3: Lock Zenco glass into place

Replace the magnetic top for the base and lock the glass onto the top of it.

Step 4: Power on

Click the main button five times to turn on the device.

Step 5: Choose temperature

Click the button three times to cycle between the four preset temperatures: 

  • Yellow/Low: 2.5V 
  • Blue/Medium: 3.0V 
  • Green/Medium-High: 3.5V
  • Red/High: 4.0V

Like when using a vaporizer battery, the device is instantly ready for consumption after choosing a power setting. Just click and hit.

Step 7: Fill glass with vapor

You can manually fill the glass by pressing and holding the main button or tap twice, which will automatically fill the glass. If you want to stop it before the glass is full, tap the button once.

Step 8: Inhale 

Inhale the vapor, get high, and love life. It's that simple. For a smoother experience, the brand recommends using a straw.

How to clean the Zenco Duo

Remove the silicone diffuser and place the glass in the dishwasher for quick cleaning. The silicone diffuser can be washed with dish soap.

For a deeper cleaning, start by removing the silicone diffuser from the device. The Duo's glass can be wiped with an Isopropyl cotton ball or pad on the inside of the glass. 

Do not add water or ice to the Duo, as it will leak into the unit, causing permanent damage.

Bottom line

Overall, the Zenco Duo works great — it's easy to use, and the glass fills with vapor pretty damn fast. You'll be ready to sip your weed in just a few seconds. 

It looks good, is well-made, delivers high functionality, lets you get the most out of various cannabis products, and you will indeed feel high off just a couple of vapor cups.
