Best Vapor Cups [2026]: Vapor from Glass Compared
Vapor from a glass: how a vapor cup works
A vapor cup vaporizes concentrate or the oil from a 510 cartridge and channels the vapor into a glass cup. From the cup you drink the vapor in small sips rather than drawing it directly from a mouthpiece. The vapor cools inside the glass, and the cup can be passed around without everyone drawing from the same mouthpiece.
The list below shows the vapor cups from our daily price comparison, from Zenco through Tronian and O.Pen to Pulsar. Results are sorted by the number of shops stocking each model. Prices and availability update automatically.
Three Vapor Cups by Use Case
Our selection is based on the manufacturer information linked below, as of 2026-10-04. It is not our own comparison test. Choose based on glass design and preferred connection type; the number of shops in the full price grid is not a quality rating. Check the product page for offers available in your shipping country.
Zenco Uno: if you’re looking for a cup without a water glass
The Uno fills its glass cup automatically and supports 510 cartridges as well as the designated heating heads. It suits you if you want to use the cup without adding water. Limitation: The four settings are voltage levels, not degree-precise temperatures. Check what heating heads are included with the offer. Manufacturer information.

Zenco Flow: if a water glass is important to you
The Flow adds a glass attachment with water function to the automatic cup fill. It is the more appropriate Zenco option if this specific design is what you want. Limitation: The water glass needs to be filled, emptied, and cleaned separately. We do not derive any measured flavor or cooling winner from this. Manufacturer information.

Tronian Omegatron: if you want to use concentrates with a glass heating core
The Omegatron uses a heating core the manufacturer calls a Glass Core and also supports 510 connections. It is an alternative if this heating head concept matters to you. Limitation: The glass cup and heating core are separate parts with different maintenance needs; check the availability of compatible replacement parts before buying. Manufacturer information.

Why Vapor Cups?
A Vapor Cup captures the vapour in a glass, instead of sending it straight through a mouthpiece. You sip at your leisure, the vapor cools in the glass, and the cup can be passed around the table.

What to look for when buying a vapor cup
- Concentrate, cartridge, or both: Some vapor cups accept only dabs, others also have a 510 thread for oil cartridges. If you use both, a device with both inputs saves you buying a second one.
- Glass and replacement parts: Check whether compatible replacement glass is available. Glass can break and needs protection during transport.
Would you rather dab the traditional way? Then an e-rig is a better fit. For cartridges on the go, a 510 Vape Pen does the job.

Can I use oil cartridges in a vapor cup?
That depends on the model. Some vapor cups have a 510 thread and accept standard oil cartridges; others are built for dabs only. You will find the relevant details on the individual product page.
