The Cloutank M4, by Cloupor, is a dual-use atomizer suitable for both dried herbs and herbal concentrates! Like its predecessor, the Cloutank M3, the M4 is built to look like an e-cigarette tank atomizer, and works on any 510 threaded battery. The design is far smoother than the M3, with a wider and less convoluted interior. The base is also compacted, increasing its resemblance to tanks for vaping eLiquid. Overall, the Cloutank M4 is a wonderful upgrade on the M3, and is the best discreet herbal vaporizer available!

What’s the Cloutank M4 Dual Use Atomizer?

With two different atomizer heads, one for concentrates and one for dry herbs, the Cloutank M4 is a highly versatile atomizer! It also has an airflow adjustment ring, giving you additional control over your vape. Stainless steel and Pyrex glass are used in its construction, making it a strong and sturdy device! The multi-filter system also cleans the vapor, preventing particles of plant matter from entering your mouth. This is a powerful and reliable vaporizer, great for taking out and about, especially since it has the same connector as most eLiquid tanks! For more information on using the M4, read our guide!
