Dynavap shook up the cannabis world in 2016 when their battery-free dry herb vaporizer burst onto the scene and became one of the most popular portable vapes. Dynavap launched the “B” in 2022 and did it again. The Dynavai B is a silicone stemmed version of their popular Vapcap vaporizer with a simplified design and an easier-to-use interface.
The B is about the size of a small joint. It’s a battery-free vaporizer that uses a small torch to an induction heater to provide heat. This vape is pocket-friendly and natively fits a 10mm glass bong.

I’ve ranked the B a 9 out of 10 overall. It has exceptional vapor potency for a microdose-sized bowl. This Dynavap tip is also designed to fully extract its bowl with a single heat cycle, and there’s no need to rotate the vape in your hand while torching.
The Dynavap B is ranked 20th of 45 on my list of 2025’s Best Portable Vaporizers. Click Here to see the complete list.

Load the tip of the vaporizer by removing the cap and packing the bowl with flower. Whole nug or ground will work. The B holds .08-.12g of cannabis. Slip the cap back on when your bowl is packed, and you’re ready to vape.
Heat the Dynavap B by aiming the torch at the lower facets beneath the cap. When the Cap clicks, stop torching and start vaping.

Thoughts on Silicone
I have mixed feelings for silicone. I’m not a fan of the soft silicone bongs and bubblers. The brightly colored bongs often smell funny and feel funny when you hit them.
Dynavap did a fantastic job sourcing quality silicone and properly curing it to avoid nasty smells and tastes.
I can’t taste *ANY* abnormal tastes with the Dynavap “B,” – which is understandable since the vapor path is 100% stainless steel. There is no silicone in the vapor path.
Still, I don’t expect the silicone body to last forever, especially with regular exposure to sunlight and isopropyl alcohol. It’ll probably last longer than some of the wooden stems, though!
The Dynavap B is only $39, an incredible value. This vaporizer will last a lifetime, and someday, your grandkids could be using an antique Dynavap B that was passed down to them.
Seriously, though, it’s silicone and stainless steel. The vapor only touches stainless steel. Your fingers only touch silicone.
It’s easier to heat and use than all of the other Dynavap vaporizers, and it’s cheaper.
This is a great first vape for casual smokers and first time vaporizer users.
