C37 CBD Vape Pen | 330mAh | 0.5ml | Adjustable Airflow + LED Screen | OEM & ODM

Here is a fact we have learned from years of filling customer orders: the same oil tastes different in different devices, and the difference is usually airflow. A tight draw concentrates the vapor and amplifies flavor; an airy draw cools it down and smooths it out. Most disposable CBD pens pick one airflow and force every customer into it. The C37 gives the user a real airflow controller, and that single feature changes the product from “a pen” into “my pen.”

The C37 carries a 330mAh cell – noticeably larger than the 280mAh standard across most of the category. Why? Because an airflow-adjustable device invites longer sessions. A user who tunes their draw and finds their sweet spot will hit the device more often than a user on a fixed-draw pen. If the battery dies after 150 puffs, the experience ends in disappointment. The 330mAh cell, combined with the 2.0/2.6Ω coil options, gives the C37 the stamina to match its engagement.

The LED screen shows battery level and puff count. The button handles power on/off. On a 0.5ml device the screen is a surprise – buyers expect that feature set on bigger devices, and the C37 delivers it in a 102mm pen. The UI can carry your logo animation and brand colors, which turns every device into a small brand broadcast. If you have ever watched a shelf comparison between a screened device and a plain one, you know the screened device wins the pickup test almost every time.

We have run the C37 through side-by-side tests with fixed-draw pens using the same oil. The result is consistent: tasters could identify flavor notes on the C37 that disappeared on the fixed-draw device, because they could close the airflow down and concentrate the vapor. That is not marketing language – it is what happens when you give the user control over the draw. If your brand’s product story is about flavor quality, the C37 gives your customers the tool to actually experience it.

The airflow controller sits near the base of the device. Turning it open delivers a looser, cooler draw; closing it down produces a tighter, warmer hit with denser vapor. For a brand selling a full-spectrum oil, the ability to close the draw down helps the user taste the terpenes that get lost in airy hits. For a brand selling a smooth isolate product, the open setting gives the easy, gentle experience their customers expect. One device, two personalities – and the user decides, not the factory.

The C37 measures 24 x 16 x 102mm with a rounded bar profile. Six colorways are standard. The mouthpiece is plastic in custom colors, the tank is transparent for visible oil level, and the body takes custom coating plus UV. The button placement was tested for one-handed operation – thumb falls on it naturally – which sounds minor until you use a device where the button is a stretch.

Brands that compete on flavor quality. If your marketing says “taste the difference,” you need a device where the difference is actually adjustable. The C37 is also the right choice for a slightly higher price point – the screen, the airflow control and the bigger battery give retailers a reason to explain the price, and customers a reason to pay it.
