C38 CBD Vape Device | 280mAh | 1ml | LED Screen + Built-in Speaker | OEM & ODM

We get the same reaction from every brand we show the C38 to: a speaker? In a disposable CBD vape? Yes. And once they hold it, they understand. The C38 is a compact box device with a glass mouthpiece, a full screen, an airflow controller – and a built-in loudspeaker that plays a sound when the device powers on or when a session ends. It is the most distinctive hardware in our CBD lineup, and distinctiveness is exactly what a crowded market punishes you for lacking.

The speaker is not a novelty soundboard. It plays a short tone on power-on, giving the user audible confirmation the device is ready. In a market where most CBD users quietly wonder whether their device is on, an audible cue removes the guesswork. The sound can be customized to your brand – a logo chime, a soft tone in your brand’s key, even a spoken confirmation if you want to go that far. It is the kind of detail that gets mentioned in reviews, and reviews are where shelf products win.

Almost everything in this category uses a plastic mouthpiece. The C38 uses glass. The difference is immediate in the hand and on the lips – glass feels clean, dense and premium, and it never picks up the plastic taste that cheap mouthpieces add to the first puff. For a brand selling a premium oil, pairing it with a glass-mouthed device is the honest move: the packaging of the experience should match the price of the product inside.

The LED screen shows battery and puff count. The airflow controller lets the user tune the draw from tight and flavorful to open and cool. The 1ml tank holds a meaningful amount of oil for a box this size, and the transparent tank keeps the oil level visible. All the controls live under one button, so the feature set stays approachable despite the hardware underneath.

At 42 x 16 x 70mm, the C38 is a compact rounded box with five standard colorways. The body takes custom colors with UV finish, the mouthpiece is glass, and the bottom cap is plastic in custom colors. It looks like nothing else in the category, which is the point – on a shelf of identical pens, the box shape and the glass mouthpiece pull the eye.

Brands launching a hero product, or brands that sell through retail where shelf stand-out is the whole game. The C38 gives you a device your customers will talk about – the speaker and the glass mouthpiece are both conversation points, and conversation drives trial. It also fits gift-packaging programs: the box profile and premium feel support a higher price point without apology.

The speaker adds a small battery cost, which is why we pair it with a 280mAh cell and efficient coil options – runtime stays respectable. If you plan to sell in markets with strict advertising rules, keep in mind the sound is a device feature, not a marketing claim; we recommend checking local rules on audible features for vape hardware before finalizing the tone design.

We are an ODM/OEM factory in Dongguan, operating since 2013, ISO 9001/14001/45001 certified. Contact us to hear the speaker and test the airflow on a sample.

Before you lock in the tone design, we recommend testing the speaker in a retail-like environment. The volume is set to be clearly audible at arm’s length but not loud enough to be intrusive in a quiet space – we tuned it with that balance in mind, and we can adjust it for your channels. A music venue or festival environment might want a slightly louder confirmation tone; a wellness-focused boutique might want it softer. Both are easy for us to configure, which is the advantage of having the audio module tuned in-house rather than buying a fixed off-the-shelf speaker unit.

Hardware only – we manufacture devices, not e-liquids or cannabis oil. Buyers are responsible for compliance with local regulations for the filled product.
