CCELL M4 Button-Less 510 Battery

The CCELL M4 is a slim, button-less 510 battery in a classic pen format, activated simply by inhaling. The successor to CCELL's popular M3, it adds USB-C charging and a stainless steel body while keeping the same low-profile design, making it a reliable, discreet choice whether you're new to cartridges or have used them for years.

Key Features

• Draw-activated: no buttons or settings, simply inhale to activate
• Fixed 3.6V output
• No preheat function, see the important usage note below before your first session
• Over-inhale protection cuts off after a maximum 10-second draw to prevent overheating
• LED indicator for battery status and activation feedback
• USB-C charging, compatible with any USB-C cable
• Durable stainless steel body
• Universal 510 thread, compatible with most 510-thread cartridges

Important: Please Read Before Use

This device runs at a fixed 3.6V. Our oil cartridge manufacturers recommend not exceeding 3.2V, and because the M4 has no preheat function, going straight into a full, multi-second draw on a fresh or recently changed cartridge can risk burning out the ceramic heating element, particularly with our premium oils, which are thicker and need a moment to soften.

Before your main draw, take 2-3 short "micro puffs" first. This gently warms the oil so it flows properly into the heating chamber, rather than sitting thick and cold against the element. This is especially important the first time you use a new cartridge, or after the device has been unused for a while.

Technical Specifications

Why Choose the CCELL M4?

The M4 is about as simple as a 510 battery gets: no buttons to press, no settings to choose and nothing to configure, which makes it a good first device or a dependable backup. Its slim stainless steel body is barely wider than the cartridge it holds, so it's easy to carry discreetly. The trade-off for that simplicity is a single fixed voltage with no preheat, which is why the micro-puff technique above matters. If you'd prefer the same slim pen with lower voltage settings and a preheat, the CCELL M4B Pro adds both, while the Yocan Kodo Pro is a compact alternative with fully adjustable voltage.

This device is sold strictly for use with prescribed medication only.

Caring for Your 510 Battery

These are general, basic care tips suitable for most 510 batteries. Your device manufacturer's own care instructions may differ, always refer to the instructions supplied with your device where the two don't match.

• Periodically unscrew the cartridge, even if you're not swapping it, cartridges can occasionally seize in the thread over time if left in place for long periods.
• Wipe the connection threads and centre pin with an IPA wipe every so often, oil residue and dust here can cause weak vapour production or a battery that won't fire properly.
• This device has no preheat function, take a few short "micro puffs" before your main draw to help the oil flow smoothly, see the important usage note above.
• Storing the device upright where possible helps prevent oil pooling into the mouthpiece, though there's no need to worry if this isn't always practical.
• Avoid extreme temperature and pressure changes (for example, a hot car or a flight), these can affect oil viscosity and lead to leaks.
• Don't overtighten the cartridge when attaching it, this can damage the seal and make it harder to remove later.
• Handle with care, avoid dropping or excessive shaking, which can disrupt internal seals.
