If you are new to CBD vaping, the terms "pen" and "cart" often get used interchangeably—but they describe two different parts of the same setup. A cannabis pen (also called a vape pen) is the battery and mouthpiece device, while a cart (cartridge) is the pre-filled oil tank that screws onto it. Knowing the difference helps you buy the right pieces, avoid compatibility headaches, and get the most from your CBD.
Our top pick for most shoppers: a rechargeable 510-thread battery paired with separate, lab-tested CBD cartridges. This combo gives you the widest choice of oils, lets you replace only what runs out, and usually costs less over time than disposables.
Key Features
- Reusable 510-thread battery works with most standard CBD carts
- Button-draw or auto-draw activation for simple use
- Variable voltage to adjust vapor warmth and flavor
- USB-C or magnetic charging for quick top-ups
- Cartridges sold separately so you can swap strains or potencies
- Leak-resistant cartridge design with ceramic or cotton wick
- Lab-tested CBD oil with QR-coded batch results
Materials and specs matter. Batteries are typically made from aluminum or stainless steel with a lithium-ion cell, and they come in 510-thread or proprietary magnetic connections. Cartridges use glass or food-grade plastic tanks with a ceramic, quartz, or cotton wick; ceramic tends to handle thicker CBD oils better. Look for carts that are free of vitamin E acetate, MCT oil, and artificial cutting agents. A standard 510 cart holds about 0.5 mL to 1 mL of oil, and battery life ranges from 200 mAh to 650 mAh depending on size.

Can I use any cart with any pen?
Only if the pen has a 510 thread, which is the most common standard. Some disposable pens use proprietary magnetic connections, so always check the thread type before buying a cart.
Which is cheaper: a pen or a cart?
A reusable pen costs more up front, but replacement carts are usually less expensive than buying new disposable pens each time. Over a few months, the pen-plus-cart route typically saves money.
Are CBD carts legal to ship in the US?
Yes, hemp-derived CBD carts with less than 0.3% THC are legal under federal law, though some states have stricter rules. We ship only to states where CBD vaping products are permitted.
