SMYLE LABS

Smyle Labs is a California vape hardware brand, especially popular for discreet, novelty 510-thread cart batteries that look like everyday objects. Its most famous design, for example, is the Penjamin pen.

Like other hardware makers, Smyle Labs sells rechargeable batteries and accessories rather than pre-filled oil. However, its designs stand out because they double as pens, car keys, lip balm tubes, markers and torches.

Each model also offers reliable basics, such as 3 heat levels, preheat, LED indicators and USB or USB-C charging. In addition, every battery fits standard 0.5 g and 1 g 510 carts. For the full lineup, also visit the official Smyle Labs site.

Most popular Smyle Labs products

The best-known items are the novelty 510 batteries, especially the viral Penjamin Cart Pen, a working ballpoint pen that hides a 510 cart.

Other popular models include the Car Key, Permanent Marker and Lip Balm Penjamins, as well as the Inhaler 510 battery. There is also the Pursejamin, a purse-style battery with cart storage, as well as limited drops like the Robotjamin and the Pixel and Pyro Torch designs.

How the Penjamin works with 510 carts

The Penjamin is a dual-function device, so the lower half is a real pen while the upper half holds a 510 battery.

1. To begin with, unscrew the bottom pen section and remove the top rubber cover.
2. Then screw in any standard 0.5 g or 1 g 510 cart.
3. After that, replace the rubber cover, which hides the cart until you push the mouthpiece out.
4. Finally, click the button under the clip 5 times to power on, twice for preheat and 3 times to change the heat level.

When you want to write again, simply reattach the bottom pen tip.

Price ranges for Smyle Labs devices

Smyle Labs generally prices its batteries as affordable novelty hardware. Core models like the Penjamin usually cost around $19–$35, while limited editions and special designs can cost a bit more.

Prices also vary by shop and promotion. Still, most standard batteries sit in the low-to-mid $20s.

Where you can buy Smyle Labs products

You can buy Smyle Labs batteries here and through authorized vape and accessory retailers, both online and in stores.

Because the devices contain no cannabis oil, most places treat them as adult-use vape hardware. However, legal purchase still depends on your local laws, as well as on the carts you plan to use with them.

Compatibility with 510 thread carts

Smyle Labs batteries use universal 510 threading, so they work with most standard 0.5 g and 1 g carts.

That said, very large or unusually shaped carts may not fit inside some novelty housings, such as the pen or key-fob bodies, even when the threads match.

What is the Penjamin cart pen?

The Penjamin is a discreet 510-thread battery that also works as a real writing pen. The cart screws into the body and stays hidden, while the top cap doubles as the mouthpiece.

Buttons under the clip also control power, preheat and voltage. In addition, it works with standard 0.5 g and 1 g carts.

How the Danksaber and novelty designs work

Novelty vapes like the lightsaber-style Danksaber also follow the same idea. A standard 510 cart hides inside an everyday object, such as a pen, key, inhaler or lip balm tube.

When you use one, you remove a cap or cover and insert the cart, sometimes with a magnet. Then you activate it with quick button clicks. As a result, these designs stay discreet and portable without losing compatibility.

Other discreet Smyle Labs batteries

Beyond the original Penjamin, the brand offers several other stealthy 510 batteries, including:

• Car Key Penjamin: shaped like a key fob, and it also uses a magnetic cart insert.
• Lip Balm Penjamin: looks like a lip balm tube, and it fires when you draw.
• Inhaler Cart Battery: resembles an inhaler, so it is especially discreet.
• Wandjamin and Pursejamin: a wand-style design as well as a compact purse-friendly one.

All of them support standard 510 carts, and they also include multi-click controls for power, preheat and voltage.

Do Smyle Labs batteries fit standard carts?

Yes. In fact, every Smyle Labs 510 battery fits standard 510-threaded carts in 0.5 g and 1 g sizes. Some models also include magnetic adapters for tool-free swaps, although the threading stays industry-standard.

Where to buy authentic Smyle Labs accessories

Authentic products sell through the official website and authorized retailers, including Mind Vapes, Vape Guy and select vape shops.

If you want to avoid counterfeits, check the seller first. Then look for branded packaging, USB-C charging and multi-click controls that match the official specs.

Penjamin Cart Pen vs. Lip Balm vs. Permanent Marker

The three most popular Penjamin styles differ especially in size, activation and cart fit:

Feature	Penjamin Cart Pen (classic)	Penjamin Lip Balm Edition	Penjamin Permanent Marker
Form factor	Real ballpoint pen; cart hidden under the top rubber cover	Lip balm tube; one tube is the battery, the other is a stash container	Marker body; cart stored inside the shell
Cart fit	0.5 g and 1 g 510 carts	Up to 1 g carts in storage; battery fits 0.5–1 g carts	Very large carts, up to 4 g+ with an extra-tall cap
Voltage	3 levels plus preheat	Variable voltage	Variable voltage plus preheat
Activation	Button (under the clip)	Draw-activated	Button
Charging	Rechargeable (Micro-USB on the classic)	USB-C fast charging	USB-C charging
Best for	Everyday carry that really writes	Maximum pocket stealth	Hiding very tall carts

In short, pick the classic pen for everyday use, the lip balm for pocket stealth and the marker for oversized carts.

Tracking Smyle Labs deals and limited drops

Smyle Labs often runs small-batch limited editions, such as the Heartjamin, the Robotjamin and special colorways. It also runs seasonal promotions through authorized retailers.

If you want the best deal, follow these tips:

• Firstly, watch the official “Limited Edition” and “Collections” pages for new drops.
• Sign up for email or SMS alerts, since that is where promo codes appear first.
• Compare prices at authorized shops, especially when they run bundles.

Because core models usually cost $19–$35, limited editions can cost more. However, sales on older colorways often bring prices back into the low $20s.
