Penjamin by Smyle Labs

Penjamin by Smyle Labs – 510 batteries that disguise themselves as familiar things

Penjamin by Smyle Labs is a line of portable 510 cart batteries, which the brand builds around the idea of “discreet” use: the device looks like an everyday item, but inside it has a full-fledged battery for 510 cartridges. On the official website , Smyle Labs directly emphasizes that they are the “Founders of the Penjamin” and sell 510-compatible solutions in various form factors.

The brand often presents its devices as a solution for “aromatherapy” and does not rely on complex menus or displays, but on a simple scenario: quickly take out, turn on, select the voltage and use without paying too much attention. This explains why Smyle Labs has so many models that disguise themselves as a pen, key, marker or other “unsuspecting” things.

Who is behind the Smyle Labs brand?

Smyle Labs operates as a commercial brand (Smyle, LLC) and promotes its “ Penjamin ” line as a separate identity. There is a trademark application in the public registers for “SMYLE LABS” (filed on December 12, 2023), which indicates the direction of online retail/wholesale of vaping accessories. This is an important marker that the brand is developing the category of devices and accessories as a business direction.

Penjamin Philosophy: Design that Hides Function

Discreet concept as the main “chip”

Most 510 batteries have a more or less standard design: cylinder, button, charging. Penjamin goes the other way: it makes the form factor so that it “dissolves” in everyday life. It’s not about beauty for beauty’s sake, but about the user’s behavioral scenario: minimum attention, maximum habit. That’s why the line includes options for “writing pen”, “car key”, “permanent marker”, etc.

Brand awareness without premium pathos

Smyle Labs doesn’t build communication in the style of “laboratory precision” or “audiophile” technology. They rely on viral, recognizable designs and simple functions that most 510 cartridge users really need: variable voltage, preheat, charging and normal draw. This is evident even from the description of the basic “ Penjamin Cart Pen ”.

Technological base: 510 format and voltage control

Compatible with 510 cartridges

The brand’s key base is the 510 thread. For example, the “Penjamin Cart Pen” is explicitly described as a cartridge battery and is compatible with 0.5g and 1g formats (cartridges not included).

Voltage regulation and preheat

For the “Penjamin Cart Pen,” Smyle Labs indicates the ability to adjust voltage and the presence of a preheat function. This is just the minimum control that allows you to adjust the behavior for thick liquids or different cartridges without turning the device into a complicated gadget.

Penjamin lines: what exactly does the brand do?

Penjamin Cart Pen: a pen that really writes

“ Penjamin Cart Pen ” is positioned as a “low-key writing pen and cartridge battery all-in-one”: on the outside it is an ordinary pen, but inside it is a battery for a 510 cartridge, with voltage regulation and preheat. This is one of the most understandable products in the line, because it combines disguise and simple everyday logic.

Car Key Penjamin: key format for maximum invisibility

A separate format is the “ Car Key Penjamin ”, which Smyle Labs describes as a “battery disguised as a car key” for discreet scenarios. It’s not about ergonomics “like classic batteries”, but about situations where the idea of camouflage is important.

Permanent Marker Penjamin: marker case with space for large cartridges

In the “Permanent Marker Cart Battery” Smyle Labs emphasizes the form factor of the marker and the fact that the case allows you to “hold and store up to 4g carts.” This is a story about compatibility with “thicker” cartridges and about protection/storage in the case.

Other form factors: Wandjamin, Robotjamin and more

The brand's main catalog shows that Smyle Labs regularly expands its line of unusual 510 batteries (Wandjamin, Robotjamin, Mini Plug, Purse, etc.). This confirms the strategic focus: different “shells” for one clear 510 scenario.

Who are Penjamin by Smyle Labs devices designed for?

Penjamin is aimed at 510 cartridge users who are not interested in technical depth of settings, but rather convenience and invisibility. This is a solution for those who already use 510 format cartridges and want to change the standard “stick-battery” to a more creative or discreet format.

The brand is well suited for:

• for users who value camouflage and minimal attention
• for those who want a simple battery without complicated menus
• for beginners looking for a straightforward 510 device
• for people for whom design is as important as function

At the same time, Penjamin is not aimed at users looking for advanced mods with displays, precise regulation down to tenths of a volt, or universal solutions for different material formats.

Scenarios for using different form factors

Pen format for everyday use

The Penjamin Cart Pen is perfect for those who want a more familiar look. It doesn’t look like a vape device and doesn’t attract attention in a bag or on a table. It’s a “pick it up and use” format, without explanations or unnecessary details.

Key format for maximum stealth

Car Key Penjamin is more focused on the discreet scenario. It is convenient to carry with the keys and is not visually associated with a vape device. It is the choice of those who value invisibility above the classic ergonomics of the battery.

Marker format for larger cartridges

The Penjamin Permanent Marker is suitable for users who use larger format cartridges or want a case that partially hides the cartridge itself. This form factor is more about capacity and protection.

Technical logic: what is important to know before buying

All Penjamin devices are 510 thread based. This means they are compatible with most standard 510 format cartridges . Before purchasing, it is important to consider:

• cartridge type and diameter
• need for preheat for thick liquids
• required voltage level

Most models have basic voltage regulation and a preheat function. This is enough for everyday use without deep technical intervention.

Build quality and real-world experience

Smyle Labs focuses on the external design and functionality of the case. The form factor may be non-standard, but inside the classic logic of a 510 battery remains: battery, control board, cartridge contact.

Autonomy depends on the specific model, but the format is designed for regular use without the need for daily charging. Charging is implemented through modern connectors in most new models.

Penjamin in today's 510 battery market

The 510 battery market is saturated with similar cylindrical models. Penjamin is different in its approach to design and positioning. It is not a technical “mod”, but a lifestyle product with basic functionality.

The brand doesn't compete with premium adjustable mods or display systems. Its strength lies in its recognizability and a format that easily integrates into everyday life.

That's why Penjamin often becomes an impulse purchase or an alternative to a classic battery for those who want something unconventional, but without the complexity.

Summary: When to Choose Penjamin by Smyle Labs

Penjamin by Smyle Labs is the choice when you need a 510 battery with easy handling and a unique look. This is a brand for users who value a combination of functionality and camouflage, without overpaying for complex technology.

If you need a clear device for a standard 510 cartridge in a form factor that doesn't look like a vape device, the Penjamin logically fits into this scenario.
