REVIEW: Smyle Penjamin Car Key 510 Battery

The Smyle Penjamin Car Key 510 Battery is designed for those who prioritize discretion and portability when vaping on the go. Shaped like a realistic car key fob, this unique 510-thread battery allows users to carry and use their vape cartridges in public without drawing attention. Whether you value stealth or just want something you can keep on your keychain, the Penjamin Car Key makes it easy to stay discreet while out.

The Penjamin Car Key stands out as one of Smyle Lab’s most covert 510 batteries. Unlike other devices that still resemble vapes, this one mimics a car key fob so convincingly that even a close glance wouldn’t raise suspicion. It completely hides a full 1g cartridge within its body, with the mouthpiece tucked away from view. Once assembled, the cartridge remains securely enclosed, making it ideal for stealthy use in a variety of environments.

This device is equipped with a built-in rechargeable battery that keeps things simple. Charging is handled via a USB Type-C port, allowing for faster charging.

What really sets this apart from other batteries is its disguise. It features a small keyring clip so you can attach it right to your keys, making it nearly impossible to distinguish from a real fob. The outer shell has simulated lock, unlock, and trunk buttons like a real car key, with the center unlock button functioning as the power/firing button. It blends form and function into one seamless package.

Using the Penjamin Car Key is simple once your 510 threaded cartridge is connected. Click the main firing button to switch through three voltage levels, each identified by a different LED light: green for 2.7V, blue for 3.1V, and red for 3.6V. If your concentrate is particularly thick, a preheat mode is activated by double-clicking the button, warming your oil before hitting. This ensures smoother draws, especially in cooler temperatures or when using higher-viscosity concentrates.

To keep things stealthy, the Penjamin Car Key comes in color options like Black and Gold. The gold refers to the detailing on the fob-style buttons, giving it a touch of realism and subtle flair while still keeping it low-key.

The Smyle Penjamin Car Key 510 Battery is the perfect mix of discretion and functionality. If you’re looking for a battery that hides in plain sight, charges quickly, supports multiple voltage levels, and fits your lifestyle on the move, this one checks all the boxes. Whether clipped to your keys or stashed in a bag, it’s a smart choice for anyone who values privacy and performance in their 510 battery setup.
