Cyrine Birdie 2G - 510 Thread Cartridge Battery

Designed specifically for larger 2 mL cartridges that standard bird-shaped batteries can't accommodate, the Cyrine Birdie 2G is a cute, bird-shaped 510 battery that matches the industry's ongoing shift toward bigger cart formats. Auto-draw activation means the Cyrine Birdie 2G fires with nothing more than an inhale—no buttons to press during use—while a 10-second preheat button warms thicker oils before the session begins. The compact, sleek design fits comfortably in a pocket or purse while still concealing a full-size 2 mL cartridge inside the body—a feat of compact engineering that competing novelty batteries haven't matched at this cart size. For retailers serving a female-skewing customer base, the Cyrine Birdie line outsells traditional pen batteries because it matches the aesthetic language their customers already carry—cute, colorful, and unapologetically playful. The 2G variant specifically addresses the growing "I bought a 2 gram cart and my battery doesn't fit" complaint that drives frustrated customers back to the store.
