Chugjamin 510 Battery 300mAh - Smyle Labs

The latest addition to the Smyle Labs "-jamin" family, the Chugjamin is a keychain-sized 510 battery shaped like a miniature beer mug—measuring just 2.75 inches tall and light enough to dangle from a keyring without weighing down a pocket. A cobalt-infused cell punches above its size class, delivering 9–12 full sessions per charge and recharging in under 30 minutes—faster than most full-sized batteries. Pass-through charging means the Chugjamin fires while plugged in, a critical feature for keychain-sized batteries that inevitably get forgotten on a dead charge. The gaming-culture branding resonates with the same young-adult demographic that made the Penjamin viral, extending Smyle Labs' social media momentum into yet another product line. For retailers, the Chugjamin occupies the same impulse-buy zone as checkout-counter candy—small, fun, and inexpensive enough to grab without deliberation.
