Fernway - 510 Stylus Battery

Fernway’s 510 Stylus Battery is built for both style and performance, pairing perfectly with any standard 510-thread cartridge. Featuring quick USB-C charging, a built-in power gauge, and passthrough charging so you can vape while it powers up, this pen-style device is all about convenience. Adjustable voltage settings let you customize your session—Green (2.6V) for max flavor, Blue (3.0V) for more vapor, Purple (3.4V) for balance, and Red (3.8V) for maximum cloud production. It even comes with a sleek cap that clicks into place, hiding your cartridge like a fine writing pen while protecting it from bumps and pocket lint. Simple controls make it easy: 5 clicks to power on/off, 3 to change temps, 2 for preheat, and 4 to check battery life. A discreet, pocket-ready essential for smooth draws whether you’re in Fort Greene, Brooklyn or waiting for the ferry in St. George, Staten Island. Available at our Staten Island store, or order online for pickup. You can also have it delivered via NugHubNY.com! In store, pick-up, or delivery... we got you!
