G Pen Hydout 510 Battery - Neon Green Translucent

The Neon Green Translucent Hydout revives the iconic see-through tech aesthetic of the late 90s with a bold, modern twist. Compact, discreet, and built for everyday use, this Hydout features a magnetic two-piece shell that completely encloses your 510 cartridge, protecting it from drops and debris while keeping your setup clean and low-profile. Inside the sleek translucent body, the Hydout delivers full performance with variable voltage settings that allow you to dial in your preferred heat level, plus a 1.8V pre-heat mode that gently warms thicker oils for smoother pulls. This Retro edition also introduces two major upgrades: breath activation, letting you power up with a simple inhale, and USB-C pass-through charging, so you can continue using the device even while it charges.
