A Closer Look at the G Pen Hydout
If you're sneaking a sesh between errands or keeping things subtle at a show, the Hydout delivers smooth, satisfying hits without blowing your cover.
Stealth by Design
The Hydout doesn’t just talk the talk—it walks the walk when it comes to discretion. With its hidden magnetic mouthpiece cover, your cartridge stays protected from view and from light exposure, which helps maintain your oil’s quality. Slide it in your pocket or palm, and you’re instantly in stealth mode.

Customizable Hits
Every sesh is different, and your battery should adapt. The Hydout gives you full control with five adjustable voltage settings (2.4V–3.8V) and a 10-second preheat mode that’s perfect for unclogging cold or thick oils. From mellow to intense, your experience is fully in your hands.
Know Your Power
A crisp LED display shows your current voltage and remaining battery life—no guessing games, no surprise dead battery moments. It’s vaping made smarter.
Quick Charge, No Waiting
Out of juice? Plug in with USB-C fast charging and get back to your session quicker. (Pro tip: Bring your own cable—the Hydout doesn’t come with one.)

Benefits of a Discreet Vape Battery
A stealth-style 510 battery offers several key benefits—especially for people who want a discreet, portable, and low-maintenance vaping experience. Here are the top advantages:
Discreet Use in Public
A stealth-style battery is typically compact and minimalistic in design, allowing you to take quick hits without drawing attention. Whether you're at a concert, walking through the city, or on a break, it helps you fly under the radar.

Odor Control
The Hydout includes a magnetic mouthpiece cover that conceals the cartridge. This helps reduce residual smell, especially between hits, making it easier to store and carry around without attracting unwanted attention.
Protects Your Cartridge
The covered design isn’t just for looks—it shields your cartridge from light, dust, and damage, helping preserve oil quality and extending the lifespan of your carts. It’s especially helpful for those who carry their vape in pockets or bags.
Great for On-the-Go Sessions
Because they’re small and pocket-ready, stealth batteries are ideal for mobile lifestyles. Whether you’re traveling, hiking, or just don’t want to carry bulky gear, stealth vapes are made for convenience and portability.
Sleek, Modern Aesthetic
Minimalist designs look good and feel intuitive. Many stealth 510 batteries, like the G Pen Hydout, feature LED displays, matte finishes, or hidden mouthpieces that make the device look more like a tech gadget than a vape.
Your New Favorite Battery Has Arrived
Whether you're just diving into the world of cartridges or you're a seasoned sesher looking for an upgrade, the G Pen Hydout is built to keep your vaping routine discreet, powerful, and totally in control.
This is more than just a battery—it’s your go-to gadget for smarter, smoother, and stealthier sessions on the go.
