G Pen 510 Original Battery

The G Pen 510 Original is an ultra-compact, draw-activated 510 battery and, at just 24 x 21.1 x 56.7mm, the smallest battery G Pen has ever made. Inspired by G Pen's very first battery from 2012, it adds three voltage settings, a preheat mode and a digital display, all controlled with a single button.

Technical Specifications

Why Choose the G Pen 510 Original?

The 510 Original packs a display, preheat and adjustable voltage into G Pen's smallest-ever body, making it one of the most pocket-friendly batteries in our range, and draw activation keeps everyday use as simple as inhaling. Its lowest setting is 3.2V, the maximum our cartridge manufacturers recommend, so we'd suggest leaving it on that setting. If you'd like more settings within the recommended range, or a cover that hides the cartridge completely, the G Pen Hydout offers 2.4V, 2.8V and 3.2V options in a concealed design.

This device is sold strictly for use with prescribed medication only.

Caring for Your 510 Battery

These are general, basic care tips suitable for most 510 batteries. Your device manufacturer's own care instructions may differ, always refer to the instructions supplied with your device where the two don't match.

• Periodically unscrew the cartridge, even if you're not swapping it, cartridges can occasionally seize in the thread over time if left in place for long periods.
• Wipe the connection threads and centre pin with an IPA wipe every so often, oil residue and dust here can cause weak vapour production or a battery that won't fire properly.
• If your device has a preheat function, use it before each session, this helps the oil flow more smoothly and reduces strain on the battery and connection.
• Storing the device upright where possible helps prevent oil pooling into the mouthpiece, though there's no need to worry if this isn't always practical.
• Avoid extreme temperature and pressure changes (for example, a hot car or a flight), these can affect oil viscosity and lead to leaks.
• Don't overtighten the cartridge when attaching it, this can damage the seal and make it harder to remove later.
• Handle with care, avoid dropping or excessive shaking, which can disrupt internal seals.
