Get Lifted With the New G Pen Hyer

The G Pen Hyer is

“We are thrilled about the first launch of G Pen Hyer under the acquisition of Vapium,” says Chris Folkerts, CEO of Grenco Science. “Combining Hyer’s advanced engineering with Grenco Science’s design allows us to continue bringing best-in-class products to market — maintaining the integrity and foundation of both brands.”

The G Pen Hyer consequently represents the next step in e-nail technology. It builds on Hyer’s cutting-edge performance with the most advanced e-nail hybrid on the market. Smart heating technology delivers constant temperature output, resulting in a consistent and efficient experience with every session.

I reviewed this e-nail firsthand. Let me tell you — it has become my go-to for concentrates at home. The customization and ease are almost unmatched by competitors. Now let’s get into the specs. For a broader look at cannabis tech gadgets worth knowing about, see our

The G Pen Hyer comes with everything you need for a full concentrate setup.

G Pen Hyer: What’s in the Box

The G Pen Hyer pairs with virtually any glass rig you already own. The three core components are the battery, the tank, and the power cable. Here is everything included in the box:

• Battery
• Quartz Tank for Concentrates
• Concentrates Tank Cap
• Tank Housing
• 14mm Male Glass Adapter
• Power Cable
• USB-C Charging Cable
• Dab Tool
• Hemp Travel Case

That covers essentially everything you need for a complete dabbing setup. Additionally, a Dry Herb Tank Assembly is available for separate purchase.

Size and Usability

The G Pen Hyer is built for at-home use. The battery has some weight to it — but that weight is justified by what it delivers. The quartz tank is large. Consequently, it can feel heavy when inserted into a smaller rig. That said, the payoff is significant: you finally have room to load a proper dab without compromising.

Everyone dabs differently. Personally, I prefer one larger dab and enjoying it over a couple of hours. The G Pen Hyer accommodates that perfectly. It requires far less effort than loading multiple smaller dabs on other e-rigs.

The battery connects to the quartz tank via the power cable, which can feel slightly clunky compared to some setups. However, the tank size and battery capacity more than justify the form factor. Furthermore, this device operates simply: power on, heat up, power down. It beeps when your dab is ready — a small detail I genuinely appreciate. Five temperature settings and five time settings give you precise control over every session. It works equally well for small, quick dabs or longer, heavier hits.

The G Pen Hyer’s 6,000mAh battery lasts significantly longer than most competing e-nail devices.

Battery Life

The battery is large. It has weight. Nevertheless, it brings exceptional effectiveness to your concentrate experience. I typically have one to two dabs daily. After nearly two weeks of use, I still had approximately 40 percent battery life remaining — which is genuinely impressive for an e-nail.

Therefore, whether you are planning a long sesh or regular daily use, this device holds up well before needing a recharge. LED lights indicate battery life when the device powers off. Five lights represent the charge level, with each light equating to approximately 20 percent battery remaining.

Quality and Performance

This is a true quick-to-function device. To power on, hold down the power button. Press twice to heat up. Within 15 to 20 seconds, you are ready to dab. To power off, hold the power button down again. Additionally, the device features a magnetic cap with air filtration — ensuring consistent airflow with every session.

The G Pen Hyer consistently produces powerful, cloud-heavy hits. Potency and vapor quality remain intact regardless of the temperature setting you choose. You have complete control over both heat level and session duration, so the experience never feels overbearing.

Five temperature settings give you full control over every G Pen Hyer session.

For smaller dabs, set the device to a lower temperature and shorter time range. For larger dabs, increase both settings accordingly. Finding that balance matters. For example, loading a small dab on the hottest setting will likely burn your product. Consequently, awareness of what you want from each session is key — but customizing appropriately takes only seconds, and the results speak for themselves.

Customization

The G Pen Hyer features five temperature ranges and five time ranges. Two arrow buttons sit on either side of the power button. Use these to cycle through settings and find the color indicator that matches your desired range.

In terms of temperature, the G Pen Hyer heats to a range between 482°F/250°C and 842°F/450°C. Furthermore, the three-button operation paired with an LED interface offers fast activation via the 6,000mAh rechargeable lithium-ion battery. Pass-through charging over USB-C means you can use the device while it charges.

To customize the time range, hold both arrow buttons simultaneously. The lights blink white. From there, cycle through to select how many lights correspond to your desired session length. The interface is intuitive — notably more so than competing devices in this price range.

Consistent cleaning keeps the G Pen Hyer running at full performance.

Cleaning and Daily Maintenance

Easy cleaning is, in my view, one of the most important qualities of a great e-rig. The G Pen Hyer delivers here. After each dab, allow the tank approximately 30 seconds to cool — it gets hot. Then wipe it down with a cotton swab and isopropyl alcohol. That quick routine is all that is needed for daily maintenance.

For a deeper clean, unscrew the tank while it is completely cool. Then work through the components thoroughly with cotton swabs and isopropyl alcohol. This removes waxy buildup that accumulates with regular use. Additionally, if you use the G Pen Hyer semi-frequently or more, I recommend a full deep clean at least once a week. Clean the tank after every single use regardless.

With proper maintenance, you can use the G Pen Hyer as frequently as desired. It is strong, durable, and that quality is evident every time you pick it up.

G Pen Hyer: The Bottom Line

The G Pen Hyer delivers exactly what I want from an electronic rig: customization, durability, and ease of use. With other devices, I typically need two or three smaller dabs to reach the experience I am after. With the G Pen Hyer, however, I can enjoy the dab of my choosing and feel it for a sustained period afterward.

Temperature and time adjustments are simple. That flexibility is excellent for anyone who, like me, enjoys varying their session from day to day. The device does feel substantial — the tank is large, and on a smaller rig it can feel disproportionate. Therefore, investing in a larger glass rig to pair with it is worth considering. Beyond that, however, the G Pen Hyer thoroughly earns its size. The tank handles large dabs without compromise, and the battery life is among the best I have experienced.

Ultimately, the G Pen Hyer is the best at-home dab rig I have tried. It produces clouds like nothing else I have reviewed, and it does so consistently, session after session.
