G Pen Hyer: Portable E-nail Dab Vaporizer

Grenco Science is forever evolving with their accelerated improvements on their devices. Although they are more known for their handheld devices like the G Pen Roam, Dash and the Micro+, we have seen their portable enail game increase in popularity. 

Grenco is giving the people what they want with this new release of the G Pen Hyer

This device is nothing like the G Pen Connect, the Hyer sports a portable enail housing that accommodates an extra large quartz chamber. The housing is connected to a controller by a cord that looks similar to an enail coil, but there is no xlr plug, instead they are connected together by powerful, heavy duty, magnets. 

A little overview on the controller, the G Pen Hyer controller stands about 3 and a half inches high and is a little over 1 inch in depth adding to this devices portability. There are 3 simple buttons to power the device on and off and to adjust heat and session settings based on user preference. There are 5 LED lights on the side that indicate each power setting, battery life, and alerts. Overall first impressions the controller looks sleek, showing off a matte black metal body with a geometric pattern on the top and bottom adding to its elegance. 

The cord connecting the portable enail housing to the controller appears to have a tough outer sheath, with those substantial magnets on either side. The portable enail housing is made up of an all metal body similar to the controller, once the tank and the adapter are removed the housing reveals a short open vapor path for effortless cleaning.

The adapter included with this kit is a 14mm male containing two rubber o-rings for a secure connection from your piece to the portable enail. The core of this device is its concentrate tank, its construction is truly impressive. The inner quartz chamber is massive, with the inner diameter and total dabbing surface measuring at 16mm wide. There is a tube located in the middle similarly to a titanium nail for a clear vapor path, that travels down to the bottom of the atomizer for easy cleaning. This Hyer quartz tank also features a stainless steel heating element that covers every inch of the bottom surface area for a fully even vaporized dab with minimal waste.

The "carb cap" that goes over the Hyer Quartz Tank is fully magnetic for easy loading and it contains two airflow holes at the top that can be capped off or left open for more or less airflow based on preference! The Hyer contains a 6000mAh monster sized battery that is charged through a aUSB-C charging port, this guy fully supports pass through charging so that the user can continue to dab without missing a beat.

Quick Tip: 

What is a Portable Enail?

A portable enail is a concentrate vaporization device that can be attached directly to a water pipe for added water filtration. Portable enails come in a variety of styles, up until recently portable enails did not have a digital display on them, had traditional conduction heating like a coil or a bucket and have now graduated to induction heating methods.

Advantages to Portable E-nails 

portable e-nail offers a more efficient, powerful, and smoother experience when combined with water filtration. Digital portable enails allow the user to customize their experience per their strength preference or concentrate’s vaporization point. There is a slight variation of vaporization points for each type of concentrate, utilizing a digital display will allow for accounting of this slight difference for the most controlled experience and cloud size control.
