Should you get a PAX Era vaporizer or the G Pen Gio from Grenco Science? I used each of these vapes regularly over the summer, and if you’re wondering which one comes out on top, a better question you should be asking yourself is, “Which one is right for me?”

The difference between these proprietary, design-forward, same-priced (~$30) vapes feels charmingly aligned to the California cities from where each one hails. The PAX Era, born in San Francisco, is a high-tech, high-achiever, with a slick, featherweight, USB-shaped design, proprietary “pod” cartridges, and Bluetooth capabilities for temperature and session control. Solving pain points with technology? How very SF.

The G Pen “Gio,” by the good people at Grenco Science, was born in Los Angeles, has an ergonomic hourglass shape much appreciated by my thumb and forefinger grip, offers a satisfying heft in contrast to Era’s light battery, and produces a lush, showy vapor cloud. It’s got a curvy, sultry, flashy LA vibe.


What Are ‘Mids’ and Why Are They the Best Thing in California Cannabis?

In every state where they’re available, both PAX and Grenco Science work with quality producers to ensure you’re getting damn fine oil for their respective proprietary systems. Here in Washington state, I keep Heylo in my Era and Oleum Labs in the Gio. (Find a full list of partners in each state at the bottom of this article.)

The Era is built for customization and control. There’s a temperature slider on the app that goes from mid-400 degrees Fahrenheit to high-700s, giving you big terpene flavor at the low end, and a plush vapor cloud at higher temps. “Session control” lets you pick a hit size from microdose to large, and it dispenses that amount every time you puff until you either change the setting or remove the pod.

Benefits of the PAX Era:

  • It hits however you’d like
  • Dosing is easy, offering a safe, predictable session every time you use it
  • You don’t have to mess with your Era’s settings to use it (maybe you’ll never connect it to Bluetooth, and that’s okay)

Bottom Line: If control and specificity are important to you as a consumer, the Pax ERA is an unparalleled choice.

Grenco Science G Pen Gio

The Gio is a seamless, breath-activated experience—you just pick it up and puff. The optimal-temp science keeps terpenes intact so you get beautifully clear flavor notes, and a voluminous vapor cloud, every time. (I can confirm I hit the ever-loving shit out of my Gio and the cartridge seemingly never ran out.)

Benefits of the Gio:

  • The science behind it calibrates heating to optimal temp, with an advanced wicking system to regulate oil use
  • It offers a rich, velvety-smooth hit
  • Gio’s design makes the curves and weight feel good in your hand

Bottom Line: If you enjoy the heightened sensorial experience of a gorgeously smooth inhale and a plush vapor exhale, the Gio is a beautiful pick.

(Pro-tip: If there’s a sticker on your cart, consider peeling it off before you insert it into the Gio. I know that goes against the purpose of the label, but otherwise the cart can get sticky if the label is intact.)
