The Era, Pax’s ultra lightweight loose-leaf vaporizer that launched in fall of 2016, is now sporting some new features on top of its pocket-sized design, long-lasting battery, and smartphone app that lets you dial in the temperature. Pax Era owners can download a software update that enables Session Control, aimed at appealing to both veteran vape users and newcomers alike.

Using Session Control, you can tell the app how big a hit you want—micro, small, medium, or large. Once you’ve puffed that amount (even if takes a few draws), the Era shuts down for 30 seconds, giving you time to feel the effects of the vapor.

This lets new users limit themselves to small hits until they get used to how vaping feels. After all, without a harsh smoke hit to the back of the throat, it can be easy for a newbie to keep pulling on a vape pen, and accidentally overdo it. Experienced vapers can experiment with microdoses before working out or studying, or try capping leisure sessions with the medium or large setting to squeeze an extra day or two from the Pax pod.

The hit sizes aren’t time-based—meaning, it’s not three seconds for a small hit and five seconds for a medium one. Instead, sensors inside the Era determine how much energy you’re creating with each draw. If you pull harder, the progress bar in the app fills up faster, and even the temperature of the air entering the Era’s carb holes can affect how much energy gets to the pod. The hits are measured in microjoules.

This emphasis on precision and consistency also helps if you’re sampling different strains to compare their effects. Pax works closely with the companies making the pods, so they always look the same and hit the
