Upgraded vapor from a brand new hybrid heater
The PAX 4 upgrades the traditional conduction setup with a brand new hybrid heater, and it makes a distinction.
Immediately, vapor is stronger, cleaner, and extra composed. Taste comes via clearly and sticks round as an alternative of fading after a couple of pulls. Classes preserve that acquainted slow-burn rhythm, however with out the lingering, roasted edge that conduction vapes can typically depart behind.
At decrease temperatures, flavors are delicate and well-defined and cling on deep into the bowl. Step up the warmth, and it produces thick, seen clouds nearly instantly, with sufficient energy to deal with longer, regular attracts with out scaling down.
For these conversant in the lineup, the 4 lands squarely between the Mini and the Stream. It’s extra refined and longer-lasting than the Mini, whereas the Stream nonetheless pushes additional into heavier output. The 4 improves the normal PAX expertise with out altering its core formulation.
Traditional airflow: Sluggish and regular sips
Airflow follows the traditional slow-and-steady draw fashion PAX is thought for. It’s naturally tight and tuned for managed, relaxed sips fairly than aggressive pulls. Take lengthy, regular attracts, and it responds with constant, satisfying vapor that builds step by step all through the session. This isn’t a hard-and-fast ripper (take a look at the PAX Stream for that).
4 warmth modes
The PAX 4 rocks 4 distinct warmth modes from mild and flavorful to dense and heavy:
Petal 1 (Purple): 374°F/190°C
Petal 2 (Inexperienced): 392°F/200°C
Petal 3 (Yellow): 410°F/210°C
Petal 4 (Purple): 428°F/220°C

Sluggish to warmth up
Warmth up is on the longer facet. From a chilly begin, it took about 1 minute and 22 seconds to succeed in temperature, practically 90 seconds, with even slower instances because the battery drained. That makes it the slowest within the present PAX lineup. The PAX Mini heats up in round 20 seconds, the Stream in about 40 seconds, and most portables common near 30 seconds.
Giant oven, smarter design
The PAX 4 dry herb vaporizer holds as much as 0.3g of floor herb. Whereas the oven design is acquainted from earlier PAX fashions, the hybrid heater performs finest at that 0.3g mark fairly than the tightly packed half-gram hundreds some customers could also be used to. For a transportable, 0.3g remains to be a wholesome session measurement and greater than sufficient for many customers.

Additionally they redesigned the oven to make prepping and upkeep less complicated. The oven lid is less complicated to take away, and the highest of the oven now funnels into the chamber for simpler loading and fewer mess.

Standby mode is completely different
PAX’s standby mode is a nifty little function that helps protect your load throughout longer periods. After a set interval of inactivity (no movement), the petals will flip blue, the oven will begin to cool for a couple of minute, after which absolutely shut off. Decide it up, and it’ll relax into gear. On older fashions, this could often kick in after a few minutes of inactivity.
On the 4, standby initiates after about 30 seconds of inactivity and absolutely shuts off across the 60-second mark. That’s noticeably faster than units just like the Stream and the Mini, which don’t enter standby till round two minutes of inactivity.
In informal use, this feels a bit aggressive. Throughout group periods or longer solo use, the oven will begin cooling down fairly shortly after you set it down. It might assist with battery life, but it surely usually feels rushed.

Dry herbs solely
The PAX 4 is designed for dry herbs solely. It doesn’t work with dry concentrates, and PAX has no plans to supply a focus insert.
First rate battery life + USB-C
Battery life is respectable, however not a standout. On Temperature 3, I averaged round 45 minutes of runtime, or about 5 10-minute periods per cost. That is sufficient for a couple of stable periods, however heavier customers will seemingly discover themselves charging each day.
Charging speeds had been higher than anticipated. It hit about 25% in roughly 23 minutes, 50% in round 45 minutes, and absolutely charged in 70 minutes. PAX had instances of round 100 minutes. I examined this with each my very own USB-C cable and the included USB-C to USB-C cable and received the identical outcomes.

Traditional PAX Controls
Controls on the PAX 4 are so simple as regular, with the identical easy, single-button interface. Maintain to energy on. Click on as soon as to cycle via the 4 warmth settings. Give it a shake to substantiate your choice and to verify battery life.

Modern high quality and design
That is your traditional, fashionable PAX. The PAX 4 retains the signature design language that made the model fashionable within the first place. It doesn’t really feel fragile. The outer hardshell has a sturdy, stable really feel within the hand, with no flex or low-cost spots. All the pieces suits tightly and deliberately.
Very pocketable
The PAX 4 is simple to hold and constructed for all times on the go. It slips into nearly any pant pocket or small bag with out problem, and the light-weight aluminum physique by no means feels cumbersome.
It has a barely fuller really feel in hand in comparison with older PAX fashions, but it surely nonetheless stays slim, balanced, and discreet. Toss it in your pocket, preserve it in a small pouch, or carry it each day with out a second thought.

My complaints
There are many nice vaporizers you will get for lower than $250. I might see this touchdown comfortably at $200, however at $250, I’d hope for a bit extra.
And the standby mode bugs me a bit. It kicks in after about 30 seconds of inactivity and absolutely shuts off round 60. For me, that’s not sufficient time to get my bearings in between hits and bounce again in, and it defeats the aim of a session vape. The older PAX vapes have the right timing.
