PAX FLOW Vaporizer

The PAX Flow brings a new feel to the PAX lineup with long, comfortable draws and cloudy exhales. Where the PAX Mini gave us a compact, stripped-down version, the Flow sends us in the opposite direction with a larger build, a hybrid heater, and wide-open airflow.

It’s still easy to use with a single button, even smoother to draw from, and still slim enough to slip in and out of your pocket.

If you want a sleek, polished vape that handles long pulls with ease then the PAX Flow should be on your radar.

The PAX Flow is a solid pick for anyone who wants a hard-hitting vape in a sleek, pocket-friendly package. It looks good, hits well, and keeps things simple.

The Flow offers a stronger PAX experience, but it may not suit users who want maximum power or all-day battery life.

Review: Vapor Quality – Surprisingly strong with a soft touch

The PAX Flow surprised me. For years, I’ve associated PAX vaporizers with mellow, drawn-out sessions that you ease into. Short sips, and light puffs, but never big clouds. The Flow changes that with full, flavorful vapor at the low end and thicker, more satisfying exhales at the top.

Sessions on setting one or two always started strong. It didn’t need a long primer or heat soak. When it buzzed, it was ready. Each pull was smooth and flavorful, with visible vapor right away. Even longer draws were consistent. Vapor dropped off a bit near the end of the extended draws, but I expected that at the lower temps.

At settings three and four, the Flow kept up. It matched stronger inhales with milkier exhales, just as you’d hope, and did it with a subtle punch.

What really surprised me is how comfortable the vapor was throughout all of the session modes, especially the hotter ones. The clouds were thick enough to satisfy, but I never fell into a fit of coughs or got a scratchy throat. Those heavier hits produced comfortable vapor that went a long way. It could be a sweet balance of vapor and fresh air or a secret formula that PAX has conjured up. Whatever it is, it creates a pleasant experience.

The vapor just kept on coming, too. A 15-minute session with a full oven and a 50% charge gave me at least 20 solid draws before the battery died. It had more in the tank, but that was enough for me.

The Flow won’t knock your socks off, keep that in mind, but it’ll show up hit after hit.

Excellent airflow

The airflow on the Flow is excellent. It’s open and easy and competes with high-end models like the Mighty+. It’s not quite as wide as the Tinymight 2, but it’s noticeably more open than the POTV ONE and Lobo. It keeps up with strong pulls and never feels restricted unless you really push it.

Five heat modes to choose from

The PAX Flow comes with five curated Heat Modes. Instead of a single temperature, heat is adjusted on the fly to create a unique experience.

Stealth Mode (1 purple petal): For low-key sessions with minimal vapor. Great when you want to keep things discreet without sacrificing flavor. Does not dim the LEDs.

Efficiency Mode (2 green petals): Designed for longer, slower sessions. Starts light and gradually ramps up for a smooth, extended ride.

Flavor Mode (3 yellow petals): Prioritizes taste. This one delivers the most flavor-packed hits, especially in the first few draws.

Boost Mode (4 orange petals): For fast, heavy-hitting sessions with denser clouds.

Bubbler Mode (4 rainbow petals): Cranks the temperature up for the thickest clouds, made just for bubblers.

Heats up in 35 to 45 seconds

From cold, the PAX Flow hit its highest temp, Bubbler Mode (more on that below), in just 34 seconds on a full battery. Even with a low battery, it only stretched to about 40 or 45 seconds.

What really stood out was how quickly it responded to temperature changes. I could click from setting one to four, and it vibrated almost instantly. I took a hit right after, and the clouds came in denser and milkier without missing a beat.

Large 0.3g oven

In my first few sessions, I packed the PAX Flow with what I thought was enough and landed at around 0.2g. I filled the oven up to the top and then gave it a light tamp so that it was flush with the rim. It performed well with that.  When I pushed it to a full 0.3, the Flow kept right up. The pack was a little tight, but it worked just fine.

PAX Flow’s Bubbler Mode is promising

The PAX Flow comes with a fifth session mode, Bubbler Mode, which pairs with the PAX Water Pipe Adapter 2. It cranks the temperature up to 437°F/225°C for maximum clouds straight through a glass bubbler. This mode is a little hidden. You’ll need to cycle through all of the settings three times, and then the screen will light up with rainbow colors right after setting #4. This takes around 10 to 13 clicks total.

I haven’t gotten my hands on the water pipe adapter yet so I couldn’t test it out on a bubbler. I did give it a whirl without the adapter, and it left me pretty excited to run it through glass. I’ll update this section once I get a proper session in on a bubbler. For now, I’ll just say it looks promising.

Dry herbs only

The PAX Flow is designed for dry herbs only. It does not work with dry concentrates, and PAX has no plans to offer a concentrate insert.

Okay battery life

Battery life on the Flow is decent. It’s not great, but it’s not terrible either. I averaged about four full sessions per charge, with each session running around 10 minutes on temp setting 3. That came out to 35 to 40 minutes of runtime total.

In my tests, the first two sessions ran hot and strong with no issues. By session three, the battery started to dip, and the heat-up times started to slow. By session five, it died during heat-up. Lighter use might stretch it to five or six sessions.

There’s no replaceable battery, and while fast charging helps, it still means you’re hunting for an outlet once it’s low. It gets the job done, but don’t expect to run a marathon with it.

USB-C charge port (finally!!)

The Flow (finally) ditches the proprietary charge dock for quick USB-C charging. PAX says it’ll charge to 50% in 20 minutes and 100% in 40. In my tests, I hit 50% in 18 minutes, 75% in 27, and 100% in just under 37. No complaints here.

Sessions are easily controlled with a single button

The Flow vaporizer sticks with PAX’s single-button setup that works. Press and hold to turn it on, then tap to cycle through each session mode. That’s it.

It’s a little simpler compared to previous PAX vapes. For example, the PAX Plus powers on with one click, then you press and hold to enter temp mode, and tap to cycle through the settings.

It’s possible to accidentally turn the older PAX vapes on if you bump them just right. That’s much harder with the Flow.

Sleek and classy design

The Flow is an authentic PAX. It has a sleek outer shell, solid weight, and a clean, minimalist design. It comes in either black or green, both with a smooth matte finish that looks sharp and feels premium. The button has a nice click to it, and the whole thing feels balanced in the hand. It’s sturdy without feeling too heavy and classy without trying too hard.

The oven, placed right on the back of the device, is also new. Pop open the door, and you’ve got full access to the oven and vapor path. This area will get nice and sticky and collect a whole lot of debris as you’re loading it up, but it’s so easy to clean. It’s much better than the hard-to-reach path on the other PAX models.

A tad chunky but still slips in your pocket

The Flow dry herb vaporizer is the largest PAX so far, but it’s still very pocketable. It’s a bit taller and thicker than the PAX Plus. You’ll feel it in your pocket, no question, but it’s not too bulky or awkward. It’s solid for daily carry and slim enough to slide into a bag or jacket without a second thought.

Dimensions:

• Height: 4.2 in / 10.7 cm
• Width: 1.36 in / 3.45 cm
• Depth: 1.14 in / 2.9 cm

Here’s what I don’t like

Heat is my biggest issue. In Bubbler Mode, the Flow gets very hot within a few minutes. Even at temp 4, extended sessions got a bit uncomfortable, even around the mouthpiece. You’ll want the PAX Grip Sleeve, especially if you’re on a walk. It gets warm enough that you might want to put it down.

Battery life is just okay. You’re looking at four to five sessions, maybe six, before it needs a charge. No replaceable battery means once it’s dead, that’s it. Fast charging helps, but you’ll still need to find an outlet.

Then there’s the price. At $350, the Flow is in premium territory. At that level, I start looking at heavy hitters like the Tinymight 2. The Flow holds its own, but that price makes the competition harder to ignore.

Two-year warranty

The PAX Plus comes with a 2-year warranty on the device and the oven door (extendable to four when registered through PAX within the 30 days). You will need your device’s serial number to be eligible for warranty work, which can be located underneath the mouthpiece, along the side of the device. Please forward all requests to PAX. As with any vaporizer bought from us, you’re also covered by our 100% Satisfaction Guarantee.

For best results

The PAX Flow is versatile and will work with a variety of packs, settings, and draws. Here’s what I do for great results:

• Use a medium-coarse grind for the best results.
• Pack the oven full and tamp it down. A full 0.3g load is a tight fit, so fill it, tamp it down, and fill any gaps with more.
• Turn it on and set it to petal one or two for a lighter session, three or four for stronger vapor.
• Once it vibrates, sip it or rip it. It’ll keep up.

Pro Tip: Use the included multitool to push the herbs into the oven and tamp them down. It’s the perfect size.
