The PAX Flow is the newest flagship from PAX, the San Francisco brand that defined the pocket vaporizer. It brings the brand's first hybrid heating system and an airpath up to six times wider than earlier PAX models. It answers the one complaint PAX owners have voiced for years: the tight draw.

The Flow sits at the premium end of the market, and that price buys refinement over raw power. The battery covers about four to six sessions per charge, which the 40-minute full charge offsets well. For anyone who wants clean flavour and an easy pull from a vape that disappears into a jeans pocket, the Flow delivers.

The PAX Flow is a slim block of matte aluminium, 10.7 cm tall and about 3.5 cm wide. Despite the metal build, it weighs just 135 g, remarkably light for a premium portable. The soft-touch finish resists fingerprints and feels solid in the hand.

There is no screen. Four LED petals shine through tiny holes in the body to show heating status, mode and battery level, and a single button handles every control. You can even shake the vape at any time to check the battery.

The body does warm during longer sessions at the higher heat settings. A silicone cover, sold separately, improves grip and keeps your hand comfortable throughout.

The Flow is the first PAX with hybrid heating. A hybrid system works like cooking with both an oven and a pan at once: a conduction heater wraps around the oven while a convection coil sends hot air through the herbs from below.

PAX calls it the 3D oven because it heats the herbs from all sides. The result is even, thorough extraction with no dark spots or wasted material, and the herbs toast without ever burning.

Heat-up takes about 35 seconds on a full battery, roughly the time it takes to grind your herbs. Vapour arrives from the very first draw, even at the lowest setting.

Airflow is the reason this vape exists. The redesigned airpath moves 10 L of air per minute, which PAX rates at up to six times the draw strength of previous PAX models. The tight, restricted pull of older PAX vapes is gone.

The draw stays effortless even when you pull hard, and the vapour path is isolated from the electronics. This easy pull also makes the Flow a strong choice for anyone with limited lung power.

You can fine-tune the feel too. Partly covering the air inlet at the base with a finger tightens the draw to your taste.

The Flow runs from 180°C to 225°C across five presets. Four petal modes cover daily use: purple at 180°C for quiet, low-key sessions, green at 190°C for longer sessions that conserve herbs, yellow at 205°C for flavour, and orange at 215°C for the strongest extraction.

Lower settings preserve the lighter compounds and taste, while higher settings extract more in fewer draws. Starting at the green or yellow petal suits most people. The Flow uses presets only; there is no single-degree adjustment.

Behind the presets sits a patented real-time temperature control. A lip sensor and motion sensor detect when you draw and how hard, so the heat keeps pace whether you sip gently or pull deep. Set the vape down and it idles the heat, so the oven does not overcook between draws.

The fifth preset is unusual in the industry: a dedicated water pipe mode at 225°C. You unlock it by cycling through the four petal modes twice until the petals glow in multiple colours at once, and it then runs a continuous cycle of about five minutes.

At this heat the extraction is at its strongest, and water filtration cools and smooths each draw. Direct from the mouthpiece it is intense; through glass it becomes comfortable.

To use it as intended you need the water pipe adapter, sold separately, which fits 14 mm and 18 mm glass connections.

The stainless steel oven holds up to 0.3 g of ground herbs, one of the larger chambers in a pocket vaporizer. It also performs well with partial loads of around 0.2 g. The Flow works with dry herbs only.

Loading happens through a side-mounted door, a first for PAX. Press the circle on the door and the other side pops up; a built-in funnel guides the herbs in with less spillage. There is no need to flip the vape over.

The door holds itself shut with a secure magnetic seal and comes off completely for loading and cleaning. Keep it fitted when the vape travels in a bag. PAX recommends a medium grind, and the hybrid oven is forgiving about pack density.

You can make loading even tidier with the grinder and the puck press, both optional, which turn herbs into uniform pucks that drop straight into the oven.

Everything runs from one button and the four LED petals, so a session takes little effort.

1. Loading: Grind your herbs to a medium consistency. Press the circle on the oven door, fill through the funnel, tamp lightly with the included multi-tool and click the door back on.
2. Heating: Hold the button for two seconds. The petals glow pink while heating and turn green with a short vibration after about 35 seconds. Green means go.
3. Choosing a mode: Tap the button to cycle through the four petals, then wait three seconds or shake the vape to confirm.
4. Inhaling: Draw slowly and steadily. The real-time temperature control keeps the vapour consistent whether you sip or pull hard, and you can change modes mid-session at any time.
5. Finishing: The vape shuts off on its own when set down and left idle, or hold the button for two seconds. Let the oven cool for ten minutes, then empty the used herbs with the multi-tool.

The Flow carries a sealed 2000 mAh battery good for 35 to 40 minutes of continuous use, which works out to four to six typical sessions. Shake the vape before heading out and the petals show the charge level in 25% steps.

Charging is where the Flow shines. It is the first PAX herb vape with USB-C, and with a Power Delivery source it reaches a full charge in about 40 minutes, with 50% in around 20. It charges like a phone: any USB-C cable, anywhere.

Two usage facts worth knowing. The Flow does not run while plugged in; PAX designed it to charge between sessions to protect long-term battery health. The port also sits on the bottom, so the vape lies flat while charging.

The box includes a USB-C cable but no wall adapter, and a standard USB port stretches the charge to roughly 90 minutes. The fast charger unlocks the full 40-minute speed, and the optional charging dock keeps the Flow upright and topped up on a desk or bedside table.

The PAX app adds temperature profiles, haptic settings and session settings for anyone who likes to tune the details.

The Flow works fully without it. Power, modes, Bong Mode, battery check and LED brightness all live on the vape itself, so most owners will set the app up once and rarely open it again.

The entire vapour path sits under the oven door, visible and reachable, which makes the Flow among the easiest vaporizers to clean. PAX suggests a quick clean every three to five sessions.

The routine is short: let the oven cool, remove the door, clear the used herbs with the multi-tool and wipe the oven, door and airpath with a swab dipped in isopropyl alcohol. The door itself should never be submerged in liquid.

The oven screen pops out with the multi-tool and soaks clean in isopropyl alcohol in about 15 minutes. Three spare screens come in the box, and extra oven screens are available so you can swap a clean one in and soak the used one later.

The PAX Plus was PAX's previous flagship, a conduction-only portable with a loyal following. It costs less, its oven holds more at 0.5 g against the Flow's 0.3 g, and its battery lasts far longer per charge.

The Flow fixes the Plus's one real weakness with up to six times the draw strength, and adds hybrid heating, side loading and a dedicated Bong Mode. Charging moved to USB-C with a 40-minute full charge; the Plus still uses a proprietary charger.

The Plus suits slow sessions and long days away from a socket. Anyone who found earlier PAX draws too tight will feel the difference on the Flow's first pull.

The Venty is Storz & Bickel's flagship portable and the Flow's most direct premium rival. It brings an adjustable airflow dial, a smart flow meter and longer battery life.

The Flow weighs roughly half as much, 135 g against the Venty's 252 g, and its chamber is slightly larger at 0.3 g against 0.25 g. Its airflow is comparably open, and a full USB-C charge takes about 40 minutes.

Pocket carry and discretion favour the Flow; long back-to-back sessions favour the Venty.

The Mighty+ is Storz & Bickel's proven hybrid workhorse and a long-standing benchmark for portable vapour quality. It offers a dosing capsule system, longer battery life and years of proven reliability.

The Flow is far lighter and genuinely pocketable, a one-hand vape where the Mighty+ fills two. It charges fully in about 40 minutes over USB-C and adds a dedicated water pipe preset the Mighty+ lacks.

If most of your sessions happen at home and capsule convenience matters, the Mighty+ earns its size. The Flow is the one that actually leaves the house with you.

Right now we offer a 25% discount on all accessories when you buy any vaporizer here at MagicVaporizers. These are the add-ons we would pick for the Flow.

USB-C Fast Charger (45W): The Flow ships without a wall adapter, and its 40-minute charge needs a Power Delivery source. This charger unlocks the full speed.

Silicone Cover: Keeps your grip secure and your hand comfortable when the body warms at the higher heat modes, with every port and button still accessible.

Charging Dock: Charges the Flow standing upright on a desk or bedside table, since the port on the bottom otherwise leaves it lying flat. Note that it fits the bare vape, not one wearing the silicone cover.

Water Pipe Adapter: The companion Bong Mode was designed around; it connects the Flow to 14 mm and 18 mm glass for cool, water-filtered sessions.

PAX Grinder: Produces the medium grind PAX recommends for the hybrid oven, and grinders are 35% off when bought together with a vaporizer.

Puck Press: Presses ground herbs into uniform pucks for consistent packing and even heating, load after load.

Stash Tube: Carries around four to five sessions of herbs in an airtight, smell-proof tube with a tamper on the other end.

TightVac MiniVac: An airtight, smell-proof container that keeps ground herbs fresh between sessions.

Prep Tongs: Handle sticky screens and cleaning jobs without getting resin on your fingers.

Oven Screens (3-pack): Swap a clean screen in mid-week and soak the used one later; the screens are small and easy to lose, so spares are sensible.

Rounded Multi-Tool: Curved to fit the PAX oven for mid-session stirring, and it lifts the 3D screen out for cleaning.

Smell Proof Bag: Carries the vape, a grinder and your tools with the odour sealed inside.

MV StashBox + 8 Accessories: A lockable kit with a grinder, containers and tray that gives your whole setup one home.

Raised Mouthpieces (2-pack): The raised profile gives a more pronounced lip feel and slightly cooler draws; extras keep sharing hygienic.

Flat Mouthpieces (2-pack): The flush, snag-free option for pocket days and a low-profile look.

Replacement Door: The oven door is fully removable by design; a replacement covers you if it is ever lost or damaged.
