How to use the Cartisan Flex
What's in the Box
Your Flex comes with:
- Flex battery (always included)
- Flex Wax Atomizer (always included) — a ceramic orbital heating chamber optimized for concentrate vaporization
- Flex Flower Atomizer (included in the combo package) — a stainless steel chamber designed for flower
- USB-C charging cable
Both atomizers are also available separately as replacements.
Before You Start
Charge your device. Plug the Flex in using the included USB-C cable. The red LED stays on while charging, and a full
charge takes about 100 minutes. The device cannot be used while charging. Use a standard 5V/0.5A USB source — fast
chargers aren't supported and will trigger overvoltage protection.
Never submerge any part of the Flex — battery or atomizers — in alcohol or water. See the Cleaning section for the right
way to clean each part.
How the Flex Works
The Flex automatically detects which atomizer is attached and switches to the right mode. You don't change modes
manually — just screw on the atomizer you want to use:
- Flex Flower Atomizer attached → Voltage Mode (5 levels, for dry flower)
- Flex Wax Atomizer attached → Temperature Mode (3 levels, for concentrates)
- Standard 510 cartridge attached → Voltage Mode (5 levels, for oil cartridges)
When you attach an atomizer correctly, the device vibrates once to confirm the connection. If you don't feel a
vibration, the atomizer isn't seated properly — see Troubleshooting.
Button Basics
The Flex uses a single button:
- 5 clicks — power on or off (device vibrates, LED blinks 5 times)
- 1 click (while on) — cycle through the levels for the current mode
- Press and hold (Flower Atomizer or 510 cart) — fire while inhaling
- 2 clicks (Wax Atomizer) — start a temperature-controlled session
Note: if you've used other Cartisan variable-voltage devices, the Flex cycles differently. Most Cartisan 510 pen style
devices use 3 clicks to change voltage — the Flex uses 1.
Battery Level Indicator
Every time you power the Flex on or attach a new atomizer, the LED briefly shows your remaining battery:
- 🟢 Green — more than 75%
- 🔵 Blue — 35% to 75%
- 🔴 Red — less than 35%
This is separate from the mode-select colors. After the battery-level flash, the LED will display the color of your
current voltage or temperature setting.
When the battery drops below 3.2V, the red LED flashes 10 times as a low-battery warning. Recharge before your next
session.
Using the Flex with Flower
1. Attach the Flex Flower Atomizer. Screw it onto the battery — snug, but not overtightened. Wait for the confirmation
vibration.
2. Load the chamber. Add a small amount of flower. Don't overpack; airflow matters.
3. Power on. Click the button 5 times quickly.
4. Select your voltage. Click the button once to cycle through the five voltage levels:
- 🟡 Yellow — 2.2V
- 🟣 Purple — 2.8V
- 🟢 Green — 3.2V
- 🔵 Blue — 3.6V
- 🔴 Red — 4.0V
5. Start lower for milder pulls; move up for bigger hits. The Flex remembers your last setting.
6. Start your session. Press and hold the button while inhaling. The LED lights up while you're firing.
7. Session cutoff. If you hold the button for more than 15 seconds continuously, the device cuts off automatically (red
LED flashes 4 times) and enters standby to protect the battery. Release, wait a moment, and continue.
8. Power off. 5 clicks.
9. Let it cool before cleaning or switching atomizers.
Using the Flex with Concentrates
1. Attach the Flex Wax Atomizer. Screw it onto the battery — snug, but not overtightened. Wait for the confirmation
vibration.
2. Load the chamber. Add a small amount of concentrate. Don't overpack.
3. Power on. Click the button 5 times quickly.
4. Select your temperature. Click the button once to cycle through the three levels:
- 🟢 Green — Low (400°F)
- 🔵 Blue — Medium (500°F)
- 🔴 Red — High (600°F)
5. Start your session. Click the button twice quickly. The device vibrates once and begins heating — you'll see the LED
indicators flow clockwise around the ring as it heats up.
6. Inhale when ready. When the LED ring is fully lit and the device vibrates a second time (at 300°F), it's ready.
Inhale as the temperature gradually rises to your preset level. The indicators unwind counterclockwise during
vaping.
7. End the session. Sessions last up to 28 seconds and end automatically with a vibration and the LED fading out. To
end early, click the button twice.
8. Power off. 5 clicks.
9. Let it cool before cleaning or switching atomizers.
Using the Flex with Standard 510 Cartridges
The Flex battery works with any standard 510-thread cartridge.
1. Screw the cart on — snug, not overtightened.
2. Power on: 5 clicks.
3. Set voltage: 1 click cycles through the five levels above. Start on Yellow or Purple for thin distillate; move up
for thicker oils.
4. Press and hold the button while inhaling.
5. Power off: 5 clicks.
Switching Between Atomizers
Always power off first, let the atomizer cool, then unscrew and swap. The Flex will auto-detect the new atomizer and
enter the right mode when you next power on — no settings to change. Screw on snugly but not overtight. You'll feel a
single vibration when the atomizer is properly seated.
Cleaning Your Flex
Never submerge any part of the Flex in alcohol or water. This damages the electronics inside the atomizers, not just the
battery.
Flex Flower Atomizer:
1. Power off and detach.
2. Empty any residue from the chamber.
3. Wipe the interior with a dry cotton swab or small brush.
4. For stubborn residue, lightly dampen a cotton swab with 91%+ isopropyl alcohol and wipe only the interior surfaces.
Never soak, never pour alcohol inside.
5. Let the atomizer air dry completely — several hours to be safe — before reattaching.
Flex Wax Atomizer (ceramic orbital chamber):
1. Power off and let it cool.
2. Wipe out visible residue with a dry cotton swab.
3. To burn off stuck residue, reattach to the battery, set to Green (Low, 400°F), and fire briefly for 1–2 seconds —
similar to dry-burning a banger. Let it cool, then wipe again.
4. For heavy buildup, a cotton swab dampened with isopropyl alcohol is fine on the interior only. Never soak.
Battery:
- Wipe the 510 threads and center pin with a lightly dampened isopropyl alcohol swab.
- Keep moisture away from the button and USB-C port.
- Never wipe the body with a wet cloth.
LED Error Codes
If the Flex behaves unexpectedly, the LED tells you what's wrong:
White flashes 3 times: no atomizer is detected.
Check that the atomizer is seated, clean the 510 threads and center pin.
Red flashes 3 times: short circuit or overload protection.
Detach the atomizer, check for damage, clean threads, reattach
Red flashes 4 times (then standby): 15-second vaping timeout.
Release the button, wait, and continue
Red flashes 10 times: Low battery.
Recharge. You cannot use it while it's charging.
