🩺 Start here: the 60-second checklist
Before you assume the worst, run through the basics. A flat battery, the wrong charger or cable, or a clogged cooling unit can all look like a broken device, and none of them needs a repair. Work through this list in order:
Charge it for 30 minutes first
A fully drained Mighty won't switch on, and the Mighty+ manual's first answer to "cannot be switched on" is simply: charge the battery. Plug in the right charger (the Mighty+ charges over USB-C; the original Mighty uses its own round-plug power adapter), give it half an hour, then try again before troubleshooting anything else.
Check the cable and the charger
On a Mighty+, try the original USB-C cable and a wall charger of at least 5V/2A (a weak one shows "SLO" on the display). On the original Mighty, use its own power adapter; a USB charger won't fit it. Look inside the charging port for lint or debris.
Empty and inspect the chamber
Overpacked or old herb chokes airflow and hides symptoms. Empty the chamber, remove the cooling unit, and check the screens.
Read the display
On the Mighty+, look for an error code (ERR 001 to 005), "SLO" or "dct" on the display. Do the numbers change when you press + and -? These clues point you to the right section below.
🔋 Mighty not charging or battery dying fast
Battery complaints split into two very different problems: it won't charge at all, and it charges but drains quickly. Treat them separately.
It won't charge or won't turn on
- Swap the cable and charger. Use a cable that matches your port (USB-C on the Mighty+, the original round-plug adapter on the older Mighty). The Mighty+ manual recommends a USB charger of at least 5V/2A; for Supercharge it needs a USB-C PD charger of at least 9V/3A. Storz & Bickel recommends its own chargers and cables.
- Watch what happens when you plug in. On a Mighty+, the display should light up briefly, the device vibrates once, and the battery bars start flashing upward. "SLO" means the charger is too weak; ERR 003 means the charger or cable isn't suitable.
- Clean the charging port. Pocket lint packs into the socket and blocks contact. Gently clear it with a wooden toothpick or a puff of compressed air, never a metal pin.
- Check the temperature. ERR 001 or ERR 002 means the battery is too hot or too cold. Let it cool down, or bring it into a warm room. Storz & Bickel warns never to heat it with a stove, microwave or lighter.
It charges but the battery drains fast
The Mighty and Mighty+ run on two rechargeable lithium-ion cells. Storz & Bickel doesn't publish an official sessions-per-charge figure, and runtime depends a lot on your temperature. If a full charge that used to last you a day now gives you one or two sessions, the cells are aging. Storz & Bickel's manual treats battery wear as normal wear and tear, and the batteries can only be replaced by its service team.
| Symptom | Likely cause | Fix |
|---|---|---|
| Dead, no display at all | Flat battery or bad cable | Charge 30 min, swap cable |
| "SLO" on the display | Charger too weak | Use a stronger charger (at least 5V/2A) |
| ERR 003 | Unsuitable charger or cable | Use the original S&B cable and charger |
| Charges but 1 to 2 sessions only | Worn battery cells | Battery replacement by S&B service |
🔥 Mighty not heating or slow to warm up
Storz & Bickel puts the Mighty+ heat-up at about 60 to 70 seconds to 180°C (356°F), and the manual says it can take up to two minutes; the original Mighty is a little slower. If you get no heat, or it takes far longer than that, work through these in order:
Confirm it's actually charged
Storz & Bickel notes that heat-up time varies with the battery charge and the room temperature. Charge to full before blaming the heater.
Watch both temperatures
While heating, the Mighty+ display shows the actual temperature and the set temperature. The actual number should climb toward the set one, and a double vibration tells you it has arrived. If the actual temperature stalls well below the set one on a full battery, that points to a heater problem.
Check the room temperature
The Mighty+ is meant to be used between 5 and 35°C (41 to 95°F). In a freezing car or in direct summer sun it may heat slowly or show ERR 001 or ERR 002.
Try a reset
It restores the factory temperatures, which rules out a setting you changed by accident. See the reset steps below.
📳 Mighty not vibrating when ready
The Mighty+ gives a double vibration when it reaches your set temperature, and a single vibration when it switches on or off. If the vibration stops working, the device can still heat normally, so you can keep using it while you sort it out.
- Check the other signals. Does it vibrate when you switch it on or plug it in? If those buzzes work but the "ready" one doesn't, it may simply not be reaching temperature. Go back to the heating section.
- Watch the display instead. Even with no buzz, you can see when the actual temperature reaches the set temperature.
- Try a reset. It's free and takes 10 seconds.
- No vibration at all after a reset points to a hardware fault inside the housing. That's a job for Storz & Bickel's service center, not something to open the case for yourself.
💨 Weak vapor or a tight, restricted draw
If your Mighty heats but the vapor is thin or the draw feels tight, start with airflow before you suspect the electronics. Storz & Bickel's own troubleshooting for "no or too little vapor" starts with cleaning the cooling unit and the filling chamber.
(thin, wispy vapor)
(full, easy airflow)
(tight, restricted draw)
| What you notice | Most likely cause | Fix |
|---|---|---|
| Tight, hard-to-pull draw | Clogged screen or overpacked chamber | Clean screen, pack lighter |
| Thin, weak vapor | Herb too coarse or too little | Grind medium-fine, fill to the rim |
| Vapor fades mid-session | Cooling unit gunked up | Disassemble & clean cooling unit |
| Weak vapor even when clean | Leaking cooling unit | Do the finger test below |
Two causes are worth calling out. First, a clogged or worn screen: resin builds up in the mesh over time and strangles airflow. Storz & Bickel recommends brushing the screens after each use; a screen that's clogged, warped or torn should be swapped for a fresh one. Second, overpacking: the Mighty+ manual says an overfilled or tightly compressed chamber makes inhaling harder. Fill it to the rim, loosely.
If it's clean and still weak, try Storz & Bickel's leak check: remove the cooling unit, cover its air inlet with your finger, and inhale through the mouthpiece. If air still gets through, the cooling unit may be leaking (check the seal rings are seated) and may need replacing.

Shop parts & capsules →⚠️ Error codes and display messages
The Mighty+ does show error codes on its display. Here's what Storz & Bickel says they mean and what to do:
- ERR 001: battery temperature too high. Let the device cool down.
- ERR 002: battery temperature too low. Move it somewhere warmer, and don't heat it with a stove, microwave or lighter.
- ERR 003: the USB charger or USB-C cable isn't suitable. Use original Storz & Bickel accessories.
- ERR 004: the vaporizer is faulty. Switch it off immediately, unplug it, and contact the Storz & Bickel service center. Don't try to repair it yourself.
- ERR 005: someone blew into the device. Only inhale through it.
- "SLO": the charger is too weak. Use a more powerful one.
- "dct": not an error. It means a 15V/3A charger is connected and the device can run from the wall.
- Turns itself off: the Mighty+ switches off automatically 3 minutes after the last button press or draw, to save battery. That's normal. Weak draws may not be detected, so press a button now and then during a long, slow session to reset the timer.
🔄 How to reset the Mighty+
The Mighty+ manual describes a reset to default settings. It puts the base and booster temperatures back to factory settings (180°C base, +15°C booster). It won't erase anything you'll miss, and it's worth trying before you assume a hardware fault.
Take it off the charger
Unplug it so you're testing the device on its own.
Hold the power button for 10 seconds
Press and hold the orange ON/OFF button for 10 seconds.
Look for the confirmation
A vibration and a reset animation on the display confirm the reset. (Pressing + and - together is not a reset: on the Mighty+ it switches between Celsius and Fahrenheit.)
Power on and test
Turn it on, and watch for the heat-up and the double vibration at temperature. On the original Mighty, check its own manual, since the steps may differ.
🛠️ DIY vs service: what's actually safe to fix
Let's be honest about the line between a home fix and a repair job. The Mighty+ manual says repairs may only be carried out by Storz & Bickel's service center, that repairing it yourself invalidates the warranty, and that the batteries can only be replaced by their service team. Here's the realistic split:
| Problem | DIY? | What to do |
|---|---|---|
| Weak vapor / tight draw | Yes | Clean screens & cooling unit, replace screen, pack lighter |
| Won't charge | Yes | Right charger, swap cable, clean port, charge 30 min |
| ERR 001 / ERR 002 | Yes | Let it cool down or warm up |
| No heat after full charge + reset | No | Contact S&B service |
| No vibration after reset | No | Contact S&B service |
| Battery dies in 1 to 2 sessions | No | Battery replacement by S&B service |
| ERR 004, burning smell or damage | No | Stop use, unplug, contact S&B |
Cleaning, screen replacement, cable and charger swaps, and resets are all fair game. Anything involving the battery, heater, or vibration motor inside the housing is a service job. Storz & Bickel handles repairs through an RMA request on its website. If you bought your device from a shop rather than directly from Storz & Bickel, the manual says warranty claims go to that shop, so start there.
