| Works but flavor is weak | Wrong power/coolness setting | Fix #4 |
Fix #1 — Adjust Vape Not Hitting (No Vapor)
You take a draw and get nothing. No vapor, no flavor, just air. Here's the checklist:
1 Check the silicone stoppers. Every Adjust device ships with protective plugs in the mouthpiece and airflow slot. Peel them off — both of them. This catches roughly 40% of "dead on arrival" complaints.
2 Check your grip. The airflow slot sits on the bottom or side of the device. If your palm covers it while you hit, zero air gets in and the draw-activated sensor can't trigger. Shift your fingers and try again.
3 Tap it — gently. Air bubbles can get trapped around the wick inside the tank. A few light taps against your palm breaks the seal and lets liquid flow to the coil. Don't slam it on a table.
4 Draw lighter. All Adjust Vapes are draw-activated. A super hard suck actually creates too much vacuum and can lock the pressure sensor. Take a slow, steady 2-3 second draw instead.
5 Check e-liquid on the screen. If the display reads near-zero, the tank is empty. A 40,000-puff device running at max power (Rush Mode on MyRusher, Level 4 on MyCool) burns through liquid faster. That's the trade-off.
Adjust Vape Blinking but Not Producing Vapor
The device responds when you draw — lights blink — but no vapor comes out. The blink pattern tells you exactly what's wrong.
3 rapid red blinks = battery below 10%. Plug in a USB-C cable. Most Adjust devices need 60-90 minutes for a full charge (850 mAh on MyCool/MySour/MySweet, 1,000 mAh on MyRusher).
Steady blinking after a long draw = puff timer cutoff. Every Adjust Vape has a 10-second safety limit per puff. Release, wait 5 seconds, and draw again. If you need bigger clouds, switch to a higher power mode instead of pulling longer.
Alternating red-amber blinks = overheating protection kicked in. Set the device down for 2 full minutes. This happens most often when chain-vaping on Rush Mode (MyRusher) or max coolness Level 4 (MyCool).
Blinking persists after a full charge? Possible sensor malfunction or hardware defect. Contact Adjust Vape support.
Adjust Vape Not Charging
You plug it in. Nothing happens. No charging indicator, no screen response. Work through this:
1 Swap the cable. Cheap USB-C cables fail constantly. Try a different cable — ideally one you know works for phone charging.
2 Check the power source. Use a 5V / 1A adapter. Fast chargers (9V/2A+) can confuse the device's charging chip. A laptop USB port or basic wall brick works best.
3 Clean the charging port. Pocket lint is the silent killer. Use a dry toothpick or compressed air to clear debris from the USB-C port. Don't use anything metal — you'll short the contacts.
4 Wait 15 minutes. A completely dead battery sometimes needs a trickle charge before the screen kicks on. Plug it in and walk away.
| Model | Battery | Full Charge Time | Port |
|---|---|---|---|
| MyCool 40K | 850 mAh | ~60-75 min | USB-C |
| MyRusher 40K | 1,000 mAh | ~75-90 min | USB-C |
| MySour 40K | 850 mAh | ~60-75 min | USB-C |
| MyFlavor 40K | 850 mAh | ~60-75 min | USB-C |
| MySweet 40K | 850 mAh | ~60-75 min | USB-C |
Burnt Taste or Weak Flavor on Your Adjust Vape
The vapor is there, but it tastes like charred paper — or like nothing at all. This is a coil saturation issue 90% of the time.
1 Drop the power level. Higher power = more heat = faster liquid consumption. On MyRusher, switch from Rush to Normal mode. On MyCool/MySour/MySweet, drop to Level 1 or 2.
2 Let it rest. After every 3-4 puffs, wait 15-30 seconds. The wick needs time to re-absorb liquid from the tank. Chain-vaping is the #1 cause of burnt hits.
3 Check e-liquid level on screen. When the tank is below 20%, flavor degrades fast. The coil is partially exposed, and you're burning cotton instead of vaporizing liquid.
4 Warm it up. Cold temperatures thicken e-liquid. If your device sat in a cold car or winter pocket, hold it in your hands for 2-3 minutes before hitting. Don't use a hairdryer or microwave.
Adjust Vape Screen Not Turning On
Every Adjust device has a smart display showing battery percentage, e-liquid level, and your current mode. When that screen goes dark:
1 Charge first, diagnose later. A dead battery = dead screen. Plug in USB-C and wait 15 minutes minimum. Some deeply drained batteries won't show any indicator for the first 5-10 minutes of charging.
2 Force restart. Rare, but firmware can freeze. Press and hold the power/mode button for 10 seconds. On draw-activated models without a physical button, plug in the charger — the charging handshake can reset the chip.
3 Inspect for damage. If the screen has visible cracks, water spots, or distorted pixels, it's physical damage. The device may still work for vaping (try taking a draw), but the display is done. Contact Adjust Vape support if bought from the direct store.
Airflow Feels Blocked or Tight
You can barely pull any air through the mouthpiece. Feels like sucking through a coffee stirrer.
1 Locate the airflow slot. Bottom or side of the device, depending on model. Make sure nothing is covering it — stickers, your palm, a phone case.
2 Clean it. Use a dry cotton swab or toothpick to clear lint, dust, or condensation. Pocket carry builds up debris fast.
3 Adjust the airflow ring if your model has one. Turn it counter-clockwise for a looser draw.
Adjust Vape Leaking or Making Gurgling Sounds
Gurgling = condensation built up inside the airway. Not a defect — it happens with all disposables over time.
1 Hold the device upright and take 3-4 quick, light puffs without fully inhaling. This clears the condensation from the airway.
2 Wipe the mouthpiece and base with a dry cloth. Any visible liquid outside the device is condensation, not a tank leak.
3 Store upright, store cool. Leaving a device on its side or in a hot car (above 95°F) causes liquid expansion and seal pressure. Keep it vertical in a room-temperature spot.
Model-Specific Troubleshooting
All Adjust devices share the same 40,000-puff platform, but each model has a unique adjustment system that creates different trouble spots.
| Model | Unique Feature | Most Common Issue | Quick Fix |
|---|---|---|---|
| MyCool 40K | 4-level coolness | Max coolness drains battery 30% faster | Use Level 2 daily, Level 4 for short sessions |
| MyRusher 40K | Rush Mode (dual coil) | Rush Mode = shorter battery life per charge | Switch to Normal when battery drops below 30% |
| MySour 40K | 4-level sourness | High sour feels harsh on low liquid | Lower sour level when e-liquid is below 30% |
| MyFlavor 40K | Dual-flavor mix | One chamber empties faster than the other | Switch to single-flavor mode to use remaining juice |
| MySweet 40K | 4-level sweetness | High sweetness gunks the coil faster | Alternate between Level 2 and Level 4 |
When to Fix vs. When to Replace
Not every problem is worth troubleshooting. Here's the cut line.
If your device auto-fires (heats up and produces vapor without you drawing), stop using it right now. Disconnect it from any charger and place it on a non-flammable surface. Auto-firing can indicate a short circuit. Dispose of it properly — the EPA recommends taking lithium-ion battery devices to a certified e-waste collection point, not your regular trash.
Tried Everything and It's Still Dead?
Sometimes a device is just done. If you've run through all 7 fixes and nothing works, it's time for a fresh one. Every Adjust Vape ships from Texas with 40,000 puffs, USB-C charging, and a QR-verified authenticity guarantee.
Is My Adjust Vape Fake? Quick Authenticity Check
A counterfeit device won't perform like the real thing — and it's the most common reason a brand-new device "doesn't work."
| Check | Authentic Adjust Vape | Likely Counterfeit |
|---|---|---|
| QR Code | Scratch-off panel on box → scan links to verification page | No QR, or QR links to random site |
| Screen Display | Crisp screen with battery %, e-liquid level, mode indicator | Blurry screen, missing info, or no screen at all |
| Packaging | Clean print, correct brand colors, sealed shrink wrap | Typos, wrong colors, loose packaging |
| Adjustment Controls | Buttons/dials click firmly, mode changes reflect on screen | Mushy buttons, no mode response |
| Purchase Source | Bought from adjust-vape.com or authorized US retailer | Random marketplace, no return policy |
The FDA's Center for Tobacco Products regulates all Electronic Nicotine Delivery Systems (ENDS) sold in the US. Counterfeit devices bypass these regulatory requirements entirely. Buy from the Adjust Vape direct store to guarantee authenticity and warranty coverage.
Pro Tips — Keep Your Adjust Vape Running Longer
1. Store upright at room temperature. 60-80°F (15-27°C). Vertical storage prevents liquid from pooling in the airway.
2. Don't chain-vape. 2-3 second draws with 10-15 second breaks. Your coil will thank you.
3. Charge before 10%. Deep-discharging lithium batteries degrades their capacity faster. Plug in when the screen hits 15-20%.
4. Clean the USB-C port weekly. 5 seconds with a dry toothpick saves you from a "not charging" panic.
5. Mid-range settings for daily use. Level 2 coolness/sourness/sweetness + medium power = the sweet spot for flavor, battery life, and coil longevity. Save Level 4 and Rush Mode for sessions, not all-day vaping.
6. Keep it out of your back pocket. Sitting on your device bends the internal connections. Front pocket or bag.
Frequently Asked Questions
Why is my Adjust Vape blinking red?
Red blinks (usually 3 rapid flashes) mean the battery is below 10%. Plug in a USB-C cable and charge for 60-90 minutes. If it keeps blinking red after a full charge, the battery may be defective — contact support.
Can I fix an Adjust Vape that got wet?
Maybe. Immediately dry the exterior and charging port with a cloth. Stand it upright and let it air-dry for 24 hours. Do not charge it while wet. If the screen shows artifacts or the device behaves erratically after drying, replace it. Water and lithium batteries don't mix.
How long does an Adjust Vape take to fully charge?
60-75 minutes for MyCool, MySour, MyFlavor, and MySweet (850 mAh battery). 75-90 minutes for MyRusher (1,000 mAh battery). Use a standard 5V/1A USB adapter for best results.
Why does my Adjust Vape taste burnt on the very first puff?
Rare, but it happens if the device sat in a hot warehouse during shipping and the coil partially dried out. Take 3-4 short, gentle "primer puffs" (light draws without fully inhaling) to pull liquid into the coil. If the burnt taste continues after 10 puffs, you got a bad unit — request a replacement.
My screen shows 0% battery but I just charged it. What's wrong?
Try a different USB-C cable first — a faulty cable can show "charging" without actually delivering power. If the issue persists with a known-good cable on a 5V/1A adapter, the internal battery may be defective. This is rare but covered under warranty if purchased from adjust-vape.com.
Can I refill my Adjust Vape when the liquid runs out?
No. All Adjust Vapes are sealed, closed pod systems with pre-filled 20 mL tanks. They are not designed to be opened or refilled. Attempting to do so will void the device and can cause leaks or damage. When the e-liquid is depleted, it's time for a new device.
Does Adjust Vape warranty cover a non-working device?
Devices purchased directly from adjust-vape.com are covered. Reach out to customer support with your order number and a description of the issue. They'll typically offer a replacement for confirmed defective units. Devices purchased from third-party sellers may not be eligible.
Why does my MyCool produce less vapor on Level 4 coolness?
Level 4 coolness draws more power to activate the cooling system, which reduces the energy available for vapor production. This is by design — the trade-off for maximum ice is slightly thinner clouds. For the biggest clouds with some coolness, try Level 2 coolness on high power mode.
My Adjust Vape is auto-firing — what do I do?
Stop using it immediately. Unplug from any charger. Place it on a non-flammable surface away from your body. Auto-firing indicates a possible internal short circuit. Do not attempt to fix this. Contact Adjust Vape support and dispose of the device at a certified e-waste facility. The EPA provides guidance on proper lithium-ion battery disposal.
