Problem 1: My Vape Is Not Charging

Symptom: Plug in USB-C cable, nothing happens. No LED, no screen, no charging indicator.

5 fixes in order of likelihood:

1. Clean the USB-C port. Lint, pocket fluff, and dust build up inside the port and block the connection. Use a wooden toothpick (not metal — risk of shorting the contacts) to gently scrape out any debris. This solves about 40% of charging problems at Vape7Store.
2. Try a different cable. USB-C cables fail constantly. If you have a phone charger lying around, try that one. The cable that came with your vape (if one came at all) is often the cheapest part of the package.
3. Try a different power source. USB ports on computers, cheap plugs, and multi-port chargers sometimes do not deliver enough power. Plug directly into a wall socket with a known-good charger.
4. Let it warm up. If your vape has been in a cold room or car overnight, lithium batteries sometimes refuse to charge below about 5°C. Bring it to room temperature for 30 minutes then retry.
5. Check for physical damage. Drop tests, water damage, and bent USB-C ports can permanently kill charging. If the port looks damaged or bent, the device needs replacing.

If none of the above work after 10 minutes of troubleshooting, the internal battery has likely failed. For most pod kits this means device replacement. Browse Lost Mary BM6000 or Hayati Pro Ultra 25K as affordable replacements.

Problem 2: New Pod Tastes Burnt From the First Puff

Symptom: You just installed a brand new pod or coil. The very first puff tastes like burning cotton or chemicals.

Cause: The cotton wick inside the coil is dry. Firing a dry coil heats the cotton directly to over 210°C, which is where cotton begins to burn. The result is an acrid, harsh taste that will ruin the pod if you keep going.

The fix — prime properly:

1. Install the new pod but do not vape it yet.
2. Let it sit upright for at least 10 minutes. The cotton wick needs time to fully saturate with e-liquid from the pod reservoir.
3. For extra safety, take 3–5 short "dry puffs" (inhales without pressing the fire button, or without the battery connected if possible) to draw liquid into the wick.
4. After 10 minutes, take a gentle first puff. Short, soft, 2–3 seconds.
5. If it still tastes burnt, wait another 10 minutes and try again.

Most Lost Mary BM6000, Hayati Pro Ultra 25K, and RandM Tornado pods come factory-primed, but cold weather, rough shipping, or a pod that has been sitting upside-down can leave the wick partially dry. The 10-minute rest fixes this every time.

If a pod still tastes burnt after proper priming, the coil is faulty. Replace it. Browse replacement pods: Lost Mary BM6000 refill pods, Hayati Pro Ultra 25K pods, or RandM T32000 refill pods.

Problem 3: My Vape Is Leaking From the Bottom

Symptom: E-liquid seeping from the bottom of your device, leaving sticky residue on your hands, pocket, or desk.

7 causes and fixes:

1. Overfilled pod. If you recently refilled a refillable pod, you may have overfilled it past the maximum line. Tip any excess out and refill only to the fill line.
2. Cracked pod body. Dropped the device recently? Pods can crack invisibly. Inspect the pod carefully — any hairline crack means replacement.
3. Loose pod fit. The pod may not be fully clicked into the device. Remove it, wipe the contacts, and push it back in firmly until it clicks.
4. Stored on its side. Pods leak when stored sideways for long periods. Always store upright. If it has been on its side, stand it upright for 30 minutes before using.
5. Worn-out seal. Pods have rubber/silicone seals around the filling port that wear out over time. If the seal is degraded, the pod needs replacing.
6. Temperature change. Moving from a cold environment to a warm one causes air inside the pod to expand and push liquid out. Let the device stabilise at room temperature.
7. Chain-vaping. Too many puffs in too short a time floods the coil with liquid that cannot vaporise fast enough. Wait 15 seconds between puffs.

Emergency fix: If your vape is leaking now, wipe it with kitchen roll, tip it upside-down briefly over a sink so excess liquid drains, clean the battery contacts with a dry cotton bud, and reinstall the pod.

Problem 4: My Vape Is Crackling and Popping

Symptom: You hear crackling, popping, or fizzing sounds when you inhale.

Good news: This is usually completely normal. The sound is e-liquid being vaporised by the coil — like water hitting a hot frying pan. Sub-ohm and high-wattage devices crackle more loudly than MTL pod kits, but even Lost Mary BM6000 and Hayati Pro Ultra 25K devices crackle slightly.

When it is NOT normal:

• Excessive crackling with wet lips or tongue. This means the coil is flooded — there is too much liquid on the wick. Fix: take a few short dry puffs to clear the excess, and wait longer between puffs going forward.
• Crackling with a burnt taste. This means the wick is partially burned and the sound is coming from hot cotton, not e-liquid. Fix: replace the coil or pod.
• Loud popping with spits of hot liquid. This is a flooded coil combined with high airflow. Fix: clear the coil with dry puffs, reduce your draw intensity, and wait between hits.

Gentle crackling with clean flavour = normal. Loud crackling with burnt taste or liquid spitting = problem to fix.

Problem 5: No Vapour Coming Out

Symptom: You puff the vape, press the button if needed, and nothing comes out — no vapour, no taste, nothing.

Checks in order:

1. Is the battery charged? Check the battery indicator. If dead, charge it for 30 minutes before trying again.
2. Is the pod seated correctly? Remove and reinsert the pod. Make sure it clicks firmly into place.
3. Is the airflow blocked? Cover the airflow hole, then release — you should feel suction. If not, there is a blockage. Check the mouthpiece, airflow holes, and any valves for clogged liquid or debris.
4. Is it a draw-activated device? Some pod kits (like the BM6000) are draw-activated only — no button. Draw harder or longer. If nothing happens, check the draw sensor is not clogged with liquid.
5. Is the coil burnt? A completely burned coil produces almost no vapour and a faint acrid taste. Time for a new pod.
6. Is the pod actually full? On pod kits with clear windows, check the e-liquid level. An empty pod cannot produce vapour.

Problem 6: Weak Flavour or Weak Throat Hit

Symptom: You are getting vapour, but it tastes weak, bland, or lacks the nicotine hit you are used to.

5 likely causes:

1. Coil is dying. Pod coils wear out after roughly 6,000–10,000 puffs depending on design. Flavour fading is the first sign. Replace the pod.
2. Tongue fatigue (vaper's tongue). Chronic use of one flavour desensitises your taste buds. Switch flavours for 24–48 hours and come back — taste returns. Drink more water and try a palate cleanser like menthol or mint.
3. Wrong nicotine strength. If you recently switched from 20mg to 10mg nic salt, it will feel weaker. Check the strength on the pod.
4. Airflow too open. Looser airflow = more vapour but less flavour intensity. Tighten the airflow if your device has an adjustable ring.
5. Pod needs cleaning. Residue builds up on the mouthpiece and reduces flavour clarity. Wipe with a dry cloth weekly.

If you are losing flavour after a few days on every new pod, you may be chain-vaping too hard. Wait 15+ seconds between puffs to let the wick re-saturate.

Problem 7: Vape Auto-Fires in My Pocket

Symptom: You take the vape out of your pocket and it is warm, the screen shows it has been firing, and the battery has drained.

Causes and fixes:

• Stuck fire button: On devices with a physical button, pressure from keys or coins in the same pocket can hold the button down. Solution: carry the device in a separate pocket or use the lock feature (5 rapid clicks on most mod-style devices).
• Stuck draw sensor: On draw-activated devices (like Lost Mary BM6000), the sensor can get stuck if e-liquid has leaked into the device. Clean thoroughly with a dry cotton bud and leave upright overnight to dry.
• Faulty device: If the auto-firing continues after cleaning, the device has a hardware fault. Stop using it immediately — auto-firing drains the battery and can potentially damage the lithium cell, which is a fire risk. Replace the device.

Problem 8: Battery Not Lasting as Long as It Used To

Symptom: Your vape battery used to last all day and now dies by lunch.

Causes:

• Normal battery degradation. Lithium batteries lose 20–30% capacity over their lifespan (roughly 300–500 full charge cycles). After 12+ months of daily use, this is expected.
• You are vaping more. It creeps up gradually. Check if you are actually vaping more heavily than before.
• You switched modes. Did you enable Boost or Turbo mode? That cuts battery life by 30%+. Check your settings.
• Cold weather. Lithium batteries lose 20–40% effective capacity in cold environments. Keep the device close to body heat in winter.
• Background drain. If the device auto-fires (see Problem 7), it drains even when you are not using it.

Preservation tips: Avoid letting the battery drop below 10%, avoid leaving it on charge after 100%, store in a cool environment, avoid full discharge.

When to Give Up and Replace Your Device

Some problems are not worth fixing. Replace your device when:

• The device has been dropped in water and will not turn on after 48 hours of drying
• The USB-C port is physically damaged or bent
• The battery no longer holds any charge after a 2-hour charging cycle
• The device auto-fires repeatedly and cleaning does not fix it
• You see any battery bulging, swelling, or leaking — STOP using immediately and dispose of safely
• The device is more than 12–18 months old and you have already replaced the coil multiple times

Device replacement is cheap. The Lost Mary BM6000 is £6.99, Hayati Pro Max 6K is similar, and even flagship devices like the Lost Mary NERA 30K are £13.99. Do not waste time fighting a dying device.

Frequently Asked Questions

Why is my new vape not producing vapour?

The most likely cause is a dead battery, an unprimed coil, or a pod not seated correctly. Charge the battery fully, let the pod sit upright for 10 minutes to prime, and reinsert the pod until it clicks firmly into place.

How do you fix a vape that tastes burnt?

Stop vaping immediately, install a fresh pod or coil, let it sit upright for 10 minutes to fully prime the wick, take 3–5 gentle dry puffs, then start with short, soft draws. If the burnt taste persists with a properly primed new pod, the device itself may be faulty.

Is it normal for a vape to crackle and pop?

Yes, gentle crackling is completely normal — it is the sound of e-liquid being vaporised on the hot coil. Crackling only indicates a problem if it comes with a burnt taste or if hot liquid is spitting into your mouth.

Why is my vape leaking from the bottom?

The most common causes are overfilling, storing the device on its side, a cracked pod body, or chain-vaping causing flooding. Wipe the device, dry the battery contacts, reinstall the pod, and store upright.

How long do vape coils last?

Prefilled pod coils last 6,000–10,000 puffs depending on design, which equates to roughly 7–14 days of normal use for a typical vaper. Sweet, dessert, and cola flavours reduce coil life; menthol and fresh fruit extend it.

Can a burnt vape coil be fixed?

No. Once the cotton wick burns, the damage is permanent and continuing to use it produces harmful byproducts. Replace the pod or coil immediately.

Why does my vape battery die so fast?

Lithium batteries naturally lose 20–30% capacity after 12 months of daily use. Other causes include cold weather, using high-power modes (Boost/Turbo), auto-firing in your pocket, or simply vaping more than before.

Still Stuck? Here Is What to Do

If none of the fixes above solve your problem, the device is likely faulty. Do not persist with a malfunctioning vape — especially if you see any battery swelling, overheating, or unusual smells. Dispose of faulty lithium devices safely at a local recycling point (Tesco, Currys, and most council recycling centres accept batteries).
