Why you are getting a weak hit from your vape, and how to fix it

A weak hit almost always has one of seven causes: a worn coil, airflow set too open, power too low for the coil, an e-liquid that does not suit the device, a pod that is not seated properly, a low battery, or a flooded coil. Most of them take seconds to check and cost nothing to fix.

Start by pinning down what "weak" means for you, because the symptom points to the cause.

Match the symptom to the cause

What you notice	Most likely cause	Check first
Muted flavour, slightly burnt edge	Worn coil	Section 1
Thin, airy vapour, little throat hit	Airflow too open	Section 2
Cool, wispy vapour after a coil change	Power too low	Section 3
Satisfying flavour but it does not hit the spot	E-liquid strength or type	Section 4
Cuts in and out, inconsistent puffs	Pod seating or contacts	Section 5
Strong when charged, fades through the day	Battery	Section 6
Gurgling, spitting, liquid in your mouth	Flooding	Section 7

1. The coil is worn, or new and not primed

Coils are consumable. Residue from e-liquid, especially sweet flavours, slowly coats the wire and clogs the cotton, so the coil heats less evenly and the wick pulls less liquid. Flavour goes flat, vapour drops, and eventually you notice a burnt edge.

Fix: fit a fresh coil or pod. If the problem started with a brand-new coil, it may not have been primed. Drop a little e-liquid onto the exposed cotton, fill up and wait five to ten minutes before vaping. Our vape cotton guide explains why the wick needs to be fully soaked.

2. The airflow is too open, or blocked

Open airflow mixes more air into each puff, which makes the vapour cooler and thinner and softens the throat hit. If your kit has an airflow dial or slider, close it a step at a time until the draw feels fuller.

The opposite problem also feels weak. If the draw is tight and you get very little vapour, the air inlet may be blocked by lint or condensation. Clear it gently with a dry cotton bud. On draw-activated devices, moisture around the airflow can also make firing unreliable, so dry it off.

3. The power is too low for the coil

On a device with adjustable power, every coil has a recommended wattage range, usually printed on the coil, the pod or its box. Below that range the coil runs cool and the vapour is thin.

Fix: raise the power in small steps until the flavour comes through, staying inside the coil's range. This is easy to miss after a coil change, because a new coil may want a different setting from the old one. Some devices read the coil and set the power themselves; check your manual.

4. The e-liquid does not suit the device

This is the cause people overlook most often.

• Too thick for the coil. High VG liquids such as shortfills wick slowly through the small holes of a mouth-to-lung coil, giving weak, dry puffs. They are made for sub-ohm coils.
• Lower strength than you are used to. If you have stepped down in nicotine, the same kit will feel less satisfying. That can be part of the plan, so give yourself time to adjust before you change anything.
• A different type of nicotine. Nic salts feel smoother on the throat than freebase nicotine at the same strength. If you have switched from freebase to salts, a softer throat hit is normal.
• Cold weather. E-liquid thickens in the cold and wicks more slowly. Keep your kit in an inside pocket.
• Running low. If the liquid level drops below the coil's wicking holes, the wick starts to dry out. Top up before it runs that low.

Thinking about a stronger e-liquid? Move up one step at a time, and read how to pick the right nic salt strength without overdoing it first. It also helps to know the signs of too much nicotine. For a full guide to which liquids suit which kits, see can you use any e-liquid in any vape pen?

5. The pod is not seated properly

Pods connect to the device through small metal contacts, often held by magnets. If the pod is not fully home, or there is e-liquid or condensation on the contacts, the power reaching the coil can drop in and out.

Fix: take the pod out, wipe the contacts on both the pod and the device with a dry tissue, and push it back in until it clicks. If the device still flashes or will not recognise the pod, try a different pod. Pods wear out too.

6. The battery is low or tired

Many devices deliver less power as the battery runs down, especially compact pod kits. Charge it fully and try again.

If it hits well on a full charge but fades much sooner than it used to, the battery itself may be wearing out. Our guide to knowing when your vape battery needs replacing covers the signs. If it will not charge at all, start with what to check when your vape is not charging.

7. The coil is flooded

A flooded coil has more liquid than it can vaporise. You hear gurgling, feel spitting, and the vapour turns weak and wet. It happens after overfilling, hard or long draws, or big changes in temperature or air pressure.

1. Take the pod off

   Remove the pod or tank from the device.

2. Clear the excess

   Hold a folded tissue over the base and blow gently through the mouthpiece to push out the extra liquid.

3. Dry everything

   Wipe the pod's base, the airflow holes and the device's contacts.

4. Ease back in

   Refit the pod and take a few short, gentle puffs before vaping as normal.

To stop it happening again, fill only to the marked line, take smoother draws, and store your kit upright.

Still faint? It might be your taste

If everything checks out and the flavour still seems faint, the issue may be you rather than the kit. Vaping one flavour all day can dull how strongly you taste it. Switching to a contrasting flavour for a day or two often brings it back.

Quick checklist

Most weak hits end with a new coil. Make sure you pick the one made for your tank or pod.
