What Wattage Should I Vape At? Vape Wattage Guide

You've bought a new vape, filled the tank or pod and switched it on. The screen says 5W, 20W, 60W or perhaps something considerably more alarming.

So, what wattage should you vape at?

The good news is that you normally don't need to calculate anything. Virtually every refillable vape pod and replacement coil is designed to operate within a particular wattage range specified by its manufacturer.

Your job is simply to find that range, start near the bottom and adjust the power until the vapour feels and tastes the way you like it.

Coil resistance can give you a rough idea of the wattage a vape is likely to use, but it isn't enough to determine the correct setting on its own. A modern mesh coil's construction, heating area, airflow and intended vaping style all affect how much power it needs.

What Does Wattage Mean on a Vape?

Wattage is a measure of electrical power. On a regulated vape, it describes how much power the device supplies to the coil when you take a puff.

The coil converts that electrical energy into heat. The heat causes the e-liquid held in the wick to form the aerosol that you inhale as vapour.

Increase the wattage and the coil generally becomes hotter more quickly and vaporises more e-liquid. Reduce it and the coil operates more gently.

That's why changing the wattage can make the same coil and e-liquid feel noticeably different without changing anything else.

What Does Wattage Do on a Vape?

Within a coil's intended operating range, increasing the wattage will generally affect several things at once.

Higher Wattage Usually Means Warmer Vapour

More power creates more heat at the coil, so the vapour usually becomes warmer as you increase the wattage.

Some people enjoy a warm, dense vape. Others prefer something cooler. There isn't one temperature that is automatically correct.

Higher Wattage Usually Produces More Vapour

A more powerful coil can vaporise more e-liquid during each puff.

That's why high-output DTL devices produce much larger clouds than small low-wattage MTL pods.

Wattage Can Change Flavour

Flavour often becomes fuller or more intense as you increase the power within the coil's recommended range.

There is a limit, though. More power doesn't continue improving flavour indefinitely. Push a coil beyond the point where its wick can keep up and the flavour can become harsh, overheated or burnt.

Different flavour notes can also become more or less noticeable at different temperatures, which is one reason two people using the same coil may prefer slightly different wattages.

Higher Wattage Uses More E-Liquid

If the coil vaporises more e-liquid with each puff, your tank empties faster.

This difference can be substantial when comparing a 10W MTL pod with a 60W DTL vape.

Higher Wattage Uses More Battery Power

More electrical power also means greater battery demand.

Running a variable-wattage device near the lower end of a coil's range will generally give you longer battery life than running the same setup near the upper end.

Where Do I Find the Correct Wattage for My Coil?

You normally won't have to look far.

The manufacturer's recommended wattage may be:

• Printed on the coil box
• Printed on the pod packaging
• Listed on the manufacturer's website
• Shown in the device manual
• Printed or etched directly onto a removable coil
• Printed on the pod itself with some integrated-coil cartridges

Vape Wattage Chart by Coil Resistance

Resistance and wattage are related, and lower-resistance coils are generally designed for greater power and vapour production. That makes resistance useful when you want a rough idea of the type of vape a coil may provide.

However, the relationship isn't exact enough to use resistance as a substitute for the manufacturer's specification.

The table below is therefore a starting-point guide only. The correct wattage for your particular coil may fall outside these broad ranges.

These ranges are deliberately broad. Coil resistance alone does not determine wattage. It's entirely possible for two coils with similar resistance to have substantially different recommended power ranges.

Why Can't You Calculate Vape Wattage from Resistance Alone?

You may have seen vape charts that use Ohm's law to suggest that a particular resistance automatically corresponds to a particular wattage.

That made more sense in the early days of vaping, when coils were relatively simple and devices offered fewer ways to control power.

Modern coils are much more varied.

Two 0.5-ohm coils could have different:

• Mesh or wire constructions
• Heating surface areas
• Amounts of wick
• Airflow requirements
• Liquid inlet sizes
• Intended vaping styles

All of those factors influence how much power the coil can use effectively.

Your regulated vape already handles the electrical calculations needed to supply the wattage you've selected. You don't need to calculate a voltage from the coil resistance before you can vape.

Should I Start at the Lowest Recommended Wattage?

That's usually the best approach, particularly with a new coil.

Suppose your coil is rated for 40–60W.

Start around 40W and take a few moderate puffs. If the vape feels too cool or the flavour is weaker than you'd like, move to 42W or 45W and try again.

Continue gradually until you find your preferred setting.

You may discover that 47W is perfect even though the coil can officially handle 60W.

There is no prize for reaching the top of the range.

Does Higher Wattage Give Better Flavour?

Sometimes — up to a point.

If the wattage is too low for the coil, the vapour may feel cool, thin and underwhelming. Increasing the power can bring out more flavour and warmth.

Eventually you'll reach a point where increasing the wattage no longer improves anything. The vapour may become excessively hot or individual flavour notes may start tasting harsher.

That's why the ideal wattage is often somewhere inside the manufacturer's recommended range rather than automatically at the maximum.

What Happens If Vape Wattage Is Too Low?

Using slightly less power than the recommended range usually isn't as immediately destructive as using too much, but the vape may not perform properly.

You may notice:

• Weak vapour production
• Cool vapour
• Muted flavour
• More condensation
• Gurgling or flooding with some tanks

The last problem can occur when the coil receives liquid faster than it is vaporising it.

If your vape tastes weak and sounds unusually wet or gurgly, check whether you're operating well below the recommended wattage.

What Happens If Vape Wattage Is Too High?

Too much power is the more serious mistake.

The coil can vaporise liquid faster than the wick can replenish it. The cotton then begins to dry out while the heating element remains extremely hot.

You may notice:

• Uncomfortably hot vapour
• Harsh flavour
• A dry or scorched taste
• Rapid darkening of the wick
• Shortened coil life
• A full burnt hit if the wick becomes scorched

Once the wick is genuinely burnt, turning the wattage back down normally won't fix it. You'll need a new coil or pod.

If that happens, you can browse Simply ELiquid's Replacement Coils to find the correct replacement for your device.

What Wattage Should I Vape at for MTL?

MTL devices generally operate at the lower end of the wattage scale.

Many current MTL coils and pods fall somewhere around 8–20W, although some warmer MTL and RDL-compatible coils use more.

The relatively low output produces a modest amount of vapour and works well with the tighter airflow associated with mouth-to-lung inhaling.

Again, use the recommendation for your pod rather than assuming that every MTL vape should run at 10W or 15W.

What Wattage Should I Vape at for RDL?

RDL covers a very wide middle ground.

A compact pod might provide restricted direct-to-lung vaping somewhere around 20–30W, while a more powerful pod mod may use considerably more.

Expect more airflow, warmer vapour and greater e-liquid consumption than with MTL.

What Wattage Should I Vape at for DTL?

DTL vaping generally uses the highest wattages because the coils are designed to vaporise more e-liquid while a large volume of air passes through them.

Modern DTL mesh coils commonly operate anywhere from roughly 40W to 80W, with some specialised coils designed for still more power.

Don't assume that a 200W vape mod needs to be used at 200W. A mod's maximum output tells you what the device can deliver. The coil tells you how much power you should actually use.

Does a Lower-Resistance Coil Always Need More Wattage?

Usually, but not always.

Lower-resistance coils are generally designed with greater vapour production in mind and tend to operate at higher power. That's why a 0.15-ohm DTL mesh coil is likely to need much more wattage than a 1.2-ohm MTL coil.

But resistance is only one characteristic of the coil.

A specially designed low-resistance mesh coil can sometimes operate efficiently at surprisingly modest wattage, while another coil with similar resistance may need significantly more power.

This is exactly why the recommended range printed by the manufacturer should always win over a generic resistance chart.

What Wattage Should I Use with Nic Salts?

Nicotine salts are normally used with low-powered MTL and RDL pod systems, particularly at strengths such as 10mg and 20mg/ml.

You don't choose a wattage because the e-liquid happens to be a nic salt, though. You still choose the wattage based on the coil.

The important point is to make sure the combination of coil output and nicotine strength makes sense.

A small pod producing modest vapour can work well with higher-strength nicotine. A powerful DTL coil producing a huge volume of vapour per puff generally requires much lower nicotine strength.

Does PG/VG Ratio Affect the Wattage I Should Use?

Not directly. Your coil determines the correct wattage range.

However, the type of coil also determines which e-liquid thickness it is designed to wick effectively.

Small low-wattage MTL pods often work best with 50/50 e-liquid, while higher-output DTL coils are usually designed for thicker high-VG liquids such as 70VG/30PG.

Our guide to VG vs PG explains how the ratio affects thickness, wicking and vapour production.

Do All Vapes Let You Adjust the Wattage?

No.

Many compact pod kits don't require you to choose the wattage at all.

Some provide a fixed output designed specifically for the installed pod. Others detect the resistance automatically and select an appropriate power setting.

More advanced pods may provide several power levels rather than allowing exact 1W adjustments.

Variable wattage becomes more common as you move towards pod mods and full vape mods.

If your device has no wattage controls, that's usually intentional. Use the correct compatible pod or coil and let the device handle the power.

What Is Smart Wattage?

Many modern vape kits can detect the resistance of an installed coil and automatically suggest or select a suitable wattage.

This can be extremely useful because it removes much of the guesswork for beginners.

Depending on the device, you may still be able to adjust the suggested setting within a safe range.

Smart wattage doesn't make the printed coil specification irrelevant, but it does make accidentally selecting a wildly inappropriate power level much less likely.

Does Increasing Wattage Burn Coils Faster?

It can.

A coil used near the upper end of its range experiences more heat and vaporises more e-liquid than the same coil used towards the lower end.

That doesn't mean using the upper part of the approved range is wrong. The coil was designed to operate there.

However, if maximum coil life matters more to you than maximum warmth or vapour production, using a comfortable setting towards the lower or middle part of the recommended range can be a sensible compromise.

Very sweet e-liquid can also shorten coil life regardless of wattage because residue gradually collects on the heating surface.

Why Does My Vape Taste Different When I Change the Wattage?

E-liquid recipes contain several flavour compounds, and they don't necessarily behave identically as vapour temperature changes.

At lower wattage, a flavour might seem lighter and cooler. Increase the power and you may notice more sweetness, warmth or intensity.

This is particularly noticeable with complex dessert, tobacco and fruit blends.

It's one of the main reasons adjustable wattage is useful: you're not merely choosing how big the cloud is. You're tuning the overall character of the vape.

How to Find Your Perfect Vape Wattage

If your device offers variable wattage, use this simple process:

1. Check the recommended range. Look at the coil, pod, packaging, manual or manufacturer's website.
2. Prime a new coil properly. Fill the tank or pod and allow enough time for the wick to become fully saturated.
3. Start near the bottom of the range.
4. Take a few normal puffs.
5. Increase by 1–2W.
6. Try it again.
7. Stop when the warmth, flavour and vapour feel right.

If the vape starts feeling too hot or harsh, you've gone past your personal sweet spot. Move back down.

That's all there is to it.

You don't need to solve an electrical engineering problem every time you replace a coil.

What If My Vape Automatically Changes the Wattage?

Some devices automatically adjust their power when you insert a different pod or coil.

That's normal.

For example, if you replace a higher-resistance MTL pod with a lower-resistance RDL pod, the device may recognise the new resistance and increase the wattage automatically.

This is a convenience feature designed to match the device's output to the installed hardware.

Do I Need a High-Wattage Vape?

Only if you actually want the type of vape that high wattage provides.

A 100W or 200W device isn't automatically better than a 20W pod.

If you prefer:

• A tight MTL draw
• Higher nicotine strengths
• Low e-liquid consumption
• Small, lightweight hardware

then a low-wattage pod may suit you perfectly.

If you prefer:

• DTL inhaling
• Large vapour clouds
• Low nicotine strengths
• Warmer vapour
• More airflow

then a higher-powered device makes more sense.

You can compare both types in our current range of Vape Kits.

Frequently Asked Questions

What wattage should I vape at?

Use the recommended wattage range specified by the manufacturer of your coil or pod. Start near the bottom of the range and gradually increase the power until you find the flavour, warmth and vapour production you prefer.

What does wattage mean on a vape?

Wattage measures the electrical power being supplied to the coil. Increasing wattage generally makes the coil heat more strongly, producing warmer vapour and vaporising more e-liquid per puff.

What does wattage do on a vape?

Wattage affects vapour temperature, cloud size, flavour intensity, e-liquid consumption and battery use. Higher wattage generally produces a warmer and larger puff, while lower wattage produces a cooler, gentler vape.

How do I know what wattage my coil needs?

Check the coil or pod packaging, the manufacturer's website or the device manual. Removable coils often have their recommended wattage range printed or etched directly onto the coil itself.

Should I vape at the highest recommended wattage?

No. The maximum is simply the upper end of the coil's intended range. Many vapers prefer a setting somewhere in the middle or lower part of the range.

Can I vape below the recommended wattage?

Going slightly below the range may simply produce weak, cool vapour, but operating far below the intended power can contribute to poor vaporisation, gurgling or flooding in some setups. Starting at the manufacturer's minimum is usually more reliable.

Can I vape above the recommended wattage?

It's best not to. Excessive power can overheat the coil and vaporise e-liquid faster than the wick can replenish it, leading to harsh flavour, dry hits or a permanently burnt wick.

Does lower resistance mean higher wattage?

Generally, lower-resistance coils are designed for more power and greater vapour production. However, resistance alone does not determine the correct wattage because coil construction varies significantly.

What wattage should I use for a 0.8-ohm coil?

Many modern 0.8-ohm coils operate somewhere around 12–20W, but check the exact recommendation for your coil. Different 0.8-ohm products can have different specifications.

What wattage should I use for a 0.6-ohm coil?

Many 0.6-ohm pod coils operate somewhere around 15–25W. Treat that only as a rough guide and use the range specified by the manufacturer.

What wattage should I use for a 0.4-ohm coil?

A 0.4-ohm coil may commonly operate somewhere around 20–35W, although some designs can differ substantially. The range printed on the actual pod or coil takes priority.

What wattage should I use for a 0.2-ohm coil?

Many 0.2-ohm DTL mesh coils are designed somewhere around the 40–60W area, although this varies by design. Always check the manufacturer's recommendation before setting the power.

What wattage is best for flavour?

There isn't one universal wattage for flavour. Start at the lower end of your coil's approved range and increase the power gradually. The setting where the flavour tastes best without becoming too hot or harsh is your personal sweet spot.

What wattage is best for big clouds?

Large clouds generally require a coil designed for higher wattage, generous airflow and high-VG e-liquid. Don't exceed your existing coil's wattage limit simply to produce more vapour.

What wattage should I use with 20mg nic salts?

20mg nic salts are usually paired with relatively low-output MTL pod systems. Use the wattage recommended for the installed pod or coil rather than choosing power based solely on nicotine strength.

Why does my vape automatically set the wattage?

Many modern regulated devices can recognise the resistance of the installed coil and automatically select or suggest an appropriate output. If the vape doesn't provide manual wattage adjustment, it has usually been designed to manage the power for you.

The Bottom Line

If you've been wondering what wattage to vape at, forget the complicated charts for a moment and look at the coil.

The manufacturer has already done most of the work for you.

Find the recommended range, start near the bottom and increase the wattage gradually until the vape feels right. Stay inside that range and let your preference decide whether you want the puff a little cooler, warmer, smaller or more powerful.

Resistance charts are useful for understanding why one coil is likely to operate at 12W while another uses 60W, but they should never override the specification for the actual coil in your device.

And if your vape doesn't have a wattage button at all, don't worry. Modern pods increasingly handle that part themselves.
