Which devices work best with nic salts?

The short answer: a low-power, mouth-to-lung (MTL) pod kit with a higher resistance coil, roughly 0.8 ohms and above, is the best match for nic salts. That combination gives a tighter draw and a modest amount of vapour per puff, which is exactly what nic salts are made for. Big sub-ohm kits are the wrong tool, because they deliver far more nicotine per puff than a nic salt is designed for.

This guide explains why, what the numbers on a coil mean, and which kit types suit nic salts. If you are still choosing a strength, start with how to pick the right nic salt strength.

Why nic salts need a low-power kit

Nic salts are smoother than freebase nicotine at the same strength, which is why they are sold at up to 20mg/ml, the UK legal maximum. Strengths like that are meant to be taken in small puffs.

The more power a kit puts through its coil, the more liquid it turns into vapour with each puff. In a low-power pod kit, a 20mg/ml salt gives a measured, comfortable amount of nicotine. In a high-powered kit, the same liquid delivers far more, which is how people end up light-headed or feeling sick.

Most nic salts are also made with a thinner liquid, often around a 50/50 mix of PG and VG. That suits the small coils and wicks inside pod kits.

Mouth-to-lung or direct-to-lung?

MTL kits combine a tighter, more restricted airflow with low power, and that pairing is what makes them suit nic salts. Most pod kits are MTL by default, and many let you loosen or tighten the airflow to taste.

Coil resistance and wattage, explained simply

Coil resistance is measured in ohms. As a rule of thumb, the higher the resistance, the less power the coil needs and the less vapour it makes. You will usually find the resistance printed on the pod or coil, or listed in the kit's description.

Coil resistance	What it is like	Nic salt fit
1.0 ohm and above	Tight MTL draw, low power, cooler vapour	Ideal, especially for 20mg/ml
Around 0.8 to 1.0 ohm	MTL with slightly more warmth and vapour	Good for 10 or 20mg/ml
Around 0.6 to 0.8 ohm	Looser draw, noticeably more vapour	Better at 10mg/ml or lower
Well under 0.5 ohm	Open DTL draw, high power, big clouds	Not suitable for nic salts

Wattage follows resistance. MTL pod kits typically run at low power, somewhere around 10 to 20 watts, and some set the power automatically when you fit a pod. Sub-ohm kits often run at 40 watts or well beyond.

One point that confuses people: technically, "sub-ohm" means any coil under 1.0 ohm, so a 0.8 ohm pod is sub-ohm on paper. In everyday use, though, a "sub-ohm kit" means a bigger device with a very low resistance coil and an open draw. That is the type to avoid with nic salts.

The kit types that suit nic salts

Refillable pod kits

A refillable pod kit has a pod you fill yourself from a 10ml bottle. Depending on the kit, you either replace the whole pod when the coil wears out, or swap just the coil inside it.

They suit you if you want a free choice of flavour and strength, and lower running costs over time. Many come with more than one pod resistance, so you can pick the higher one for a 20mg/ml salt.

Prefilled pod kits

A prefilled pod kit is a rechargeable device that takes pods already filled with nic salt. There is no bottle, no refilling and no coil to change: when a pod runs out, you click in a new one.

They suit you if you want the simplest routine possible, or you are moving on from a single-use vape (banned from sale in the UK since 1 June 2025) and want something that feels similar. The trade-off is choice, as you are limited to the flavours and strengths that pod range comes in.

Larger pod kits and pod mods

Some bigger pod kits accept a range of coils, from MTL to DTL. They work with nic salts as long as you fit a higher resistance coil and keep the power low. They are worth a look if you want a bigger battery or more control, but check which coils the kit takes before you buy.

MTL tanks on a small mod

A mouth-to-lung tank on a compact mod gives the most control over airflow and coils. It is bulkier than a pod kit, so most people new to nic salts start with a pod, but tanks and mods are a good next step if you enjoy tinkering.

Why sub-ohm kits do not suit nic salts

Sub-ohm kits are built for big, dense clouds. They pair very low resistance coils with high power and open airflow, and they are designed for low-strength freebase, usually around 3mg or 6mg made up from a shortfill and a nicotine shot.

Put a nic salt in one and several things go wrong:

• Too much nicotine, too fast. Each puff carries far more nicotine than the liquid is designed for.
• A harsh hit. At high power, even a smooth salt can feel rough on the throat.
• Wasted liquid. A high-powered kit gets through e-liquid quickly, and nic salts are made to last in small puffs.
• Leaks and flooding. Thin nic salt liquid can seep through coils built for thicker, high-VG e-liquid.

If you enjoy big clouds, that is a different setup entirely: a low-strength freebase in a sub-ohm kit, not a nic salt.
