Free Bar Vape Nic Salt
This collection groups 261 products under the free bar vape nic salt listing, pairing refillable pod kits with the bar style 10ml nicotine salts that suit them. The devices run from budget pod systems under £5 up to 100W pod mods, so the practical question for most buyers is not which body looks best. It is which coil or pod the device takes, how long that coil lasts and how easily you can reorder it.
Coils are the consumable at the centre of every pod kit. The resistance stamped on the side decides the wattage, the draw style and which e-liquid the device will tolerate. Get that match right and a £5 kit will outperform an expensive one fed the wrong liquid. This page covers the resistances in this range, what mesh changes, how to prime a fresh coil and which pods carry across between devices.
Reading the number on the coil
Every coil carries a resistance in ohms. That single figure tells you almost everything about how the device will behave.
Coils above 1.0 ohm
These are mouth to lung coils. Resistances of 1.0 ohm, 1.2 ohm and occasionally 1.6 ohm run at roughly 8W to 15W, sip liquid slowly and give a tight cigarette style draw. They are the natural partner for a 20mg nic salt in a compact pod kit such as the Snowwolf Wocket or the Geek Vape Mero AIO.
Coils between 0.6 ohm and 1.0 ohm
The middle ground, often labelled restricted direct to lung. Around 15W to 25W, warmer and wetter than a true mouth to lung coil. Most pod kits ship with one coil from this band and one from the band above, which is why devices such as the Nevoks APX S2 and the Hellvape GRIMM cover two draw styles from one body.
Coils below 0.6 ohm
Sub ohm territory. A 0.4 ohm or 0.15 ohm coil wants 30W upwards, produces dense vapour and gets through liquid fast. Pod mods such as the SMOK Nord 50W, the Wotofo Manik and the Geek Vape Aegis Boost B100 will drive these properly. Feed them a low strength high VG shortfill rather than a 20mg salt, because at that vapour output 20mg is unpleasant.
Mesh against round wire
Round wire is the traditional build, a coiled length of kanthal wrapped around cotton. Mesh replaces it with a perforated strip, so the heated surface is larger and more even. Mesh ramps up faster, tastes cleaner from the first puff and spreads wear rather than burning through one hot spot.
Almost every coil sold for these kits is now mesh. Round wire still turns up in cheap mouth to lung coils where the slower ramp matters less. Given the choice at the same resistance, mesh is usually the better buy even though it drinks slightly more liquid.
Priming a new pod properly
Most burnt coils are killed in the first sixty seconds, not after two weeks. Dry cotton meeting a hot coil scorches instantly and no amount of soaking afterwards brings the flavour back.
Drip two or three drops of e-liquid into each visible wicking port until the cotton darkens. Fit the coil, fill the pod, then leave the device standing upright for five minutes. Take short gentle pulls at the lowest wattage for the first few draws, then build up to your normal setting. Refilling before the pod runs dry matters just as much, because exposed cotton scorches on the next hard pull.
How long a coil should last
One to two weeks is the realistic window for a pod coil in daily use. Sub ohm coils under heavy use can drop to five or six days simply because they process so much more liquid. The warning signs are consistent. Flavour flattens or turns faintly burnt, vapour thins out, the draw feels harsher and the pod may start to spit or leak as the cotton loses its seal.
Which e-liquids shorten coil life
Sweeteners are the main culprit. Sucralose caramelises on hot wire and leaves a dark crust that blocks flavour, so dessert, custard, candy and cola profiles are hardest on coils. Dark fruit blends with heavy sweetener sit close behind. Menthol and light citrus liquids are the kindest and will often double the working life of the same coil.
Viscosity is the other factor. High VG shortfills at 70/30 are too thick for the narrow wicking ports on a 1.0 ohm coil, so the cotton cannot keep up and you get dry hits. A 50/50 nic salt is the right fit there. Sub ohm coils below 0.6 ohm want the thicker liquid, because thin 50/50 floods the chamber and leaks out of the airflow.
Pod and coil cross compatibility
Coils are almost never universal. Manufacturers design a coil family then reuse it across several generations of device, which is where genuine compatibility comes from. SMOK has kept large parts of its RPM and Nord ranges on shared coil families, which is why the Nord 50W and the RPM Lite are easy devices to keep supplied. Geek Vape does the same across its pod kits, so the Aegis Boost B100 and the Mero AIO draw on Geek Vape coil families rather than anything generic.
The safe rule is to buy by coil name and not by kit name. Read the code printed on the old coil, order that code, then check the resistance matches what your device can drive. Two coils that physically fit are not interchangeable if one is 0.15 ohm and your device caps out at 25W.
Matching nic salt to the kit
Bar style nic salts are formulated for this class of device. They are blended around 50/50 PG to VG so they wick easily, salt nicotine stays smooth at 20mg and the flavours mirror the bar profiles most people arrived from. UK law caps nicotine e-liquid at 20mg per ml and nicotine bottles at 10ml.
For a coil above 1.0 ohm, 20mg suits a heavier previous smoker while 10mg suits a lighter one. In the 0.6 ohm to 1.0 ohm band drop to 10mg. Below 0.6 ohm move to a shortfill at 3mg or 6mg. The 2ml capacity limit applies to pods sold pre filled with nicotine liquid rather than to the empty refillable pods supplied with these kits.
Buying pod kits and coils in the UK
Vaping products are sold to adults aged 18 and over only, so every order is age checked before dispatch. Nicotine liquid must be notified to the Medicines and Healthcare products Regulatory Agency and meet the Tobacco and Related Products Regulations. Single use vapes have been banned from sale in the UK since 1 June 2025, so every device here is rechargeable with a replaceable coil or pod.
UK delivery is free on orders over £20. Adding a spare set of coils to a liquid order is the easiest way to avoid being caught without one. The team is on 07827 210361 between 8.30am and 4.00pm for compatibility checks.
Pod and coil questions answered
How do I know which coil my pod kit takes?
Read the code printed on the coil you are replacing rather than going by the name of the kit. Manufacturers reuse coil families across several devices, so the family name is what you order by. If the old coil is unreadable, the packaging or the manual will list it. The team can confirm a coil family on 07827 210361 between 8.30am and 4.00pm.
What does the ohm rating on a coil actually change?
Resistance sets the wattage the coil wants and therefore the feel of the vape. Coils above 1.0 ohm run at 8W to 15W and give a tight mouth to lung draw suited to 20mg nic salt. Coils between 0.6 ohm and 1.0 ohm sit at 15W to 25W with a looser draw. Below 0.6 ohm is sub ohm, needing 30W or more plus a low strength high VG liquid.
Is a mesh coil better than a round wire coil?
For most people yes. Mesh has a larger heated surface, so it reaches temperature faster, tastes cleaner from the first puff and wears evenly instead of burning out at one hot spot. Round wire still appears in some low cost mouth to lung coils where the slower ramp matters less. Mesh does draw slightly more liquid.
How should I prime a new coil?
Put two or three drops of e-liquid into each wicking port until the cotton darkens, fit the coil, fill the pod and leave the device upright for five minutes. Take a few short gentle draws at low wattage before moving to your normal setting. Skipping that wait is the most common reason a new coil tastes burnt on day one.
How often will I need to replace a pod coil?
One to two weeks is typical for daily use. Sub ohm coils can drop to five or six days because they process much more liquid. Change it when flavour flattens or turns faintly burnt, when vapour drops or when the pod starts spitting.
Which e-liquids ruin coils fastest?
Anything heavily sweetened. Dessert, custard, candy and cola profiles carry enough sucralose to caramelise on the coil and leave a dark crust that dulls flavour within days. Dark sweetened fruits are almost as hard. Menthol, light citrus and unsweetened tobacco blends are the gentlest and can double the working life of a coil.
Can I use a 20mg nic salt in any pod kit here?
Only in the higher resistance coils. A 20mg salt is designed for coils above 1.0 ohm running at low wattage, where vapour output is modest. Put the same liquid through a 0.4 ohm sub ohm coil at 40W and the nicotine delivery becomes harsh and unpleasant. For those coils use a shortfill at 3mg or 6mg instead.
Do coils from one brand fit another brand of kit?
Very rarely. Coil threading, height and airflow are designed around a specific pod, so cross brand fitment is the exception. What does carry across is a manufacturer reusing its own coil family over several generations of device. Buy by coil family name and check the resistance falls inside the wattage range your device supports.
