Resistance - Ohms/Ω

The main difference between a lower Ohm/Ω coil versus a higher number is that less voltage is required for the lower Ohm. The lower Ohm coil is generally likely to heat faster, produce a warmer vapour and more of it. Use our blog link for more information about what are Ohms and an easy-to-understand explanation about electrical resistance and the advantages and disadvantages of your various options.

Most coils have the Ohms Ω written on them.

If you're using regular coils you may see 1.2Ω, 1.5Ω or 1.8Ω for example.

If you're using a sub-Ohm coil you may see 0.15Ω, 0.3Ω, 0.5Ω, etc

How to prime coils

'Priming' is essential to avoid a vile burnt taste and ruined coils. For more information see our blog about priming coils.

A quick guide to regular e-liquid blends

65/70% PG - These blends also contain 30/35% VG and they're usually ideal for standard heating coils with a resistance of somewhere between 1.5Ω to 2.5Ω (this number is often written on the coil in small writing). They're often ok down to 1.0Ω but performance will depend on your coil. There is less vapour with PG liquids.

50% VG - these blends also contain 50% PG and they're designed for standard coils with a resistance of 1.0Ω through to 1.8Ω, as a guide. Many 50% VG blends also work well with sub-Ohm coils but it's trial an error and will depend on your coil. This juice blend will usually provide a medium amount of vapour but less flavour if you're not able to vary the power output on your device.

70% VG e-liquid - best suited to sub-Ohm coils (sub-Ohm means less than 1.0Ω) and a device with variable power because you will probably need to adjust the output to achieve optimum flavour. Higher VG blends produce a lot more vapour cloud.

Use our page link e-liquid blends if you want to know more about thicknesses, viscosity, PG / VG ratios, nicotine levels, vapour production and what makes for a smooth or harsh throat hit, and more or less flavour. This will also help guide you through to suitable e-liquid for your device and help tailor your preferences.

E-Liquid for sub-Ohm vaping

Sub-Ohm coils generally require thicker e-liquid, that means more of the VG than PG. It's the VG that produces more vapour and a smoother throat hit.

For sub-Ohm coils, the average is a 70-75% VG blend but it's trial an error, sometimes a 50% VG will work well for you, for others it's an 80% VG. It depends on your coils and your set-up and it depends on your personal preferences too.

Be aware that 6mg (0.6%) nicotine is often a maximum strength e-liquid to use in a sub-Ohm device. If you can’t take the hit from the increased vapour, turning the power down may cause more problems than it solves, instead you need to reduce the nicotine strength.

General help and guidance

We also have a lot more really useful information, advice and problem-solving articles relating to e-cig tanks, coils, and e-liquid, and more besides, on our blog.

Safety Notice

Sub-Ohm tanks and coils must be used by experienced and knowledgeable users as additional safety precautions must be practiced when using these items. These products need to work on a mod/battery capable of firing at sub-Ohm resistances. So, for example, if you have a 0.5 Ohm coil in your tank, your mod/battery must be capable of firing at 0.5 Ohm resistance, or lower. You also need to ensure your device can cope with the amps. Improper use can lead to physical injury and damaged equipment. For more information see our page about sub-Ohm basics.

Product Warranties

Use this internal link for our returns and refunds policy.

Electronic Cigarette Co (Healthy Start Ltd) offers the original buyer product warranties as set out below, which become effective from the date of purchase. During the warranty period, we will, at our discretion, repair or replace items that are defective.

These warranties give the purchaser specific limited rights, in addition to those rights under applicable local law. There are one or two exceptions, therefore, if an individual product page on our website stipulates a specific longer or shorter warranty period, that warranty takes precedent over those below.

Our warranties never provide cover for physical damage, misuse, or breakages.

Scratches and discoloration from regular use is considered normal wear and tear and is not covered by warranty.

Manufacturers are likely to require their serial number before providing a replacement item. This is due to the increasing amount of counterfeits in circulation. Please keep your packaging with the serial number, or take pictures of it before you discard it.

Batteries (eGo and 510 style)

Rechargeable e-cigarette batteries, both eGo and 510 style, come with a 28 day warranty and have a life expectancy of anything from 3 - 9 months, depending on usage and brand. The guarantee covers any manufacturing defects and any repairs, or replacements, if deemed to be faulty or beyond repair. The warranty doesn't provide for physical damage, misuse, or general wear and tear. Ensure you treat your battery well. Click here for our e-cig battery problems page for further information.

Chargers

USB chargers, wall chargers, USB car chargers and other battery chargers are covered by warranty for a period of 28 days. Physical damage, misuse, and general wear and tear are not covered.

Coils

These are consumable items lasting anything from a few days to a couple of months and there is no warranty applicable. Issues with coils are often caused by improper priming, letting the tank run low or drawing too frequently. Please click here for more information about how to prime e-cig coils correctly and it will guide you through to coils burning too. Coils are sold as a single-use disposable item and are covered by a DOA (dead on arrival) warranty only.

Drip Tips/Mouthpieces

These items are non returnable and are not covered by warranty but defective items will be refunded or replaced.

E-Liquid

Defective liquids will be replaced or refunded. This applies to e-liquid that is out of date or has a manufacturing defect.

Lithium-ion Batteries (18650 etc)

These consumable items are not covered by a warranty. Expect a typical lifetime of 300 charges when used properly.

Mods

Box style mods are covered for 90 days from date of purchase. The guarantee covers manufacturer defects and any repairs, or replacements, if deemed to be faulty or beyond repair. The warranty does not cover misuse, damage or general wear and tear. Any replacement provided does not increase the original warranty period.

Pod Kits

Pod style kits are covered for 90 days from date of purchase. The guarantee covers manufacturer defects and any repairs, or replacements, if deemed to be faulty or beyond repair. The warranty does not cover misuse, damage or general wear and tear. Any replacement provided does not increase the original warranty period.

Standard Kits

The kits comprise many parts and it's the individual parts that would be subject to their individual warranty cover, for example, an eGo or 510 style battery will usually be 30 days. Physical damage, misuse, or general wear and tear is not covered.

Tanks

The tank itself should last quite some time (usually many months). The heating element inside (the atomizer or coil head) will need to be replaced regularly (1 to 2 weeks on average). Both the tank and the coil heads are covered for faulty on arrival only (DOA). Take great care not to lose the seals on the tank or it will cause it to leak.

Please be aware that plastic/polycarbonate tanks are not recommended for use with abrasive e-liquids or particularly acidic e-liquids such as some fruit flavours. Some ingredients in e-liquid can cause cracking, frosting or even melting of plastic tanks. Abrasive and acidic flavours and flavourings include, but are not limited to, absinthe, cinnamon, spearmint, citrus fruit, cola etc. Please bear this in mind if you're using an e-cig with any type of plastic tank. Glass and metal tanks are impervious to these ingredients and are suitable for all e-liquids.

Rebuildable Atomizers & DIY Wire

There is no warranty applicable but manufacturing faults are covered.
