Best Coils for 100% VG E-Liquids
A guide to the best coils for 100% VG E-Liquids, including what materials to look for and how to keep your coils going for longer.
Compared to standard shortfills, 100% Vegetable Glycerin (VG) shortfill E-Liquids can seem like a whole different animal. Even experienced vapers may find themselves befuddled when it comes to vaping 100% VG vape juices.
What kind of device is best? What type of coil should you use? Will 100% VG E-Liquids ruin your coils?
Fear not: vaping Frugi’s 100% VG shortfill E-Liquids is easy as PG-free pie when you know what you’re doing. We’re here to help.
Read on for some advice on buying the best coils for 100% VG E-Liquids.
What device is best for vaping 100% VG?
This one’s pretty simple. Because of the composition of the E-Liquid and the viscosity of the juice, you should only be vaping 100% VG shortfill E-Liquids in a sub-ohm kit capable of firing at a higher wattage.
Using Frugi’s 100% VG shortfill E-Liquids in a pod kit or starter vape kit will lead to coil burning, leaking issues, and a generally unsatisfying vape experience, among other problems. It’s best to only use these shortfills in a compatible device, for the sake of your vape and the life of your coil.
The science-y reason behind this has to do with coil resistance, measured in ohms (Ω).
Sub-ohm devices use coils below one ohm (hence: sub-ohm), and the lower resistance means that they can conduct more energy from the battery. These devices are best suited to high VG E-Liquids, which tend to be thicker in viscosity, because the low-resistance coils allow for better saturation of the wick (the absorbent cotton or ceramic material inside the coil which absorbs the juices and feeds them to the coil).
If you’re unsure whether your vape device supports high VG E-Liquids, check the product information for your specific kit or read the user manual.
Will 100% VG E-Liquids ruin my vape coils?
If used correctly, no.
Contrary to popular belief, Vegetable Glycerin isn’t the main cause of coil death—it’s usually down to the sweeteners used in an E-Liquid, which will, over time, caramelise around the wiring inside the coil. Imagine sugar in a frying pan. Yikes.
This will cause the coil to produce less flavour and, eventually, it’ll start to taste burnt—at which point, you’ll need to replace it. If you find yourself having to change coils often, it could be because you’re vaping a heavily sweetened E-Liquid.

Wicking Holes
The main consideration when looking for the best coils for 100% VG E-Liquids is the size of the wicking holes.
If you take a look at your coil, you should see a few holes around the outside with exposed wicking material: these are the inlet ports where your coil absorbs the liquid from inside your tank or pod.
For 100% VG shortfills, because of the thickness of the juice, you’ll need to ensure that you’re using coils with large enough wicking holes. Otherwise, you risk your wicking material being undersaturated, which will inevitably result in a burnt hit—a fate which, unfortunately, can only be remedied by replacing the coil.
There is no definitive size of wicking hole that you should be looking for—instead, you may have to experiment to see which size wicking hole works best for you.
Below, we have an example: on the top, we have a pack of Smok Nord 1.4Ω coils, which are designed for MTL vaping and are therefore not suitable for 100% VG E-Liquids by default. These coils have very small wicking holes, which wouldn’t allow for full saturation of the wick with the viscosity of 100% VG E-Liquids.
Below these, we have a pack of Vaporesso GTi 0.2Ω sub-ohm coils, which have a large surface area of exposed wicking material, making them perfect for 100% VG juices. They also have a mesh build, which will mean more flavour and vapour production. These are a definite contender when it comes to the best coils for 100% VG E-Liquids!
Wicking Materials
In the same vein, you may want to consider the wicking material inside of your coil. Wicking material, as mentioned previously, is the absorbent substance inside your coil which sucks up the E-Liquid you put into your tank or pod so that the coil can turn it into vapour. Ta-da!
There are several different types of wicking material available, with cotton being the industry standard. Cotton is super absorbent, and it’s fairly universal as far as materials go, but if you’re looking to get more time out of your coil (and who isn’t?), you may want to consider a ceramic wicking material.
Ceramic is a highly porous material that’ll help keep your coil working for longer, reducing the risk of burning when properly saturated. You can find ceramic coils for many popular tanks and vape kits nowadays.
Conclusion
If you’re looking to start vaping Frugi’s 100% VG Shortfill E-Liquids, you’ve got a huge selection of compatible coils to choose from—but it’s up to you to find the right coil for your particular vape kit or tank.
When shopping for the best coils for 100% VG E-Liquids, we’ve established that you’ll need a sub-ohm coil. You’ll also want to bear two factors in mind above all else: wicking hole size and wicking material.
The rest is up to you!
