Choosing an e-liquid is, for many vapers, almost a religion. Some have been using the same flavour for years and defend it with the same conviction as their football team. And then there are those who open a new bottle every week as if it were their first day. The truth is that not all liquids work the same in all devices, and that is precisely the key that many people overlook when making their choice.
It's not just about flavours, but about understanding what you are asking of your device. Once you connect both variables, the experience changes completely. For those who want to delve deeper before buying, the Vapeototal guide to choosing an e-liquid is a good starting point: it explains in detail the PG/VG ratio, nicotine, and how they influence actual vaping.
Low-Power Devices: Pods and Compact E-Cigarettes
Pods and starter kits are the entry point for most. Small, discreet, and uncomplicated. This is where most mistakes are made with the liquid, because not everything works.
What to Look for in a Pod E-Liquid
These devices work with high-resistance coils, which means they do not generate the heat necessary to vaporise very dense liquids. Therefore, e-liquids with a high propylene glycol (PG) ratio are the most suitable: they flow better, saturate the coil faster, and provide a more pronounced throat hit, something that is especially appreciated by those coming from tobacco.
The most common ratios here are 50/50 or 60PG/40VG. The flavours that work best in these setups are usually menthol, light fruity, and tobacco flavours, as they maintain their intensity without losing definition with the type of vapour generated by a pod.
Nicotine salts are also prominent in this segment. Faster absorption, less throat irritation, and a sensation more akin to conventional tobacco. If the goal is to quit smoking or reduce consumption, this pod + salts combination is hard to beat.
Medium and High-Power Devices: Mods and Subohm
Here things change radically. A subohm mod operates at powers ranging from 40W to over 100W, and with coils below 1 ohm. Using a liquid with high PG in this type of equipment is a guaranteed way to ruin your throat and waste the flavour.
The Dominance of Vegetable Glycerin
In high-power devices, e-liquids with a high VG base are king. The most common ratios are 70VG/30PG or even 80VG/20VG. Vegetable glycerin produces denser and smoother vapour clouds, with a rounder and sweeter flavour. The downside is that it can dry out the mouth a bit at first, something that disappears quickly and can be solved by drinking water regularly.
The flavour profiles that perform best in these setups are creamy, dessert, and complex fruity flavours. A vanilla cream liquid with cookie, for example, reveals all its aromatic depth when vaporised at the right temperature. The same goes for tropical mango profiles, berries, or sweet tobacco blends: they need that heat and vapour density to express themselves well.
Longfill: The Option for Those Who Want to Control Everything
Longfills deserve a separate mention. They are large format bottles with concentrated aroma, to which the user adds the base and, if desired, nicotine. This is the option for those who have been in the vaping world for a while, know their palate, and prefer to customise every parameter. They also tend to be more economical by volume, which is not an insignificant detail if you vape daily.
Nicotine: How Much, When, and Why It Matters
The nicotine level is not just a matter of addiction, but also of compatibility with the device and vaping style.
For low-power devices, it is usually recommended to use between 10 and 20mg/ml, or directly nicotine salts that soften the hit without reducing the effect. For higher power devices, the amount drops considerably, usually below 6mg/ml, because the volume of vapour inhaled is much greater and nicotine is more than sufficient.
Using too much nicotine in a subohm mod is not only unnecessary: it can be quite unpleasant and ruin the flavour of the liquid. So less is more when upgrading your equipment.
Flavours That Work in Any Device
Although each setup has its preferences, there are flavour profiles that transition well between devices:
Menthol and fresh fruity flavours have a clear presence at any power. Menthol, in particular, is one of those flavours that never fails: clean, recognisable, and with a refreshing effect that many vapers consider essential, especially in summer.
Tobacco flavours, whether classic or with hints of caramel, honey, or wood, also work across a wide range of devices. Especially formats with nicotine salts in pods, or high VG versions for mods.
What does lose more with device changes are very complex and multi-layered profiles, such as certain creamy or elaborate desserts. These need the temperature and vapour volume of a subohm to show all they have.
Common Mistakes When Choosing E-Liquid
There is one that repeats more than any other: buying a high VG liquid for a pod. The result is a saturated coil, a burnt taste, and an experience that makes more than one return to tobacco thinking that vaping is not for them. When in reality, the problem was just the choice of liquid.
Another common mistake is not considering the compatibility between nicotine level and device. And, of course, blindly trusting the recommendations of others without considering your own equipment or personal tastes, which are always what matter most.
