Not all e-liquids are compatible with every refillable vape because compatibility depends on the design and functionality of the device. The VG/PG ratio, nicotine strength, and coil resistance are some of the things that have to be considered for a perfect performance and satisfying vape.
Compatibility relies much on the VG/PG ratio in e-liquids. High-VG e-liquids are those above 70% VG and are best suited for sub-ohm devices meant to produce large amounts of vapors. Most pod systems, however, or higher resistance coils do not work well with such thick liquids and instead require an e-liquid with a 50/50 VG/PG ratio or even greater PG content.
Using the wrong ratio may result in a number of problems including dry hits, lack of flavor, among others.
Another big concern is nicotine strength. Devices that are built for MTL vaping, like pod systems, really run most effectively with e-liquids of nicotine salts in the 20mg to 50mg strength range. For DTL, much lower strengths-pretty much between 3mg and 12mg-is required with freebase nicotine e-liquids, or else it could hit too hard on your throat. Vape Insights’ survey in 2023 stated that nicotine salts remain more popular at 62%, for they guarantee smoother experiences and speedier delivery.
Coil resistance and wattage also have an effect on e-liquid compatibility. Sub-ohm coils, being less than 1.0 ohm in resistance, run at higher wattages and are meant for thicker high-VG e-liquids. Higher resistance coils, common in more beginner-friendly refillable vapes, are better paired with thinner high-PG e-liquids to maintain coil longevity and flavor clarity.
Using the wrong e-liquid in a refillable vape will cause problems such as leakage, burnt coils, or reduced device performance. For instance, a pod system designed for 50/50 e-liquid will not cope well with the thicker viscosity of a 70/30 VG/PG blend; this would cause insufficient wicking and could lead to coil damage. Matching the e-liquid correctly to the device means optimal performance and hardware longevity.
As Elon Musk once said, “The first step is to establish that something is possible; then probability will occur.” That applies to vaping: choosing the right e-liquid for your refillable vape ensures not only the possibility but also the probability of an enhanced experience.
Most manufacturers will have recommendations for compatible e-liquids inside the device user guide. These are to be followed, so that your refillable vape performs and lasts long. For vapers desiring flexibility, picking the right combination of device and e-liquid means the experience will be personal and pleasurable.
