Finding the right e-liquid makes a huge difference to how your refillable vape performs. Whether you use a compact pod kit, a classic vape pen or a more advanced sub ohm device, each style of kit is designed to work best with a specific type of e-liquid. When the-liquid and device are matched correctly, flavour improves, pods and coils last longer and the overall vape feels smoother and more consistent.

This guide breaks down the most important things you need to know, including how e-liquid works, which blends suit each type of refillable vape, and which liquids are best if you previously used disposable vapes and want something familiar.

E-liquid is a simple mixture of propylene glycol (PG), vegetable glycerine (VG), flavourings and optional nicotine. When the coil heats the-liquid, it becomes vapour.

Understanding the PG/VG ratio helps you choose the right type for your device:

• PG brings a clear flavour and stronger throat hit
• VG produces thicker vapour but is heavier and slower to wick

Different refillable vapes are built with different coil sizes and power outputs, meaning they need the right viscosity of liquid to perform properly.

E-liquids might seem confusing at first, but they all fall into a few simple categories. Once you know what each type is designed for, picking the right option for your refillable vape becomes much easier.

Nicotine Salt E-liquids

Nic salts offer a smooth inhale and fast nicotine delivery. They’re particularly popular with pod users because they replicate the style of most disposable vapes, but with far more consistency and lower running costs. These-liquids work best at lower wattages.

50/50 E-liquids

Balanced e-liquids that work in almost any refillable pod kit or vape pen. They offer a light throat hit and clean flavour. Great for everyday vaping and for users who prefer a slightly sharper inhale than nic salts.

High VG E-liquids

High VG liquids are thicker and produce large, dense vapour. They’re designed for sub ohm tanks and powerful kits. Because they are thicker, they need larger coils and more airflow to wick properly.

Shortfills E-liquids

These are usually 50ml or 100ml bottles with space to add 1 or 2 nicotine shots. Ideal for sub ohm vapers and those who prefer long vaping sessions without regularly topping up small bottles.

Pod kits from OXVA, Vaporesso, Aspire and SMOK perform best with thinner liquids that wick quickly and avoid dry hits. For this reason, nic salts and 50/50 freebase-liquids remain the top recommendation.

Why these-liquids work so well:

• Pod coils are compact and heat quickly, so they need fast wicking
• Nic salts stay smooth even at higher nicotine strengths
• 50/50 liquids offer strong flavour without overwhelming the coil

If you want reliability, smooth flavour and minimal fuss, these blends give the best results across all pod systems.

Vape pens sit between pod kits and sub ohm devices in power, so they need something that delivers flavour clearly but doesn’t overwhelm the coil.

A 50/50 liquid is usually the best match. It gives:

• Steady flavour
• A moderate throat hit
• Good coil life

Nic salts also work well in lower powered pens if you prefer a smoother inhale or a slightly higher nicotine level. Pens tend to offer a little more vapour than pods, so your choice depends on whether you want smoothness (nic salts) or a sharper throat hit (freebase).

Sub ohm tanks require high VG e-liquids as these thick liquids work best with large mesh coils and higher wattages.

High VG liquids are ideal if you want:

• Dense clouds
• Warm vapour
• Long, flavourful inhales

These e-liquids pair well with lower nicotine strengths because sub ohm tanks produce far more vapour per puff.

Most disposables contained sweet, punchy nic salt blends with a smooth finish. If that is the experience you want to recreate with a refillable vape, nic salts will feel the most familiar.

Brands like Elux, IVG, OMG Liquids, Hangsen and similar ranges offer exactly the same style of bold fruit, ice blends and drink inspired flavours that disposable users enjoyed. These-liquids are ideal for pod systems and offer:

• Strong, instant flavour
• Smooth inhales
• Quick nicotine satisfaction
• Minimal coil stress

Many disposable fans wonder whether these brands still exist in the post ban landscape. The answer is yes. Elf Bar and Lost Mary now produce prefilled pod systems that include the same signature flavours but in rechargeable devices that comply with UK regulations. If you miss the simplicity and taste of disposables, these kits and their replacement prefilled pods offer the closest match.

Your nicotine level should match your smoking history or previous disposable use.

●    If you were a heavy smoker or used disposables frequently, a 20mg nic salt will feel most familiar.

●    If you prefer something lighter, 10mg nic salts offer the same smooth feel but with a gentler hit.

●    For sub ohm users, 3mg or 6mg is normally the best choice.

●    If you are reducing nicotine, 0mg shortfills (nicotine free) offer plenty of flavour without the extra kick.

Top Tip: If the vape feels too sharp, switch to nic salts or if it feels too soft or unsatisfying, try a 50/50 liquid for a little more impact.
