Choosing between refillable pod kits can feel like comparing a lot of near-identical devices. This guide puts the main refillable kits in our shop side by side, using battery size, tank size and draw style, so you can narrow the choice quickly. Vaping is for adults and is best suited to people who already smoke or use nicotine.
What All These Kits Have in Common
Every kit in this comparison is refillable, uses a 2ml tank or pod (the UK maximum), and is designed for nic salt e-liquid at a strength of up to 20mg/ml. Each is listed in our shop in three strengths: nicotine-free, 10mg and 20mg. That means the main differences are battery capacity, airflow and features. If you are still deciding between refillable and prefilled, read our prefilled pod kit guide first.

Which Kit for Which Vaper?
Small and light: Aspire Flexus and Uwell Caliburn G3
The Aspire Flexus has the smallest battery here, which makes it a pocket-friendly device for lighter use. The Uwell Caliburn G3 adds a bigger battery and a fixed MTL draw, so there is nothing to adjust, which some beginners prefer.
Middle of the range: SMOK Novo 5, Innokin Sceptre, Geekvape Wenax Q
These three have batteries between 800mAh and 1000mAh, a 2ml tank and an MTL draw, so they suit people who vape through the day but still want a manageable size. Compare the SMOK Novo 5, the Innokin Sceptre and the Geekvape Wenax Q.
Bigger battery and more control: Vaporesso Luxe X2, OXVA Xlim Pro 3, Voopoo Argus P2
If you want longer between charges, or the option to tune the vape, these are the stronger choices. The Vaporesso Luxe X2 uses a mesh coil, the OXVA Xlim Pro 3 offers 5-30W adjustment, and the Voopoo Argus P2 pairs an 1800mAh battery with adjustable airflow.

How to Decide in Three Steps
- Decide how often you vape. Light users can pick a smaller battery. Heavy users should pick a bigger one.
- Decide how much control you want. Fixed MTL is simple. Adjustable airflow or wattage gives more options.
- Pick your strength and flavour. Then fill, soak and enjoy.
Understanding the Specs
Battery capacity is shown in mAh. A bigger number usually means longer between charges, but it also tends to mean a larger device, so choose the capacity that matches how often you can charge. Draw style describes how the vapour is pulled: MTL (mouth-to-lung) is a tight draw similar to a cigarette, and it is the style nic salts are designed for. Adjustable airflow lets you loosen the draw a little, which some people find more comfortable once they are used to the device.
A mesh coil spreads the heat across a larger surface, which can give smoother flavour and more even vapour, while an adjustable wattage range lets you fine-tune the output. These are extras rather than essentials, and a simple fixed-draw kit can be just as satisfying for a new vaper.
Price, Value and Spares
Larger batteries and extra features generally cost more, but a kit that suits you and lasts is better value than a cheap one you do not enjoy. Before you buy, check that replacement pods or coils are easy to find for your chosen model, since you will need them regularly. Browse our devices and coils category for spares, and keep one set in reserve so you are never left without a working pod.
Frequently Asked Questions
Does a bigger battery mean more puffs?
It means longer between charges, but how long a fill lasts depends on how you vape.
Which kit is best for beginners?
A simple fixed-draw MTL kit with a mid-sized battery is a sensible start.
Can I use these with shortfills?
No. Use nic salt in these devices. Shortfills are made for sub-ohm tanks.
