Big puff rechargeables look similar on a shelf, but the specifications vary. This guide compares the big puff rechargeable kits in our shop by battery size and rated puffs, so you can decide which one fits how you vape. If you are new to the format, start with our guide to big puff rechargeable vapes. Vaping is for adults and is best suited to people who already smoke or use nicotine.
Read the Puff Ratings Carefully
Every kit below has a 2ml refillable tank, which is the maximum allowed in the UK. The “puffs” figure is the manufacturer’s rating based on repeated refills, not how many puffs one tank will give. A higher number does not mean the tank holds more liquid. Treat the rating as a rough guide to how long the device is designed to last. The kits are rechargeable, so they are not single-use devices, as explained in our disposable vape ban guide.

Which One Should You Pick?
Maximum battery: Fumot RandM Tornado 28K
The Fumot RandM Tornado 28K has the largest battery in the list at 850mAh, so it is the pick for heavy daily vapers who dislike charging. Choose 10mg or 20mg.
The 18,000 puff pair: Elux Legend and Crystal Prime
The Elux Legend 18000 and the Crystal Prime 18000 have the same listed battery and puff rating, so the choice comes down to brand preference and strength. Both come in 10mg and 20mg.
The 15,000 puff group
The Aroma King AK Bar 15000, the SKE Crystal Bar 15000 and the Hayati Pro Ultra 15000 each have a 650mAh battery, so compare strength and look.
Lighter-use options: Elf Bar AF9000, Lost Mary BM6000, IVG Bar 3500
If you want a smaller device, the Elf Bar AF9000, the Lost Mary BM6000 and the IVG Bar 3500 have batteries of 500 to 600mAh and lower puff ratings. They suit lighter users.
Choosing a Strength
Every kit here is listed at 10mg and 20mg nic salt. Twenty mg is the UK maximum and is typical for people who used strong disposables. Ten mg is gentler. Not sure? Read our nicotine strength guide. If you want a nicotine-free option, look at the pod kit category, where many kits are available at 0mg.
What to Fill It With
These devices take nic salt in 10ml bottles. Check our best nic salt e-liquids guide and our brand comparison for ideas, or browse the nic salt range.
Care, Charging and Recycling
- Fill to the line only and let the cotton soak before use.
- Avoid chain vaping, which can overheat the coil.
- Charge with a good cable and plug, such as our USB-C wall charger plug, and never leave a battery charging unattended for long.
- Protect it with a silicone sleeve and carry it in a travel case.
- Recycle old devices at a proper battery or electrical recycling point.
More advice is in our pod kit care guide.
Size, Weight and Everyday Use
A bigger battery is not always better for everyday use. Larger devices are heavier and bulkier in a pocket, and if you only vape lightly, you may never get the benefit of the extra capacity. If you mostly vape at home or at a desk, capacity matters more than size. If you carry the device everywhere, a smaller kit may be more comfortable. Think about where you usually vape, how often you can plug in, and whether you prefer to refill every day or less often.
How Big Puff Rechargeables Differ From Pod Kits
A standard refillable pod kit is usually smaller and cheaper, with a modest battery and a pod you replace. A big puff rechargeable is built for people who want fewer charges and a larger overall device. If you like the idea of a compact kit, our refillable pod kit comparison covers the alternatives, and the prefilled pod kit guide explains sealed pods.
