Best vape kits for heavy smokers: the power and battery picks
Only got a minute?
- Nicotine strength is capped at 20mg/ml in the UK, so a heavy smoker cannot go above that with a stronger bottle. Battery size, power and draw are what make the difference.
- Look for 1000mAh or more if you vape all day. The Voopoo Drag E60 has 2550mAh and the Eleaf iStick Power 2 has 5000mAh.
- Adjustable power lets you tune the hit. A kit that goes to 40W, 60W or 80W with a 0.6Ω to 0.8Ω coil gives a warmer, fuller draw than a fixed-output stick.
- A tight mouth-to-lung draw with 20mg nic salt is the closest match to a cigarette. Pair it with a big battery and you get a full draw and stamina in one device.
- Vaping Products Duty starts 1 October 2026, adding £2.20 plus VAT, so £2.64, to every 10ml of e-liquid. Heavy users get through the most liquid, so it matters most here.
Why heavy smokers need a different kind of kit
Most starter kit lists are written for someone who smoked ten a day. If you were on a pack or more, that advice lets you down in three ways: the battery goes flat mid-afternoon, the draw feels thin, and a fixed power output never gives you a full, warm draw.
Stronger e-liquid is not the answer, because every kit on this page takes the same 20mg nic salt. What changes is how much vapour each puff delivers, how warm it is, how it feels in the throat, and how many hours the device keeps going. Those come from three specs: battery capacity in mAh, adjustable wattage, and coil resistance in ohms.
This post is about the hardware. If you want a broader shortlist that is less focused on power and battery, our guide to the best vape kits for ex-smokers has it.

The three specs that actually matter
Battery (mAh)
A 20-a-day smoker takes roughly 200 to 300 draws a day on a cigarette, and an all-day vaper will run a 650mAh pod flat before the evening. 1000mAh or more gets most people through a day; 2500mAh and up gives headroom for higher power.
Power (watts)
Adjustable wattage lets you warm up the vapour and thicken the draw. 12W to 18W on a 0.8Ω coil, or 18W to 25W on a 0.6Ω coil, is the usual range for a mouth-to-lung kit.
Coil (ohms)
0.6Ω and above (typically 0.6Ω to 1.2Ω) is the mouth-to-lung range for 50/50 liquid: the higher end is a tight cigarette-style draw for 20mg salts, the 0.6Ω end a looser, warmer restricted draw for 10mg. Below about 0.6Ω is direct-to-lung for 3mg to 6mg from a 70/30 shortfill.
The usual pairing for a heavy smoker is either a mouth-to-lung pod at 20mg or a restricted direct-to-lung kit at 10mg, moving to true sub-ohm at 3mg to 6mg once they know that is their style. Our MTL vs DTL guide explains the difference in more depth.
Our picks for heavy smokers
Every kit below is refillable, takes a 2ml pod or tank, and is listed in our pod kits, advanced kits or mods range. They are ordered from the simplest to the most powerful.
1. Oxva Xlim Pro 2 Pod Kit 1300mAh
The best pod kit here for someone who wants a cigarette-like draw at 20mg with more battery than a typical pocket pod. The 1300mAh cell is a solid step up from the 650mAh to 1000mAh class, the airflow slider lets you go from tight mouth-to-lung to a slightly looser restricted draw, and the Smart Mode reads the coil and sets the wattage for you. It runs 5W to 30W in variable wattage mode, on either button press or draw activation.
Battery 1300mAh built in, USB-C. Pod 2ml refillable, top fill. Pods: 0.6Ω and 0.8Ω built-in coil. Best with 10mg to 20mg nic salt, 50/50 liquid.
2. Smok RPM40 Pod Kit 1500mAh
A compact pod mod that has been a heavy-smoker favourite for years because it does both jobs. At low power with an RPM mouth-to-lung coil it is a 20mg salt device; turn it up with a mesh coil and it becomes a warm restricted-lung kit for 10mg. The 1500mAh battery is enough for a full day at MTL power, and the wattage adjusts up to 40W.
Battery 1500mAh built in. Pod 2ml refillable. RPM coil range, up to 40W. Best with 10mg to 20mg nic salt.
3. Voopoo Drag E60 Pod Kit 2550mAh
Our top pick for most heavy smokers. The 2550mAh battery is nearly twice the size of a typical pod kit, the GENE chip runs from 5W to 60W, and the PnP Pod 2 takes the PnP coil range, roughly 0.15Ω to 1.2Ω. That means you can start on a tight MTL coil with 20mg salts and, if you later want a bigger cloud, drop in a 0.3Ω coil and a 6mg shortfill without buying another device. Adjustable airflow and an OLED screen round it off.
Battery 2550mAh built in, USB-C. Pod 2ml PnP Pod 2, side fill. Coils 0.2Ω and 0.3Ω included, compatible with PnP coils from roughly 0.15Ω to 1.2Ω. 5W to 60W. Best with 20mg salt on a higher-ohm PnP coil, 3mg to 10mg on the included coils.
4. Innokin Coolfire Z60 Zlide Top Kit 2500mAh
Innokin specialises in simple, tight-drawing mouth-to-lung kits, and the Coolfire Z60 is the big-battery version of that idea. A 2500mAh mod paired with the Zlide Top tank gives a tight, flavourful mouth-to-lung draw with adjustable power, and the top airflow design keeps it leak-resistant in a pocket. It suits anyone who wants a proper tank and replaceable coils rather than a pod.
Battery 2500mAh built in. Zlide Top tank, 2ml. Replaceable Innokin coils. Best with 10mg to 20mg nic salt.
5. Eleaf iStick Power 2 Kit 5000mAh
If battery is the only thing you care about, this is the one. A built-in 5000mAh cell is double the Drag E60 and will comfortably do two days of MTL vaping for most people. The GTL pod tank comes with 1.2Ω and 0.8Ω coils, both aimed squarely at nic salts and a cigarette-style draw, with lower-resistance GTL coils available for a looser hit. Power goes up to 80W, and the bottom airflow ring adjusts from wide open to very restricted.
Battery 5000mAh built in, USB-C 2A charging. GTL pod tank, 2ml. Coils 1.2Ω and 0.8Ω included, other GTL coils compatible. 1W to 80W. Best with 10mg to 20mg nic salt.
6. Freemax Twister 80W Kit with Fireluke 2 Tank
A pen-style kit with a twist-to-adjust base that goes from 5W to 80W and a 2300mAh battery. The Fireluke 2 is a mesh sub-ohm tank, so this is the kit for the heavy smoker who has tried a pod, found the draw too tight and wants warm, dense vapour from a 3mg to 6mg shortfill instead.
Battery 2300mAh built in. Fireluke 2 tank, 2ml. Mesh sub-ohm coils. 5W to 80W. Best with 3mg to 6mg shortfill, direct-to-lung.
7. Geekvape Max100 (Aegis Max 2) 100W Kit
The most powerful kit on the list, and the one for someone who wants a device they will never worry about dropping. It takes a single 21700 or 18650 battery, so you can carry a spare and never be flat, runs up to 100W, has a colour screen, and is rated IP68 against water, dust and shock. The Z Subohm tank is a direct-to-lung tank for low-strength liquid. Our box mod kits guide compares it with other mods.
Battery single 21700 or 18650, sold separately. Z Subohm tank, 2ml. Mesh sub-ohm coils. Up to 100W. Best with 3mg to 6mg shortfill.

| Smok RPM40 | 1500mAh | 40W | RPM range | 10mg to 20mg salt |
| Voopoo Drag E60 | 2550mAh | 60W | PnP, roughly 0.15Ω to 1.2Ω | 3mg to 20mg, coil dependent |
| Innokin Coolfire Z60 | 2500mAh | 60W | Zlide Top, Innokin coils | 10mg to 20mg salt |
| Eleaf iStick Power 2 | 5000mAh | 80W | 1.2Ω, 0.8Ω GTL, others compatible | 10mg to 20mg salt |
| Freemax Twister 80W | 2300mAh | 80W | Fireluke 2 mesh | 3mg to 6mg shortfill |
| Geekvape Max100 | 21700 / 18650 | 100W | Z Subohm mesh | 3mg to 6mg shortfill |
All pods and tanks are 2ml, the UK legal maximum. Highlighted row is our overall pick for a heavy smoker who wants one device that can grow with them.
Pod, tank or box: which style suits a heavy smoker?
Big-battery pod kits like the Drag E60 and RPM40 are the sweet spot for most people. They take nic salts, the pods are simple to replace, and you still get adjustable power. If you get through a lot of liquid, a pod with replaceable coils rather than a sealed pod keeps running costs down.
Built-in battery tank kits like the Coolfire Z60 and iStick Power 2 give you a bigger cell and a proper tank without the complexity of external batteries. They are heavier in the pocket but go longer between charges.
Box mods with external batteries like the Max100 are for the heavy smoker who has already settled into direct-to-lung vaping at 3mg to 6mg. Swapping in a charged cell ends battery anxiety, but the tanks want thick 70/30 shortfill and low strength. Our comparison of pod systems vs box mods goes into the trade-offs.
Setting up for the first week
- 1
Start at 20mg salt on a tight draw. A very heavy habit, 20 plus a day, sits at 20mg in the usual strength table, and a heavy habit at 10mg to 20mg. Use the highest-ohm coil in the box and the airflow half closed. Our guide to how much nicotine to vape covers the numbers.
- 2
Prime the coil and wait five minutes. Fill the 2ml pod, let the cotton soak, then start at the bottom of the coil’s wattage range. Burning a coil on day one is an easy way to write off a new kit.
- 3
Nudge the power up a watt at a time. Stop when the vapour is warm and the draw feels full. On a 0.8Ω coil that is usually 12W to 18W; on a 0.6Ω coil it is nearer 18W to 25W.
- 4
Charge daily, not overnight. Even a 2500mAh battery is happier charged daily than run flat. Use the USB-C cable supplied with the kit in a standard low-output USB plug or a computer port, avoid fast-charge bricks, and do not charge unattended overnight.
Running costs for a heavy user
A heavy vaper is also a heavy e-liquid buyer, which is why the Vaping Products Duty matters more to you than to anyone else. From 1 October 2026 every 10ml of e-liquid carries £2.20 of duty plus VAT, which is £2.64 at the till. A typical pod-kit vaper uses 10ml to 15ml a week, and a heavy user sits at the top of that range or above, so it adds up. Pre-duty stock is on sale until 31 March 2027.
The kit choice affects cost too. A replaceable-coil device is cheaper to run than a sealed-pod one over a year, and a shortfill at 3mg to 6mg is cheaper per ml than 10ml salts, which is one reason many long-term heavy vapers drift towards restricted or direct-to-lung kits over time. Every order also earns 1.8 reward points per £1, which adds up quickly for someone buying liquid every week.

Quick answers
Can I get e-liquid stronger than 20mg for a heavy habit?
No. 20mg/ml is the UK legal maximum and anything sold above it is illegal. The way to get a fuller hit is a tighter draw, a slightly warmer coil and a device that does not run out, which is what the picks above are chosen for.
Is a bigger battery always better?
For a heavy user, mostly yes, but it comes with weight and size. The Eleaf iStick Power 2 at 5000mAh is noticeably chunkier than the Oxva Xlim Pro 2 at 1300mAh. Around 2500mAh is a good balance.
Should a heavy smoker go straight to a sub-ohm box mod?
Usually not. Sub-ohm kits want 3mg to 6mg liquid, and the usual strength table puts a heavy habit at 10mg to 20mg salt on a tight draw. Start with a big-battery pod kit like the Drag E60 and move to sub-ohm later if you want bigger clouds.
Why is my pod only 2ml when I vape so much?
UK law caps nicotine-containing pods and tanks at 2ml. Every kit on this page is 2ml. Keep a 10ml bottle with you rather than looking for a bigger tank.
How long does a 2ml pod last a heavy user?
It depends on power and draw length. A 10ml bottle gives roughly 600 to 1,500 puffs across the range of kits here, so a 2ml fill on a mouth-to-lung coil is a day or less for a heavy vaper. On a sub-ohm coil at higher power it can go in a couple of hours, which is why sub-ohm users buy shortfills.
