SMOK Mag V8 Mod Vape Kit

Introduction

The SMOK Mag V8 vape kit is a refillable sub-ohm box mod with no screen and no wattage buttons. It reads the coil and fires the matching power, up to 70W. £24.99, best for vapers stepping up from a pod to DTL clouds without learning settings.

Key Facts

• The SMOK Mag V8 is a semi-regulated mod that outputs up to 70 watts with no screen and no adjustable wattage.
• The SMOK Mag V8 takes one external 21700, 20700 or 18650 battery, which is not included.
• The SMOK Mag V8 kit includes the TFV-Mini V2 tank with a 2ml UK capacity.
• The SMOK Mag V8 uses SMOK Mini V2 coils, also sold as Baby V2 coils.
• The kit ships with an S1 0.15 ohm coil fitted and an S2 0.15 ohm coil spare.

Key Specs Customers Check

• Output: up to 70W, not adjustable. The mod matches power to the coil, so there is nothing to set.
• Battery: one 21700, 20700 or 18650, sold separately. A 21700 holds full output the longest.
• Screen: none. Five clicks on, five clicks off, and no menus at all.
• Tank: TFV-Mini V2, 2 ml. UK law caps tanks at 2ml, so this is the legal maximum.
• Coils: S1 and S2, both 0.15 ohm. Sub-ohm means under 1 ohm, built for clouds, not a cigarette-style draw.
• Fill and airflow: top fill, three-slot ring. Close the ring for flavour, open for clouds.
• Charging: USB port on the mod. A separate battery charger is faster and safer for this type of mod.
• Size and fitting: 91.3 x 59.5 x 38.7mm, 510 thread. Curved grip shape, and any 510 tank screws screw on flush.

Pick Your Inhale: This Is a DTL Kit

The SMOK Mag V8 is direct-to-lung only. DTL means drawing vapour straight into the lungs like a deep breath, giving warm, thick clouds. MTL, the tight cigarette-style puff pods use, is not what this kit does.

Both supplied coils sit at 0.15 ohm. The S1 single mesh runs hotter and peaks near 70W for maximum vapour. The S2 quad has tighter airflow and a cooler draw. Vapers on the Planet of the Vapes forum prefer the S2 for flavour and report the S1 running too hot, so switch coils if the first feels harsh.

Key Features of the SMOK Mag V8 Mod

• Nothing to misconfigure: the chip reads coil resistance and fires the matching power.
• Swappable battery: a flat cell is replaced in seconds, so the kit never sits on charge.
• Output tracks the battery: power peaks on a full cell and tapers as it drains, a rough gauge in place of a screen.

Coils and E-Liquid Pairing

Sub-ohm coils need thick e-liquid. Use 70% VG or higher 100ml shortfill e-liquid with a freebase nicotine shot, freebase being standard nicotine rather than nic salt.

At 0.15 ohm, the device delivers a lot of vapour per puff, so 3mg suits most DTL vapers and 6mg is the practical ceiling. Nic salts at 10mg or 20mg are made for tight MTL pods and will feel harsh, and thin 50/50 liquid leaks through the wicking ports.

Battery, Coil Life and Running Cost

Buy the battery separately. A 21700 such as the Molicel P42A 21700 is the recommended pairing, as forum owners report 18650 cells struggle to hold full output with 0.15 ohm coils. Expect about a day of moderate DTL use. Compare 18650 and 21700 vape batteries first.

Coil life runs long by sub-ohm standards. Forum owners report six weeks on an S1, helped by its large wicking ports, though sweet dessert liquids cut that to one or two weeks. At £3.33 a coil and around £10 to £15 per 100ml of shortfill, a week lands near £4 to £6.

Compatibility and Refills

TFV-Mini V2 and TFV8 Baby V2 are the same coil family under two names, so SMOK Mini V2 replacement coils fit this kit. The range runs A1 0.17 ohm, A2 0.2 ohm, A3 0.15 ohm, K1 0.2 ohm, K4 0.15 ohm, S1 0.15 ohm and S2 0.15 ohm.

One limit: the A and K coils are rated 80W to 140W, and this mod stops at 70W, so stick to the S1 and S2. The older TFV8 Baby, X-Baby and Baby-Q2 coils are a different fitment and will not seal.

How to Set It Up

1. Fit the coil into the tank base and screw the base on.
2. Drip e-liquid onto every visible cotton port, then fill through the top cap.
3. Wait 10 to 15 minutes before the first puff, as skipping this is the main cause of a burnt coil.
4. Insert one 21700 flat negative end down, or fit an 18650 inside the supplied adapter first.
5. Click the fire button five times, set the airflow two-thirds open, then draw.

How to Make It Last Longer

• Never dry fire. Keep the tank above a quarter full, as an exposed wick burns in one puff.
• Leave gaps between puffs. Chain vaping at 70W cooks the cotton fastest.
• Rinse the tank in warm water and air dry at every coil change.
• Check the battery wrap for nicks, and replace any damaged cell.

Price Comparison

Checked live in August 2026: Eco Smok £26.00 in stock, eCigarette Outlet £34.99 sold out, UK Vape World £29.99 sold out. It is £24.99 here, in stock in all four colours.

It is also cheap to run against other vape mods, as the S1 and S2 last longer than most SMOK coils. Versus the SMOK Fortis, which uses the identical tank and coils, the Mag V8 costs less but gives up the screen and wattage control.

Best Colours

Black Red is the safest buy and the most searched, as the dark body hides scuffs and suits an adult ex-smoker who wants a device that looks like hardware. Red Gold and Silver Blue read smarter and suit collectors who own several mods. Black Prism Rainbow is the loudest, and owners note it looks better in person than in photos.

SMOK Mag V8 FAQ

Does the SMOK Mag V8 have a screen?

No. The Mag V8 has no display and no wattage buttons. It is a semi-regulated mod that reads coil resistance and fires the matching power automatically, up to 70W. Five clicks switch it on and off.

Is a battery included with the SMOK Mag V8?

No, the battery is sold separately. The kit needs one 21700, 20700 or 18650 cell, and an 18650 adapter sleeve is in the box. An 18650 works but gives lower, shorter-lived output, so a 21700 is the better match.

Which coils fit the SMOK Mag V8?

SMOK Mini V2 coils, also branded Baby V2, fit this kit. Use the S1 0.15 ohm or S2 0.15 ohm, as those match the 70W ceiling. The A, K and Baby-Q2 coils are rated far higher or are a different fitment.

What is the difference between the S1 and S2 coil?

Both are 0.15 ohm. The S1 is a single mesh coil that runs hotter with more airflow and bigger clouds. The S2 is a quad coil with a tighter draw, cooler vapour and flavour that many forum owners rate higher.

How long do the coils last?

Around one to two weeks on sweet dessert e-liquid, and up to six weeks on lighter fruit or menthol, per owner reports. Signs a change is due are a burnt taste, weaker flavour or gurgling.

What e-liquid should I use in the SMOK Mag V8?

Use 70% VG or higher shortfill at 3mg to 6mg freebase nicotine. Sub-ohm coils vaporise a lot per puff, so high-strength nic salts made for pods feel harsh and thin 50/50 liquid can leak.

Is the SMOK Mag V8 good for a beginner?

It suits a beginner to sub-ohm vaping who wants no settings, but it is not the right first device for someone new to vaping. The DTL-only draw and 0.15 ohm coils are a big step up, and an MTL pod kit is the better starting point.
