SMOK mod range compared, one battery or two

Search for a SMOK mod in the UK and the results are shop listings and marketplace pages, many of them led by the brand’s pod kits. None of them tells you which box to pick. The current SMOK mod line-up comes down to four models, and one spec divides them before any other, the number of batteries inside the case. This comparison sets the four side by side on the vapour they can produce, using SMOK’s own product pages and retailer listings.

Which SMOK mod to choose, the short answer

For dense clouds without the bulk, the Mag Solo is the most balanced of the four, with 100 W from a single 21700, 20700 or 18650 cell. The X-Priv Solo is the smallest, capped at 80 W on one 18650. To go past 200 W you need one of the dual 18650 models, the X-Priv Plus (225 W) or the Morph 3 (230 W).

Between those two, the Morph 3 wins for anyone who likes fine control, because SMOK lists a temperature control mode on top of variable wattage.

The four SMOK mod models side by side

Figures come from SMOK’s product pages and from retailer listings, including evaps.fr, cigaretteelec.fr and the Vaping360 product database. A spec only appears in the table when at least two sources agree on it.

Spec	X-Priv Solo	Mag Solo	X-Priv Plus	Morph 3
Batteries (not included)	1 × 18650	1 × 21700, 20700 or 18650	2 × 18650	2 × 18650
Power	5 to 80 W	5 to 100 W	5 to 225 W	Up to 230 W
Modes listed by SMOK	Variable wattage	Variable wattage	Variable wattage	Variable wattage and temperature control
Screen	Touchscreen	0.96 inch TFT	Large screen	0.96 inch TFT
Charging	USB-C	USB-C	USB-C, 2 A according to SMOK	USB-C, 2 A
Kit tank	TF-D Subtank, D-Coil heads	T-Air Subtank, TA coils	TF-D Subtank, D-Coil heads	T-Air Subtank, TA coils

All four use a 510 thread, so buying the mod on its own leaves the choice of tank open.

One battery or two, what really separates each SMOK mod

Battery count sets the power ceiling, which in turn decides which coils make sense and how much liquid each puff vaporises. The three cases below cover the whole range.

X-Priv Solo, the most compact option

SMOK calls it the world’s smallest sub-ohm device, a manufacturer claim this comparison cannot verify. Its dual touch display, magnetic interchangeable battery cover and vibration alerts make it the better equipped of the two single-battery boxes in the range.

Its 80 W is enough for the D-Coil heads of the TF-D Subtank supplied in the kit. It leaves little headroom, though, for a rebuildable atomiser built at a very low resistance.

Mag Solo, one battery in the size you prefer

The Mag Solo takes a 21700, 20700 or 18650 cell, the last one through an adapter. A 21700 is physically larger and usually offers more capacity, which matters on a box that reaches 100 W.

Its zinc alloy shell with a leather-style finish carries on the look of earlier Mag models. The kit pairs it with the T-Air Subtank and its 0.2 and 0.4 ohm TA coils, both built for direct lung vaping.

X-Priv Plus and Morph 3, the two dual-battery boxes

With two 18650 cells the load is shared across two batteries, which opens the range beyond 200 W. The X-Priv Plus stands out for its large screen, the Morph 3 for its temperature control mode and an adaptive power function that, according to SMOK, adjusts output to the remaining charge to keep delivery stable.

Power and clouds, what the watts on a SMOK mod change

A mod does not make vapour, it powers the coil. On a low-resistance coil, higher power vaporises more liquid per puff and gives a bigger cloud, as long as the cotton stays saturated.

The maths also explains the line between one cell and two. At 80 W, a battery with a nominal 3.6 V has to deliver around 22 A, that is 80 divided by 3.6, before any circuit losses. At 225 W on a single cell it would take more than 60 A, which is why the most powerful SMOK mod models use two cells that share the load. Before buying batteries, check that their continuous discharge rating covers the power you plan to use.

The liquid matters as much as the mod. A high-VG e-liquid generally gives denser vapour at the same settings, as shown in our Fruizee Bloody Summer vapour density comparison, where one recipe changes its cloud with its ratio.

One last point concerns the tank. SMOK quotes 5 ml for the T-Air Subtank, which is the standard international version. In the UK, refillable tanks are limited to 2 ml and nicotine e-liquid to 20 mg/ml in 10 ml bottles, so the capacity printed on a UK retailer’s listing is the one that applies.

Verdict by cloud profile

The best model depends less on maximum power than on the power you will actually use. Here is how we rank the four by vaping style.

Dense clouds in a smaller box

The Mag Solo is our pick. Its 100 W handles the 0.2 and 0.4 ohm coils of the kit with room to spare, and the option of a 21700 gives it the edge over the X-Priv Solo. The X-Priv Solo still makes sense for anyone vaping at moderate power who values the smallest size.

Big clouds and rebuildable atomisers

For a low-built atomiser or a dual-coil deck, the two dual-battery boxes are the obvious route. We name the Morph 3 the winner, because the temperature control listed by SMOK adds an adjustment the X-Priv Plus does not claim. A liquid designed for that draw, such as the recipes in our Juice Heroes flavour comparison, gets the most out of it.

Tight mouth-to-lung draw

None of the four boxes is designed for this style, and their kit tanks all aim at direct lung vaping. A pod kit is a better match, with a nic salt liquid such as those in our TornadoLiq nic salt comparison.

FAQ

Five questions that retailer listings tend to skip.

Do SMOK mods come with batteries?

No, none of the four models compared here. Retailer listings state that batteries are sold separately, as is any external charger. One or two cells suited to the power you have in mind are therefore needed as well.

Do the two batteries in a dual mod need to match?

Yes. Two cells of the same model and age, charged and used together, discharge evenly. Pairing a new cell with a worn one unbalances the load between them.

Can I fit a different tank from the one in the kit?

Yes, thanks to the 510 thread shared by all four boxes. Just check that the tank diameter does not exceed the width of the top plate, otherwise it overhangs the mod.

What does temperature control mode do?

It caps the temperature of the coil rather than the power sent to it. It only works with compatible wire such as nickel, titanium or stainless steel, and does not apply to standard kanthal coils.

How do I charge the batteries in a SMOK mod?

All four models charge through a USB-C port. An external charger is still the more flexible option, as it lets you check each cell’s condition and keep the mod in use while the batteries charge.

SMOK mod, choose the battery count before the watts

The SMOK range reads as two families. One battery for the compact boxes, from 80 to 100 W, two batteries to pass 200 W. Our verdict puts the Mag Solo first for dense clouds in a reasonable size, and the Morph 3 ahead of the X-Priv Plus for anyone who likes to fine-tune.

Whichever SMOK mod you choose, the final cloud will depend as much on the e-liquid ratio and the coil as on the wattage on screen, a balance we compare figure by figure across the site.
