Dotmod coils, an investigation into compatibility

Two 0.3 ohm heads, same brand, same brass finish, and yet one refuses to seat in the pod that takes the other. Buying Dotmod coils without knowing which generation your device belongs to is a quick route to that kind of return. The brand built its range in waves, and each wave kept its own fitting. This investigation cross-checks the product listings published online to trace those lines, value by value.

Which Dotmod coils fit which device

The right Dotmod coils depend first on the generation of the device, and only then on the resistance value. Three main families share the range, the dotAIO Coils, the dotCoils and the dotStick Coils.

The original dotAIO and the dotAIO SE take the dotAIO Coils. The dotAIO V2 and six other devices from the brand (dotAIO V2 Lite, dotAIO V3, dotTank 25 mm, dotTank Max, dotStick Revo, dotPod Max) move to the dotCoils. As for the original dotStick, it keeps its own dotStick Coils.

A fourth reference, the dotCoil x SteamCraft, also sits in the catalogue, with no compatibility details on its category page. This guide therefore sticks to the three documented families.

Three lines of Dotmod coils, three fittings

The brand name is shared, the fitting is not. Each family matches its own line of devices and its own base, which is why a head cannot cross from one line to another, even at the same value.

dotAIO Coils, the first generation

Designed for the dotAIO and the dotAIO SE, these heads pair a brass body with 316L stainless steel wire. Listings offer them in three values, a 0.3 ohm mesh (20 to 35 W), a 0.7 ohm mesh (14 to 20 W) and a 1.6 ohm ceramic head (8 to 14 W).

They come in boxes of five. None of the listings we read names the dotAIO V2 among compatible devices, which is enough to rule them out for the second generation.

dotCoils, the most widely shared platform

The dotCoils use a single mesh and a brass connection, and they also come in packs of five. They are made in 0.15, 0.3, 0.6 and 0.7 ohm. For the 0.3 ohm, listings agree on 25 to 40 W, for the 0.6 ohm on 18 to 22 W and for the 0.7 ohm on 14 to 20 W.

This family carries the longest compatibility list in the range. It covers AIO pods as well as dotTank tanks, which makes it the most versatile replacement head the brand makes.

dotStick Coils, a line of their own

The dotStick Coils fit the original dotStick. They are mesh heads, made in 0.4, 0.7 and 1 ohm, and sold in packs of five.

Despite its name, the dotStick Revo does not belong to this family. It appears on the dotCoils list, and a retailer’s customer service confirms that dotStick Coils do not suit it.

The compatibility table, checked listing by listing

For each family of Dotmod coils, the table below only keeps a compatibility confirmed by the brand or by two matching retailers. A compatibility quoted by a single listing is left out.

Family	Values found	Devices listed
dotAIO Coils	0.3 Ω mesh, 0.7 Ω mesh, 1.6 Ω ceramic	dotAIO, dotAIO SE
dotCoils	0.15 Ω, 0.3 Ω, 0.6 Ω, 0.7 Ω (mesh)	dotAIO V2, dotAIO V2 Lite, dotAIO V3, dotTank 25 mm, dotTank Max, dotStick Revo, dotPod Max
dotStick Coils	0.4 Ω, 0.7 Ω, 1 Ω (mesh)	dotStick

Sources agree on the families. They differ far more on one specific value, the 0.15 ohm, and on wattage ranges.

The 0.15 ohm trap

Within the dotCoils family, only one value does not fit everywhere. Each listing flags it in its own way, and their exclusion lists only partly overlap.

The brand’s French distributor page marks the 0.15 ohm as incompatible with the dotStick Revo and its V1.5 version, and one retailer listing repeats both exclusions. Another listing restricts it to the dotAIO V2 and the dotTank Max, while a third warns against using it on the dotPod Max V1.5.

None of these pages explains the exclusion. They do show that this head asks for far more power than the rest of the family, above 60 W, where the 0.3 ohm tops out at 40 W.

When listings for the same Dotmod coils disagree

Cross-checking product pages reveals gaps that none of them flags. They do not change compatibility, but they muddle the settings and the search for the right reference.

Wattage ranges that move

For the 0.15 ohm, two listings give 60 to 80 W and three others 70 to 90 W. The 0.3 ohm dotAIO mesh is rated 20 to 35 W by two listings and 25 to 35 W by a third. The 1 ohm dotStick Coil shifts from 10 to 12 W at one seller to 10 to 15 W at another.

Values announced, then missing

One page lists four dotCoil values in its description, yet its selector offers only three, without the 0.7 ohm. A retailer repeats the same omission. On the dotAIO side, one listing shows a 1.6 ohm in its table and a 1.2 ohm in its selector, and another describes a 1.2 ohm Clapton head missing from every other page.

Start from the lowest figure

With such gaps, the most cautious lower bound is the place to start, which means 60 W for the 0.15 ohm and 20 W for the 0.3 ohm dotAIO mesh. Stepping up a few watts at a time then finds the setting without overheating a head whose listing was approximate.

Identify your device before you buy

The name of the range is not enough to choose Dotmod coils. The pairs dotStick and dotStick Revo, dotAIO and dotAIO V2 carry similar names yet use different coil families.

Check the version on the box or in the device manual, then match it against the compatibility list on the listing. The same puzzle exists elsewhere, as our guide to both Z coil families at Geekvape shows.

A device that shows no reading after a new head goes in is often pointing to a coil that is not fully seated or simply the wrong one. Our guide to the no coil detected message walks through that diagnosis.

FAQ

The questions that come up when replacing a head or moving from one Dotmod device to another.

How do you change a Dotmod coil without burning it?

Empty the cartridge, pull out the old head, then drop a few drops of e-liquid onto the exposed cotton of the new one. Refit, fill and let the wick soak for a few minutes before the first puff, starting at the bottom of the wattage range.

Are dotCoil V2 and V3 different from dotCoils?

Those names appear at some retailers, on very similar values and devices. One UK listing describes the V3 as an upgraded version with revised cotton, without putting a figure on the difference. Only the device list on the listing settles it for a given model.

Will a Dotmod head fit another brand’s pod?

Dotmod France’s own dotStick Coil listing describes them as compatible with SMOK Nord coils, a claim two retailer listings also make. The seal of such a pairing, however, is documented nowhere, so sticking to the listed devices is the safer choice.

Which value suits a nicotine salt e-liquid?

The higher values, 0.7 ohm in the dotCoils and 1 ohm in the dotStick Coils, are presented for mouth-to-lung vaping and stronger nicotine e-liquids. In the UK, nicotine e-liquid is capped at 20 mg/ml in bottles of up to 10 ml, and refillable tanks are limited to 2 ml. The 0.15 ohm head targets direct lung vaping at high power instead.

How long does a replacement head last?

No lifespan holds from one listing to the next, because it depends on the e-liquid and the wattage. A very sweet recipe tends to clog the wick faster, and a burnt taste or a flat flavour signals that it is time for a change.

Choosing Dotmod coils by generation, then by value

Getting the questions in the right order matters most. The device generation points to the family, the listing confirms compatibility, and the value then follows the draw you want. Only the 0.15 ohm calls for one more check, and the most cautious lower bound is the place to start.

The dotAIO Coils use 316L stainless steel wire, an alloy widely used on rebuildables, and our guide to vape coil wire covers how it behaves. Well chosen Dotmod coils come down to a correctly identified generation, a method that holds for any vape built around swappable heads.
