# Lost Vape coils: UB Max, Ultra Boost, UB Lite > UB Max, Ultra Boost V2 and UB Lite: three ranges of Lost Vape coils not to be confused. Values, wattages and compatible devices, family by family. Searching for **Lost Vape coils** on a British shop brings back several catalogues with names that look almost interchangeable, UB Max, Ultra Boost and UB Lite among them, without any listing making it clear which one belongs to which device. The risk is simple enough: ordering a reference that will not physically go into the cartridge you already own. These ranges are not interchangeable. Each targets a specific platform, with its own scale of values and its own wattage bracket. The reliable marker is never the name of the device, it is the name of the cartridge or pod fitted to it. ## Three families of Lost Vape coils, three platforms The confusion comes from a marketing vocabulary that repeats itself from one range to the next. A UB Max has nothing to do with an Ultra Boost, even when the two display the same resistance in ohms on the front of the packet. - **UB Max**: fitted to the Centaurus tanks and to the Thelema Centaurus, oriented towards high power. - **Ultra Boost V2**: the historic platform of the Thelema and the Q-Ultra, and the broadest catalogue of the three. - **UB Lite**: reserved for the Ursa Mini, the only family that pod accepts. Checking the cartridge before ordering removes the bulk of the errors. A UB Max part simply does not clip into a seat designed around the Ultra Boost, whatever the two boxes look like side by side. The manufacturer maintains these catalogues in parallel rather than unifying them, unlike brands that bet on a single connection across an entire range. Each platform corresponds to a generation of device and to a favoured use, from the compact pod to the more versatile mod. British shelves complicate that picture slightly, and it is worth saying so plainly. Alongside the three families above, UK retailers also list UB Pro and UB Ultra references, and stock coils for the Thelema E, the Ursa Nano series and the Orion GO DNA. That breadth is exactly why the cartridge name, and not the family name you half remember, is the thing to check. ## UB Max, the high power platform The UB Max series targets devices able to deliver plenty of watts into a wide mesh strip. Three references cover most direct lung use, and they sit at the top of the range in every sense. The X1 in 0.15 ohm is published between 80 and 120 W, the X2 in 0.20 ohm between 60 and 80 W and the X3 in 0.30 ohm between 40 and 60 W. All three aim at a very airy direct draw with a large volume of vapour. A device set below the lower figure of those brackets produces a flat taste and incomplete heating. Pushing a new part to the upper figure from the outset does the opposite damage and accelerates the wear on the cotton before it has settled. British listings for this family are also where you are most likely to meet a V1 and a V2 of the same reference. As with any revision, the published bracket is the one printed on the box in your hand, not the one you remember from a previous order. ## Ultra Boost V2, the widest catalogue This is the platform fitted to the Thelema and the Q-Ultra, and the one offering the largest number of different values. Five references between them cover every style of draw, from the loosest direct to a properly tight one. The M3 in 0.15 ohm is published between 40 and 70 W, the M4 in 0.20 ohm between 40 and 60 W, the M1 in 0.30 ohm between 30 and 40 W and the M2 in 0.60 ohm between 20 and 28 W. The MTL reference in 1.0 ohm drops to 8 to 15 W, built for a tight draw. That spread is the genuine strength of the Ultra Boost V2. One device covers the entire span of uses without ever changing cartridge, provided you pick the value that matches the liquid you intend to put in it. The liquid conditions the result quite as much as the setting does. The low values in this family call for a fluid liquid, rich in vegetable glycerine, to irrigate the mesh strip properly. The higher values in 0.60 and 1.0 ohm tolerate a thicker liquid and are the ones British vapers usually pair with nicotine salts, within the 20 mg/ml ceiling that applies to nicotine containing liquid sold in the United Kingdom. Get that pairing backwards and the symptoms are immediate. A liquid that is too thin on a high value floods the wick and produces spitting. A liquid that is too thick on a low value dries the strip out and burns it prematurely. ## UB Lite, the only option on the Ursa Mini The Ursa Mini pod accepts a single family, which simplifies the choice while leaving very little room for error on the reference itself. Seven values are available for that one format. The L7 in 0.30 ohm runs between 32 and 40 W, the L1 in 0.40 ohm between 20 and 30 W and the L10 in 0.60 ohm between 12 and 21 W. Then come the L3 in 0.80 ohm between 12 and 17 W, the L6 in 1.0 ohm between 10 and 15 W, the L8 in 1.2 ohm between 9 and 11 W and the L5 in 1.4 ohm between 8 and 10 W. That span takes you from restricted direct lung all the way to a very tight draw on a genuinely compact pod. Few product pages make anything of it, even though it is on its own a strong argument for the Ursa Mini as an everyday device. ## Checking compatibility before ordering Lost Vape coils Three checks are enough to rule out almost every ordering mistake, whichever family you are aiming at. They take under a minute and they save you a pack of five unusable parts. - Note the exact name of the cartridge or pod, not the name of the device holding it. - Compare that name against the families before validating the order, and read the revision letter if the listing shows one. - Confirm that the published wattage bracket sits inside what your device can genuinely sustain, particularly on the lowest values, which ask for the most. That last point opens onto a wider question about how much power is really available on a given device, which we take apart in our reading of the [Aegis Solo 3 and its hundred watts](/uk/aegis-solo-3-power/). ## Life expectancy and the signs of wear A mesh strip in this family lasts on average one to two weeks, depending on how often you vape and what you put through it. British retailers commonly express the same thing as a number of refills rather than days. Low values worked hard wear faster than the high values kept for a tight draw. Three signs announce the replacement: a burnt taste that persists after a few draws, a clear drop in vapour volume at an unchanged setting, and gurgling that betrays a wick either saturated or badly fed. Waiting beyond those signals achieves nothing. A degraded mesh strip releases an acrid taste that masks the flavour profile of the liquid entirely, whatever its quality. Replacement is the only remedy, and no amount of rinsing brings a burnt strip back. ## Frequently asked questions ### Does a UB Max fit a standard Thelema? That depends on the version of the Thelema. The Thelema Centaurus takes UB Max, while the standard versions stay on the Ultra Boost V2. Checking the cartridge reference before buying remains the only reliable way to settle it. ### Can an Ultra Boost be fitted to an Ursa Mini? No, the two platforms do not share a connection. The Ursa Mini accepts UB Lite references only, whatever their resistance in ohms. ### Which value suits a tight draw? The high values in each family, such as the 1.0 ohm MTL in the Ultra Boost V2 or the L8 in 1.2 ohm in the UB Lite, correspond to that tight draw and to reduced power. ### Why do two packs of the same value carry different wattage brackets? The families use mesh strips of different construction, with heating surfaces that do not behave the same way. The resistance value alone is therefore never enough to compare two references. ### Can a new coil be tested without liquid? No, a mesh strip fired dry burns immediately. Always prime the part with a few drops of liquid and let it stand before the first use. ## Finding your way around the range Several families, several platforms, and one rule running through all of them: the name of the cartridge takes precedence over the name of the device. A well chosen set of **Lost Vape coils** always starts with that check, before anyone looks at a resistance in ohms. The same reading discipline applies to every modular product sold here, whatever the badge on the packaging. Our comparison of the [Voopoo PnP and PnP X platforms](/uk/voopoo-pnp-coils/) applies exactly this method to another ecosystem, as does our run through the [Geekvape series](/uk/geekvape-coils/), and the [coils section](/uk/category/coils/) gathers the rest.
