Lost Vape UB Mini Replacement Coils | 5 Mesh Builds
The coil platform behind Lost Vape's Ursa pod kits, the Orion Mini and the Thelema GO. Five mesh builds run from a 0.6Ω restricted direct-lung coil down to a 1.4Ω mouth-to-lung build. Sold singly or in a 5-pack.
Highlights
- Five mesh resistances: 0.6Ω, 0.8Ω, 1.0Ω, 1.2Ω and 1.4Ω
- S1 through S3 handle restricted direct-lung or mouth-to-lung; S4 and S5 are mouth-to-lung only
- Fits the Ursa series, Orion Mini, Thelema GO and UB Mini pod tanks
- Mesh throughout — faster ramp and cleaner flavor than a round wire coil
- Buy a single coil or a 5-pack
UB Mini coil specs
| Coil | Resistance | Wattage range | Draw |
|---|---|---|---|
| S3 | 0.6Ω | 16–21W | Restricted direct-lung or MTL |
| S1 | 0.8Ω | 12–17W | Restricted direct-lung or MTL |
| S2 | 1.0Ω | 9–13W | Restricted direct-lung or MTL |
| S4 | 1.2Ω | 9–11W | Mouth-to-lung only |
| S5 | 1.4Ω | Lowest power in the range | Mouth-to-lung only |
The S1 through S4 ranges above are Lost Vape's own published figures. Lost Vape does not list a wattage range for the S5 on its UB Mini page, so we are not going to invent one — it is the highest resistance here, so run it at or below where the S4 sits and let the device do the rest.
Which devices these fit
Lost Vape lists the UB Mini for the Ursa series pod kits — Ursa Nano, Ursa Nano Pro, Ursa Nano 3, Ursa Baby, Ursa Baby Pro and Ursa S — along with the Ursa empty cartridges, the Orion Mini, the Thelema GO, and UB Mini pod tanks.
Yes, the Thelema GO takes these. It is the one that catches people out, because the larger Thelema mods run the UB Pro coil instead. Same brand, same naming family, different deck — go by the pod in your hand, not the word Thelema on the box.
UB Mini also does not interchange with the UB Lite or the original Ultra Boost coils. Lost Vape runs several UB families side by side and they are not cross-compatible.
Picking a resistance
Work from your e-liquid. Nicotine salts belong on the S4 or S5 — both are mouth-to-lung only, both run cool and sip battery, and both give the tight cigarette-like draw that makes salts tolerable at high strength.
Regular freebase juice suits the S3 at 0.6Ω, the widest window in the lineup at 16–21W and the warmest, densest hit of the five. The S1 at 0.8Ω is the all-rounder most people settle on: enough power to taste, tight enough to stay discreet, and it does not drain a small pod battery by lunchtime.
Getting a full life out of a coil
Install the coil, fill the pod, then wait five to ten minutes before your first puff so the mesh saturates. Start at the low end of the printed wattage for the first tank. The two fastest ways to kill a UB Mini coil are chain-vaping a nearly empty pod and pushing a high-resistance coil past its range.
One to two weeks is typical. Swap it when the flavor goes flat or you taste a burnt edge that a refill does not fix.
Why buy UB Mini coils from Central Vapors
We stock all five builds, including the S5 that most shops skip, and we sell singles as well as 5-packs so you can find your resistance without committing to five of the wrong one. Central Vapors has been filling vape orders since 2013, and every order is backed by our satisfaction guarantee.
UB Mini coils — common questions
| Q |
Which devices do UB Mini coils fit? The Ursa series pod kits — Ursa Nano, Nano Pro, Nano 3, Ursa Baby, Baby Pro and Ursa S — plus the Ursa empty cartridges, the Orion Mini, the Thelema GO and UB Mini pod tanks. |
| Q |
Does the Thelema GO use these or UB Pro coils? The Thelema GO uses UB Mini — Lost Vape lists it on the coil's own spec sheet. The bigger Thelema mods are the ones that take UB Pro coils. |
| Q |
Is UB Mini the same as UB Lite or Ultra Boost? No. Lost Vape runs several UB coil families for different decks. UB Mini does not interchange with UB Lite or the original Ultra Boost. |
| Q |
Are the S4 and S5 mouth-to-lung only? Yes. Lost Vape labels both as MTL only. The S1, S2 and S3 are rated for either a restricted direct-lung or a mouth-to-lung draw. |
| Q |
Which coil gives the warmest, densest hit? The S3 at 0.6Ω. It is the lowest resistance in the range and runs the widest window, up to 21W. |
| Q |
How often should I replace one? One to two weeks is typical. Prime each new coil, wait five to ten minutes after the first fill, and swap when flavor goes muted or burnt in a way a refill does not fix. |
For use by adults 21+.
