Common Questions
| Q | Is the UB Mini the same as the UB Lite or original Ultra Boost? No. Lost Vape makes several UB coil families for different devices - the UB Mini fits the Ursa Nano and Ursa Baby series plus the Thelema Go, and doesn't interchange with the UB Lite or the original Ultra Boost coils. |
| Q | Which UB Mini coil is best for a warmer, denser hit? The S3 at 0.6ohm is the lowest-resistance build in the lineup and runs the widest wattage window, up to 21W. |
| Q | Are the S4 and S5 coils only for MTL? Yes, both are labeled MTL-only by Lost Vape, unlike the S1-S3 builds which handle a DRL (direct-to-lung-restricted) or MTL draw. |
| Q | Will these fit my Ursa Nano Pro? Yes, Lost Vape carries the same UB Mini coil deck across the Ursa Nano, Nano Pro, Nano 3, and the Ursa Baby series. |
For use by adults 21+.
UB Mini Coils — Common Questions
The UB Mini platform fits the Lost Vape Ursa Nano, Ursa Baby, and Ursa Mini family. If you have a Quest or Thelema, those take the larger UB Pro series instead — double-check your device before ordering.
Lower-ohm UB Mini coils give warmer vapor and more cloud at higher wattage; the 1.0Ω-plus options give a cooler, tighter draw at low wattage that suits nicotine salts. The resistance table above lists everything we stock.
Prime it: install the coil, fill the pod, and wait five to ten minutes so the cotton saturates before your first puff. Chain-vaping dry or running max wattage on a high-ohm coil are the two fastest ways to burn one out early.
One to two weeks is typical. Swap it when flavor goes muted or you taste a burnt edge that priming and a refill don't fix.
