Ultra Boost (UB) Replacement Coils by Lost Vape produce good vapour flavour and have enough variety in wattage and resistance of coils, to cover direct-lung (DL) and mouth-to-lung (MTL, cigarette-style draw) vaping and also includes a rebuildable atomiser (RBA) for the vaping gurus.

Lost Vape UB Coils, also known as UB Ultra Coils or Ultra Boost Coils, are made for enjoying prominent vape clouds and vapour flavour which varies depending on which coil you choose.

UB Coils are compatible with the following Lost Vape kits and tanks:

DL and MTL vaping options

Lost Vape UB Coils have variety to suit all types of vaping styles, such as:

  • MTL vaping: a cigarette-style puff, where you draw and hold vapour in your mouth before inhaling to your lungs.
    • Use UB MTL Coil which has high-resistance (1.0 ohm) and low-wattage (8-15W) to get cool vapour, good vapour flavour and a more restricted draw.
  • DL vaping: an airy puff where you draw vapour straight to your lungs, like taking a deep breath in through your drip tip/mouthpiece.
    • Use M1, M2, M3 or M4 UB Coil for a boost in vapour flavour and larger vape clouds. The higher the wattage and the lower the resistance means even warmer vapour, better vapour flavour and bigger vape clouds than higher resistance and lower wattage.
  • Build your own coil: for advanced vapers only using the UB RBA Deck.

Please note:

  • UB Replacement Coils are not compatible with the Ursa Pro Replacement Pod that also features in the Ursa Quest Multi Kit.
  • It's important you prime new coils to avoid burning or dry hits. To do so, saturate the coil's cotton by placing e-liquid in the coil centre before installation. Once installed, fill the tank and wait about five minutes before vaping. See our 'How to prime new coils' frequently asked question for more information.
