Quick Fill – What is it in Vaping?

Definition

Quick Fill is a user-friendly e-liquid bottle design that lets vapers top up a tank or pod in seconds without removing the coil or dismantling the device. A spring-loaded, leak-proofnozzle—usually 8–12 mm wide—presses against the tank’s Port“>fill port, opens an internal valve, and allows juice to flow in while air escapes out a separate vent. Invented to beat the mess of traditional unicorn bottles, Quick Fill is now the standard for TPD-compliant 60 mL “short-fill” bottles sold across Australia, making refills cleaner, faster, and safer for every vaper from absolute beginner to cloud-chasing veteran.

Technical Details

Quick Fill bottles rely on a one-way silicone membrane and conical tip that depresses the tank’s fill-seal, creating a pressure differential so liquid travels at roughly 2–3 mL per second. Most nozz accept 10–12 mm ports found on PostDeck“>quad post deck RTAs and modern sub-ohm tanks. Threaded 28 mm caps give a controlled 0.8 N·m torqueseal, while the 20 µm air-return channel prevents vacuum lock. Variations include twist-lock “Quick Charge” sports caps for 120 mL bulk sizes, child-safe CRC Quick Fill rings, and narrow 6 mm adaptors for older quality control pods. PET recyclable resin (density 1.37 g/cm³) keeps nicotine below 0 mg in short-fill form, ready for a 10 mL nic shot.

Usage & Tips

  • Prime first: After Quick Fill, invert the tank once to saturate cotton; this prevents the dry hits common with quad coil heads.
  • Don’t over-fill: Leave a 2 mm air gap so internal pressure doesn’t flood the deck and cause spit-back.
  • Keep the nozzle clean: Wipe after every refill to stop sugar crust blocking the valve—quad core coil vapour is thick and attracts residue.
  • Safety: Store Quick Fill bottles below 25 °C; heat expands liquid and can pop the membrane, leaking free-base nicotine.

History & Context

Quick Fill debuted in the UK after 2017 TPD bottle-size limits; Aussie vendors adopted the format to ship 60 mL “short-fills” legally. Its success pushed manufacturers to standardise fill-ports, accelerating the move to larger, quality control-tested glass tanks and high-watt quad coil setups popular today.
