Weak Hit – What It Means in Vaping & How to Fix It

Definition

A “Weak Hit” is a vape draw that produces noticeably less flavour, warmth, or visible vapour than expected. For Australian vapers, it’s the frustrating moment when your device fires but the experience feels flat—almost like inhaling flavoured air instead of a satisfying cloud. Technically, a weak hit signals that the coil is not vaporising e-liquid efficiently, robbing you of the nicotine, taste and throat hit you’re chasing. Recognising a weak hit early helps prevent dry coils and wasted juice.

Technical Details

Inside your tank or pod, a weak hit occurs when electrical energy, wicking speed and airflow fall out of balance. The coil’s Wire (usually Kanthal, Ni80 or SS) needs adequate Wattage to reach its ideal temperature; if the mod is set too low, the coil cannot fully vaporise the juice soaked into the Wick. Conversely, if the Wicking Material is packed too tightly or the cotton is old, e-liquid cannot travel fast enough to the coil, causing the cotton to overheat and produce a thin vapour. Coil geometry also matters: fewer Wrap (Coil Wraps) reduce surface area, so the same wattage may feel weaker than with a multi-wrap build. Standard sub-ohm tanks are optimised around 0.15–0.5 Ω coils and 40–80 W; dropping below that range without adjusting airflow or nicotine strength is the most common trigger for weak hits in Australia.

Usage & Tips

  • Check Wattage Range: Match your mod’s output to the coil’s printed range (e.g., 0.2 Ω mesh rated 50–60 W). Start low and increase in 5 W increments until flavour returns.
  • Re-wick or Replace: A dark, crusty wick blocks juice flow. Swap the cotton or install a new coil every 5–10 days of heavy use.
  • Prime Thoroughly:Drip e-liquid directly onto the wick and take a few dry pulls (without firing) before first use to prevent dry spots.
  • Thin High-VG Juices: In colder Australian winters, 70 VG/30 PG liquids can thicken; try 60/40 or gently warm the pod between your hands.
  • Safety First: Resist cranking the wattage beyond the coil’s limit—this can burn cotton or stress batteries, leading to leaks or venting.

History & Context

Weak hits became a hot topic around 2016 when high-wattage box mods and low-resistance mesh coils hit the mainstream. As Aussie vapers chased bigger clouds, manufacturers responded with “best-wattage” bands printed on coils and smart-chip mods that auto-suggest wattage. Today, understanding weak hits is part of everyday coil maintenance and helps users comply with Australia’s nicotine prescription laws by ensuring consistent nicotine delivery without overconsumption.
