Pod Cartridge show 0.4Ω，0.6Ω，0.8Ω or 1.2Ω，how to choose

Those numbers represent the resistance of the heating coil inside the pod, measured in Ohms ( $\Omega$ ).

As a general rule of thumb: Lower resistance means more heat, more vapor, and a looser draw. Higher resistance means less vapor, a tighter draw, and a feel that closely mimics a traditional cigarette.

Here is a breakdown to help you choose the right pod for your vaping style:

Resistance Quick-Reference Guide

Pod Resistance	Vapor Production	Airflow / Draw	Best Liquid Type	Best For
0.4 $\Omega$	High	Very Loose (Direct-to-Lung)	Freebase (Low Nicotine: 3mg – 6mg)	Big clouds, intense flavor
0.6 $\Omega$	Medium-High	Loose (RDL / Loose MTL)	Freebase or Low Nic Salt	A balance of clouds and throat hit
0.8 $\Omega$	Medium	Medium-Tight (MTL)	Nicotine Salts (20mg)	Most popular “all-rounder” for flavor
1.2 $\Omega$	Low	Tight (Strict MTL)	Nicotine Salts (20mg)	Maximum battery saving, cigarette-like feel

Detailed Breakdown

1. The High-Resistance Options (1.2 $\Omega$ or 0.8 $\Omega$ )

These are designed for Mouth-to-Lung (MTL) vaping, which is the same way you would smoke a cigarette (pulling vapor into your mouth first, then inhaling it into your lungs).

1.2 $\Omega$ Pods: These deliver a tight, restricted draw and discreet vapor production. They are highly efficient, making your battery and e-liquid last longer.
0.8 $\Omega$ Pods: This is the sweet spot for many beginners. It provides a slightly warmer vape and better flavor clarity than the 1.2 $\Omega$ pod, while still working perfectly with high-strength nicotine.
Best E-Liquid Pairings: Nicotine Salts (typically 12mg to 20mg in Canada/Health Canada regulated markets). The lower power stops you from getting too much nicotine at once.

2. The Low-Resistance Options (0.6 $\Omega$ or 0.4 $\Omega$ )

These require more wattage from your device and are meant for Restricted Direct Lung (RDL) or Direct Lung (DL) vaping, where you inhale the vapor directly into your lungs like taking a deep breath.

0.6 $\Omega$ Pods: A hybrid style. It gives a warm, robust hit with significantly more vapor. It can be used for a very loose MTL draw or a restricted lung hit.
0.4 $\Omega$ Pods: This maximizes the power output of your device. It creates large clouds and intense flavor but will drain your battery and consume e-liquid much faster.
Best E-Liquid Pairings: Freebase Nicotine (3mg or 6mg) or very low-strength nic salts. Avoid using high-strength (20mg) nicotine salts with a 0.4 $\Omega$ pod, as the vapor volume will make the throat hit incredibly harsh and deliver too much nicotine at once.

Which one should you pick?

If you are switching from cigarettes and using Nicotine Salts, start with the 0.8 $\Omega$ or 1.2 $\Omega$ pod.
If you want bigger clouds, a looser draw, and lower nicotine, go with the 0.6 $\Omega$ or 0.4 $\Omega$ pod.

Most starter kits include two different pods in the box (usually a 0.6 $\Omega$ and an 0.8 $\Omega$ or 1.0 $\Omega$ ). It is highly recommended to try both with your chosen e-liquid to see which style feels more comfortable to you!
