Choosing freebase liquid certainly provides a unique satisfaction, especially for those who are after thick clouds and a distinctive throat hit sensation. However, no matter how good a liquid is, its potential won't be unleashed if you choose the wrong coil size.

Many vapers, especially those who are new to switching from small pod devices or salt nic liquids, often struggle to determine the correct resistance (Ohm). If you just put it in arbitrarily, be prepared for a bland taste or a coil that burns out instantly on the first puff.

To maximize your device's performance and get a "kick" out of the flavor, let's look at the complete guide below!

What Ohm for Freebase Coils?

If you're asking what the ideal Ohm is for a freebase coil, the absolute answer is: use a Sub-Ohm coil, which is below 0.6 Ohm.

Why shouldn't you use a coil with a high Ohm (such as 1.0 Ohm or 1.2 Ohm)? The reason lies in the texture of the liquid itself. Freebase liquids generally have a high VG (Vegetable Glycerin) ratio, typically around 70/30 or 80/20. This makes the liquid's texture very thick.

Thick liquid requires a high heating temperature to boil and vaporize perfectly. This high temperature can only be achieved with high power (wattage). Electrically, high power must be paired with a low resistance coil (below 0.6 Ohm).

If you insist on using a 1.0 Ohm coil for freebase, the cotton won't have time to absorb the thick liquid quickly. The coil will immediately experience a dry hit (burnt), the taste becomes bland, and vapor often splashes into the mouth (spitback).

Freebase Coil Sizes

To avoid confusion when buying replacement coils or cartridges, here are the details of the most common freebase coil sizes and their effects:

• 0.15 Ohm – 0.2 Ohm (Cloud Chaser Mode) This size is the "natural habitat" of users of high-powered MODs or AIOs. These coils usually require high power, ranging from 50W to 80W+. Characteristics: The vapor produced is very thick, warm, and the flavor feels very bold. Very suitable for freebase liquid with a VG ratio of 70/30 or 80/20.

• 0.3 Ohm – 0.4 Ohm (Sweet Spot) This is the most balanced size and is often used by mid-range Pod Mod or AIO users. Operating in the power range of 25W to 45W, this coil provides a good compromise. Characteristics: The vapor is quite thick, the taste is very detailed, but it doesn't drain the battery too much and doesn't make the device heat up quickly.

• 0.6 Ohm (Maximum Limit for Freebase) 0.6 Ohm is the "boundary line". This coil is still safe for freebase liquid, but it's best to choose a freebase with a VG/PG ratio of 60/40 or a maximum of 70/30, which is not too thick. The power usually plays around 15W to 25W. Characteristics: The draw is smoother, the vapor is not too excessive, and it's very battery-efficient.

Conclusion

The main key to an enjoyable vaping experience is the adjustment (matching) between the liquid's viscosity and the coil's size. For freebase liquid, always remember this formula: the thicker the liquid, the smaller the Ohm value you need.

Make sure you always check the power range (Best Wattage) which is usually written on the coil's body so that your heating wire works at its most optimal temperature!
