What Is a Sub-Ohm Vape Kit?

Sub-ohm kits are powerful vaping devices that can generate vast clouds of tasty vapour. Although they are slightly less popular than MTL refillable pod kits, they maintain a dedicated following who prefer the sensation of big cloud production over the moderate vapour and high nicotine strength ordinarily associated with MTL vaping.

Read on for a detailed and informative explanation of what precisely a sub-ohm vape kit is and how it operates.

What is a Sub-Ohm Vape Kit? 

“Sub-ohm” refers to the coils used in sub-ohm vape kits. Most vapes use coils with resistances of 1.0Ω and up; these coils require small power output from the vape battery and fight against the charge, resulting in moderate to large vapour production. This is also the reason why sub-ohm vapes are intended for direct-to-lung vaping. For further explanation of different vaping styles, check out our guide on MTL vs DTL vaping.

Compared to other vape types, sub-ohm vape kits use coils with much lower ohmage ratings, often between 0.15Ω – 0.6Ω. These low-resistance coils permit far more power to surge through them, producing a much more considerable amount of vapour. As such, sub-ohm vape kits will allow far greater power output, often in the range of 30W – 100W.

Aside from the huge wattage capacity and more vapour production, this vape type is equipped with multiple modes that are often geared toward experienced vapers.

Does Sub-Ohm Use More Battery?

Sub-ohm vaping uses more battery life due to the increased power output necessitated by sub-ohm coils. As a result, most sub-ohm kit vapes with integrated batteries will often have a capacity ranging between 1500mAh – 3000mAh.

Other sub-ohm advanced vape kits will require external batteries that charge within the mod casing, usually 18650 or 21700 batteries. This need for increased power often results in larger kits than MTL units, and they are usually a bit heavier and trickier to transport as well.

What Is the Best Wattage for a Sub-Ohm Vape?

Due to DTL vape devices’ much more comprehensive range of coil resistances, sub-ohm wattage varies far more than on MTL kits. For the average sub-ohm kit coil, the optimal variable wattage is often in the range of 30W – 55W, though, as mentioned, this varies. We recommend you always check the suggested wattage for any installed coil.

What is the Best Juice Ratio for Sub Ohm Vape Kits?

Sub-ohm kits and their coils require vape juice with a high VG ratio. The baseline VG / PG mix ratio for sub-ohm vape juice is 70 VG / 30 PG, and it’s not uncommon to find higher VG contents in many e-liquids intended for sub-ohm use.

Most (though not all) of the best shortfill e-liquids are intended for sub-ohm vaping. Be sure to check the VG / PG ratio on the product page before purchasing any shortfills for your sub-ohm kit.
