Vaping enthusiasts in the UK are always on the lookout for coils that last longer, deliver better flavour, and enhance the overall experience. Two popular options—Vaporesso GTX Coils and Innokin Z Coils—are sold by the trusted Vape Online Store, and they continue to dominate the market for a reason. But when it comes to durability, which one truly holds up better over time?
In this comparison, we’ll break down how these two coil lines perform, how long they typically last, and which may offer better value for your device and vaping style.
Why Coil Durability Matters
A vape coil’s lifespan affects both your wallet and your vaping enjoyment. A durable coil means fewer replacements, consistent flavour, and reliable vapor production. When coils burn out quickly, they not only affect the taste but can also ruin your e-liquid and device performance.
That’s why choosing between Vaporesso GTX Coils and Innokin Z Coils is about more than just compatibility—it’s about investing in long-lasting quality.
Understanding Vaporesso GTX Coils
Vaporesso GTX Coils are part of the high-performance range that supports both restricted direct lung (RDL) and mouth-to-lung (MTL) vaping. They’re made using mesh technology, which ensures faster heating and better e-liquid absorption. The result? Dense vapor, intense flavour, and a smooth draw.
GTX Coils are available in a variety of resistances, including:
0.2Ω and 0.3Ω for sub-ohm vaping
0.6Ω to 1.2Ω for MTL and low-wattage use
In terms of durability, GTX Coils typically last 5–10 days with moderate use, though some users report up to two weeks with optimal settings and proper care.
Innokin Z Coils: Built for Longevity
Innokin Z Coils, formerly known as Zenith Coils, are widely appreciated for their solid construction and coil life. They’re made specifically for MTL vaping, ideal for those who prefer a tighter draw and higher nicotine e-liquids, including nic salts.
Z Coils use Kanthal wire with organic cotton and offer multiple resistance levels:
0.3Ω for warm, loose MTL hits
0.8Ω and 1.2Ω for cooler, tighter MTL
1.6Ω for minimal vapor and maximum throat hit
Z Coils are known to last up to 14 days or more, making them a top choice for vapers who want longer-lasting coils with fewer changes.
Coil Lifespan Comparison
Let’s break it down:
Vaporesso GTX Coils
Average lifespan: 7–10 days
Mesh coil structure enhances flavour
High VG e-liquids may wear them out faster
Best with moderate to heavy use
Innokin Z Coils
Average lifespan: 10–14 days
Traditional round wire offers slower degradation
Excellent with 50/50 e-liquids and nic salts
Ideal for consistent, low-wattage users
If you’re looking for maximum coil life, Innokin Z Coils edge out slightly, especially for MTL vapers. But GTX Coils aren’t far behind, especially if you enjoy larger clouds and a quicker heating response.
Device Compatibility and Usage
GTX Coils are used with devices like:
Vaporesso Target PM80
Vaporesso Luxe PM40
Vaporesso Xiron
They support both sub-ohm and MTL styles, giving you flexibility.
Z Coils are compatible with:
Innokin Zenith
Innokin Zlide
Innokin Coolfire Z Series kits
These are geared more toward consistent MTL experiences, great for ex-smokers and nic salt fans.
When used in the right wattage range and with suitable e-liquids, both coil types offer satisfying performance. However, Innokin Z Coils shine for users who want consistent low-wattage vaping without needing frequent coil replacements.
Tips to Extend Coil Life
Whichever coil you choose, follow these practices to increase longevity:
Prime the coil before first use (add drops of e-liquid directly to the cotton)
Let the coil sit for 5–10 minutes before vaping
Use the recommended wattage range
Avoid dry hits and chain vaping
Use cleaner, thinner e-liquids for MTL coils
Final Thoughts
So, which coil is more durable—Vaporesso GTX Coils or Innokin Z Coils?
If you value versatility and powerful vapor production, GTX Coils are impressive with decent longevity for sub-ohm vaping. But if your priority is durability, Innokin Z Coils take the lead. With careful usage, they can easily last over two weeks, offering excellent value and performance for MTL users.
Both are excellent products available from the Vape Online Store, a reliable UK retailer offering authentic coils, fast delivery, and excellent support. Whether you're chasing clouds or enjoying calm MTL puffs, one of these coil options will meet your expectations for durability and performance.
