Buying the wrong coil is easy to do, because Vaporesso makes several coil families and none of them are interchangeable. This guide explains which coil fits which tank, what the resistance numbers mean and when to replace one. You can see the full range of Vaporesso coils alongside the kits they fit.
Short answer: GTX coils fit the Armour G and Luxe XR Max 2. GTi coils fit the iTank T on the Armour Ultra and Armour S, and the iTank and Target kits. Pick the coil family for your tank first, then choose the resistance for your inhale style.
What are Vaporesso coils?
A coil is the heating element that turns e-liquid into vapour. On most small pod kits the coil is built into the pod, so you swap the whole pod. On bigger kits such as the Armour range, the coil is a separate part that screws or pushes into the tank, so you replace the coil on its own.
Vaporesso replacement coils come in three families. GTX and GTi are the mesh coil families for current kits. GT coils are for older NRG, Cascade and SKRR tanks. Each family only fits the tanks it was made for.
Vaporesso GTX coils: resistances and what they fit
Vaporesso GTX coils come in packs of 5. The pack lists six mesh resistances, each with a recommended power and vaping style.
| Resistance | Vaping style | Recommended power |
| 0.2Ω | Direct-lung | 55W |
| 0.3Ω | Direct-lung | 40W |
| 0.4Ω | Restricted direct-lung | 30W |
| 0.6Ω | Restricted direct-lung | 24W |
| 0.8Ω | Mouth-to-lung | 16W |
| 1.2Ω | Mouth-to-lung | 11W |
Use high-VG e-liquid, 60% VG or more, with the direct-lung coils. Use e-liquid with 50% PG or more with the mouth-to-lung coils.
GTX coils fit the Armour G and the Luxe XR Max 2. They also fit older kits, including the Luxe 80, GTX One, Gen Nano, Swag PX80 and Target PM80.
Vaporesso GTi coils: resistances and what they fit
Vaporesso GTi coils also come in packs of 5. They are built for high-power direct-lung vaping, with organic cotton wicks and mesh construction.
| Resistance | Recommended power |
| 0.15Ω | 75W to 90W |
| 0.2Ω | 60W to 75W |
| 0.4Ω | 50W to 60W |
| 0.5Ω | 30W to 40W (35W is the stated best) |
GTi coils fit the iTank and iTank 2, plus the Target series, including the Target 80, 100 and 200. They also fit the iTank T that comes with the Armour Ultra and Armour S.
Vaporesso Armour Ultra and Armour S: which coil to use
The Vaporesso Armour Ultra has a 5500mAh battery and runs from 5W to 100W. It comes with an iTank T and uses GTi dual mesh coils. A GTi 0.2Ω coil comes fitted and a 0.4Ω coil is included as a spare.
- GTi 0.2Ω (60W to 75W): more flavour and more vapour.
- GTi 0.4Ω (50W to 60W): a more restrained hit and a longer coil life.
The Vaporesso Armour S is a single-battery kit that also runs from 5W to 100W. It takes an 18650 or 21700 battery, sold separately, and uses the same iTank T and GTi coils, with a 0.2 and a 0.4 mesh coil in the box. It is a smaller alternative for direct-lung vapers who do not want a bulky device. The Armour S kit is currently sold out at the retailer, so check availability before you plan around it.
The Armour G is different. It has a 3000mAh battery and runs from 5W to 80W, but it uses GTX coils, not GTi. Do not mix the two families.
How to choose Vaporesso replacement coils
1. Find your tank or kit name
Look for the name on your device, such as Armour Ultra, Armour S, Armour G, iTank or Target. The name tells you the coil family. For example, an Armour Ultra needs GTi and an Armour G needs GTX.
2. Choose the resistance for your inhale style
Lower resistance suits higher power and more vapour, which is direct-lung vaping. Higher resistance suits lower power and a tighter draw, which is mouth-to-lung. Match the resistance to the power range your device can deliver.
3. Match the e-liquid
Low-resistance coils suit high-VG e-liquid, and high-resistance coils suit e-liquid with 50% PG or more. UK nicotine e-liquid is capped at 20mg/ml and sold in bottles of 10ml or less. Nicotine is addictive, so choose the lowest strength that works for you.
When should you replace a Vaporesso coil?
A Vaporesso coil can last up to four weeks, depending on how much you vape and which e-liquid you use. Sweet e-liquids and high power wear a coil out faster. As a rule, replace the coil when the flavour goes flat or burnt, the vapour gets thin, or the tank starts to gurgle or leak.
Prime every new coil before you use it. Soak the coil in e-liquid, fill the tank, wait a few minutes, and take breaks between sessions so the cotton stays saturated. Dry hits can shorten a coil’s life.
Frequently asked questions
Do GTX coils fit the Armour Ultra?
No. The Armour Ultra uses GTi coils in its iTank T. GTX coils fit the Armour G and Luxe XR Max 2.
Which coil should I use in the Armour Ultra?
Use the GTi 0.2Ω for the most flavour and vapour, and the GTi 0.4Ω for a more restrained hit and longer coil life.
Can I use GTi coils in the Armour S?
Yes. The Armour S kit uses the iTank T and takes all Vaporesso GTi coils.
Are Vaporesso coils the same as Vaporesso pods?
No. Pods have the coil built in and you replace the whole pod. Coils are separate parts for bigger tanks and kits. Check which one your device uses.
Final thoughts
Choosing the right Vaporesso coils comes down to three things: the coil family for your tank, the resistance for your inhale style and the e-liquid you use. Check the name on your device first and you will avoid most mistakes. If you want advice before you buy, the team at greyhaze offers live chat and in-store help in Birmingham.
