Vaporesso iTank, getting to grips with your first sub-ohm tank
After a few months on a pod, plenty of vapers end up with a Vaporesso iTank without quite knowing what comes next. Shop listings line up ohms, watts and millilitres, but rarely say who the kit is actually for. Why is there a spare glass, how do you fill it without a leak, what wattage should the mod show? One wrong setting on the first evening is enough to burn a brand new coil.
Vaporesso iTank, the direct answer
The Vaporesso iTank is a sub-ohm tank, meaning a tank whose coil sits below one ohm, designed for direct lung vaping. It screws onto a mod with a 510 connection, fills from the top and runs on Vaporesso’s GTi coils, at anywhere between 30 and 90 W depending on the coil fitted.
Two models share the name. The iTank 2, which Vaporesso describes as the upgraded version of the original iTank, opens with a press on its lid. The newer iTank T moves its airflow to the top and fills by sliding the top cap across.
This is not a first-day device. Even the lowest-powered coil in the GTi range needs 30 W, set on a separate mod. The Vaporesso iTank is therefore for someone who already owns an adjustable mod and wants a bigger, airier draw.
The words to know before unboxing
Three terms appear on every listing. Knowing them before you open the box heads off most first-week mistakes.
Sub-ohm and direct lung vaping
A sub-ohm coil has a resistance below 1 ohm. The lower the figure, the more power the mod has to send to heat it. Direct lung vaping, often shortened to DL, means inhaling the vapour in one breath, without holding it in the mouth first as you would with a mouth-to-lung pod.
GTi coils
The coil is the part that heats the liquid. In this tank it is a removable metal head from the GTi series, holding a mesh heating element and cotton.
The 510 connection and the 810 drip tip
The 510 connection is the standard thread that joins the tank to the mod. An 810 drip tip is the wide mouthpiece, and it is the format two retailers list for the iTank T.
Which Vaporesso iTank do you have
Identify the model before anything else, because the filling steps differ. The name is printed on the box, and a couple of visible details settle it otherwise.
| Detail | iTank 2 | iTank T |
|---|---|---|
| Opening for filling | lid that opens with a press | top cap that slides across |
| Airflow | not stated on the manufacturer page | at the top, set with a ring |
| Capacities listed by Vaporesso | 8 ml, 5 ml, 2 ml (TPD) | 6 ml, 3 ml, 2 ml (TPD) |
| Coils | GTi series | GTi series |
Capacity is the line to read twice. In the UK, a refillable tank is limited to 2 ml, and nicotine e-liquid is sold in bottles of no more than 10 ml at up to 20 mg/ml. Vaporesso lists a 2 ml TPD version of both the iTank 2 and the iTank T, even though its official store only sells the iTank T in 6 ml. A UK retailer describes the iTank T it sells as UK TPD compliant, so check the capacity printed on your own packaging rather than trusting an overseas listing.
Filling and priming the iTank T
The first fill decides the fate of the first coil. The movement itself is simple, but the wait that follows matters as much as the filling.
Top filling, step by step
Slide the top cap across to uncover the filling port. Push the thin nozzle of the bottle into the port and pour slowly, stopping short of the top of the glass. Then slide the cap back until it stops.
The iTank 2 follows the same idea, except that the lid lifts with a press instead of sliding.
Why you wait before the first draw
A new coil holds dry cotton. Before fitting it, drip a few drops of liquid onto that cotton, then let the filled tank stand for a few minutes. The pause gives the wick time to soak through. Firing a coil while the cotton is still dry leaves a burnt taste that never goes away.
Picking a GTi coil and setting the wattage
The box holds two coils, a 0.2 ohm fitted in the tank and a spare 0.4 ohm. Vaporesso states that the iTank T works with the whole GTi series, and publishes a power range for each coil.
| GTi Mesh coil | Range stated by Vaporesso | Suggested setting |
|---|---|---|
| 0.15 ohm | 75 to 90 W | 85 W |
| 0.2 ohm (fitted) | 60 to 75 W | 65 W |
| 0.4 ohm (in the box) | 50 to 60 W | 55 W |
| 0.5 ohm (sold separately) | 30 to 40 W | 35 W |
For a first session, the spare 0.4 ohm is a gentler starting point than the 0.2 ohm fitted at the factory. Set the mod at the bottom of the range, then raise it a few watts at a time from one session to the next. That stepwise method is laid out in our guide to vape wattage settings.
One retailer review claims the tank only takes GTi coils from 0.15 to 0.3 ohm. The manufacturer’s own page, which puts a 0.4 ohm in the box, settles the point.
Changing the coil without a leak
A GTi coil does not screw in. It pushes into the base of the tank, and it is the base that unscrews. Two retailers describe the same sequence.
Empty the tank first. Unscrew the base, pull the old coil out, then push in the new one after wetting it with a few drops. Screw the base back on, refill, and allow the same waiting time as on day one.
A seal that has slipped out of place can be enough to cause a leak after this job. Check that each O-ring sits in its groove before screwing the base back, and note that the box includes spares.
Setting the airflow on the Vaporesso iTank
The airflow sets how much air mixes with the vapour. On the iTank T it sits at the top of the tank and adjusts with a ring that uncovers more or less of the slots.
With the ring wide open, the draw is very airy. Close it down and the draw tightens while the flavour concentrates. Start halfway, then move one notch at a time. Changing wattage, airflow and coil all at once makes it impossible to tell which change helped or spoiled the result.
On both the iTank 2 and the iTank T, Vaporesso also describes a system that returns condensation towards the coil so it can be vaporised again. The manufacturer presents it as a way to limit leaks from the bottom, which is no excuse for leaving the top cap loose after a refill.
FAQ
These questions come up with a first sub-ohm tank, and the product listings leave them unanswered.
What is the difference between a rebuildable atomiser and a tank like this?
A tank of this kind takes ready-made coils that you swap without tools. A rebuildable atomiser asks you to fit the wire and cotton yourself. The iTank belongs to the first group, so it needs no particular skill.
Which tank suits a mod limited to 40 W?
With an iTank, only the 0.5 ohm GTi coil stays inside its stated range at 40 W. The other three need at least 50 W, so check your mod’s ceiling before buying spare coils.
How do I remove a coil that will not come out?
On the iTank, the coil does not unscrew, it pulls out. If it sticks to the base, grip it with a piece of kitchen paper for more hold and pull straight along its axis, without twisting it sideways.
When should the coil be replaced?
Vaporesso does not say how long a GTi coil should last. Four signs usually point to a worn coil, namely a burnt taste, fading flavour, weaker vapour and liquid that darkens quickly in the glass.
Can I use an iTank for mouth-to-lung vaping?
Closing the ring tightens the draw, but the tank is still built for direct lung vaping with sub-ohm coils. For mouth-to-lung, a pod is the better fit, as our guide on how to use a pod vape explains.
Vaporesso iTank, the right settings to start with
The Vaporesso iTank comes down to four steps, namely identifying your model, filling short of the top, letting the cotton soak and starting at the bottom of the power range. The spare 0.4 ohm coil and the airflow ring set halfway make a sensible starting point.
That leaves the capacity, to be checked on the box against the UK 2 ml limit. A Vaporesso iTank set up properly on the first evening shows a rule that holds for any tank, whatever the brand, one change at a time.
