Innokin Prism Replacement Coils (T18e, T22e)

By Warles Chinsor from Buckingham Palace

What I've learned so far... (16 April 2025)

I bought an Innokin Endura T22 pro kit recently. It came with the 1.7 ohm coil fitted and a spare 1.5 coil in the box.

I destroyed the fitted coil immediately by following the instructions - it says to press the button 3 times to turn on the vape after turning it on underneath. That wasn't actually necessary, so those 3 quick presses burnt out the coil in the empty tank

I changed to the 1.5 coil immediately. The 1.5s seem to be relatively decent coils, with a big hit of nicotine and a decent flavour. I had no issues with that coil. It lasted almost a fortnight before the first burnt taste appeared, which is superb. Flavour did drop off a bit towards the end of that time but no worse than any other coils.

The 1.5 coil doesn't have a plastic seal around the bottom of the connector bit that screws onto the vape, and the air holes are mounted low, so it leaked a bit into the battery connector recess on my vape. No biggie, a bit of scrunched up kitchen towel sorts it in seconds and you only have to do that maybe every other day. My old Totally Wicked (Arc 2?) vape leaked and flooded much worse, so I'm an expert with torn up bits of kitchen roll!

I changed to a 1.7 coil after that. The first one tasted incredibly burnt immediately. I assumed it was a dodgy coil, changed it for a new one, waited a good half hour for it to prime, and again got the nasty burned taste immediately. I got confused at that point. I guessed that maybe I'd accidentally put the burnt coil back into the vape, rather than the fresh one?

I emptied the tank again, and opened another coil. I left it an hour before hitting it this time.

The first few hits were divine. Bags and bags of flavour, the most I've ever had from a big boy vape. Then the burnt taste came again after just a few puffs. Then promptly disappeared.

I've never had a taste that bad on any coil that then goes back to tasting sweet and delicious and working fine, but that's what happened. Repeatedly. It tastes like it's surely knackered, then reverts to working perfectly.

I reasoned that it couldn't be the wire burning out, it had to be a dry spot on the cotton wicking. I soon realised that bubbles were causing that. The holes in the coil somehow create bubbles in the liquid. The bubbles result in a dry patch of wick. As soon as you tap the vape to release the bubble into the tank, the coil will work perfectly again, and taste good again, until the next bubbles form from you puffing on it.

I've fought with it for the last three or four days, tapping bubbles out before every hit. l turned down my vape to 11w which helped prevent the bubbles. I stopped sucking so hard when having a puff, which also helped. I'm using 40/60 liquid ATM, it seems to prefer it to 50/50.

That combination of tactics has now worked successfully for the last 48 hours in a coil I was going to throw immediately.

I've just bought a box of 1.7s and a box of 1.5s. The 1.7s are clearly vastly superior in terms of flavour, but if they're all as much hassle as this one has been, I'll stick to the 1.5s for an easy life, thanks.

An extra bonus is, they're comparatively cheap. £1.40 for a coil that lasts a fortnight is great. It doesn't make up for the bottle of liquid and 3 coils wasted changing them 3 times in one day, but I'm living and learning.

I dunno whether it's allowed but if it is, I'll post my findings again after going through these boxes of coils.

TDLR: It's air bubbles, bang your vape a few times.

Good Coils (04 December 2024)

I've been using these coils since I started vaping and I find them pretty decent compared to some of the others.

By David from Uk

Getting better? (27 June 2024)

These have been a little unreliable until recently. I realised that sometimes when you first use them they can appear faulty, but if you leave them for an extended period of time after adding the fluid they start working. I don't know how many coils I've thrown away assuming they were dead on arrival. In my most recent order the coils were individually wrapped in paper (instead of plastic) maybe they're better quality now?

By Ross from Bristol

reliable (14 May 2024)

not sure why many people say they get unlucky ones - I've used over 100 of these and never once had one that didnt last a in my opinion "full" 5 refills or full 10ml bottle of juice. sometimes I'll get about 7-8 refills before the flavour starts to die off.

Not as good flavour as some coils but these are good and reliable and much cheaper than most coils which i find for other devices is usually closer to £10 for 5. I find throat hit is quite mild unless I have a strong juice.

Used in endura t18ii for years.

I've not tried the pro versions yet.

Yep (12 May 2024)

Exactly what you need if you have a T18E. Replacing them can be a little leaky, due to the chamber construction, but they do what they're supposed to. Make sure to give them a good soak before firing, of course.

By TheDreamer from Sheffield

Decent (29 April 2024)

These seem decent, but I don't have much to compare to with these as it seems the only option for the T18E as far as I can see. I would say they seem quite easy to flood. I have so far only tried 2 types of Innokin vapes, and a Smok (which I didnt like as it wasn't very good for MTL), so bear in mind my experience is still pretty limited.

By Fae from N.Yorks

Ok (26 March 2024)

To be honest I have nothing to compare these too as I’ve only used innokin products, but so far they have been ok
The only issue is they do flood quite easily, which can be alarming when you here the pops and gurgles whilst vaping, but overall I have been happy with how easy to use and how long they are lasting so far

By Mands from Northamptonshire

Bad (11 December 2023)

I'm not sure what has happened to these coils but they leak spit and burn out really quickly. some last for only 1-2 days and I am not a heavy paper. Once the next box is finished probably very soon I will change my brand of vape kit

By Joe from London

Do not buy the 1.7 Ohm coils (29 August 2023)

The 1.7 ohm coils are so unbelievably bad. More juice comes out the bottom than actually ends up being vaporised and they burn out so unbelievably quick which is insane considering that most of the nicotine you absorb while using these coils will come from the juice leaking out and being absorbed through your skin.

They also make an insane amount of noise, there's an intense sizzling sound, even with my vape on the lowest power setting.

Do not buy the 1.7's, the 2's lasted ages and the 1.5's would burn out quick but without all the leaking.

Now that you cannot get the 2's I have to find a different vape to continue my taper.

t18e (10 August 2023)

2 out of 5 pack was faulty made already, impossible to fit as silicone bits was all messed up. burnes oit very quickly, 1 coil lasts 1 to max 3 days. hugde dissapointment, as I'm not even a heavy vaper

By Chris from Hampshire

These used to be good... (20 June 2023)

Burning out after 2ml of juice.. avoid these.. probably going to get a different kit now... innokin gone downhill

By Scott Chegg from UK

I've given up... (02 June 2023)

Previously wrote a review titled "Generally good coils" on 25 April 2023.

Unfortunately, after opening the pack of replacement T18E coils that VapeClub have provided, the first two coils simply don't work... Not VapeClub's fault, but it's clear that the quality control at Innokin has fallen off a cliff in recent months.

I've given up and bought a new vape pen from a different brand. I'm fed up of wasting money on coils and the juice that gets wasted.

By Chris from Hampshire

Ok but... (31 May 2023)

These work ok, but the brown box version not as good as the old white box version... however, i think the new version may last longer when the juice level in the tank is low, but doesn't seem to give the same amount of draw/puff... more trials needed...

Generally good coils (25 April 2023)

I've been using these coils in an Endura T18II for about 18 months now and they are usually very good.
The last pack ordered had a couple of faulty coils that didn't fire at all, but VapeClub kindly replaced the pack as soon as they were notified.

Quality has taken a nosedive off a cliff! (18 April 2023)

I've been using the 1.5 T18Es for years, and to begin with they were great. I had some last for a month of daily use before failing or burning out.

In recent months it became common to have them sometimes burn out in less than a day and have one in a pack of five fail immediately, but I persevered until my most recent pack. Three of the five failed immediately wasting three tanks of liquid.

I'll not be buying these again.

By Liz from Uk

No flavour (18 February 2023)

I’ve tried several of the 1.5 coils in 2 different endura t18 ii and none of them have worked. I’ve left to stand for over 20mins each time and they just have no flavour. Vape appears but that’s it…. I’ve ordered the 1.7 coils to see if they work but so far out of 7 coils I’ve had no flavour at all. So disappointing :(

On a plus vape club have really prompt service/delivery.

By TM from Wiltshire

Extremely hit or miss (13 January 2023)

Been using the 1.7 coils in my T22 Endura Pro for nearly a year, when you get a working coil they're great but over the last few months or so it's basically a coin toss as to whether you get one that lasts over a week or one that burns out within hours/days.

By Dan from Durham

they work perfectly (12 January 2023)

nothing special with these coils as they are simple but work great, the flavour you get is as good as you can get with a vape that costs 20 quid lol. they do the job and im happy with them

By Liz

Not the best (06 January 2023)

I’ve used these coils for years but lately they have gone hit and miss. I often put a new one in and it doesn’t work at all and ends up straight in the bin. I thought it was my device so bought a new one but it’s still happening. Also sometimes they last a week and other times a day before they start to burn out and it’s not the juice as this has happened when using the same juice. It’s annoying feel like I’m wasting so many coils at the moment. I now prefer the disposables as it’s less messing around but it’s a lot more costly

By Josh from Uk

1.7 pro (25 October 2022)

1.7 pro coils are awful. Using a 50/50 liquid burns out in 1 day went through 4 packs and cost me so much money in the process. DO NOT USE THESE
