I made a promise to someone that I would do my best to give the Innokin Endura T20 a fair and in-depth review. To do that meant that I had to spend a week, maybe two, living with this vape pen, using it several times a day, albeit not exclusively, and create a review that would express my honest views. It wasn’t easy to do.

PREVIEW: Endura T20 Vape Pen for Flavor Chasers - Spinfuel VAPE MagazineTo accomplish my review I had to use two Endura T20’s because the first one contained a DOA coil head, and since the package comes with just one coil, I had to open another complete starter kit. Luckily, we had a few here, otherwise this review would end now.

Innokin As Vape Company?

It’s not often we have the chance to review a new product from Innokin. Of all the major manufacturers of vape gear from China, Innokin releases the least number of products. Because of that, whenever Innokin does release something my attention is piqued.  The Innokin Endura T20 is certainly attractive, and it’s affordable, $22.99 at Vapor Authority, but is it the fabulous vaping instrument it’s billed to be? Is the Endura T20 the right choice for new Vapers? I think I have the answer…


The Innokin Endura T20 is one of the worst vape pens I’ve used in years. Don’t get me wrong, Innokin recently released a pretty terrific sub-ohm tank called the Scion, but with devices like the Endura series, included the T20, I’m just not impressed with the company anymore.

I suppose I was asked to review the Endura T20 because of the time Julia and I have been spending with the three SMOK vape pens lately. In practice though, the Endura T20 is nothing at all like the SMOK vape pens. For one thing, the SMOK pens actually work.

I honestly, and sincerely, wonder why Innokin is still in the vape gear game. If the Endura T20 is a device they are proud of, then perhaps it’s time to find another industry to play in.

I will give you the features and specifications below, but before I do that, I want to give you my “real world” report first. Because I had this horrid experience with TWO Endura T20’s, I’m ready to say that this could very well be your typical real world experience as well.

The Innokin Endura T20 Experience

After opening the box of the first Endura T20 I dug out the one-sheet manual and the USB cable. Before reading anything, I attached the USB cable to my computer and the T20 and allowed it to charge, fully. Apparently the battery was more than 90% charged because it didn’t take long to fully charge.

Reading the short manual, I learned that the Endura T20 came with a single 1.5Ω coil. Strike One. Had I been a customer instead of a reviewer, and had purchased this device, bought it home, and discovered that the coil was DOA (which is exactly what happened), the entire purchase would be put on hold until I purchased a pack of replacement coils, at the additional cost of $12.99 for a pack of 5.

However, even if the single coil head was functioning, how long would it function? A week? 10 Days? If any device comes with a single coil head, think twice. In fact, unless you’re ready to add a pack of replacement coils to the purchase, avoid it.

As is my usual practice, before using the Endura T20 I unscrewed the tank portion from the 1500mAh battery and reseated the coil. Innokin is still creating tanks that have coils with flat heads on the bottom, with two cutouts that secure the coil in place. Twisting the coil to fit the base of the tank, you’ll need to align carefully, and press down. Unfortunately, there isn’t a click sound or other indicator that tells the user the coil has snapped into place.

Once I secured the coil and reassembled the tank, I unscrewed the drip tip top cap that reveals the top of the coil head in the middle of the 2mL tank. I filled the tank, screwed the drip tip top cap into place, and attached the tank to the battery. I waited a good 30 minutes before using, to allow the battery to be fully charged and the coil to be fully saturated with vape juice.

I turned the battery on, pressed the fire button, did the preliminary short pulls with the drip tip, and…. Nothing. No vapor, no nothing. The lighting scheme that has been a part of Innokin for years indicated that the battery was indeed fully charged, but because the 1.5Ω Kanthal/cotton coil was DOA nothing happened.

I spent about an hour trying to reseat the coil, emptying the tank each time, and no matter what I tried it just wouldn’t work. Finally, I gave up, and grabbed another Endura T20 and started all over.

The second T20 did have a working coil, and I discovered while using the Endura T20 that it had the tightest mouth-to-lung pull I’ve ever experienced. Innokin says the Endura T20 is a flavor vape pen, but the amount of vapor from a 5-8 second pull was hardly enough to generate any flavor.


I was very disappointed in the Endura T20, but was determined to attempt to use it every day for a week. I thought maybe the coil would ‘give’ a bit, allow a somewhat looser pull, but that did not happen. But, I still picked it up every day, a couple times a day, and gave it a go. It did not improve. The Kit comes with two extra dip tips, neither one did any better than the original. (Maybe an extra coil would have been a better idea)

The Innokin Endura T20 may be an attractive and affordable device, but the number of other vape pens on the market that do a better job at about the same price, are too numerous for me to give the Endura T20 any chance at a score higher than F+.

I try to avoid recommendations, but I’ll make an exception here. Do not buy the Endura T20.
