TECC D20 Kit Review by Antony Lord

TECC D20 Kit 

Today I’m looking at the second budget starter kit sent over by The Electronic Cigarette Company, and this time it’s the TECC D20 kit (aka the Eleaf iJust 20), a modern take on the classic pen style kit. This is just £22.99 and at the time of writing you'll even get two 10ml bottles of e-liquid thrown in as well.


  • 131 x 20mm
  • 67.3 grams
  • 1500mAh battery / 2 amp charging
  • 3 adjustable power levels (max 30 watts)
  • resistance range 0.4~3.0ohms
  • 2ml tank
  • GTL coils (2 x 1.2ohm coils provided)

TECC D20 Kit packaging and unboxing

The contents of the box are fairly basic with the D20 itself, a USB-C charge cable, and two 1.2ohm GTL coils. I was sent the black version for testing but it’s also available in pink and silver. 

TECC D20 Kit manual


One of the things I was most impressed with is the user manual, the first ten pages cover the basic setup and operation of the D20 kit in a clear pictorial  style which is perfect for the first time user, top marks to TECC for that one.

TECC D20 Kit details

The D20 is your classic cylindrical “pen” style device with a battery at the base and a tank at the top. You have a large power button surrounded by an LED ring on one side and a USB-C charge port on the opposite side, the base has a nice rubber finish so it won’t scratch any surfaces if you have it stood upright.

The large LED ring around the power button indicates the current charge level when you take a vape (green over 60%, red below 20%, and blue in between). You also have three adjustable power levels by pressing the power button three times (red is low, blue is medium, and green is high) which is something we don’t always see on these more budget minded kits.

The D20 features 2 amp USB-C charging and in my tests this actually hit a peak charge of 1.89 amps with a 1498mAh recorded capacity. This means that the D20 battery charged in a rather impressive 59 minutes, with the supplied 1.2ohm coils this will run for quite a while between charges as well and I got a rather impressive two days out of it.


TECC D20 Kit airflow and connector

Just below the tank you have an adjustable airflow ring with seven holes so you can take this all the way from an eye watering single (0.8mm?) hole up to a fairly airy direct lung draw (not with the included coils though). Of course as this is a modern take on a pen style kit the tank is actually a “pod tank” which sits in the propriety recess at the top and is held in by magnets, this means that you’re locked into the GTL coils and D20 pod/tank. There’s a small autodraw sensor hidden in this top area as well.

TECC D20 Kit tank and coils

The D20 pod/tank has a removable 510 drip tip and a push to fill top, this is held firmly in place by a small ball bearing on the underside so I’ve not experienced it coming open in pockets etc. The fill port is also a decent enough size so it’s been a pleasure to use. This has a 2ml capacity and I’m assuming it’s probably PCTG but I can’t find any mention of that, should the worst happen a replacement pod is available separately for just £3.49 in any case.

This uses the GTL coils which use a kanthal mesh coil which are simply press fit into the base of the pod. Both of the coils supplied in the D20 kit are the 1.2 ohm mouth to lung (MTL) variety so this has obviously been aimed at first time vapers. It is compatible with the Eleaf GTL coils as well though which are available in 0.8 and 0.4ohm kanthal mesh if you want to experiment with a more cloudy vape.


With everything set up, I set off with the lowest power setting and dialed the airflow into my preference as I prefer a looser MTL vape, the autodraw feature worked well enough here but I found myself preferring to use the power button instead most of the time. At this lower setting I did find there was a tendency for the coil to flood periodically and there was quite a bit of leaking underneath, bumping the power up to the medium or high settings seemed to solve this though. The flavour from the coils has been great and I might even experiment at some stage and try this out with some of the 0.4ohm Eleaf GTL coils.


  • Fast charging
  • Inexpensive
  • Kanthal mesh coils


  • Coil did tend to flood at lowest power setting


A great budget entry point into the world of vaping, The Electronic Cigarette Company D20 kit is a good place to look if you’re a new vaper. Although you only get the 1.2ohm mouth to lung coils included, this is also compatible with the Eleaf GTL coils if you want to experiment with a more airy direct lung vape down the line, it also means it should be easy to find coils as well.

Many thanks to The Electronic Cigarette Company for sending the TECC D20 kit over for review.

I was a twenty a day smoker for 25 years and like most smokers I was always going to quit "next week". Having hit my mid forties and having the usual smokers cough and difficulty with anything more than moderate exercise it was obviously time to give up the cancer sticks. I tried vaping in 2013 but it wasn't until 2016 that I fully made the switch and gave up cigarettes completely.
