The Innokin Kroma A iSub B vape kit has been designed as a reliable sub ohm kit. Powered by a large capacity built-in 2000mAh battery, it's capable of a 75W maximum output to help you experience better vapour and flavour production. The kit comes complete with the iSub-B tank, that features a 2ml capacity and top filling.

Compact in size, the kit features an ergonomic design so it fits better in your hand. The mod also benefits from pass-through charging capabilities, meaning even while charging the Kroma-A it can still be vaped. On OLED screen clearly displays information and the simple menu system, is easy to navigate.

Users have the option of multiple output modes to suit their vaping style. Variable Wattage (most recommended for newer users) allows you to directly control power output between 2 - 75W helping you find a balance between cloud and flavour production. You can also match power to the resistance of your coils.

Temperature Control Mode (recommended for advanced users) lets you select a maximum temperature your coil can reach before the device will stop firing. The device will regulate wattage to stop a dry hit occurring. 

The Innokin iSub-B tank is an innovative vape tank that has been created to offer increased cloud and flavour production. Easy to refill, the threaded top cap can be removed to reveal a large juice port that will fit most bottle nibs. Allowing for a direct to lung inhale, it’s dual adjustable airflow allows for increased or decreased vapour creation.

The 0.35 Ohm Plex3D coils feature advanced mesh coil technology complete with micro-grooves which in turn increases surface area for denser flavour. Featuring organic cotton/wood pulp coils, meaning you'll experience a balance of flavour and cloud creation with every vape.

Due to the coil resistance, we recommend using high VG eliquids of 60% VG or above, for best performance.

Important information about sub ohm vaping:

This device is intended for sub ohm vaping. Sub ohm vape kits require a greater amount of knowledge and experience to use safely. They use specially designed coils that register below 1.0 Ohm resistance, for use at higher wattages. These kits will also feature advanced modes that require a knowledge of vaping to be used correctly.

We recommend you do not use an e-liquid that has higher than a 6mg nicotine strength, this will be too harsh on the throat. Sub ohm vaping produces more vapour and because of this, an increased throat hit. High VG e-liquids will allow you to experience greater vapour production when used with this kit.

Simply the Best (19 June 2019)

Since I started vaping 4 years ago, I mostly used Aspire tanks. The main ones I used were the many variations of the Nautilus tanks. I thought they were the bees knees until I used Innokin. They fill easy, they don’t leak and the price is great. I dabbled with sub ohm but never seemed to get it right. But this time it worked and I now know why people do it. The flavour is so much better and the clouds, I had to put my extracter fan on. The only downside of the tank is it gets very hot. A better drip tip may do the trick. I’m going to shop around to see what I can find. The mod is excellent. The great thing about Innokin is that everything is so intuitive and easy to use. It fits great in the hand and it looks nice too.

Innokin always make a winner (24 May 2019)

Super little mod, great design, fits in the hand nicely. I went for the Rose Gold which looks good! If you vape on a low wattage, this is perfect! Easy to use mod, but the I-sub tank’s mesh coils kept burning out, as there’s very little cotton in them.
Kept the tank as spare but using a Vaporesso tank with ceramic coils. Now I have an awesome set up, love Innokin products as they’re simple but effective. Well made and good looking little mod.
