Innokin iSub Tank - 4ml Tank

Model:  INIST05C

The Innokin iSub Tank is a 4ml capacity tank featuring two 0.5 Ohm coils, German Made P.C., Japanese organic cotton, adjustable airflow and “No-Spill Coil Swap System” for more and larger clouds and the finest flavour. And it is available at the fraction of the cost of comparable quality sub ohm tank systems.

Designed to offer the most enjoyable vaping experience possible, the Innokin iSub was also designed to look aesthetically pleasing. It has a very clean and simple design, while the combination of polycarbonate and stainless steel make it appear highly sophisticated. To suit individual style preferences, it is available in the following colour options: Clear, Black, Pink and Blue. All are transparent so that you can determine the levels of E-Liquid. You can choose the preferred colour in the drop down menu below product information.

NOTE: This item is only suitable for SUB ohm batteries, Mod's and Box Mod's

Please keep in mind that coils should be replaced every 2 to 3 weeks, ideally before the E-Liquid starts to change the taste or the device stops producing vapour. You can find iSub replacement coils here.

Remove the iSub from the tank  by gripping the base and turning anti-clockwise. With the tank turned upside down drip the liquid down the inside outer wall. Do not fill above the top of the inner air tube.

Once you have filled the tank section with liquid then replace the Base section by turning it clockwise untill tight, be sure not to cross thread or over tighten.

To change coil, unscrew the base of the tank to expose old coil, twist the old coil and turn anti clockwise until it detaches from the base. Replace with new one and refill tank. Let the e liquid soak into the coil for 5 min before you switch the device on. This will avoid burning out your coils.

Great product

This is a good tank to start out with. The tank can leak but this is a sign that it is time to change the seals which are provided with the tank. Would recommend for anyone starting out

Bought this as a backup for my Aspire Triton tank which I use with the Innokin Cool Fire IV Mod. It has proved to be an excellent inexpensive purchase and I love it's clean uncomplicated design.

iSub tank

Nice tank easy to fill and holds nice amount of juice. Needs to have. 1.5 ohm coils available. Had to buy 2.0 ohm's as my device would not fire the 0.5's supplied.

innokin I sub tank
Sunday, 1 May 2016  |  Chris

This is the first innokin product that I've bought. I was very impressed with the performance and the tank is easy to dismantle and re-fit. The only slight drawback I've found is that the mouthpiece is very large and wider than most other sub tanks that I use. However' ala in all a very good purchase. I'd definitely reconsider buying another.

I sub tank
Saturday, 5 September 2015  |  David

Very easy to use, you need to add 3 drops of liquid to the top of the coil before using it and then fill to 3 quarters. Wait 5 mins for the liquid to soak into the coil then ready to go. There are airholes on the side you can adjust to create bigger clouds which are massive in any case.
With sub ohm tanks you need a thick liquid because of the intense heat that is generated by the tank. If the liquid is too thin it will leak through the coil but this is not the tank at fault, it is the liquid. You need a minimum 70% vg juice which is what these tanks are designed for.
Be warned though, sub ohming burns a lot of liquid.
