Innokin iSub G - 4.5ml Tank

Model:  INISGT

The Innokin iSub G is a 4.5ml glass alternative to the brand's top selling iSub Tank (4ml). Just like the later, the iSub G features premium quality stainless steel construction but it comes with a larger tank capacity as it can hold as much as 4.5ml of E-Liquid for a longer lasting vape.

Minimalistic, sleek yet highly elegant design is another striking feature of the iSub G tank. Though clearly inspired by the iSub's design, the actual tank is made of premium quality Pyrex Glass. The iSub G also features two 0.5 Ohm coils, Japanese organic cotton for better wicking, the Innokin's revolutionary “No-Spill Coil Swap System” and fully adjustable airflow.

All in all, you can expect a top performing, easy to use and extremely durable tank which offers premium taste, incredibly rich flavour, great clouds and plenty of style, especially if paired with the ultra-modern Innokin Coolfire IV box mod.

Remove the iSub G 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.

Excellent tank
Friday, 6 November 2015  |  Dan

Great tank, huge vapour and liquid tastes great. Easy to refill and coil unscrews separately from filling department. Using it on the eVic-VT 60W at 25W full air flow and produces massive clouds on a higher VG liquid. Wish I brought one sooner.

Top Quality!

Do not be put off but other reviews. (AMATEUR!)
This is a top quality sub ohm tank with massive clouds. Search for any professional review and you will see they agree with me. If you're burning your lips, then use variable wattage rather than volts on you device! Should be run between 20w & 35w as specified on the packaging.
Top quality, completely breakdowns so you can clean every part. Coils cheap and long lasting. You wont regret one of these, just come prepared with knowledge or a will to learn if you haven't sub ohm'ed before.

Am using this Innokin sub tank G with the Innokin Cool Fire mod. It is ok I guess, although it does slightly burn my lips, even on a low wattage and it makes my throat very dry and slightly sore after one days use. It doesn't produce as much vapour as I would have expected. Will only be using it as a spare, instead of the main one which I intended. Still think Kangertech is the number one product.
