IJOY RDTA 5S review by Dan Willis

Review Date: 


IJOY have become a very well known brand name within the industry, with a string of releases such as the Captain PD270, Captain Sub Ohm Tank, Maxo and Tornado RDTA not only endearing themselves to cloud chasers, but proving to be smash hits for IJOY. One of the latest products from the IJOY stable is the RDTA 5S, the sixth generation of their RDTA series.

IJOY's RDTA 5S implements an innovative central filling system, a two post gold plated build deck set up to handle large coil builds, a dual bottom and side adjustable airflow system and a push and lock body section which is designed to protect the glass and make wicking easier. It has a 2.6ml capacity, and is also available in seven different colours.

What's in the Box?

Design and Build Quality

IJOY's RDTA 5S is a 24mm width RDTA manufactured from stainless steel with a glass tank section. An 810 drip tip fitting is present at the top to accommodate wide bore drip tips with an Ultem wide bore drip tip pre fitted, no 510 drip tip adaptor was present in the spares pack to enable you to use narrower bore drip tips. A gold plated adjustable 510 connector pin is located at the bottom of the tank, it seems to protrude out quite far but didn't give me any gap issues with the mods that I used the RDTA 5S on.

The top cap sits snugly on a single o-ring, popping on and off nicely without too much hassle. You can push the build deck through the body section located at the base, giving you full access to the deck and thus making it far easier to wick. The body section and build deck lock into place via the two notches cut out on the deck. You can also fully strip down the RDTA 5S without much hassle, making it easy to clean and maintain. 

Capacity is 2.6ml, and refilling is done by either saturating the deck with juice until it drips down into the tank section, or by filling through the fill hole located in between the posts. You do need to take care not to knock your build when filling through the central fill hole, I found it easier just to drip juice through the drip tip down onto the deck when refilling.

Building the IJOY RDTA 5S

The IJOY RDTA 5S features a two post build deck, set up for dual coil builds, with a good sized amount of space for building coils. The post holes themselves are wide enough to accommodate large coil builds, with the grub screws fastening the coil legs down nicely. You do get two pre made fused clapton coils included, which have a final resistance in the 0.2ohm region when installed.

I found wicking to be a complete doddle, you can push the deck out from the bottom body of the tank and slip the glass tank section off giving you full access the deck, it's simply a case of aligning your wick tails with the cut outs at each corner of the deck and popping the glass tank section and bottom body back over the deck. The deck clicks back into place through the two grooves cut out at either side, meaning everything lines back up perfectly.


Side and bottom adjustable airflow is found on the IJOY RDTA 5S, the side airflow is adjusted via rotating the airflow control ring at the top of the tank, and if you wish to close off the bottom airflow entirely then you can rotate the top cap so that only the two dedicated side airflow slots are in play. Airflow ranges from a wide open airy lung hit, to a restricted lung hit when the side airflow is shut off completely and bottom airflow is closed right down.


I installed the two supplied fused clapton coils, which gave me a final resistance of 0.2ohm, and these fitted perfectly with room to spare. The IJOY RDTA 5S is manufactured to handle low resistance builds used at high wattage settings, as with many of IJOY's other products, and I found that 80-90W was an optimum setting for the build I used. The top cap did get quite hot during frequent use, however the Ultem drip tip stayed cool preventing the heat from transferring to my lips.

The flavour I got from my vape seemed to be a marked improvement over the previous RDTA's I have tried from IJOY, namely the Limitless RDTA and the Tornado RDTA, with a clean and crisp vape full of flavour. I found flavour was better with the bottom airflow set open as well as the side airflow, it was definitely more muted when the bottom airflow is closed off. The IJOY RDTA 5S is a little on the noisy side however with the airflow wide open, making a loud 'whooshing' noise, and I did get the occasional spitback issue.


I've found that the atomisers I have used from IJOY have excelled at producing clouds, and the RDTA 5S is no different. This can seriously kick out a large volume of vapour with little fuss, enough to fog a room out in no time at all!

With the capacity set at 2.6ml, juice doesn't hang around long in your tank. With the build I used, I found that I was having to refill the RDTA 5S frequently throughout the day, which came at no surprise given the amount of wick used and the wattage settings I was using!


The IJOY RDTA 5S is another impressive piece of kit from the IJOY stable, I have found it to be one of the better performing RDTA's that I have tried, and certainly the best one I have tried from IJOY to date. The ease of build and wicking was a particular highlight, enabling me to get the RDTA 5S up and running with virtually no fuss at all, and the flavour and vapour was particularly enjoyable too. It's definitely well worth having a look at!

Many thanks to efun.top for sending the IJOY RDTA 5S into POTV for review!
