The Aspire Kumo RDTA is a design collaboration between the Prestige Range at Aspire and Steampipes that appears to be a German Vape brand.

Of course Aspire have a huge back catalogue and their “Prestige” range includes the Boxx, Neeko RTA, Zero G and the Paradox Mod.

What To Expect From The Aspire Kumo RDTA…

This RTA is a bit of a game changer in terms of design and operation – I will try to describe how this works the best I can!

Usually with a RDTA the build deck is above the e-liquid chamber so you get all the flavour of an RDA.

We tell you what the terms RDTA, RTA and RDA mean in our Guide To Rebuildables.kumo design

However in this configuration you need a method of drawing the e-liquid up from the liquid chamber onto the deck. There have been cotton and wire wicking methods to do just this.

This time with the Kumo there has been a bit more thought put into this and the theory of “Pascal’s Law” triggered the design.kumo rdta liquid feed

A simple summary of Pascal’s Law is that if there are 2 areas with different pressures the higher pressure area will try to overcome the lower pressure and equalise the pressure everywhere.

So in this sense the RDTA has 2 chambers – the tank section with the e-liquid and the single coil deck section which is connected to the airflow inlets and outlet (mouthpiece).kumo rdta materials

The flow of air from the inlet to the mouthpiece creates a lower pressure than is in the tank section which basically sucks the e-liquid from the tank up to the deck and it is wicked through the coil as usual with cotton.kumo rdta adjust airflow

You can of course adjust the incoming airflow and there are 2 different airflow inlet styles included in the kit – you can choose which you find preferable to vape or which one you simply prefer the look of!kumo rdta airflow rings

To fill you remove the top cap to reveal the side fill port and at present I have only seen a 2ml capacity version available.filling

You can also replace the clear section with a stainless steel section which is also included in the kit.tank

There are 3 colours to choose from: Stainless Steel, Satin and Black Satin.

Also let me know if you think the Aspire Kumo RDTA is a game changer!

My name is Michelle - I am 46 and an engineer and Technical Author by trade. I started vaping many years ago in the days of Tornado tanks, Ego batteries and Variable Voltage. My journey in vaping began again a few years ago and have started to move up in the shiny shiny gadget department and love vaping! I have finally stopped smoking as of June 2019 and that is all thanks to vaping! 20mg Nicotine Salts are my hero! Oh and I am partial to a nice pod mod!
