Sub ohm tanks have brought RDA and RBA cloud vaping to the masses. Prior to the Sub-Ohm tank if you wanted to get an amazing vape with the ability to blow out clouds of vapour you would have had to purchase a RDA or RBA tank and learn to make your own coils isn’t an appealing option to a lot of vapers.. The latest sub ohm tanks now allow you to replicate the experience you would get from an RDA or RBA with the convenience of a normal clearomizer. This means you can insert pre-made coils into the tank, as would have done previously on other clearomizer / tank devices like the Nautilus or Aerotank etc. This ease of use, combined with the fact that you are now able to enjoy the incredible flavor from your e-liquids and billowing clouds of vapor, make the new sub ohm tanks a very popular choice. N.B. YOU MUST HAVE A POWERFUL BATTERY OF LEAST 30 WATTS
