The Tube Mod By Cthulhu Previewed

The Cthulhu Tube mod is a new Semi-mechanical mod from the brand who usually creates atomisers!ct tube mod with tank

This is a versatile and stunning little mod with added safety features too!ct tube mod 22mm 24mm

The mod in the small version can uses a single 18350 battery. However install the included extension tube and you can also use a 18650 battery.ct tube mod battery types

To help with safety there is a MOSFET chip installed on the mod.ct tube mod chip

This basically means there are some circuitry protections. If there is a short circuit the mod will basically not work as the chip will not supply the battery power.ct tube mod vents

Also the internal surface where the battery lives is insulated – and apparently Cthulhu say even torn battery wraps will not cause a short circuit. Not that I would want to even put that to the test! Make sure you are clued up on your battery safety!ct tube mod insulators

On the side of the mod is the fire button – there is not full battery power to this button it simply acts as an “activator” for the MOSFET chip and the chip then connects the full battery power to the 510 connection.ct tube mod fire button

I have seen a statement on the Cthulhu Facebook page today (24/2/19) regarding an early version of this mod – which is on pre-order and it appears there are some modifications being made. I am not sure if any have been shipped prior to this or if this affects pre-orders only.

“Dear customers (who preordered our tube mod),
We are very sorry for those troubles you got.
Our team change the connector pin material, adjust circuit parameter (to reduce fire-delay, and improve the yield of good chip), and add liquid proof coating.
We will send new chips to all pre-orders (order from cthulhu or other retailers).
New batch will use improvement chips too.
We are testing improved chips with new testing equipment now.
Our team will post testing result next week.
Many thanks!”

I have to say this is a tiny little cute mod. The addition of the chip does make it more appealing to me – however this has been done before by other manufacturers of Semi-regulated devices.

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!
