*Please Note: This is a Semi-Regulated Mechanical Device designed for advanced users, please read this description in its entirety*

The Acrohm Fush is a semi-regulated mechanical mod, recommended for expert users only, it combines the stylings and raw power output of a classic mechanical device, with a built-in chipset to increase safety when used. Powered by a 18650 vape battery (sold separately) it is capable of a 40A bypass current and can be paired with a range of rebuildable atomisers.

The Fush features one mode - Mechanical Bypass, again, much like classic unregulated devices, power in watts is dictated by the amp output of your battery, it’s voltage and the resistance of your coil. We recommend that users have an extensive understanding of Ohm’s Law, battery safety and rebuildable atomisers before using this device.

The benefit of a mod like this is that has a very fast ramp-up time and offers enhanced cloud and flavour production. Unlike unregulated devices, the Fush has an inbuilt chipset which provides a number of safety features, including Overload Protection, Short Circuit Protection, Overheating Protection, Low Voltage Protection, Reverse Protection, and Overtime Protection in the form of an 8-second cut off.

Fitted with a hybrid 510 connection it is designed explicitly for use with RDAs, RTAs and RDTAs that feature a protruding 510 connection only. The benefit of a hybrid cap is that the firing pin of your RDA comes into direct contact with your battery for a faster ramp up and a harder hit overall.

A built-in LED lights up when the device is fired, you have the option of changing the colours shown, for a unique aesthetic. Rather than menu systems or a user interface, this can be achieved by clicking the firing button on the base of the mod. This button can also be used to lock and unlock the device by clicking it five times.

Top Tips - Mechs Are Intended for Advanced Users ONLY

  • We don't recommend building below 0.2 Ohms
  • Always use an Ohms Reader to check resistance before using
  • For low resistance builds use high amp batteries
  • Ensure your battery wrap is intact
  • Ensure your locking switch is activated when not in use
  • Store your batteries safely in a case, never loose
  • Use a dedicated charger for batteries
  • Never leave charging batteries unattended
  • Dispose of batteries responsibly
  • Avoid short circuits by ensuring coils are installed as per manufacturer instructions

Battery / Amperage Guide (Do Not Exceed Limits):

Please note this information is based on continuous discharge rates of batteries, not pulse discharge.

  • 1.0 Ohms - 4.2A Amp Draw
  • 0.9 Ohms - 4.6A Amp Draw
  • 0.8 Ohms - 5.2A Amp Draw
  • 0.7 Ohms - 6.0A Amp Draw
  • 0.6 Ohms - 7.0A Amp Draw
  • 0.5 Ohms - 8.4A Amp Draw
  • 0.4 Ohms - 10A Amp Draw
  • 0.3 Ohms - 14A Amp Draw
  • 0.2 Ohms - 21A Amp Draw (RECOMMENDED LIMIT)
  • 0.1 Ohms - 42A Amp Draw (NOT RECOMMENDED)

Please note: This is a mechanical/semi-regulated vape device it has none of the safety features of a regulated device; by pushing the fire button you complete a circuit that directly runs power from your battery through the device and into your RDA.

We do not advise under any circumstances for a mechanical device to be used without a thorough knowledge and understanding of battery safety, battery output, Ohm’s law and vaping in general. This is a vape device for very advanced users only - this should not be used by beginners or casual vapers. If you have any questions or queries regarding mechanical devices or vaping in general, please contact us.

Nice For Collection (09 August 2019)

its a nice disco mod with all the different collors that the mod has.
Good for people who wanna get the feeling of a mech mod but still with safety's build in. Its still on the big side if you would like a tube mod with safety i would recommend buying the SoulKeeper mod.
!!!! but still keep in mind the Ohms law + battery safety those are still important even with this type's of mods !!!!

The Clubbers Mod (11 June 2019)

Interesting bit of kit. It's like a mini light sabre but still too big to open your letters with. It's not a hybrid top cap as is stated in the description. You can even use your sub-ohm tanks on it. Has all the protections and also doesn't require much maintenance compared to an actual mech mod. No button to clean. In fact the button on the bottom isn't actually mechanical. It has the same form factor but actually works as a virtual switch, sending it's signal up to the chip. The latest edition also includes memory for the lights in the device, so turning it off and on doesn't reset it, unlike the release version. No one's mentioned it but I have noticed it. So, if you like the mech mod form factor but don't want to get in to them because you are worried about the safety aspects then this is perfect. Build quality is great. But I have to mention that it doesn't kick anywhere near as hard as a mech mod. I'm running a 0.3 ohm build that isn't demanding for a 25amp battery but notice what feels like a huge voltage drop from a fully charged battery. Feels as though, for safety, it fires the coils slightly under powered, giving a medium heat vape but the power feels consistent throughout up until it flashes to tell you that the battery is low then stops firing. Almost feels as if the chip reads the resistance and sets a wattage/voltage accordingly. Even though it says above not to use bellow 0.2 ohms it can read up to much lower, but won't perform as well. I think it just sets a wattage and believe the highest it can go to is 80w. So for intermediate users it could be a cool bit of kit. The way in which it lights up looks really cool, no flashing or strobing or multicoloured effects. It's either a solid colour or turns on when fired depending on mode and you can set your colour. And even though I like my LEDs I think someone who doesn't might appreciate the simplicity of its use of lights. I've noticed that when I take this mod out to card or sports nights with friends they are intrigued, where as most of my other mods go unnoticed. So definitely an attention grabber. Even though performance is underwhelming compared to actual mechs I still really like it. It looks sexy, especially in black with a black Gear RTA sat on top. Ideal for single coil builds. But definitely run a high amp battery like Samsung 25R for best hit. Another major con for me is that considering how big this thing is, it only uses 18650 batteries. Would have been really great if it used 21700's. Finally I think more advanced users may not enjoy the experience compared to an actual mech but it really shouldn't be compared to them. It's chip may be basic but it is definitely doing some auto-regulation behind closed doors. I've actually really enjoyed the experience. Great bit of innovation.
