Safety Guide For Mech Vape Mods

The mechanical mod is the final frontier of vaping, the pinnacle of experience and courage. Hyperbole aside, using a mechanical mod is perhaps the rawest kind of vaping possible – thanks to it’s unregulated output. It’s important to remember that a mechanical / unregulated vape device is recommended to only the most experienced users out there. Users who have an extensive knowledge of battery safety, battery output, Ohm’s law and vaping as a whole.

Vape grandmasters will tell you that using a mechanical is an experience unlike any other. Through the simple act of pushing a fire button you complete a circuit that runs the power of your  vape battery through your unregulated device and into your RDA. With this in mind, we’d like to talk you through a few points of safety to help you get the best experience when using your mechanical mod.

How Low Can You Go?

You know that old saying – ‘just because you can, doesn’t mean you should’ well that applies to vaping as much as anything else. Yes, you can put a build below 0.2 Ohm into your RDA and fire it on your unregulated device, but here’s the thing – the lower the resistance the more likely it is that you run the risk of a flow of power that can cause the battery to vent, or in extreme circumstances cause a thermal runaway. To avoid this risk build coils at 0.2 ohms or above, you’ll get plenty of cloud and more importantly peace of mind.

The Right Tools For The Job

An Ohms reader or Ohmmeter is an essential piece of kit for anyone who is looking to build their own coils. Doubly so for those who are looking to move to using an unregulated device. A Ohmmeter allows you to check the resistance of your coil, if there are any short circuits, and that your coils are correctly fitted. If you were to skip this vital stage and fire your RDA on your mechanical mod without checking, the results can be deadly. The same can be said for a coil building kit, these specially designed vape tools allow the user to build coils efficiently and effectively, and increase safety. the Coilmaster V3 Kit contains not only the proper tools but a working ohmmeter.

The Coil, The Battery, The Relationship

We talked earlier about the danger of building a coil with too low a resistance, It boils down to the relationship between the battery and the coil. The rule of thumb is, the higher the Ohm rating the less Amps from the battery are needed. This is where Ohm’s law really comes into play. it’s used to confirm that the amount of energy you are discharging from your battery is safe.

‘I = V / R’ is the equation that will decide it all for you. Where ‘I’ is Current or what we call Amps, ‘V’ is Voltage, and ‘R’ is Resistance. Let’s do an example (it’s just like school but with more fun clouds’).

You have a fully charged LG HG2 18650 3.7V 20A Battery, and an RDA with a registered 0.3 Ohm coil build.  3.7 divided by 0.3 equals 12.3. Meaning this build will draw 12.3 Amps from the battery, this is perfectly safe for a 20 Amp battery; making this a practical combination of coil and battery to use with an unregulated device. Remember to keep your batteries charged as voltage can drop and this will have an adverse effect on your vape.


The above tips are a good jumping off point and have hopefully supplemented your vaping knowledge. When using dual battery mechanical mods, the rules take on a new dimension of complexity. We recommend you read up thoroughly on the difference between series and parallel circuits, and remember the golden rule ‘if it doesn’t seem safe, don’t do it’. We can’t reiterate this point enough, if you do not have the correct tools, vape hardware and knowledge you’ll be setting yourself up for disaster.

We stock a number of unregulated mods such as the Geekvape Athena, Vandy Vape Pulse, and more. If you have any questions regarding this topic, or vaping in general please do not hesitate to contact us.
