What is a mechanical mod?
Mechanical mods demand user knowledge of ohms law, lithium-ion battery safety, and electrical conductivity.
A mechanical mod is a simple yet advanced vaping device that delivers raw battery power to an atomizer without electronic regulations, safeguards or protections for the user. For knowledgeable hobbyists, this allows for a wide degree of customization depending on the batteries used, the build of the atomizer and the materials used on the mech mod itself.
There are just a few parts to a mech mod:
- Battery housing: Most often in metal tube form, though mechanical box mods are also common in wood or plastic. Tube mechs typically only take one battery where boxes can house one or more cells.
- Positive and negative contacts: The positive connection is in the top cap and the negative contact is in the button which is typically spring loaded.
- A button or switch: The button completes the electric circuit when pressed. Many buttons on tube mods are recessed to avoid accidental “firing,” or have built-in locks for when not in use.
- 510 connection: Built into the top cap of a tube mod or on the top of a mechanical box, the 510 connection is a type of threading that electrically connects the atomizer and mod. An atomizer has the male end of the 510, and the mod has the female end. There are positive pins inside of the atomizer and the mod’s 510 threading, typically made of copper or brass, that contact each other to deliver power.
Unlike the industry-dominant regulated box mods, mechanical mods will send battery current to an atomizer regardless of its resistance. That means that even if your atomizer has a short or a dangerously low resistance for your chosen battery, a mechanical mod will still power it and continue to power it if the button is pressed, which could lead to catastrophic battery failure.
What is a hybrid mech mod?
Warning: it’s strongly recommended for the average user to avoid hybrid mechanical mods.
A hybrid mech mod is a mechanical metal tube mod with serious and inherent risks beyond the typical mechanical mod. A hybrid mech mod differs from a traditional mechanical mod in one way: there is no insulated 510 contact in the top cap of the mod. The atomizer’s 510 pin makes direct contact with the positive terminal of the battery, delivering power more quickly than a typical mechanical mod due to less metal the current travels through.
In the early days of e-cigs, atomizer threading was considered proprietary and meant to only work on a given brand’s devices. Now, 510s are standardized, enabling almost any brand’s atomizers to work with almost any brand’s mod. The danger with hybrid mechs is that almost all atomizers will fit, but very few were designed to work safely on them. Here’s the problem:
The metal threading of an atomizer’s 510 is a negative ground insulated from the positive pin that sits inside of it, but the pin doesn’t stick out very far from the threading (maybe a millimeter or less). In normal mods — all mods separate from hybrid mechs — the pin doesn’t need to stick out far, if at all, because it only touches the mod’s insulated positive pin. But In a hybrid mech mod, there’s typically not enough clearance between an atomizer’s negative threading and the battery’s positive terminal. Because of that, there is a chance the atomizer’s negative threading will make contact with the battery’s positive terminal which would result in a dead short, possibly leading to thermal runaway (a battery violently venting like a roman candle.) For this reason, it is strongly recommended to steer clear of these devices.
Are mechanical mods right for you?
Mechanical mod vape devices represent a niche and hobbyist segment of the market and are not the type of devices to “learn on.” Vaping is meant to be a safer alternative to smoking, and one should always keep that in mind no matter what you see others doing in vape shops or on YouTube. There are no advantages to using a mechanical mod over a regulated mod that warrant the risk for the average user.
