Modern battery carriers (Mods) today offer an impressive variety of functions. But terms like TCR, Bypass or CCW often cause confusion for many vapers – whether beginners or advanced users. A large part of your device's potential remains unused.
In this guide from Myvapesite we will explain the most important steam modes to you, how they work and what materials you can use them with, to find your perfect vaping experience.
Battery carrier modes explained: VW, TC, Bypass & Co. use correctly (2025)
1. Variables Watt Mode (VW or POWER)
Watt mode is the most commonly used mode worldwide. It is uncomplicated and delivers excellent results for almost all evaporator heads.
- How it works: You set the desired power in watts. The battery carrier automatically calculates the required voltage (Volt) to match the resistance of your coil.
- Advantage: Maximum simplicity. You don't have to worry about technical calculations.
- Professional tip: Always start at the lower end of the manufacturer's recommended range (printed on the coil) and slowly approach your personal “sweet spot”..
2. Temperature mode (TC: In, Of, SS)
Temperature-controlled vaping (Temperature Control) is the second most popular setting. It is primarily used to protect against the dreaded “dry hit”. (burnt taste).
- How it works: You set a maximum temperature (ideal between 200°C and 240°C). The mod measures the change in wire resistance when heated and regulates the power, before the cotton can burn.
- Requirement: You need special wires like stainless steel (SS), Nickel (Ni200) or titanium (Of).
- Safety notice: Use nickel and titanium never im Watt-Modus, as these wires can release harmful substances if overheated!
3. TCR-Modus (M1, M2, M3)
TCR stands for Temperature Coefficient of Resistance. This is a professional mode for maximum precision.
- How it works: Here you manually enter the exact temperature coefficient of the wire you are using. This makes sense, if you use special wire alloys, which are not preset in the standard menu.
- Storage spaces: Most devices offer places (M1-M3), to save different setups.
Mode comparison: Which wire for which mode?
| Material | Watt Mode (VW) | Temperature Mode (TC/TCR) | Special feature |
| Kanthal (KA1) | And | No | The standard wire for Watt steamers. |
| stainless steel (SS316L) | And | And | Very versatile, best all-rounder. |
| Nickel (Ni200) | NO | And | Only suitable for TC! |
| Titan (Of) | NO | And | Only suitable for TC! |
| Nichrom (Ni80) | And | No | Fast heat-up time in Watt mode. |
4. Bypass-Modus
Bypass mode simulates the behavior of a mechanical battery carrier (Mech Mod).
- How it works: The control electronics are virtually bypassed. The battery delivers its full voltage directly to the coil. As the battery charge level decreases, the amount of vapor also decreases.
- Advantage: You enjoy the purist feeling of a mechanical device, but still benefit from the internal security chips (Protection against short circuits and deep discharge).
5. Smart-Modus (S)
Particularly integrated into modern devices from manufacturers such as Vaporesso or Voopoo.
- How it works: The chip detects the resistance of the inserted coil and automatically sets the optimal wattage. In addition, the maximum performance is usually limited, to avoid accidentally burning the cotton wool (z. B. in your trouser pocket) to prevent.
6. Performance curves: CCW und CCT
These are functions for foodies, who want to plan their move down to the second.
- CCW (Custom Curve of Wattage): You create a performance curve. For example, the mod fires for the first second 50 Watt (quick heating), and then up for the rest of the train 40 watts to sink.
- CCT (Custom Curve of Temperature): The same principle for temperature-controlled vaping.
- correction: This has nothing to do with “counterclockwise”., but is a purely time-based performance control.
Which mode should you choose?
It is for daily use Watt Mode the best choice for almost all vapers. However, if you are sensitive to burnt taste or use DIY rollers, It's worth switching to TC-Modus. Use professionals CCW-Kurven, to get the maximum flavor out of your liquid.
Do you have any questions about setting up your device?? The team of Myvapesite will be happy to advise you, so that you can exploit the full potential of your battery carrier!
