What Is a Box Mod?
A box mod is a type of vape device that offers advanced features, higher power output, and full customisation over your vaping experience. Unlike simple pod systems or starter kits, box mods give you control over wattage, temperature, voltage, and more, allowing you to fine-tune every aspect of your vape.
Box mods have become a favourite among experienced vapers for several key reasons. They're called "box mods" because of their rectangular, box-like shape, which houses larger batteries, advanced chipsets, and comprehensive control systems.
Most box mods use removable 18650, 20700, or 21700 batteries, giving you the flexibility to swap batteries and extend your vaping time without waiting for a recharge.
With wattage ranges typically between 80W and 200W+, box mods deliver the power needed for sub-ohm tanks, rebuildable atomizers, and high-performance
Box mods stand out from other vape devices thanks to their advanced capabilities:
- Advanced chipsets with multiple vaping modes
- Variable wattage (VW) and temperature control (TC)
- OLED or TFT screens displaying real-time data
- Safety protections, including short circuit, overcharge, and overheat prevention
- Compatibility with a wide range of tanks and atomizers
- Durable construction designed for long-term use
If you want full control, powerful performance, and the ability to customise your vape, a box mod is the ideal choice.
Which Should You Choose?
If you vape at 50W or below and want something portable, choose a single-battery box mod. If you enjoy high-wattage sub-ohm vaping and need all-day battery life, choose a dual-battery box mod.For most experienced vapers, dual-battery mods offer the best balance of power, flexibility, and performance.
Understanding Wattage and Power Output
Wattage is one of the most important factors to consider when choosing a box mod. It determines how much power is delivered to your coil, directly affecting vapour production, throat hit, and flavour intensity.
What Is Wattage in Vaping?
Wattage (measured in watts, or W) controls how much power your mod sends to the coil. Higher wattage produces more heat, which increases vapour production and flavour intensity. Lower wattage provides cooler vapour, longer coil life, and better battery efficiency.
Wattage Ranges Explained
Low Wattage (10W-30W):
- Best for MTL vaping and high-resistance coils
- Produces minimal vapour
- Ideal for nicotine salts and 50/50 e-liquids
- Extends battery life significantly
Medium Wattage (30W-60W):
- Suitable for RDL vaping
- Balanced vapour and flavour
- Works with most standard sub-ohm tanks
- Good all-day vaping range
High Wattage (60W-100W):
- Designed for DTL vaping and cloud production
- Requires low-resistance coils (0.2Ω-0.5Ω)
- Uses high-VG e-liquids for best results
- Drains batteries faster but delivers intense flavour
Very High Wattage (100W-200W+):
- Built for advanced cloud chasing
- Requires dual-battery mods for consistent power
- Best with rebuildable atomizers or high-performance tanks
- Produces massive vapour clouds
How to Choose the Right Wattage
Start by checking the recommended wattage printed on your coil. Begin at the lower end of the range and gradually increase until you find your preferred balance of flavour, warmth, and vapour. Running your mod too high can burn coils quickly, while running too low produces weak flavour and vapour. Most vapers find their sweet spot between 40W and 80W for everyday sub-ohm vaping.
Box Mod Vaping Modes Explained
Modern box mods offer multiple vaping modes, giving you complete control over how your device performs.
Understanding these modes helps you get the most out of your mod and improves coil lifespan, flavour, and overall satisfaction.
Variable Wattage is the most commonly used mode, allowing you to manually set the power output.
How it works: You choose the wattage, and the mod delivers consistent power to the coil regardless of battery charge.
Best for:
- Everyday vaping
- Adjusting vapour production and warmth
- Most sub-ohm tanks and coils
Why vapers use VW mode:
- Simple and straightforward
- Works with all standard coils
- Easy to adjust on the fly
Temperature Control lets you set a maximum temperature for your coil, preventing dry hits and burnt taste.
How it works: The mod monitors coil temperature and reduces power automatically to stay within your set limit.
Best for:
- Advanced users
- Rebuildable atomizers with stainless steel, nickel or titanium coils
- Preventing burnt hits
Why vapers use TC mode:
- Protects against dry hits
- Extends coil lifespan
Bypass mode turns your box mod into a mechanical-style device, delivering power directly from the battery without regulation.
How it works: Voltage output depends entirely on battery charge, just like a mech mod, but with safety protections intact.
Best for:
- Experienced vapers who want a raw vaping experience
- Users familiar with Ohm's Law
- Rebuildable atomizers
Why vapers use bypass mode:
- Simpler, direct power delivery
- No wattage or voltage limits
- Mimics mechanical mod performance with added safety
Variable Voltage mode lets you control the voltage sent to the coil rather than the wattage.
How it works: You set the voltage, and the mod adjusts power based on coil resistance.
Best for:
- Vapers who prefer fine-tuning voltage over wattage
- Advanced users experimenting with different coil builds
Why vapers use VV mode:
- More precise control over power delivery
- Useful for custom coil builds
Curve mode allows you to create a custom power curve, adjusting wattage at different stages of your puff.
How it works: You set different wattage levels for the beginning, middle, and end of each inhale.
Best for:
- Advanced users who want ultimate customisation
- Optimising flavour and vapour production
Why vapers use curve mode:
- Tailors the vaping experience to personal preference
- Prevents overheating at the end of a long draw
Most vapers stick with Variable Wattage for everyday use, but having access to TC, Bypass, and Curve modes gives you flexibility as your experience grows.
Auto Mode, sometimes called Smart Mode, automatically sets the power for you based on the coil you are using.
How it works: The mod detects the coil resistance, then selects a wattage within the recommended range and may limit the maximum power to keep things safe.
Best for:
- Newer vapers who are unsure what wattage to pick
- Quick setup when changing tanks or coils
- Prefilled coils with a printed wattage range
Why vapers use Auto Mode:
- Removes guesswork when choosing power
- Helps prevent burnt coils from too much wattage
- Gives a consistent vape when swapping coils or e liquids
- Ideal for anyone who wants an easy, hassle free experience
