⚡ What is a 5V Heating System?
The 5V heating system uses USB or power bank power supply to generate low-voltage resistance heating.
It is designed for lightweight daily wear where convenience is more important than extreme heating power.
Key Features:
- USB / power bank powered
- Lightweight heat output
- Longer runtime in mild weather
- Simple daily-use system
Best Use Cases:
- Daily commuting
- Indoor / office use
- Mild winter conditions
🔥 What is a 7.4V Heating System?
The 7.4V system uses dual lithium battery packs to deliver higher power output and faster heating performance.
It is the standard system for professional heated gloves and outdoor heating gear.
Key Features:
- High heat output
- Faster warming speed
- Stable performance in sub-zero environments
- Professional outdoor-grade system
Best Use Cases:
- Skiing & snow sports
- Outdoor work
- Extreme cold (-10°C to -30°C)
🆚 5V vs 7.4V Comparison
| Feature | 5V System | 7.4V System |
|---|---|---|
| Heat Output | Moderate | High |
| Heating Speed | Slower | Faster |
| Power Source | USB / Power Bank | Lithium Battery |
| Usage | Daily life | Outdoor |
🧠 How Heating Technology Works
Both systems use resistance heating based on:
👉 Joule Heating Principle (P = I²R)
Performance depends on:
- Voltage level
- Current stability
- Heating material (carbon fiber / composite fibers)
