1. Advanced GaN Technology in Car Chargers
Traditional car chargers overheat at 60W. Our GaN-powered car adapters handle up to 100W-140W output while maintaining a cool exterior—perfectly safe for long-distance driving.
The GaN Advantage
Cool Operation at High Power
GaN technology reduces heat generation by 30% compared to traditional silicon chargers, enabling sustained 100W+ output without thermal throttling.
Compact & Lightweight
GaN V technology allows us to shrink the charger size by 40% while maintaining full power output. Our flagship models weigh under 50g.
Integrated OTP Protection
Over-Temperature Protection keeps it safe even in summer heat. This feature comes from our high-end GaN chargers.

2. Engineering for Stability: The Anti-Slip Design
A charger is useless if it falls out on bumpy roads. We use reinforced springs to ensure constant contact in all vehicle types.
Physical Stability
- Non-slip Shrapnel: Reinforced contact points for 12V-24V sockets
- High-Tension Springs: Maintains contact during bumps and accelerations
- 3000+ Plug/Unplug Cycles: Tested for commercial fleet durability
- Low-Profile Design: Sits flush with cigarette lighter, won't snag on bags
Premium Materials
- Aluminum Alloy Shell: Superior heat dissipation and premium feel
- V0 Fire-Retardant PC: Highest fire safety rating for automotive applications
- 24-Hour Salt Spray Test: Anti-corrosion protection for all climates
- UV-Resistant: Won't fade or crack in parked vehicles
