Technical Breakdown
Anker’s Efficiency Secrets
- GaNPrime chip dynamically allocates power
- Zero Voltage Switching cuts switching loss
- Standby power 78% below ENERGY STAR
Belkin’s Power Drain:
- Silicon MOSFETs have higher conversion loss
- Independent circuits increase standby waste
- Heat sink mass causes thermal retention
