❓ 6. Frequently Asked Questions
Common Doubts Clarified
Essential questions about GaN charger technology and practical usage
Q: Do GaN chargers charge faster?
A:
Yes, with proper device support (USB-C PD/PPS). The speed improvement comes from better power delivery protocols, not just the GaN technology itself.
Q: Can I replace my laptop charger with GaN?
A:
Yes, if the wattage matches and the charger is certified. Check your laptop's power requirements (usually 45W-100W) and ensure the GaN charger supports that output.
Q: Are GaN chargers safe?
A:
Yes, when BIS-certified and from reputed brands. GaN technology itself is safe and provides better thermal management than silicon chargers.
Q: Will GaN chargers work with my old devices?
A:
Most GaN chargers are backward compatible, but you may need appropriate cables. USB-C to Lightning for iPhones, or USB-C to Micro-USB for older Android devices.
Q: How much should I pay for a good GaN charger?
A:
₹2,000-4,000 for 65W models, ₹3,000-6,000 for 100W models from reputed brands. Avoid unknown brands under ₹1,500 as they may lack proper safety features.
🎯 Key Takeaway
GaN chargers offer real benefits for multi-device users and travelers. Choose certified brands, match wattage to your devices, and expect to pay 20-40% more for the convenience.
