Mobile Phone Charger Compatibility Checker
Wondering if your 65W or 100W laptop charger is safe for your phone, or why your Samsung isn't showing "Super Fast Charging"? Test any phone and charger combination instantly.
Select Phone / Device Standard:
Charger Brick in Hand
Compatible (Peak Fast Charging)
The charger is compatible. The phone will negotiate power and draw its maximum peak rate (~30W) to charge at full speed.
🔥 Will a 100W Laptop Charger "Overcharge" or Damage My Phone?
NO! Absolutely not. USB-C Power Delivery uses active bidirectional negotiation. The charger cannot "push" 100W into your phone. The phone's internal battery management system (BMS) requests exactly what it can safely handle (e.g. 27W for an iPhone 16 Pro, 45W for a Galaxy Ultra).
