Replacement USB-C Power Adapter

This 45W USB-C AC adapter replaces the original Dell charger for compatible laptops. It accepts AC 100-240V input at 50/60Hz for worldwide use. The unit includes OVP, OCP and SCP protection against overvoltage, overcurrent and short circuits. Buyers who need a higher-wattage supply for larger laptops should look elsewhere.

Critical Compatibility Check

The adapter matches Dell part numbers 689C4, 492-BBUU, LA45NM150 and 8XTW5. Verify that your device lists one of these exact codes before ordering. Using an incorrect charger can prevent charging or damage the laptop. This unit is not for owners of Dell models that require a different connector or power rating.

Sustained Load Behaviour

Safety mechanisms monitor output continuously during extended charging sessions. Overvoltage, overcurrent and short-circuit protections engage automatically if limits are exceeded. Internal overheating protection reduces risk during prolonged operation at full 45W output. The adapter maintains stable delivery without thermal throttling under normal conditions.
