USB Power Delivery Limits

The adapter negotiates power through USB Power Delivery at 5V/3A, 9V/3A, 15V/3A and 20V/4.5A. It accepts a universal 100V-240V input at 1.5A, 50-60Hz. Maximum output is capped at 90W, so devices requiring higher fixed voltage or current will not draw full power from this unit.

90W Capacity and Headroom

At 90W the adapter comfortably handles 29W, 30W, 45W and 65W Dell systems without overheating.

Buyers needing power for higher-wattage configurations should verify their device specification before purchase.
