Dell A1706 65W Charger for Surface

This DELL A1706 adapter delivers 65W at 15V 4A through a magnetic Surface connector for Microsoft Surface Pro, Laptop, Go and Book models. A USB-A port supplies 5V 1A to charge a phone or accessory at the same time.

Sustained load with magnetic connector

The unit maintains continuous 15V 4A output with built-in overheating, overload and short-circuit protection and CE certification. The corded electric design keeps the connector stable during long charging sessions.

Practical limits of 15V 4A interface

Output is fixed at 15 volts and 4 amps, so devices needing 20V or higher current will not charge from this adapter. Buyers who need 85W or 20V 11.8A operation should select a different power supply.
