A 65W USB-C power adapter compatible with numerous Dell XPS, Latitude and Chromebook models
This 65W USB-C AC adapter supplies power to a wide range of Dell XPS, Latitude and Chromebook models. It accepts 100-240V input at 50/60Hz and delivers 5V, 9V, 15V or 20V output through a USB Type-C connector. The unit replaces original Dell part numbers such as LA65NM170, LA65NM190 and DA65NM190. It is intended for users who need a direct replacement for a lost or damaged Dell USB-C charger.
The adapter covers Dell part numbers rated at 45W and 30W including LA45NM150, LA45NM171, DA30NM150, HA30NM150 and AA45NM150. Moving from a lower-wattage brick to this 65W unit is worthwhile when the laptop draws more power under load or charges slowly with the smaller adapter. It will not help if the device firmware limits input to the original wattage or if the barrel-connector port is the only charging path.
The charger provides fixed output profiles of 5V/3A, 9V/3A, 15V/3A and 20V/3.25A and does not support programmable voltage steps outside these values. Laptops that require a higher current at 20V or a proprietary charging handshake will not charge at full speed. The USB Type-C connector fits physically but cannot overcome protocol mismatches or missing Power Delivery negotiations.

Yes, the adapter uses a USB Type-C connector rated for 20V/3.25A output and matches Dell part numbers LA65NM170 and 02YK0F listed for those models.
Plug the IEC power cord into the adapter first, then into the wall outlet, and finally insert the USB-C plug into the laptop; reversing the sequence can prevent the charger from negotiating 65W.
Replace the unit if the USB-C cable shows exposed wires, the connector feels loose in the port, or the adapter no longer delivers 20V/3.25A under load.
