Dell DA45NM131/LA45NM131 45W Slim Laptop Charger USB-C

The Dell DA45NM131/LA45NM131 is a slim 45-watt power adapter designed to charge Dell's ultrabook and thin-and-light laptop lines via USB Type-C. As a genuine Dell adapter, it communicates with compatible laptops through proper USB-C Power Delivery negotiation, delivering 5V or 20V at up to 2.25A to match the device's charging requirements. This ensures stable, safe charging without the compatibility concerns that can arise with third-party USB-C chargers on Dell systems that use Dell's proprietary handshake protocol.

The slim form factor is the adapter's standout physical feature — it is noticeably thinner and lighter than Dell's standard rectangular 45W chargers, making it a strong choice as a travel adapter or secondary charger for home use. The included power cord connects to a standard wall outlet, and the USB-C tip plugs directly into the laptop's charging port with the convenience of a reversible connector. Compatible models span several generations of Dell XPS 12 and 13, Latitude 2-in-1s, and select Inspiron and Vostro lines. Buyers should check the part number on the back of their current adapter or verify their laptop model number against the compatibility list before ordering to ensure a proper match.
