Dell chargers only work (reliably, and at capacity) with Dell devices. Also Dell devices will (sometimes) refuse to work with 3rd party chargers. Get a charger that displays the voltage & current being output on a port and you will quickly see what devices adhere to standards. The USC-C port doesn't guarantee compatibility. Manufacturers are being evil and pushing proprietary protocols over open standards.
