Review on Genuine Dell 130W Laptop Charger AC Adapter 332-1829: Optimized Power Supply for Precision M3800, M2800, XPS 15 (9530, 9550), Inspiron 7347, 7348, 7459 - Dell Charger 130W AC Adapter+ by Diztymewntu Sacra

Identical to the one that came with my XPS 9570. The pen end of my original was deformed by bending. The 9570 no longer recognized the performance of the adapter. This adapter is an exact replacement and now my laptop is working (and charging) again. I should note that when the laptop boots up, the BIOS still gave a warning that the adapter was not recognized and the computer was not charging. However, I ran a system diagnostics test that cleared the trouble code. Since then everything has been going as usual.
