Acer KP.13501.008 is a 135 W AC adapter for powering a compatible Acer computer from a wall outlet. Its 19.5 V rated output and the listed compatibility with the A715-74G help identify whether it matches your setup.
The adapter has a black slim-type design and an X-pin connector with a purple tip, measuring 1.7 × 5.5 × 11 mm. Check the tip and dimensions when matching it to an existing adapter, since Acer models can use different connectors.
It can serve as a replacement for a matching adapter or as an additional power source for a compatible setup. The listed model reference is the Acer A715-74G; compatibility beyond that model is not specified.
Package contents: one power cord is listed with the adapter.
