I cannot confirm with certainty the compatibility of the "ADAPTATEUR.AC.65W.1.1x3.0x7.7.BLA (65 W)" adapter with the Acer Spin 3 SP314-54N-72W6 model. However, the adapter is designed for Acer laptops and has a power rating of 65 W, which could be compatible with many Acer models, including those in the Spin 3 series. For definitive confirmation, I recommend you check the official model specifications or contact Acer customer service.
