The 65W output enables fast charging for most phones and gaming handhelds

At 65W, the output exceeds most chargers in this price range, capable of charging any phone or gaming handheld even during use. It maxes out the charging rate for devices like the Nintendo Switch and Switch 2 (18W-20W), Steam Deck (35W), and Asus ROG Ally (65W). Newer models such as the Asus ROG Ally X and Lenovo Legion Go support up to 100W, but using 65W is recommended to maximize battery lifespan. In fact, these handhelds ship with official 65W chargers.
