ChongDianTou did a comprehensive teardown of Switch 2 charger NGN-001, including the Type G and Type A versions. Aside from the plug, logo location (img 1 below), and a time-delay fuse (img 2), they are otherwise identical (img 3).
One interesting detail: The Weltrend WT6633P controller supports Qualcomm Quick Charge 5. If you have a Snapdragon device capable of QC 5, NGN-001 may charge your device faster than a standard USB PD charger.
Although there are two manufacturers for the charger, Delta and Lite-On, supply chain news from Taiwan suggests that Weltrend supplies the controller to both. So chargers made by either companies should work the same.
