|You forget to list whether the adapter is AC or DC out. If DC, is it negative or positive tip? Even if the adapters are same AC/DC-wise and the tip polarity is correct, it's never a good idea to go much above (5%) the stated voltage (16 vs 19.6 is a 22.5% difference), especially for something like a laptop. The charge circuit could easily be damaged (as you suspect).|
