This adapter does not meet specifications: it does not support even a load of 0.9A and 0.7A even The first one I received worked for 15 minutes on a 12V 0.9A LED lamp. and finally adopted! dialogue with Skybear was laborious, in English, and obviously my interlocutor had problems understanding. After 3 round-trip emails, I received the same diet. it did not take more than 5 minutes on a 12V 0.7A load. I am an electronics and circuit of these power supplies, which I analyzed, is very basic and does not include any protection. Stay away absolutely!
