I've just received this adapter to transfer some information from a 2010 Macbook air SSD (and as a handy back-up tool just in case.) The instructions however, are in Chinese. They involve a jumper setting which enables (or disables) a voltage regulator (I think) marked with 1084-33 APL GH50U or some such. If anyone can help with the translation, it would be much appreciated. (I trust this is the correct sub-forum.) Thanks in advance.
