After a long market research, I decided to buy this adapter that replaces the original one. Certainly it is more cumbersome (11,5x5x3 against 8,5x3,5x2,5, cm) and a bit heavier but the connector is well suited to an Asus 1015 PN and the subjective quality of materials is good. The cable length is satisfactory (about 1.20 m and 1.60 m line side PC side) and moderately warm. This product deserves 4 stars and not 5, for now, because, in my opinion, the fifth star is related to its life on which I can not yet say.
