It works for my purpose but not sure if working as described. It only seems to output 15 volts (photos 1) while my other charger with the same specs will output the full 20 (20.3?) volt (picture 2) that the laptop is capable of. Pictures taken swapping back and forth with lots of time to adjust and laptop at the same (within minutes) state of charge. It claimed to be capable of 20v/1.5a but I have never seen it do that. Is it the negotiation part or the capability part? It is almost half the size of the one doing 20v so I suspect it is just over sold. Overall it charges at almost the same total watts so I find it acceptable.

Fonctionne très bien pour alimenter un macbook air

they work like and better than the big brands

We have been replacing original chargers with these for a whilw and had no problems

Perfectly fine charger.

pretty good
