Using a fast charger XM4

[STUART1978]

I have a fast charger (UGreen GaN X 65w) to charge my phone. Can I safely charge my WH-1000XM4s using said fast charger without doing damage?

Hey @STUART1978, I think it would damage the battery or reduce its life. You can use the supplied cable with any AC adaptor.
