Mine is wp 400 and when I charge it I don’t see any light how can I now that it’s enough?

I have charged this thing for days and it will not power on at all. There are no lights to show that it is charging and no power to it. It leaks really bad also

Eu tenho do outro modelo, a pressão e ótima, é uma pena que é caro e não dura muito, e não conheço ninguém que concerta esse aparelho, quando quebra tem que jogar fora🤦😔
