Product is ok but very very slow shipping. More than half and a month delayed. Very unsatisfied. Do not trust the delivery time given by the seller.
Seems to be working fine, the output is 42,2V and my scooter draws 1,5A. That would mean the charger is a bit slower than the stock Xiaomi charger. On the other hand it is a little smaller. Great as a second charger to leave at work.
