This OEM NIU Standard Battery Charger is compatible with NIU 60V 26Ah/29Ah/35Ah batteries found in NQi Sport and NQi GT/S scooters. This is the standard charger that'll power up your NQi Sport in about 7 hours. The NQi GT/S ships with a faster charger, but this standard charger will work; it'll just take a little longer because you're charging two batteries instead of one.
