Faster Charger for F2 Pro

I understand that the OEM charger is 1.7 amps, and I’ve been told that the max charge the scooter allows is 2 amps.

But I read somewhere else that ninebot may have raised the maximum charging amps to 3.

Has anyone found a faster charger to use with this scooter? Even 3 A would be much better than 1.7.
