A:Answer A USB-C compliant charger is needed to achieve the fastest charge possible for the GBX. The U65 is the NOCO brand fast charger.
Non-NOCO chargers must exactly match the USB-C compliant specs listed below for the fastest charge:
5V @ 3A (15W)
9V @ 3A (27W)
12V @ 3A (36W)
15V @ 3A (45W)
20V @ 3A (60W) - Fast Charge LED illuminated
If the charger does not follow the standards above, even if it is branded as a ""fast charger,"" the GBX will default to charging at 5V and a slower charge rate.
