The 16A charges fast, the 10A is too slow.
The charging time of new energy vehicles is related to the 10a and 16a plugs used. Slow charging is the safest and most conventional way to charge electric vehicles, that is, AC charging, and the charging process generally takes 6-8 hours.
The car charger sent by the car is a 10A plug, the actual charging power is only about 1.4kW, that is to say, an hour to charge 1.4 degrees of electricity, the speed is quite slow.
The 16A is faster.
The difference in charging current between the two is that one belongs to fast charging and one is conventional charging. Tesla charging current 10a, belongs to the conventional charging, its charging rate is relatively slow, but its charging effect is better. 16a charging, using a fast charging method, can be fully charged in a short period of time. The main difference between the two is the speed of charging.
