No, more is not possible. But that's a good thing, because the matching socket is almost certainly not designed for 10A continuous current. In our case, it was even difficult with 8A due to the narrow cable cross-sections installed, so I had to reduce it to 6A. It just takes time...

The set (T13, CEE32 red) comes with an overtemperature-protected T12 adapter. Since all the plugs at Juice are coded and transmit the maximum load capacity to the charging station, it is not possible to set the charger to >8A with the T12 adapter.
