Hi Waverley,
Your new T03 should have a cable for tethered charging and a UK 3 pin granny charger
Personally, I've only ever charged via granny charger but never used the supplied T03 charger as I found the overall cable to be shorter than I need and the electronics block is about the middle of the length of cable
Due to this, I bought an evdance granny charger as the electronics block is much closer to the 3 pin plug and the overall length is around 10 meters
Evdance charger has a basic control to select different amps up to 13 - I think leapmotor goes to 10
Evdance also has a meter which displays charger running time and kwh delivered - there is a small amount of energy inefficiencies between energy delivered and energy plonked into the battery as stated by the car
My evdance charging cable goes out my window and straight into the car
