Photo → diagnosis AI reads the photo, matches 50 common EV faults in Vietnam, returns a report + repair guide. Will extras kill the battery? Lights, a charger, bar gadgets — can idle charging still feed them? Is the shop padding the bill? Type the kilometres. See what’s actually due and a fair Vietnam price — take it to the shop. How long until the phone cooks? 38°C, Maps open, maybe charging — minutes before dim / shutdown.
