The V2L output standard for domestic models in China is 220V/50Hz. If your country's power grid standard is 110V/60Hz (like in some parts of North America), you cannot directly power local high-power appliances and will need an external transformer.

It depends on the specific brand and model. Some brands (like BYD and MG) have native multilingual systems that can switch to English directly; however, some models designed for the Chinese domestic market only have a Chinese interface. For systems that only have Chinese, we can assist with compliant system flashing (installing international firmware) or adding modules that support Apple CarPlay/Android Auto, so you can use Google Maps. The details page will clearly indicate the language status of each vehicle's system.

For gasoline cars, insist on a compression test: each cylinder should read within 10-15% of the others, and the actual values should match factory specs for that engine. A single low cylinder points to worn rings or valve problems that idle checks will never reveal. A leak-down test goes further. It pressurizes each cylinder and measures how much air escapes and where. Air hissing from the oil filler cap means ring wear; from the intake or exhaust means valve issues; bubbles in the radiator coolant mean a head gasket problem. This is the single most revealing test for engine condition. Also request OBD scan data with freeze-frame records, a coolant system pressure test (to catch hidden leaks), and an inspection of the timing belt or chain condition with service history. For electric vehicles, compression tests don't apply — instead ask for a battery health report from the BMS, motor insulation readings, and a road test logging any inverter or drive-unit fault codes. A written report with photos or video of each test is essential evidence for your records.
