When verifying the overseas warranty for portable charging equipment, first ask who issues the equipment brand, serial numbers and applicable markets, then confirm that warranty provider and coverage and fault testing, replacement and installation responsibility cover the full order. Spell out the brand, serial numbers, applicable regions, testing method, replacement and installation responsibility in the warranty — do not fold it into the vehicle warranty with a single sentence.
Record the serial number of each charging unit separately; the vehicle VIN and the equipment number cannot be merged into a single warranty.

The charging equipment warranty is ultimately governed by the local rules and written confirmations in force at the time of processing.
