旅行设备和保护
Choose carry-on luggage for the journey, not the showroom
Compare cabin dimensions, wheels, handles, weight, layout, repairability and airline rules through a real packing test.
Choose a universal travel adapter without confusing plug shape and voltage
Check destination sockets, input voltage, power limits, grounding, USB charging and safety certification.
Compare cross-border warranty and return protection before buying
Check seller identity, return address, statutory rights, warranty territory, shipping responsibility and payment evidence.
