Travel Adapter Kit

A basic multi-plug travel adapter kit (China, 500-unit run) lands around $3–6; a single-port USB-C wall charger runs $2–4; a multi-port high-wattage charger runs $6–12.

An adapter only changes the physical plug shape to fit a foreign socket and does not alter voltage; a voltage converter is a separate, heavier device that actually steps voltage up or down, needed for devices not rated for the destination country's voltage.

20W for standard phone fast-charging; 65W or higher for laptop charging capability. State the target device type, since a phone-rated charger will charge a laptop far more slowly.

Typically 500–1,000 units per design, since the internal electronics and safety certification testing both carry fixed costs that need volume to justify.

Total wattage is shared across all active ports, so plugging in multiple devices simultaneously reduces the charging speed each one receives compared to using a single port alone.

Requirements vary by destination country (e.g., UL in the US, CE in the EU, CCC in China) and are mandatory for legal sale — confirm the specific certification needed for each target market before sourcing.

These generally fall under HS 8504 (electrical transformers and static converters). Confirm the specific subheading based on power rating, and note that some markets require additional safety documentation for import.
