Power Cord Factory & Supplier in the Tokyo Market

We maintain full manufacturing controls aligned with Japan's DENAN Law. For power cord assemblies, plugs, and specified electrical appliances (Category A), we manufacture strictly to meet Diamond PSE criteria through authorized third-party conformity testing (such as JET or TÜV Rheinland). For non-specified electrical appliances like multi-tap power strips (Category B), we provide the technical construction files, self-declaration testing protocols, and Circle PSE conformity documentation required by the Ministry of Economy, Trade and Industry (METI).

Our factory is located in Guanhaiwei Town, Cixi, Ningbo—situated adjacent to Ningbo-Zhoushan Port, one of the world's most active container transshipment hubs. For standard OEM production runs, our average lead time is 25 to 35 days post-sample approval. Maritime transit from Ningbo Port to the Port of Tokyo or Port of Yokohama takes merely 2 to 4 days via direct container feeder lines, offering Tokyo importers an exceptionally agile, low-lead-time supply chain compared to inland manufacturers.

Yes. With 20+ years of dedicated OEM/ODM experience and in-house mold-making capabilities, we can execute custom enclosure tooling, pad printing, engraved branding, and customized cord length configurations. Furthermore, our pre-press design team regularly works with Japanese corporate clients to develop localized packaging conforming strictly to Japanese Consumer Affairs Agency labeling standards, including JAN barcodes, precise Japanese warning copy, and eco-friendly blister-free packaging.

Every individual power strip and cable reel passes through automated 100% testing on our assembly lines, including continuity testing, polarity checking, dielectric withstand (Hi-Pot) testing at 2,000V AC, and insulation resistance verification (>5MΩ at 500V DC). Additionally, lot-based mechanical testing is performed in our in-house lab: plug withdrawal force testing, cable flex resistance (bending test), flame-retardant burn chambers, and temperature-rise testing under continuous maximum rated ampacity.

Our MOQ structure is designed to support both agile product testing and high-volume commercial programs. Compact travel adapters and wall plug units start at MOQs as low as 50 to 500 units for standard colors. Industrial cable reels generally require an MOQ of 100 to 500 units, while customized multi-outlet power strips with client-specific tooling or localized silk-screened logos start at 1,000 to 2,000 units per production run.

Unlike sourcing agents or trading brokers, Cixi City Fenvo Technology Co., Ltd. is an actual manufacturing plant established in 1995 with 4,587 square meters of physical workshop space, 4 specialized production lines, and an on-site verified audit status by TÜV Rheinland. We own our injection molding equipment, contact punching dies, and wire winding automation. This direct engineering control guarantees full bill-of-materials transparency, stable pricing without broker markups, and uncompromised material consistency.
