The ¥1,255 Type-C Magnetic Conversion Adapter adds a quick-release magnetic connection while supporting up to 240W charging, 40Gbps data and 8K video at 60Hz.
Sanwa Supply has launched a magnetic USB-C conversion adapter that lets users turn an existing Type-C cable into a quick-release connection, reducing the need to repeatedly plug and unplug the lead from a device. The company said the new accessory, sold through its Sanwa Direct online shop, is intended to make everyday charging and connection use simpler while helping to reduce wear on the device port.
Branded as the Type-C Magnetic Conversion Adapter, model 500-USB110BK, the product is designed to stay attached to the port on a smartphone, laptop or similar device. The cable then snaps into place magnetically, which means the user can connect it with a single motion. Sanwa Supply says that this approach can ease strain on the port itself and may help reduce damage caused by frequent insertion and removal over time.
The company also claims the adapter is built to handle demanding modern USB-C use. It supports USB Power Delivery at up to 240W, which places it in the class of accessories suitable not only for phones and tablets but also for higher-power laptops. It is also rated for data transfer speeds of up to 40Gbps and video output at up to 8K resolution at 60Hz, making it compatible in principle with high-speed storage, docking use and external displays.
That specification set places it in line with a wider category of premium USB4 and USB-C accessories now appearing across the market. Comparable products listed by other retailers also combine 40Gbps data transfer, 240W charging and 8K/60Hz video support, suggesting that magnetic and high-spec USB-C adapters are becoming a more established niche for users who want both convenience and full-performance connectivity. Sanwa Supply is selling the adapter through its own store as well as major marketplace channels, with a tax-excluded price of ¥1,255.
