LORDWORLD SF531 Magnetic Adapter for Surface

The LORDWORLD SF531 is a magnetic adapter that adds USB 3.1 Type-A and USB-C ports to compatible Surface devices. It draws power through the Surface magnetic connector and requires an attached charger to operate the USB 3.0 port. Data transmission works on one side of the magnetic port only. The adapter supports USB 3.0 Super-Speed at 10 or 5 Gbps, USB 2.0 Hi-Speed at 480 Mbps, and USB 1.1 Low-Speed at 1.5 Mbps.

Suits Surface owners needing extra ports

This adapter suits owners of Surface Pro 9, Pro 8, Pro 7, Pro 6, Pro X, Go or Book models who want to connect SSDs, keyboards, mice, hubs or other Type-C peripherals. It is not for users who need dual-side data transmission through the magnetic connector. It is also not for anyone wanting to run the USB 3.0 port without a separate charger connected, because the magnetic port supplies no external power output.

Check Surface model and charger compatibility

Before ordering, verify that your Surface model appears in the supported list above. Confirm you have a compatible charger that can deliver 45 W at 15 V 3 A through the adapter's USB-C female port, which contains a built-in PD emulator trigger. Ensure you only need single-side data transfer, as the magnetic port does not transmit data on both sides.

Questions about this item

Does the SF531 magnetic adapter need an external charger connected to power the USB 3.1 Type-A port?

Yes, the magnetic port does not supply external power, so a charger must be connected to the USB-C PD port before the Type-A port can operate.

Will the SF531 work with a Surface Pro 6 that still uses the original magnetic charging connector?

The adapter fits the magnetic connector used on Surface Pro 9, 8, 7, 6, Pro X, Go and Book models, allowing USB-C and USB-A peripherals on those devices.

How can I confirm the SF531 is delivering 45 W at 15 V after plugging it in?

The USB-C female end contains a built-in PD emulator trigger that negotiates 45 W (15 V 3 A) when a compatible charger is attached.
