  • Connect USB-A and USB-C devices at the same time
  • 10 Gbps data rate with USB 3.1 Gen1/Gen2 compliance

USB-C 3.1 Charging Bridge 10 Gbps

The LORDWORLD JCH349 connects a USB Type-A device to a USB-C host while passing through Power Delivery. It suits owners of MacBook, Chromebook or XPS 13 and 15 models who need legacy peripheral support without losing charging capability. The adapter handles USB 3.1 Gen1 and Gen2 traffic at up to 10 Gbps.

Plug-and-play installation

No drivers are required; the bridge is hot-swap compatible and works immediately on supported hosts. Backward compatibility with USB 3.0, 2.0 and 1.1 ensures older peripherals still function. The only common issue arises when a connected Type-A device draws more current than the host port can supply.

Sustained 10 Gbps throughput

Under continuous load the bridge maintains the full 10 Gbps signalling rate defined by USB 3.1 Gen2. Power Delivery remains active during long transfers so the host battery does not drain. Thermal throttling is not observed because the unit has no active cooling and relies on passive heat dissipation.

Questions about this item

How can I confirm the JCH349 is delivering 10 Gbps throughput after plugging it in?

Connect a USB 3.1 Gen2 storage device and run a benchmark; sustained reads near 10 Gbps indicate the bridge is operating at full spec.

What cables or adapters must I supply besides the JCH349 unit itself?

You need a USB-C host cable with Power Delivery support and any USB-A peripheral cable; the bridge only provides the female USB-A and USB-C ports.

Should I choose this 349 model for a MacBook 13 or an XPS 15?

The JCH349 works with both 13 and 15 inch USB-C laptops that support Power Delivery and USB 3.1 Gen1/Gen2.
