Compact USB-C to USB-A adapter pair

The XAOSUN OTG-R two-pack converts a USB-C female port to a USB-A male plug for charging and data on laptops, phones or headsets. Gray aluminium shells measure 1.34 x 0.53 x 0.26 in and weigh 0.77 oz each. Rated for 10 Gbps transfer and 100 W power delivery.

Flip-to-fit orientation and durability

Single-sided USB 3.1 Gen 2 contacts mean the Type-C plug must face the correct way for 10 Gbps speed; flipping it drops the link to USB 2.0. Integral aluminium housing survives 20000 insertions. Dual 56 kΩ pull-up resistors enable safe 5 A charging.

Protocol and power limits

USB-A host ports cannot negotiate Power Delivery, so 100 W charging only works with compatible source devices and cables. The adapter does not support PD after USB-A conversion and will not charge a MacBook or 12 W MagSafe charger. Maximum throughput stays at 10 Gbps.

Questions about this item

How do I confirm the adapter is delivering 10Gbps speeds after plugging it in?

Transfer a large file between connected devices and verify the transfer rate approaches 10Gbps; the single-sided design means you may need to flip the Type-C plug to engage the higher-speed lane.

What comes in the package and do I need any extra cables?

The 2-pack includes two gray USB-C female to USB-A male adapters; you only need your existing USB-C cables or devices to plug into the female ports.

Which version should I choose if I want 100W charging for a laptop?

This OTG-R model supports up to 100W 20V 5A charging, but note it does not carry Power Delivery through the USB-A end, so it will not charge a MacBook or 12W MagSafe charger.
