Simple Solution for Using USB-A Cables with USB-C Chargers
I used these for the first time last week when I needed to plug a USB-A cable into a newer USB-C charger.
They worked exactly as expected. The connection was solid, and the device powered on without any issues.
I’ve generally had good experiences with Anker products, and these adapters are consistent with that—simple and reliable for what they’re designed to do.
These are useful for bridging older USB-A cables with newer USB-C power sources, especially for basic charging needs.
Build quality feels solid for the size, and they’re small enough to keep with your cables without getting in the way.
Overall: a straightforward and reliable adapter for using USB-A cables with USB-C chargers.

Great product, mic and camera compatible
I bought this to use a webcam with a built-in mic on my Microsoft Windows Surface Pro 8. When I first plugged in the webcam both the camera and the mic were recognized, however the mic was not picking up sound. After double checking the device settings, my privacy settings, the device drivers, and everything else I simply unplugged and replugged the camera in. Then everything worked as I had hoped. Great value for a great product. I trust Anker to reliably protect and provide stability for all of my devices. Simple product, plug and play. Sleek, simple design

Great piece of equipment. Worked for mouse, hard drive, and digital camera all into a laptop.
Works great. I used to plug in a mouse, an external hard drive, and an overhead Nikon digital camera for historic digitization of documents and books. It small and compatible and there were no connection or power problems. It feels well built and sturdy and the cord connection to the device is strong and flexible.
