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

Simple and not Drama claim process.

’ve had Asurion coverage for a couple of years and never needed to use it until recently, when my pool salt cell (less than two years old) stopped working. I had purchased it with an Asurion protection plan, so I contacted them to start a claim. The process was simple and straightforward to follow. In the end, they honored the plan and covered the cost of my salt cell based on the value when I originally bought it. They issued me a gift card that I could use on Amazon for that amount. While prices have gone up and a new cell now costs about $200 more, it was still definitely worth having the coverage. Overall, I’m satisfied with how the claim was handled.
