Review on JSAUX Aluminum Connector Keychain Compatible by Bob Jensen

When I'm in my backpack I carry 2 charging cables - Micro-USB for camera and GPS and USB-C for Samsung phone. I'm a gram freak so I picked these up to carry around with just a cable and this little adapter. Expecting them not to support USB 3.0 fast charging, I didn't care as I just wanted to save a few grams while still charging my devices overnight. I am not at all disappointed with these adapters. They have worked great on my power banks to charge the above devices. My biggest concern has been the charging time of my Samsung phone, but I haven't noticed any slowdown in charging time when using this adapter via a good quality micro USB cable. I'm pretty impressed, actually. The female end fits snugly onto the micro USB cable and stays strong. The USB C connector is also great for my Samsung S8, even with the large, bulky housing. The adapters are slim and sturdy and come with a small carabiner keychain that attaches directly to the cable so you don't lose it. A great idea. I have not yet tested these adapters in data transmission. Based on the loading time, I would expect the data transfer to work fine, but if I have any issues with it I'll update this review. So now all I have is 1 micro USB cable and this adapter and I can charge whatever electronics I carry around without noticeably slowing down charging times. One less thing to deal with in court.
