Loading speed is useless to you. I connected my Samsung Galaxy S10 and it said it would take 13 hours to charge. I left it overnight. The next morning it was still less than 1 percent, so the estimate wasn't a mistake. The cable was plugged into a Samsung fast charging socket. The same plug with a standard cord charges my phone from 0 to 100% in an hour and 40 minutes. So these cables are about 6 times slower than a standard cable. One more note: the little magnetic connector sticking out from the bottom of my phone is annoying. Personally, I hold my devices with my pinky on the bottom edge. A small metal pin protrudes from the liner, making it uncomfortable to hold. If the loading speed was acceptable I would ignore this part. I was very happy with them but they are not worth it. The hinge mechanism also seems weak. I wouldn't expect them to last very long.
