Review on 💻 JXMOX USB C to USB Adapter [2-Pack] - Compatible with MacBook Pro, Chromebook, Pixelbook, Microsoft Surface Go, Galaxy S8 S9 S10 S20 Plus, Note 8 9, Pixel 2 3 - Thunderbolt 3 to USB 3.0 OTG Adapter (Blue) by Jodi Besch

There was a similar product until I accidentally stepped on it. I had this so I could plug the cable into the charger's fast charge port C. When mine broke, I was in dire need of a replacement. I bought this pack of two and two days later it arrived as scheduled. Now it is connected to my phone. In about three minutes it went from 0 (zero) to about 16%. That is fast! So I think the item works fine. [Charging took about 10 or 12 minutes. It's now 50% charged] So my guess is that a cell phone charged with a "fast" charger will go from zero to full in about half an hour. Great, no more waiting for hours.
