I gave this Adaptive Fast Charging Wall Charger a 3 of 5 because it works with my S9+, but it is slower than others by 2x. The good news is it works with your Samsung, and charges, OK, fast enough. Check independent analysis of Samsung and other USB & Cable configurations, and you find out the Adaptive Charging is not as fast as others. However, I would like to see Samsung produce or endorse 1) a Wall Outlet, skipping the plug, USB-A to USB-C 3.1 Gen 2 Ultra Fast Charging, and 2) a USB-A to USB-C 3.1, Gen 2 (Power & Data Transfer) Cable for truly fast charging and 10 Gbps Data Transfer Speeds, with the requisite protection for Over-Charge and Over-Heat, 3) And, make the cable 2 or 3 meters, and make the cable with an LED on the end so you can find it at in the dark, and it dims when plugged in so you know it is connected. That LED would require insignificant power consumption. Now, I suspect there is a problem with USB-A to USB-C, 3.1 Gen 2, cables at lengths of 2 to 3 meters (6+ to 9+ feet), so I would settle for 3.1 Gen 1 or 3.0 if that is all you can do with the LED at the end and some length beyond 1 meter. Users could keep the 1 meter (3+ foot) 3.1, Gen 2 cable or (. 5 meter cable) with your PC for when you need fast transfer and charging speeds. The longer cable is for charge over night or when you can wait. Then, at home USB right into the wall outlet with out all the plug adabtors. That would be the best, Please Samsung! Anyone have a better idea?
