Stand is ok, obviously marketing of 20W is misleading as even at claimes 9V and 1.67A it can consume a maximum of 15.03W and at claimed efficiency of 73% can provide 11W of charge (theoretically). It didn't work with included cheap USB cable threw that way and using other USB (Micro) cable with which I can charge my iPhone SE 2020.
I have an iPhone and a Samsung. The charger works poorly on both. I have to turn the phones 90 degrees and then find a very narrow sweet spot for this to charge my phones. Disappointed.
