If this 35w is 35w for each port, then it's going to charge a 13 Pro Max faster than the Apple 20w. The 13 Pro Max can charge up to 27w. The iPhone 13 Pro up to 23w. The iPhone 13 up to 22w. I think the 12 Pro Max up to 23w. Older iPhones 18 to 20w. So, unless you have a 12 or 13 series iPhone, it's not going to charge any faster than the 20w charger. But you can charge 2 devices at the same time on one charger. The $59 is in line with the better 3rd party chargers, like Anker. Anker's 65w 2 port charger (20 and 45) is $54.99.
