$19 is a really good price for a 45W USB-C Power Delivery wall charger, but this one is particularly notable for including a 6.6' USB-C to C cable in the box. That would normally set you back at least $5 or so on its own.
45W is more than enough to charge a Nintendo Switch or 12" MacBook at full speed, and it should be able to recharge a 13" MacBook Pro as well, albeit somewhat slower than its included 61W charger.
