Value for this product was too good to be true... after using a 2018 15" MacBook Pro with this, it seems to have overheated and melted. Didn't damage anything else fortunately, and surprisingly didn't blow a fuse, but it was really inconvenient to be quite literally out in the woods on a filming trip with no other way to power my laptop. I'd certainly pay double for a reliable product. I wasn't even using both ports simultaneously, only the USB-C port.
