Review on Power Up on-the-go with Monster 3-Port CLA 💪 Power Adapter: USB-C (Power Delivery), USB-A, CLA Socket Extension by Ryan Koser

I'll be brief, the USB-A connection is very slow, it can keep my iPhone X at the same battery percentage when the screen and Waze but don't charge it further . The USB-C connection should be very fast, 18W, which is almost as fast as an iPhone fast charger, but it doesn't work. The iPhone does not recognize it and does not change the phone. So yeah, I found it pretty useless.
