So I decide to crack open my MK1, labeled as 1.5, electronics and see what this 90 usd device was. I was having issues running a few devices on the hub and my tablet was slowly discharge while I was using it. Here are the pics.

Full system

USB-C PD chip

USB Hub

Essentially a 15W 5V (2.5A) power supply to a dedicated usb charger and a USB Hub. Hub is essentially a 5 port 2.0 Hub. There is a three position switch that I can't seem to figure out it's purpose, nothing power delivery wise changes in any position.
I tested it with a number of power inputs to the hub and regardless the max output power is 0.5A and it only drops as you add more devices to the hub. This is why my Samsung Tab A couldn't remain charged while being used. It's peak power draw is ~8W, idle, varies 3.3 / 5.9 / 6.7 Watt, and standby 0.15 / 0.6 Watt is the best info I could get. So that's barely going to be enough to charge while in standby. That tablet needs a dedicated 2A power delivery source to charge while in use. Now with my other devices plugged into that hub this system couldn't even meet the minimum needed to power my Audio Quest Dragonfly DAC.
