I was in a quandary over how to charge two phones from the front charging pads AND use my USB flash drive for music. As most know, the wired charging pad in the console is the only place where data is transferred to the Model 3. Also, I have ordered a Nomad wireless charging pad, and it is suggested that both USB ports be used in order to obtain full charging. I ordered a compact USB hub from Amazon, and used my USB tester to determine if there was any loss in amperage due to the hub. I am attaching photos of my tests. My cheap little tester shows 1.14 amps from the hub at 4.96 volts. (The little white thing on top of the hub is my USB flash drive.) For comparison, I also photographed the right side without the hub, showing also 1.14 amps at 5 volts. I moved to the house and took a photo with a standard USB and also got 1.14 amps at 5.24 volts. I was starting to get worried that my USB meter was stuck at 1.14 amps. So I tried a known slow charge USB port on my computer. This showed 0.38 amps at 4.97 volts. So it looks like I will be using the USB hub to use my data off the flash drive, while also charging my phone. FYI, the music does play just as exceptional with or without the hub.
