The link didn't work for me so I searched on Amazon and found this one: https://www.amazon.com/Anker-4-Port-Macbook-Surface-Notebook/dp/B00XMD7KPU. However, it says that it's not for charging. Is this the one you're using or a different one?
I got this one: SIIG USB 2.0 Portable 2-Port Hub (JU-H20011-S1) https://www.amazon.com/dp/B005ORPJ14/ref=cm_sw_r_cp_api_qiIWBbJVRQ918
I’m able to charge my wife’s iPhone and record from TeslaCam with a flash drive plugged in at the same time.
