Will not speed up phone charging
Does not speed up the charging of my Samsung A70 phone in the car, which is the reason I was purchasing it for. When I plug the main plug in, it charges at full speed (1A), but when the secondary plug is inserted in another port it will slow down the charging almost to a halt (0.03A). I was expecting getting a boost in charging speed, but it seems the charge controller does not like bridging two separate USB ports.
Not sure how it would behave with a hard drive, I haven't tested it.
