bought this for wall charging that supports usb-c as the usb-c devices these days skipped them and for them to double up as int plug, and I am lazy to power charge from the laptops or imacs. I am not sure why the design sucks more heat to the plug instead of going into charging. I used same cable, but the phone brand's charger is charge the 80% battery phone in 25mins, this plug needs 30mins, and the plug is hot at 5 mins of charging. The phone brand charge is about 29deg, while this is 33deg. Maybe the engineers can design better next time. Also this device just only has 1 usb, 1 usb c. I thought there was a 1 3 plug during time of buying but there isnt, usually when we buy these as additional charging, more variety will help.
