JY-UO135N4GS head unit USB power output
#1
It seems the power output on the USB ports is quite low.  My Samsung galaxy S8 says charging(2+ hours till fully charged).  However, it sometimes barely maintains current battery percentage and usually slowly discharges over time.  Is there a way to boost the power output from the USB ports?

My unit is: JY-UO135N4GS
