[Discuss] Raspberry Pi low voltage indication

[Mark G.]

Hi Murray,

Is the individual port on the power bar able to push more than 2A?
Sometimes those ports are themselves limited to 1A each (for charging
only).

Also, the quality of the cable could be a factor.  Does using a 
different cable make a difference?

Can you send the make/model of the "3A powered USB 3.9 bar"?
