Read the statement by Michael Teeuw here.
Can the usb port from a monitor power the rpi3?
-
That’s correct, and that’s because of their power outputs. You have to find out that powered and that has a nice high output. I actually run one of my rpis off of an Anker wall charger that outputs up to 2.4Amps per port.

@KirAsh4 ya a wall powered one will surely supply nice output power. If you want to share your Anker model - feel free :p

Lots and lots of them on Amazon. It really depends on your application. I have both 2, 4, and 5 ports around the house for various things. Hit Amazon, and search for ‘Anker wall charger’. Then look at their outputs and do the math. For example, if you see a 4-port, 40W, the calculation is:
40W / 4 ports = 10W per port
Each port supplies 5V, so 10W / 5V = 2Amps per port.Read the descriptions on them. I generally only buy those that can supply upwards of 2.4Amps on at least 1 port (and 2Amps on the others). But they have models that can supply that much on all ports as well.

@KirAsh4 I think it’s rather 40W / 4 ports = 10W per port :-) but no prob I got the math ;-) I will have a look and again and let you know in case. Thx so much for your time! Appreciated.

Yep, mistyped … corrected it now.

I’m using a NextGadget 20W desk charger. Plenty of power, but I just discovered that the cord is a bit short.
If you’re looking for 2.4 Amps per port, you might want to look at Skiva.

@bhepler thx you very much for sharing! :) I will have a look
