I am in need of putting my pi approx 3 metres away from a power socket, basically on top of some tall bookcase shelves.
I am currently using a raspberry pi 2, and I bought a micro usb extension cable from ebay china, the cable seems to work well, but did have a bit of an initial red flashing power light, but it's now stable.
I did a bit of googling and found these power requirements for the raspberry pi's I potentially would be using.
Raspberry Pi 2 Model B 1.8A
Raspberry Pi 3 Model B 2.5A
I thought that I could get a standard usb plug charger and use a high quality 24awg or 22awg usb to micro usb cable, this would be fine for the raspberry pi 2, but not for the raspberry pi 3 as all the usb plug chargers I have seen have a max 2.4A output per port which is insufficient for the raspberry pi 3.
Does anyone have any advice on what I could do in this instance if I was to move from a pi 2 to a pi 3?
It's a shame the raspberry foundation themselves weren't able to offer a higher quality usb charger with a longer cable.
Just stumbled upon this cable: https://www.adafruit.com/product/1995
, high quality cable, although shorter than I needed and wrong plug type as I'm in the UK. Am hoping to find something similar with a longer cable and the correct plug.
