I have some pi's, but still a beginner. I am currently building a standalone computer based on a Raspberry Pi 2B and a 10.1" monitor.
Anyway, i am currently using a wifi dongle ( TP-LINK wn721n ) which works OK but i suspect is drawing too much current.
Also, as the battery is more or less limited (2.2Ah 12v gel battery) , i was thinking of optimizing power.
So my question is, how much will Raspberry Pi 3 with its embedded wifi consume (in watts) compared to Raspberry Pi 2B with said TP-LINK wifi dongle?
Will the PI3 be better (i.e.: more efficient) than 2B under those conditions?
I would make the calculations but empirical knowledge is always welcomed.
Also, i tried looking for this but most comparissons are made with usb dongle, example:
All of the benchmarks below were carried out with just a USB keyboard and mouse connected with power supplied from the official Raspberry Pi Power Supply, with the exception of the WiFi dongle test in which the USB WiFi dongle was also connected. The Pis were naked, i.e. not in a Pibow, except for the onboard WiFi in Pibow test.
Thanks in advance!
I found this chart, looks ok although won't specify USB brand or type. Also HDMI off and in my case i'm using it:
