How much energy does the Raspberry Pi consume in a day?
2013年2月20日 · Pi4 B at idle = 2.85 W -> daily 68.4 Wh. Pi4 B at 100% * 4 CPUs = 6.4 W -> daily 154 Wh. The Zero, A+ and B+ really offer huge improvements in the power circuitry. Wow! Note that the Pi 2 Model B is a 4-core machine with each core idling near 0 and maxing near 0.25 W power demand.
pi 2 - Can I power a Pi through a 5V pin? - Raspberry Pi Stack …
2018年1月11日 · My Raspberry is a controller for an APA 102 LED strip. The strip itself uses a lot of current, so I can't power it from the 5V pin of the Raspberry (it would most likely destroy it). But I can easily use the 5V / 10A power supply for the LEDs to also power the Raspberry Pi through the 5V pin, hence using the pin as an input.

Raspberry Pi 3 vs Pi 2 power consumption and heat dissipation
2016年2月29日 · 2. 2.5 Amps is just a very high, safe figure -- it assumes the pi itself may use up to 1 Amp (which obviously it doesn't, if goobering's charts are correct) and the USB could use up to 1.2 Amps. However, considering what's on the market you might as well get a 2.5 Amp supply. 3 is obviously going to be overkill, but OTOH if you have a decent ...
