There are of course other factors that come into play such as the operating system used.
Raspberry pi power consumption.
Let s assume this is 3 watts just for this example.
Emeter clamp meter and bench psu all being used to check power consumption of raspberry pi 3b plus.
Shooting video is done without saving the video output to the sd card.
The raspberry pi boards typically draw much lower amounts between 200 and 500ma.
Pi power consumption results.
Please also have a look at the video.
The gpio pins can draw 50ma safely distributed across all the pins.
The raspberry pi zero uses about the same amount of power as the a and at least 50 less power than any other pi b 2 b 3 b.
The newer pi 3 a is slightly lower than the b but only if the on board wi fi is disabled.
The power requirements of the raspberry pi increase as you make use of the various interfaces on the raspberry pi.
An individual gpio pin can only safely draw 16ma.
In this tutorial you will learn super easy way to monitor power consumption of raspberry pi and its official 7 touchscreen display using usb voltage and current detection module.
Here are the results.
For raspberry pi 4 we recommend our 3a usb c supply.
In this case the operating system is rasbpian lite.
All figures in milliamps ma.
How much power does raspberry pi 4b use power consumption pi4b.
Measuring raspberry pi power consumption.
Do yoi think that when i connect a 2 5 hard drive to a raspberry pi will the 5v 3a power supply be able to power the rpi 4 and the 2 5 drive.

I will be adding power consumption statistics to this page as time goes on.
Here are the same results presented as a chart.
For raspberry pi 0 3 we recommend our 2 5a micro usb supply.
If the raspberry pi s power consumption averages 3 watts then you could use a battery that is 50wh the capacity of an average laptop battery is 43 to 85 wh to power.
The same approach can be used f.
The pi zero w has the lowest power consumption whereas the pi 3 b 2018 has the highest.
I use the powerjive usb power meter for older pis with micro usb power inputs or the satechi usb c power meter for the pi 4 and newer to measure power consumption with the dramble and individual raspberry pis in all cases with nothing plugged into usb unless otherwise noted.
The power consumption per raspberry pi will depend on the model that you have at hand.
Current and voltage are measured using my emeter also used my clamp meter to confirm this time and calibrated shunt whilst performing four different activities.
The raspberry pi s average power consumption which will dictate how many hours per charge your battery life will be.
