Raspberry Pi 4 Power Consumption Mah

The official power supply.

Raspberry pi 4 power consumption mah. Generally trying to power a raspberry pi with a single 18650 cell is not a good idea. The official raspberry pi 4 power supply which costs around 10 12 does the trick but so will any phone or laptop charger that meets these minimum standards and outputs to usb c. The power requirements of the raspberry pi increase as you make use of the various interfaces on the raspberry pi. For raspberry pi 0 3 we recommend our 2 5a micro usb supply.

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. I m seeing power consumption a little higher than your measurements but this may depend on if you re booting to a cli or desktop and what networking you are using. Of course this will strongly depend on how it is used and what devices are connected but i am trying to get a rough estimate for my use case to be able to decide what battery to get while trying to keep the budget low i don t want to go straight for the 12000 mah option unless necessary. The biggest issue i see with this increased power consumption is the additional heat.

Plug in the numbers to the calculator below and get a very rough estimate of how long you ll get out of each charge. For raspberry pi 4 we recommend our 3a usb c supply.

Why don t you try using a sleepy pi 2 to optimise your battery life and get the longest runtime you can.

Here are 10 ways to power a raspberry pi which you may consider when troubleshooting or experimenting with different projects. You can also. For how long can the raspberry pi run when powered from a battery of a given capacity. This applies to the raspberry pi 3 models as well as the raspberry pi 4 at least i haven t obtained a raspberry pi zero yet to see how much i can reduce its power consumption.

The recommended amount is between 700ma for a raspberry pi model a and up to 2 5a for a raspberry pi 3 model b see power supply requirements in the magpi issue 56 page 39. The raspberry pi boards typically draw much lower amounts between 200 and 500ma. How long will it power you raspberry pi for. While not the most interesting or mobile option in this list the official raspberry pi power supply unit psu offers 5 1v at 2 5a plenty for most pi projects.

An individual gpio pin can only safely draw 16ma. I will be adding power consumption statistics to this page as time goes on.
