Raspberry Pi 3 Power Consumption Watts

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. Emeter clamp meter and bench psu all being used to check power consumption of raspberry pi 3b plus. 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 raspberry pi for 16 hours at that average power consumption.

Raspberry pi 3 power consumption watts.

Here are the same results presented as a chart. This matters only when selecting a psu to run your pi you already have the official recommendations of a 3 0 amp psu for that. Pi state power consumption. Pi power consumption results.

See this post for more information and instructions how to do all of the above. Shooting video is done without saving the video output to the sd card. Usage depends on what you re doing with the pi. The pi zero w has the lowest power consumption whereas the pi 3 b 2018 has the highest.

The uni t clamp meter reads to 3 decimal places of an amp but it won t give a true picture of peak instantaneous current e g. Let s assume this is 3 watts just for this example. Here are the results. Conserve raspberry pis power consumption.

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. For raspberry pi 4 we recommend our 3a usb c supply. The raspberry pi boards typically draw much lower amounts between 200 and 500ma. 540 ma 2 7 w ab n 100 c 10 uncached 1010 ma 5 1 w 400 cpu load stress cpu 4 1280 ma 6 4 w raspberry pi 3 b.

The recommended psu is 5 1v 2 5a which is 0 5a higher than for previous pis. An individual gpio pin can only safely draw 16ma. The power requirements of the raspberry pi increase as you make use of the various interfaces on the raspberry pi. All figures in milliamps ma.

It also requires a bit more electrical power if you re going to be hammering those four a53 cpu cores. On power up of the arm cores from idle. Raspberry pi 4 b. The raspberry pi 3 launched this week is more powerful than the pi2.

For raspberry pi 0 3 we recommend our 2 5a micro usb supply. The gpio pins can draw 50ma safely distributed across all the pins. The newer pi 3 a is slightly lower than the b but only if the on board wi fi is disabled.
