I suggest connecting a 5-ohm or even a 1-ohm load across the output (no R-Pi) and then measuring the voltage. Run it until the regulator gets uncomfortably warm and if that happens very quickly maybe

Hi, I agree. I have an official RPI supply and got the low voltage warning (on RPI2,3 and 4). Checked the voltage and it shows 5.14V. Current consumption was about 1A. I bought one of these of the auc

#hardware #raspberrypi

Also don't forget that anything that is pulling power from one of the USB ports can cause low voltage issues even with the proper supply. Total power all 4 USB ports combines can provide is 1.2A Get B

What is this thing with available "official" power supplies being capable of no more than the Pi requires? Why not make one capable of say 6 amps (or even more) and a short/heavier cord to reduce volt

Agree with the above comments. The power supply for the Pi4 is fairly critical. I've seen issues with my LCD display when running off a battery, which then promptly went away with using the "approved"

John, maybe this will help: The "official" power supply for the 4B is 5.1v., 4 A. A power supply for the 3B+ I have found by trial and error is a 5.25 V., 3 A. This will keep you from getting "low pow

Big enough power supply? I notice the web site explicitly labels the power input at "5v 3A" A description of "doesn't work" would be helpful. Doesn't light up? Display unreadable? "No signal" error? 7

Not clear what difficulties you're having. Though my experience may help. Had bought an 11" monitor rated for both 12 VDC and included AC adapter for use with my RPi. Could not get the monitor to work

I am inclined to believe the SD card itself may be susceptible--I am pretty sure mine was somehow physically damaged as I was unable to re-flash and re-use it. Likely this was related to my own lack o
