| Sep 20, 2022 at 7:24 | comment | added | Dmitry Grigoryev | Start by measuring the voltage you deliver to the Pi, using separate pins (e.g. 4 and 14). It should be above 5V ideally. | |

| Sep 20, 2022 at 7:10 | comment | added | Dmitry Grigoryev | Yes, and that's exactly why it's a useful information. A broken Pi often takes very little current, and excessive current can indicate problems as well. The nominal current depends on the model though, so you should say which one you have. | |

| Sep 20, 2022 at 7:06 | comment | added | Andreas | But as far as I understand it, the Pi takes that Current that he needs. | |
| Sep 20, 2022 at 7:04 | comment | added | Dmitry Grigoryev | Now, 800 mA can be too much or too little, depending on you Pi model. It sounds like a reasonable current for a Pi 4 with no CPU load. Is that so? | |
| Sep 20, 2022 at 7:03 | comment | added | Dmitry Grigoryev | I added this info to the question. I know it's obvious to you, but it's absolutely not for other people, and just asks for irrelevant answers such as "check your cables" etc. | |
