How do I power multiple Raspberry Pis?

4 Answers. The official Power Requirements of the Pi 4B is 5v, 3.0A – I.e. a total of 15W maximum power requirement from each of the Pis, so a 60W USB power supply, or larger, would be ideal.

Can 5 volts hurt you?

5 volts is completely safe. The resistance of your body (particularly across your heart which is what matters most as far as electricity safety is concerned) is about 100 kOhm. At 5 volts you’ll have about 50 microamps flowing across you, which is not even enough to feel.
