Can I supply power with 5V 2Amp to Raspberry pi 4? Currently 5V 3Amp chargers by Raspberry Pi are out of stock , so I am using phone charger with 5V 2Amp along with Type C adapter.
The Pi4B reportedly needs about 1.5 amps under load (see this Magpi chart). Thanks to Ghanima for that link
You only need more if you have power hungry peripherals which need powering through the Pi.
