I bought a Raspberry pi 5, sadly it didn't arrive with an adpater, so I used a mobile charger's adapter for its power and connected it with keyboard, mouse, and a monitor but when I try to boot the raspberry, it turns on for few seconds before shutting down imeditatly. I think it the issue with PS so I bought a charger with 5V and 6A would there be any issues if I use that? because in the website the mentioned that it needs 5v and 5A power. moreover because of my location, there are no official raspberry pi 5 adapters
