“The laws of electronics and the open nature of the Raspberry Pi ecosystem means that you can of course use any device that provides 12 odd Watt at 5 volts.
Using the official supply removes any compatibility worries and supports the Raspberry Pi foundation. No more dreaded lightning bolts on startup or desktop popups about poor power.
Given the proliferation of merely good enough third party supplies, it is difficult to source the official ones. The Pi Hut is about the only reliable and accessible retailer left and therefore also worthy of your support.”
