I've seen a number of posts about people having issues with booting, and one thing brought up a lot is not using a good power supply. I ordered one of the Pine power supplies as an add on, but don't have it yet. In the meantime, I've ordered from one Amazon that was marked as being for Raspberry Pi 3, rated at 5V, 2.5A, by CanaKit.
What I want to know though, is how high of a current rating can be used? I don't know if higher current rated power supplies are out there, but if so, could I use a 5.0A, or even a 10.0A? What is the limit? I've read that plugging in externals like USB stuff could draw more current and cause voltage drops, so I'm wondering if I should be trying to find a higher current power supply if I plan on plugging in stuff.
And if a supply is rated for higher current, does that mean the current is available if necessary, or will it be always cranking out that much? If the board is only trying to draw 2.1A, will a 5.0A supply only supply the 2.1A? I don't want to get a supply that risks burning out the board.
Sorry if these are obvious, I'm not great with electrical stuff. Thanks!
