Willard GooseySuccess! Northpada Pi4 power brick, 3 amps at +5 and it has a switch and my Pi2 doesn't show the dreaded yellow lightning bolt at power-up!
The switch is important, this pi2 runs RISC OS and I love it but it's not that hard to crash the machine so bad it needs a power cycle. (esp since i insist on playing with old not-really arm7 clean binaries)
