We recommend powering the ODROID-N2/C4 with a good quality 12V/2A power adapter.
However, using a good quality 15V/4A power adapter is also OK if you already have one handy.
There is a bad luck case has reported by our forum, 5V Step-Down Converter(U25) on C4 has damaged when 15V/4A power supply plugged into C4 (☞ https://forum.odroid.com/viewtopic.php?f=205&t=42112).
So we do Not recommend using the 15V/4A Power supply with C4.
Note that 15V/4V is not necessary for the N2, N2+ and C4, 12V/2A is plenty enough.
On the other hand 15V/4A is required for the HC4 and the H2 series because these boards may power mechanical hard drives.
