Banana Pi power supplies: 5 V over USB for the M boards, 12 V or 19 V barrel jacks for the router boards
Banana Pi boards don't share one power standard. The BPI-M5 and BPI-M4 Zero take 5 V / 3 A over USB, the BPI-R3 needs 12 V / 2 A, the BPI-R4 12 V / 5.2 A or 19 V / 3.2 A, and the BPI-R3 Mini 12 V (20 W) or USB-C PD. Check each board's page before reusing a supply.

5 V / 3 A over USB (the spec table reads "Micro USB (TYPE C)"; check the connector on your board)
BPI-M4 Zero
5 V / 3 A, USB Type-C
BPI-R3
12 V / 2 A, DC jack
BPI-R3 Mini
12 V (20 W) or USB Type-C PD
BPI-R4
12 V / 5.2 A or 19 V / 3.2 A
BPI-F3
DC input and USB Type-C (no rating stated in the spec table)
BPI-M7
see the Raspberry Pi alternatives overview (USB-C PD)
Rules
Don't mix up router and SBC supplies. A 5 V USB-C phone charger can't power a BPI-R3 or R4, and a 12 V barrel supply must never go into a 5 V board.
BPI-R4 with a Wi-Fi card: OpenWrt's device page states the optional Wi-Fi 7 module needs the 19 V / 3.2 A option (see the BPI-R4 item).
Budget for peripherals. NVMe SSDs, 4G/5G modules and USB disks draw from the same supply. Undersized supplies show up as random reboots, disappearing SSDs or modems that reset.
5 V over USB-C: the M boards take 5 V. Chargers that advertise their wattage at higher USB PD voltages may deliver less current at 5 V, so check the 5 V rating on the label.
BPI-F3: the spec table names the inputs but no rating. Check the board's getting-started guide or ask the vendor before choosing a supply.
