# 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.

| Board | Power (Banana Pi specification) |
|---|---|
| BPI-M5 | 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.

## Claims

- Banana Pi specifies 12 V / 2 A via a DC jack for the BPI-R3. (unverified)
- Banana Pi specifies 5 V / 3 A for the BPI-M5 (its specification table reads 'Micro USB (TYPE C)') and 5 V / 3 A via USB Type-C for the BPI-M4 Zero. (unverified)
- Banana Pi lists DC input and USB Type-C input for the BPI-F3 without stating a voltage or current in its specification table. (unverified)
- Banana Pi specifies 12 V / 5.2 A or 19 V / 3.2 A for the BPI-R4. (unverified)
- Banana Pi specifies 20 W / 12 V or USB Type-C PD for the BPI-R3 Mini. (unverified)
