Backup Power Options for Raspberry Pi
There are two primary solutions for providing backup power to a Raspberry Pi:
- Conventional 230/110V UPS
- Dedicated UPS for Raspberry Pi SBC
Conventional 230/110V UPS
Advantages:
- Widely available globally in various models and capacities.
- Can power multiple devices, such as routers, switches, or multiple Raspberry Pis.
Disadvantages:
- Larger in size and often equipped with fans, which may produce noise.
Recommended Model:
- Legrand UPS KEOR PDU (EAN: 3414971529380)
- Silent operation and tested for reliability.

Dedicated Raspberry Pi UPS
Advantages:
- Compact and silent.
- Designed specifically for Raspberry Pi, often as a HAT or a small external device.
- Equipped with popular 18650 cells for longer battery life, depending on the number of cells.
- Can interface with Raspberry Pi to detect low battery levels and initiate safe shutdowns.
Disadvantages:
- Less commonly available but can be ordered online.
- Suitable for a single Raspberry Pi only. You'd still need further backup power for the network.
