The Raspberry Pi is a compact, versatile computer that has become a favorite among hobbyists, educators, and developers. While it is typically powered via a USB connection to a power outlet, many projects require mobility or backup power. This is where power banks come into play, providing a portable and reliable energy source for Raspberry Pi devices.

Why Use a Power Bank with a Raspberry Pi?
Power banks offer several advantages for Raspberry Pi users. They enable portability for mobile projects such as robots, drones, and IoT devices. They serve as an uninterrupted power supply (UPS) during power outages or unstable electricity. They also support outdoor applications, powering projects in remote or outdoor locations where outlets are unavailable.
Key Factors to Consider When Choosing a Power Bank
When selecting a power bank for your Raspberry Pi, consider the following factors.
Capacity (mAh): Capacity determines how long a power bank can run your Raspberry Pi. For most Raspberry Pi models, a power bank with 10,000 mAh can power the device for 8–10 hours, depending on the load. Higher-capacity power banks (e.g., 20,000 mAh) are ideal for longer runtimes or powering additional peripherals.
Output Voltage and Current: The Raspberry Pi requires stable power to function properly. The standard voltage requirement is 5V, so ensure the power bank delivers this reliably. The recommended current depends on the model. For a Raspberry Pi Zero, 0.5–1A is sufficient, while Raspberry Pi 3 and 4 models require 2.5–3A. Choose a power bank with at least 3A output for compatibility with all models.
USB Ports: If your project involves additional devices such as displays, sensors, or USB peripherals, look for a power bank with multiple USB ports to power them simultaneously.
Efficiency and Quality: Not all power banks are created equal. Opt for reputable brands that offer efficiency and consistent output to avoid damaging your Raspberry Pi.
Size and Portability: Smaller power banks are ideal for compact projects, while larger ones are better for high-power setups requiring extended runtime.
How to Connect a Power Bank to a Raspberry Pi
Choose the right cable and use a high-quality USB cable to connect the power bank to the Raspberry Pi’s power port. Check the voltage and current ratings to ensure the power bank’s output matches the Raspberry Pi’s requirements. Monitor battery levels to avoid interruptions during critical operations.
