If you're building a Raspberry Pi Zero UPS, you can alternatively use the JuiceBox Zero, which is a little cheaper but can't be used for full-sized Pis. The hardwareįor power management, I'll be using the PiJuice, which was originally funded on Kickstarter. This is my recommended approach and the one I'll cover in this guide. The Pi can also monitor the battery to know when it's using battery power and whether to perform a safe shutdown when power is low. When power is lost, the power management board will keep things running for hours without issue. The board is effectively a complete portable power solution. Then, an AC adapter is connected to the power management board. This method involves connecting a power management circuit and battery directly to the Pi. Method #2: Power management board (recommended) Additionally, the Pi can't detect that it's on battery power (let alone how much power remains) so a safe shutdown is not possible. Unfortunately, portable power banks that meet these requirements are hard to find and expensive.

These numbers assume you don't have any peripherals plugged into the Pi or power bank that draw power. The power bank should output at least 2A for the Raspberry Pi 3, 2.5A for the Raspberry Pi 3 B+, or 1A for the Raspberry Pi Zero. Most power banks do not have this feature as it requires additional circuitry and is an edge case for most users. The power bank needs to be able to simultaneously charge and discharge in other words, while the power bank is charging, it's also outputting maximum power to one of its USB ports. There are a few factors to consider with this approach: Simultaneous charge/discharge The battery pack gets plugged into the wall and the Pi gets plugged into the battery pack. With this method, you essentially plug your Pi into a high-output power bank: basically, a juiced-up version of what you use to charge your phone while camping.

There are a few options for building your own Pi UPS.
