PiJuice HAT for Battery-Powered Pi Zero
The Raspberry Pi Zero is a frugal little computer. But without a power socket, you might be surprised how quickly it can drain a battery. Active power management is the order of the day.

Power Saver
The Raspberry Pi Pico’s high-performance chip is trimmed for I/O and does not try to save power. However, a few tricks in battery mode can keep it running longer.
Plugged In
Ecosystems with pluggable Raspberry Pi modules, sensors, and displays are a great choice if you don’t want to – or can’t – solder but still want to extend your hardware.
Self-Sufficient
Powering your Pi Pico with solar may not solve the current energy crisis, but it will save you from changing or recharging batteries.
