Updated 20 days ago · Based on the Amazon listing and published specifications, not hands-on testing.
A neat way to keep a Pi Zero project running through power cuts or away from an outlet. The power button and auto start share a bus pin, so they cannot run alongside sensor bus devices.

Overview
PiSugar makes this battery module to clip under a Raspberry Pi Zero and power it like a small uninterruptible supply. When outside power drops it carries on supplying the board, and reconnecting power can trigger a boot for unattended builds.
Portable and unattended Pi Zero builds gain backup power without taking over the GPIO header, since the board attaches from below. The limit is a shared pin: auto start and the custom button cannot be used while the board talks to sensor bus devices.
Who it's for
Pi Zero projects such as remote sensors, portable gadgets and headless servers that must ride out power interruptions. Builders using full size Raspberry Pi boards need a different module.
Pros and cons
- Pi Zero stays powered during outages
- Boot on power return for unattended setups
- GPIO button doubles as a custom input
- Input pad allows solar or wireless charging
- Auto start and button conflict with I2C
- Only for Pi Zero series boards
- Battery status display details not listed
Performance notes
Runtime depends on how much current the Pi and attached hardware draw, so extra peripherals shorten it. The UPS behaviour reports external power status to the system, letting software react to an outage. Charging alternatives depend on what you wire to the input pad.

Frequently asked questions
How do I charge the PiSugar S other than by USB?
The input pad lets you add other charging methods, such as solar charging or wireless charging. The standard input is 5V2A.
Does the PiSugar S work with I2C devices?
Partly. It uses the I2C SCL GPIO to start the Raspberry Pi, so the automatic startup function and the custom button cannot be used together with I2C communication.
How long does the PiSugar S run a Pi Zero W?
The listing says the 1200mAh pack can work more than 6 hours with a Zero W.
Does the PiSugar S block the GPIO pins?
No. It connects from the bottom without affecting GPIO expansion, and 4 screws are included.
Can the PiSugar S turn the Pi on automatically?
Yes. External power access can trigger boot, and the GPIO button can turn the device on when it is off.
