Product description: UPS uninterruptible power supply - power overlay for Raspberry Pi - 5V - Waveshare 18306
A UPS emergency power supply in the form of a power overlay for Raspberry Pi, which brings extra power to the module in case of power failure or while travelling. It is powered by two 18650 Li-Ion batteries and has an additional ON/OFF power button and USB type A port. The kit includes a power adapter.
A power cap that has space for two Li-Ion cells.Product compatible with Raspberry Pi
The manufacturer provides a Product Wiki Page that includes a user guide and technical documentation for each component.
The item for sale is the power overlay. Raspberry Pi and 18650 Li-Ion batteries must be purchased separately.

Uninterruptible Power Supply (UPS) - 5V power supply for Raspberry Pi - Waveshare 18306
The power overlay for Raspberry Pi 5 V from Waveshare features a built-in UPS. This allows the extension to be used both to provide power for transport, for example, and to protect the main board from the effects of sudden power outages.
Moreover, on the board there is a practical ON/OFF button for switching the power on and off, as well as a number of protection systems protecting against, among others, overvoltage, short circuit or reverse battery connection.
Raspberry Pi Hat Multifunctional Power Overlay
Using the Raspberry Pi Power Overlay with UPS from Waveshare allows you to ensure constant access to electricity and protection against sudden loss of power source. The extension also allows you to closely monitor power parameters in real time.
Additional information about this Raspberry Pi Hat power overlay can be found on the manufacturer's website and on the product Wiki page, which are linked in the "Useful Links" section below the description. A schematic of the board is also available there.
