The lithium battery mobile power supply for Raspbery PI allows the Raspbery PI motherboard to work up to 9 hours.
Of course, I am not limited to the Raspbery Pi, I have 2 USB-A interfaces onboard, and 1 can power the Pi motherboard. The other can power devices such as embedded LCD screens if needed.
I have integrated an imported lithium battery charging/boost management chip. Bring your own battery and weigh only 80g. R & D in strict accordance with the International Raspberry Pi HAT expansion version, with a simple copper column and Raspberry Pi motherboard cascading installation.
