Hello! I've attached my Raspberry Pi to the x1206 UPS hat and ensured proper contact for all pins. Inserted four 21700 batteries properly oriented (+to+, -to-). Connected monitor/mouse/keyboard.

Tried to power UPS via DC power jack using Geekworm recommended power supply.

Also tried to power UPS via USB-C power input (the one on UPS board, not the one on Raspberry PI board) using official Raspberry Pi 5 power supply.

In both cases - Raspberry Pi booted successfully. But it showed a notification: "This power supply is not capable of supplying 5A. Power to peripherals will be restricted."

Brief research showed that it might be due to Raspberry Pi expecting to being powered via it's Type-C port and not being able to perform handshake with power supply cable.

Keyboard I use is Keychron K6 Pro, which is capable of connecting via BlueTooth (which works fine with my Raspberry Pi), and via USB Type-A port (which resulted in red notification "USB Overcurrent. Please check your connected USB devices").

I doublechecked - bare RPi with no UPS hat powered via it's Type-C port with official RPi power supply doesn't show red notification if Keychron K6 Pro keyboard is connected to any of RPi's USB Type-A ports.

Does it create any risk for my keyboard? Does it create any risk for my USB Memory Sticks and the integrity of data transferred to external device?

Is your UPS truly provides enough power to RPi to power all of it's Type-A ports properly? If yes - how can I configure my RPi to have all USB Type-A ports fully powered? Can I disable handshake check? Is there anything else I can do to fix underpowered USB ports?
