Geekworm X1201 Ultra-Thin 5V UPS Shield for Raspberry Pi 5 |Max 5.1V 5A Output| Auto Power On|Safe Shutdown|Power Loss Detection

This little board opens up new vistas for portable Raspberry Pi 5 devices. I used mine to create a high performance VPN travel router by adding an M.2 E Key HAT to the Pi and a couple of external antennas. I used the Geekworm X1201 metal enclosure for this form factor. However, I did have to make a couple of extra holes in the case for the antennas. Being battery-powered, the device can be used to give you and your companions secure wifi in coffee shops, or while travelling, or in outdoor locations or anywhere a power source isn't easily available. With two 3300mAh rechargeable batteries, the board delivers around 4 hours of use in this particular use case. Although it powers the Pi and its M.2 HAT successfully, it's a little limited in terms of its ability to power external devices though.

So far so good, but the instructions could use clarification. Below are the issues I ran into and how I fixed them. Knocking off a star for that. (Hopfully they will update the instructions soon)I used sudo apt-get install for a couple additional dependencies during step 2.1."sudo apt-get install i2c-tools""sudo apt-get install python3-smbus"The reason for I2c-tools is I wasn't able to use i2cdetect in section 2.9. I needed to have i2ctools to do so.The reason for python3-smbus is I got an error in 3.1 saying no module named smbus. By installing python3-smbus the script ran correctly.In section 3.1 I used the command:"cd x120x" prior to running python3.bat.py.The reason is the scripts I downloaded earlier in section 2.7 are in the the folder "x120x" rather than the default folder I was in after rebooting in step 2.8.Otherwise everything seems to be working great.

i ordered this for my son, and this is his review:"The battery shield does as it is suppose to and keeps the pi5 powered on, (and with the condition that you did the instructions in the software section of the product and made the changes needed.) however, i did noticed that once it triggers an under-voltage spike, it doesnt go away, and i have had remove the power icon from the system tray so it does constantly show that there was a under-voltage spike and not that the current system IS under-voltage."

on rpi 5 gives low voltage warning, even when a 5 am power supply is used. Unsure if there is an update to resolve this. Also automated software does not function properly
