Review: Reliable UPS for my Pi 4 mobile lab - I put this UPS HAT on a Raspberry Pi 4B as part of a little “mobile lab” setup and it has been great so far. My stack is a Pi 4B on Raspberry Pi OS, a GeekPi PWM cooling hat with a small screen I am not really using yet, and a Panda PAU0F USB Wi-Fi adapter, all powered through this board with two 18650 batteries. Setup was easy. I watched the video the seller links, dropped the 18650 cells into the holder, plugged USB-C power into the hat, and let the hat feed the Pi through the GPIO header. It powered up on the first try and after that I mostly stopped thinking about it. The real test for me was what happens when you pull the plug. When I unplug the USB-C input, the Pi just keeps running. No reboot, no undervoltage icon, no SD card complaints. I have let this setup run on battery for a little over three hours and it stayed completely stable the whole time, which is more than enough for how I plan to use it. I actually started with a regular USB power bank and assumed that would work as a UPS. It did not. As soon as I unplugged the power bank from the wall, the Pi died instantly. That is what pushed me to try a proper UPS hat, and this one does exactly what I wanted. It turned my Pi 4 into something I can unplug, move around, or briefly lose mains on without worrying about corrupting the SD card.
Review: Easy To Use With Clear Documentation - Product works very well, and and provides much more power than other similar systems. I'm able to power a Raspberry Pi 4 as well as a 5V USB powered router from the 5V pins on top of the board. They likely don't link to it because desertcart blocks them, but they also have extremely good documentation on their wiki which is easily found by google searching "X728 Geekworm." Their documentation provides both hardware specifications, as well as links to code repos to see how you can read current voltage and battery life status in for either display, auto timeout features, etc.

## Questions & Answers

**Q: Is the recharge threshold and terminal battery voltage adjustable? I want to keep the batteries between 80% and 20%**
A: No. I don't think this is possible, unlesss you write a script that monitors the voltage or % of charge, and open a relay that would cut off the power input to the system... You would need some external equipment (arduino?) for that.

**Q: Are the batteries hot-swappable? In other words, can I connect an external power supply and swap the batteries out while that is on?**
A: Hi friend,
Sorry that the X728 on board 18650 batteries does not support hot-swappable, please swap the batteries after power cut off.
best regards,
Geekworm Team

**Q: Does the rtc have a separate battery? or does it run on the 18650 batteries? what happens if you remove them? will it "lose" time?**
A: Hi friend,
The RTC function runs on the 18650 batteries. It will "lose" time if you remove the 18650 batteries.
best regards,
Geekworm Team

**Q: Can I use more than two batteries with the x728?**
A: It holds two batteries,  it does have an second input for more battery boards.

### ⭐⭐⭐⭐⭐ Really useful UPS for my RPI
*by J***9 on May 1, 2021*

I bought this for my RPI to power it through blackouts, and it works really great. I tested it and it lasted over 24 hours with six 18650 batteries. Recently I was having problems with it rebooting randomly and the customer service was very responsive and helpful! As others have mentioned I do wish it was possible to dim the LEDs via software or switches, but I have a packet of Light Dims which work okay.
