The X728 reserves the 40-pin header that can be stacked with other Raspberry Pi accessory boards for enhanced applications. The X728 can also be used with the X825/X828/X829 (2.5" HDD/SSD Shield) and X857/X862/X872 (MSATA/M.2 SSD shield) for safe data backup. Review: I use these in an rpi5 cluster that is rackmounted. I choose this ups for my rpi5 because most of the dedicated rpi5 ones are bottom ones that don't work with the rack front io cutout due to increasing height below the rpi. These work well, but i wish the usb c power port was rear or forward facing as with my rpi cluster using the side is difficult cable managment wise. I've actually broke a usb c port off before taking the cluster out for maintainance. I particularly like the power switch header for safe shutdown with a momentary switch. It also has a power button on the board thats easier to access than the one on back of the pi. Review: 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. ## Features - [Function]X728 provides 5.1V 6000mA Power Backup for even the most demanding Raspberry Pi set ups, intelligent and safe power management, safe shutdown, auto power-on, full poweroff from software, and a real- time clock. - [User Manual] Refer to Geekworm WiKi search X728; Match metal case for X728, refer to X728-C1(ASIN:B09Z6C64NN).PSU for X728, refer to ASIN: B09J856PND. - [How to Power & Specifications]Power supply via Type-C socket : 5Vdc ±5%, ≥3A, Via DC power jack : 5Vdc ±5%, ≥4A; UPS output : 5.1V ±5% Max 6A; UPS charging current: 2.3~3.2A; Terminal Battery Voltage : 4.24V; Recharge Threshold : 4.1V - [Important Note]√1.

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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by J***R on 6 April 2026* I use these in an rpi5 cluster that is rackmounted.

Turning off power without proper shutdown runs the risk of corrupting the SD card. I needed reliable power management for several Raspberry Pi's running OctoPrint, a media control server and security server. I could not find a working system. In frustration, I had resigned myself to building my own system using an Arduino. That involved writing a bunch of C++ code, as well as designing and ordering my own printed circuit boards. Doable, but not a lot of fun. That's where the X728 system comes in. It does power management well but also includes a battery backup using 18650 lithium batteries. It's a hat, so it plugs in on top of the Raspberry Pi. Standoffs and screws are included so you can securely mount the hat on your Raspberry Pi. It has connectors for a lighted power switch and additional lithium batteries. Instructions are available on the GeekWorm web site. There is a script that needs to be downloaded and then run. It installs several scripts on the Raspberry Pi. You run a few commands to register startup and shutdown scripts. About 15 minutes work and it's done. Easy peasy. My first X728 V2.1 had a problem. It would not shut down. I purchased several X728 V2.1 boards, so it was easy to swap boards. Yep, the first board was defective. GeekWorm tech support was awesome so I'm only knocking one star off. This is the best Raspberry Pi power management solution I have found. Being able to safely control power is essential. The addition of battery backup for critical servers is HUGE! I wish GeekWorm had better quality control, but support is quite responsive. Support is based in China so there is a 24-hour delay to get a response. They start with very basic questions, so it takes a few iterations to find a solution. Update: I have purchased several more X-728 boards and almost each one has problems. Connectors not soldered on, boards that do not work, the list goes on. I want to love this board. I really do. But if you purchase one, resign yourself to dealing with Geekworm's quality control issues. Too bad, because there is a lot to like about this board. ## Frequently Bought Together - Geekworm for Raspberry Pi UPS, X728 (Max 5.1V 6A) UPS & Power Management Board with AC Power Loss Detection|Auto Power On|Safe Shutdown|Battery Capacity Reading|Low Battery Auto Shutdown|Buzzer - Geekworm Cooling Fan Expansion Board (X728-A1) for X728 & Raspberry Pi 4 Model B/ 3B+/ 3B/ 2B - Geekworm 11mm Thickness Embedded Heatsink (P165-B) for Raspberry Pi 4, Armor Aluminum Radiator Compatible with Raspberry Pi 4 Model B Computer and Pi 4 Expansion Board Support POE Extension --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.kg/products/487149966-geekworm-raspberry-pi-ups-x728-v2-3-max-5-1v](https://www.desertcart.kg/products/487149966-geekworm-raspberry-pi-ups-x728-v2-3-max-5-1v) --- *Product available on Desertcart Kyrgyzstan* *Store origin: KG* *Last updated: 2026-05-02*
