Can it power a fan?** A: This position is for more batteries. You can’t power the fan. **Q: How do i program "back-to-ac auto power up"?** A: The technical support website: https://wiki.52pi.com/index.php?title=EP-0136, your consultation is available at 7.13 options. **Q: Can you please recommend batteries with which the ups board works. if possible please with a link to the batteries.** A: Two single-cell 18650 batteries are recommended. **Q: Does the black version fix the charging issues so that it does not die over night, even when plugged in?** A: the version i bought a couple of months ago is plugged in all the time. no problem at all. when i disconnect the power source (just tried it tonight to be sure) it powers from battery without being interrupted. so it works great. 32.6 degrees C; not overheated, but i've installed a geekpi tower cooler ## Customer Reviews ### ⭐⭐⭐⭐⭐ Has been rock solid since March 2021, also works on RPi5 *by L***Z on January 13, 2024* I put this into service for my 2GB RPi4 running Home Assistant in March 2021. Since then it's been rock solid, weathering multiple power outages and device relocations. Moving to an 8GB RPi4 now that they're in stock (thanks jeffgeerling dot com from rpilocator dot com), but also picked up a RPi5 and tested it first. Worked perfectly, just like on the 4.What it does well:* Gives you a UPS on your Pi. Easy to connect, needs M2.5 screws/standoffs.* Keeps pi running whether power is connected or not. Seems to last a long time, did not test.* Gives you an easy power button.What it could use:* A way to monitor usage through the Pi OS / Linux.* A mounting plate with the pressure springs or a wire, the POGO pins are awesome but no case.* A case for it w/the Pi. I really like the Orange Pi all metal cases.* It could be cheaper. I'd buy 10 of these if they were < $15. ### ⭐ Kills battery while "off" and then won't charge *by D***O on April 14, 2024* If you leave this "off" for an extended time (weeks), it discharges the battery completely. Then it automatically turns on the Raspberry Pi while it attempts to charge, but then turns it off again -- repeatedly.Since it's a push button on-off switch, there is no way to lock the Pi off while it attempts to charge ### ⭐⭐ Worked, for a while... Cannot recommend. *by B***K on February 11, 2024* I really wanted to like this UPS unit... First notable problem is the software gives you no control over how the batteries are charged. You can write any values you want to the unit, it makes no difference. The unit never stops charging the batteries on a continuous basis as long as power is supplied to the unit. Second problem, the unit has never provided steady 5 volts to the outputs, despite input voltage being around 5.25v from a Raspberry Pi power supply. Output voltage from the UPS has always varied between 4.5 to 4.9 volts, and my Pi 3 B+ won't run stably anymore due to this. I've been using this UPS unit for a little over 3 months with a pair of Sanyo 2500mAh batteries that are known to be good (and do in fact keep the Pi powered without AC mains for well over an hour in this UPS unit), and while in the beginning everything worked well and stable enough, in the last two weeks, the Pi has been rebooting itself more and more frequently to the point where the Pi isn't staying up for more than 6 hours at a time, pointing to a deteriorating UPS output power supply output. Load has not changed in the time the UPS has been in use, it's just the Pi and an MCP3008 with four TMP36 temperature sensors, so I cannot reasonably believe the issue is my loading of the UPS. I wanted to like it, but it looks like unless I can figure out how to raise the UPS unit's output voltage to a reliable level, I will not be using this anymore. For the price of this thing, I expected far better. --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tw/products/283305726-raspberry-pi-4-ups-plus-power-supply-uninterrupted-ups-hat](https://www.desertcart.tw/products/283305726-raspberry-pi-4-ups-plus-power-supply-uninterrupted-ups-hat) --- *Product available on Desertcart Taiwan* *Store origin: TW* *Last updated: 2026-05-19*
