SunFounder PiPower Raspberry Pi UPS Power Supply, Protect The Raspberry Pi and SD, 5V/3A, Expansion Board, Compatible with Raspberry Pi 4B/3B+/3B/Zero 2 W/Zero W (Battery Included)

This is a great (and necessary), addition to my project, a small, portable, retro gaming device. The instructions were clear and simple, and there were no issues installing the power supply to the bottom of my Raspberry Pi. The battery pack is a little chunky relative to the RPi, but it does have feet on the bottom which is a nice feature. If you plan to make your Raspberry Pi independent like I did, make sure your screen goes on the top, or else it will be incompatible with this power supply.I hope SunFounder releases more of these power supplies, maybe some a little smaller or lighter. I'm not complaining though. This was a great purchase!

I have three RPi's running specific tasks that would cause some concern if the power failed. If nothing else, power failure often trashes the SDC chip, the Pi is running on. While , I constantly update/clone the SDC chips, I've lost data because of power blinks. That's when, somewhere down the line, a switch was thrown, a generator cut over, or whatever causes the power to cut off, and immediately comes back on and your SDC is trashed. One of my Pi's is plugged into an APC UPS, but two of them sit where putting even a small UPS would be a hassle.I got one of these SunFounder UPS's and put it on a test RPi. It's a good little kit, but could be a great kit. They give you extra parts and, even, a screw driver to put it together. So it goes together very easily. On the downside, this configuration makes it hard to put the Pi in a case, without some jury rigging. But, whenever you add hats to a Pi, you lose a lot of case capabilities.When you download the software SunFounder provides, you can check the status of the UPS. If you make the connections to the GPIO bus, Then you can load a script that shuts the Pi down when the battery gets to low. The downside is that you have to solder the wires to the UPS hat and then have connections for the GPIO header. Luckily I did, but everyone might not. It would be better if SunFounder put a connection header on the IO ports for the UPS.I've tested everything but the graceful shutdown, if the battery gets too low. I've been to busy with the Pi to get to that. Everything else works as it's supposed to. I have run the Pi for over two hours on battery alone, and that was while the Pi was actively performing functions.I'll be ordering a couple more of these to put on my dedicated Pi's. I just need to figure a case for them. Two of the Pi's sit where they are exposed to dust.UPDATE:I just got my first RPi 5. Naturally, I hooked it to power through the UPS. Unfortunately, within about 10 minutes, I got the low power popup. A few seconds later, the RPi shut itself down. I had heard that the powerbank UPS's didn't have the current required to run an RPi 5, but I had to try.That's OK for me, I'll probably go with an AC UPS to power the RPi 5's. I still have two RPi 4's sitting up in corners, where the Sunfounder works great.Pros -- It works Easy to put together Kit has spare partsCons -- Not powerful enough for RPi 5. No available cases for this configuration. Important feature requires soldering on the UPS IO ports. Needs a header to make it a great kit. For this I dropped a star.

While this product is marketed directly for Pis with some jerryriging you can use this with other boards. With some particular modifications this was able to fit an OrangePi 4 LTS and power it perfectly fine without any issues. So imagine it with the product it's designed for.

One of the cables was missing, I contacted the company and I received a superb customer service. Susan answered right away and shipped me the missing cable for free immediately.The product looks very well made. I still have to use it some more, but so far so good.

This is a really nice UPS board and I do like the way it went together. It was not difficult to assemble or to attach to the Raspberry Pi. It included both micro-USB and USB-C jumpers to power the Pi from this board. However, there is one glaring flaw. There is no way to connect the board to the Pi's GPIO header unless one fabricates a jumper and solders wires or some form of connector to the 9 position header spot on the side. I chose to use a 9-pin plug-in screw terminal block connector. I soldered that in and then could use the screw terminals to attach wires for a jumper to the GPIO header. Why such an attachment block was not there already is beyond me. Why a jumper cable to use to attach to the GPIO header was not included either since one can't get the shutdown functions to operate without such a jumper.On a positive note, PiPower does provide information about how to set-up and configure automatic shutdown. The details on how to get, install, and configure the script are straight-forward. That re-gains them one star. Kudos to PiPower for providing this. This board lacks an auto-restart feature but PiPower did communicate that a Pro version is in the works that will have that functionality also. Hopefully, the issues above will be addressed also.It is working well and does adequately support a Raspberry Pi 4B that is running a digital communications node. When power is cut, the Pi keeps working. I did have one time where it did shut the Pi down and there was no corruption of the SD card because it was protected. Therefore even with the faults, I can recommend this as an option for someone wanting to keep a Pi running when the power goes out.

The device is exactly what is being advertised.

The battery lasts only 6 mins and the dies. Additionally the cheap plastic posts that elevate it from the base are easily broken. Could be that I got a bad unit, but it’s currently a brick. I will exchange this one and amend my review if that is the case

Assembled and ready to go, just haven't installed it yet

Buen UPS, justo lo necesario para proteger mi Raspberry Pi de los ocasionales apagones y es más barato que un No break tradicional.

As can be observed in the photographs, it is possible to simply reverse the direction of support components (support "thingies" between acrylic and board parts) and utilize the cooler with the RPI.I have not tested it enough to tell you how long it can maintain RPI's supply of power. Other than that, it's cool and quiet (I mean, I'm not even sure that there could be "coil whine" it this kind of board).It looks almost like a Christmas tree when it’s dark. Would recommend.

Acheté pour une Raspberry avec un disque dur relié. Approuvé à la première tempête.Je le recommande vivement.Autonomie presque 6 heures.

Works perfectly. Fitted to a Pi 3B to protect against intermittent power outages. It has a USB-C connection for power and the 3B official power supply is a micro USB connector so I had to buy an adapter. Once the adapter was fitted, it has worked without any problems.
