PiJuice Portable Power Platform for Raspberry Pi

Allows for different options for power, adds UPS using supplied battery or add your own. Also includes real time clock and options for booting up on a schedule, useful for remote devices that might need a nightly reboot to help prevent locking up.

I like that this hat fits well on the Pi and it also has pins so that another device can be hatted on top. I also like that it has external power pins. The only thing that I don't like is that there doesn't seem to be any way of powering it on physically without using the tiny buttons. Yes, the buttons are programmable, but it would be great to be able to hook up an external power switch. If there is a way of doing that, I'm not aware of it. The vendor should have the option to buy it with a stronger battery.

It has many more features than most other RPi UPS hats you can buy now and days. Able to perform basic functions such as automatic charging and poweroff. Take a look at the Github website, very helpful support. Pros: 1. Good GUI....... no complaints there 2. GPIO integrated... 3. Many features.... Cons: TBD

Con: they say like 2.5 hour battery life, it's more like 40 min only powering a PI4b and a USB thumbdrive. Really that wasn't important to me, because I set it to power off after 6 min, but if your using it to run without power, your in for a surprise

Issue with first Pijuice Hat: battery would only power the PI for 10 seconds than crash. The PiJuice power level was 88%. Issue with Second Pijuice Hat: board will not recognize the battery. "COMMUNICATION ERROR". no Leds light up when connected to Pi I've done my due diligence and researched the git repo discussion boards to no avail.

This is a very useful hat for me because of the frequent power outages.

For the premium price, fit and finish is lacking. GPIO header and 2 more connectors on the PiJuice are crooked. The tilted GPIO header means the hat hits my case - I will have to shim it or run it off a ribbon cable. Dip switch on board is squashed. GPIO pins also appear lesser quality than the ones on my Raspberry Pi 4. Does not inspired confidence. I paid extra for this vs. the several inexpensive alternatives to keep money at home and out of the hands of the bottom-dollar foreign shysters. We gotta do better than this, boys. Oh, and if I was choosing, I'd rather have rechargable AA's or 18650 batteries and the option of 12V input. I want to make a solar powered setup but it will have to have an intermediate step, like a solar charge controller and separate 12V USB charger.

Gives good up time when in the field so that contacts can be logged and gives the ability to have safety shutdown if I forget that the battery is getting low. This way I don't risk damaging the Pi or the Memory Card.

This is probably one of the best UPS hats on the market, the unit is configured by a GUI to support the button presses and control the on board LED. Other HATS are available however use standard 18650!batteries or an external Lithium Ion battery. The latter can be a plus if you need more than a few hours of backup. The on chip battery is in the form of a common mobile phone battery. One should note that it is quite easy to brick the SD card by removing the power to the PI without an orderly power shut down an as such any backup HAT with a power down button that shuts the Kernel down properly is always going to be a wise addition.

I ordered this portable power supply for my Raspberry PI to perform range testing for a LoRaWAN solution. Battery lasts a long time and has a lot of options to program behaviours. I recommend the product.
