Uninterruptible Power Supply UPS HAT for Raspberry Pi Series Boards(Raspberry Pi 4 Model B/3B+/3B) Charge and Power Output at The Same Time,Multi Battery Protection Circuits

Works great for raspberry pi cell phone project

the power switch and power input jack hang off the edge of the hat. Making it impossible to fit into an existing RPi enclosure. This isn't the only RPi Hat with this problem... sad.

Rating: ⭐⭐☆☆☆ (2 out of 5 stars)I recently purchased a Raspberry Pi UPS Hat, hoping for a reliable power backup solution for my projects. The concept of the product is promising, and I believe it could be a great asset if you receive a fully functional unit. Unfortunately, my experience was less than ideal. Despite trying various sets of 18650 batteries and utilizing the supplied charger to ensure they were fully charged, the unit failed to output any voltage. There was no 5V output from the USB, rendering the UPS Hat ineffective for my needs.I understand that defects can occur in any product, and I was initially willing to chalk it up to bad luck. However, my disappointment was compounded when customer service did not offer a replacement upon returning the defective unit. This has led me to reconsider my options, and though I still need a UPS solution for my Raspberry Pi, I’m inclined to explore other products instead of reordering the same model. For anyone considering this UPS Hat, I’d advise caution and suggest looking into the return and replacement policies beforehand.

Assembled and it does as it says. Works!

It seems sad that because of the power you have to have a UPS

Excelente 👌

it is working well
