Review on 🔋 PiZ-UpTime Pro 2.0: Ultimate UPS for Raspberry Pi, Pi Zero, SBC & IoT by Joe Griffin

After warning that the power supply is not looping (I taped my Raspberry Pi's micro USB PWR connector), PiZ works great. It supplies power through the pins of the GPIO connector. It works great even when installed with an Ozzmaker BerryIMU GPS device with the same GPIO connector. No battery is included, so you must use your own 3.7V lithium polymer battery. The battery's screw terminals mean you'll need wire strippers if your battery already has a JST power connector that needs to be removed.
