Zero2Go Omini: Wide input range, multi-channel power supply for Raspberry Pi

Zero2Go from UUGear is a small Raspberry Pi Zero sized (or pHAT shape) extension board that can work as a smart power supply add-on for Raspberry Pi. Zero2Go Omini supports all Raspberry Pi models that have the 40-pin GPIO header, including A+, B+, 2B, 3B, 3B+, 3A+, Zero, Zero W and 4B. Zero2Go has quite wide input range (3.5V~28V), so it is convenient to power your Raspberry Pi with power bank, Li-Po battery pack, solar panel, car battery or different kinds of power adapters etc. You can also configure it as a UPS (please read user manual for more details).   Free shipping on this product!   Features Three separated input channels (each accepts 3.5~28V DC). Auto step-up or step-down to output 5V for powering Raspberry Pi. Auto switch input channel (one with highest voltage takes the priority). Gracefully turn on/off Raspberry Pi with single tap on the button. Fully cuts power for Raspberry Pi and all its USB peripherals after shutdown. Long hold the button to force power cut, when OS loses response. Monitor the input voltage on each channel (via software). Shutdown Raspberry Pi when input voltage below preset threshold. Recover Raspberry Pi when input voltage exceed preset threshold. Notes Zero2Go Omini does not charge the connected battery, and you may need external charging circuit like this one. User manual
