I am planning to run local AI workloads on a Raspberry Pi 5, but I am concerned that the system will crash due to the brief switching delay when wall power is lost. Could you suggest which of the UPS models offer true zero-delay switching to keep the Pi alive during these sudden power cuts? Thank you.

We recommend the PiPower 5.
