Bluetti Apex300
We purchased Apex300 not for travel or RV purposes, but to provide a reliable backup power source for our pharmacy’s vaccine refrigerator. The critical requirement was uninterrupted power with 0 ms UPS transfer time to ensure the compressor never experiences a power loss during an outage. We tested the system multiple times by disconnecting the main power supply, and in every trial the refrigerator continued operating without interruption.
