There is a bug somewhere in my APC where it drops and reconnects USB at <br>
random. Also during a power failure! I see those in the syslog every <br>
few days. A similar problem on the EcoFlow seems like an odd coincidence.<br>

The 'Plus' models have USB-HID support and recent versions of NUT know how to talk to them. I have at least 4 times as much runtime now (using a 2kWh EcoFlow unit) and it takes less space and is silent at my load level.<br>
