Bought an EcoFlow last november, 2048Wh capacity. My fridge uses about 1.2kWh/day so I figured I'd get close to 40 hours. Got 19 hours. Put a kill-a-watt on it and found the inverter pulls 22W idle even when the fridge compressor is off. Over a day that's 530Wh wasted on nothing, about 25% of the battery gone before the fridge even runs. If you're shopping for fridge backup look at idle draw first, not the Wh number on the box. It matters way more than capacity for this use case. submitted by /u/Critical-Host2156 [link] [comments]
