Hello, I have a new AC70 (just received 2 days ago) that I fully charged yesterday to 100%. Today I connected my 1 year old Samsung side by side fridge in a test to see how long it would run. Initially when I turned the AC on no power went to the fridge after about 5 seconds the lights came on. Then - I have noticed that when the fridge cycles off (compressor not running) the display shows 0 watts being used. How can this be when I open the door the lights are on so it must be using some wattage.
I have done this same test using my EB3A and Jackery 1000 and they show some wattage being used in the scenario above.
Should I suspect there may be something wrong with this new unit?
By the way, the fridge has been running since 6:45am and it is now 2:25pm at the charge is at 23% - not bad!
because the AC70 requires a minimum watt draw before it will display on the meter and you are pulling almost nothing with the led light bulb. I don’t know off the top of my head what the minimum watt draw is to be displayed. Nothing wrong with your unit.
My understanding of power banks is; when running an appliance such as a fridge on VAC and it cycles off, it is not consuming power. However the inverter is still running and using parasitic load, depleting the AC70. It may be that the smarts of the 70 include the low watts of the LED. The meter is only showing load you use, not the parasitic load of the AC70, BMS or inverter. I would think the time left display might, assuming this represents SOC of the battery and includes the hidden internal loads of the AC unit.
