AC70P Discharge Rate?

I’ve been testing my AC70P powering my 12 volt cooler set at 40°. The AC70P powers the fridge for 3 days using 75% of the AC70P. The last 25% of the AC70P runs the fridge for 12 hours, so that 25% discharges twice as fast as the first, second, and third 25%. Is this normal or expected?

Hi @MisterK, Since coolers adjust their power in real time based on actual working conditions, testing with a cooler can be affected by these fluctuations. We recommend using a purely resistive load, such as a hairdryer or a heater, for testing instead.
We also suggest recalibrating the battery before trying again.
Please follow the steps below:

  1. Please discharge all the power (charge AC & DC appliances with the power station till it is out of power and turns off automatically);
  2. Please charge it again, please do not load any device when charging it, and do not interrupt it while in charge.
  3. Once the power is 100% fully charged, turn off the machine, and leave it the whole day.

Please let us know if it does help.

I tested my AC70P on my 12 volt fridge in a static environment without any food or anything else in the fridge. I did it twice with the same results of discharging, and I have recharged my AC70P twice using the method in your steps 1, 2, 3.

Hi @MisterK, we suggest you test the AC70 with some other appliances, such as a light, fan or so on, because coolers adjust their power in real-time based on actual working conditions, do you agree?

I will run a test using a fan and then I will report back the results. Thanks

I ran the fan test today. It shows my AC70P discharges at close to an equal rate per minute all the way to full discharge under that load. I say all is good. Thanks.
