Anyone who uses 10000 mAh power bank? How many hours does it last in real use ?

Ok. I tried. Nano in stand by (just on ) I got 8 hours. Normal use maybe 4-5 hours.

Hi there,
There is a simple calculation you can apply:

        WorkingHours = BatteryCapacity (mAh) / QC_consumption (mA)

The QC is rated 12V at 3A (36W), this is nominal, The ral power consumption is about 14W to 16W,
Lest consider the case is 16W, P(W)=I(A)*V(V), then you get:

  I(A) = P(W)/V(V) = 16/12 = 1.33 (A) => 1330 mA

Then you can apply:

WorkingHours = 10000 (mAh) / 1330 (mA) = 7.51h

So it would las 7.5 hours

Consider the works case it consumes 36W @ 12V @ 3A (the nominal consumption declared in the manual)
Then you get:

WorkingHours = 10000 (mAh) / 3000 (mA) = 3.33h

So it would las 3.33 hours

I was talking NANOCORTEX. But thanks any way.
I have enough info. I also asked AI. I think it gave 4,5 hours /normal use.
