   A 10 000 mAh powerbank fully charged contains 2 nanograms of electric potential.

   e = mc²

   10 Ah * 5 V = 50 Wh
   50 Wh * 3600 s/h = 180 000 J

   180 000 J / (300 000 000 m/s)² = 2*10⁻¹² kg

      Is that how the mAh rating on powerbanks works, or is the A meant to be at the internal voltage like 7.2 V or something?

      Why do they even use Ah? Use Wh instead and avoid this confusion.

      (the world is not ready for powerbanks rated in J)
