  Consider that the energy output of a 12-gauge shotgun is approximately 4500 Newton-meters and, from personal experience, can rotate a first-gen iPad at an extrapolated 240 rpm (extrapolated as this priced difficult to sustain). That gives us an equivalent of 113 kW! A modern ipad would only need about 13 kW to charge in one second.

  So, one shotgun shell could easily charge yours and 7 of your friends ipads instantaneously, although the results are difficult to appreciate.

    I feel the Doc in Back To The Future vibe.

    Been charging my phone overnight for years. Battery health is 100% and I never have to worry about charging.

      Impossible for battery health to be at 100% after years. May still be working great, but not 100%.

        Battery degradation is ridiculously unpredictable. I’ve seen 100 cycle batteries at 75% and 2500 cycle batteries over 90%. I only dealt with like 5 MacBook models
