Despite its tiny size, the battery manages to achieve a 200-watt-hour-per-liter energy density, which is comparable to that of larger, conventional lithium-ion batteries.

    If the mars rovers can function on a fraction of a watt,

    It doesn’t?

    Perseverance’s power system works essentially like a nuclear battery. …The power system will reliably produce about 110 watts …The MMRTG also charges two lithium-ion batteries, … Perseverance’s power demand can reach 900 watts during science activities.

      Yeah, see!

      An RTG could power my phone!

      Sigh, let me spell my point out for you…

      What I mean is that I can absolutely believe that a solid state battery could power the next gen smart watch, I doubt it will.

      Just as an RTG could power my phone, but I doubt that it will be powered by it.
