Abstract: Quantum random batteries are devices that evolve unitarily by rotations in random directions in Hilbert space. The average work extracted is equal to the difference between the initial energy and the energy of the state at infinite temperature, times a quantum efficiency factor (1+Q/d^2), with d the dimension of the Hilbert space. The value of the parameter Q depends on quantum coherence of the evolution. This average behavior is also typical, meaning that the probability of extracting a different amount of work converges rapidly to zero with d
