Primordial black holes (PBHs) are one of the most interesting non-particle dark matter (DM) candidates. They may explain all the DM content in the Universe in the mass regime about $10^{-14}M_{\odot}-10^{-11}M_{\odot}$. We study PBHs as the source of Fast Radio Bursts via magnetic reconnection in the event of collisions between them and neutron stars (NSs) in galaxies. We investigate the energy-loss of PBHs during PBH-NS encounters to model their capture by NSs. To an order-of-magnitude estimation, we conclude that the parameter space of PBHs being all DM is accidentally consistent with that to produce FRBs with a rate which is the order of the observed FRB rate.
