An electroshock system wirelessly delivers a shock to a subject. The electroshock system may include a launcher, a wireless projectile, a power source, and a wireless power transmitter. The launcher is configured to be grasped by a user. The wireless projectile is configured to detach from the launcher and adhere to a subject. The power source contributes power for the administration of a shock to the subject. The wireless power transmitter delivers said contributed power to the wireless projectile while the wireless projectile is detached from the launcher. The power source and the wireless transmitter may be co-located with the launcher, or may be separate (such as secured to a person or within a vehicle).
