This maximum strength stun gun delivers a 1.552 microcoulombs charge, helping to temporarily incapacitate an attacker by causing intolerable pain according to the Department of Justice (DOJ), allowing you the opportunity to escape to safety. A built-in 120-lumen LED flashlight lights your way to safety in emergencies or for everyday tasks such as walking the dog at night. Unlike other stun guns, the S-1021 features a battery strength indicator so you know when you need to charge your stun gun, increasing its reliability. It also has a safety switch to help prevent accidental discharges while not in use, and its built-in battery and included charging cable allow the stun gun to be used multiple times.
