Stay protected without carrying bulky gear.

Traditional self-defense tools are big, obvious, and hard to access in a real emergency. The Suptruck Knuckle Stun Ring offers powerful protection in a sleek, palm-sized design you can carry anywhere—no one will even know it’s there.

Delivering over 28,000,000 volts with a simple squeeze, it features Squeeze-N-Stun™ tech for instant activation, no buttons required. It’s compact, lightweight (just 2.5 oz), and fits comfortably in your hand or pocket.

With a built-in rechargeable battery, the Suptruck ring stays ready for 30–45 days on standby—no extra batteries needed.
