RhineStun Keychain Stun Gun – 4.5mA, 120-Lumen Flashlight

Most people don’t forget their keys. That’s the practical argument for a stun device that clips directly onto a keyring. The RhineStun Keychain Stun Gun measures just over 3 inches and weighs 0.35 lbs—small enough to live on a keychain without pulling it down, and always present because your keys are always present. The rhinestone coating that gives it a decorative look also creates friction across the grip surface, which matters more than it might seem in a stressful moment.

Who This Keychain Stun Gun Is For

This is for people who want a self-defense option that travels with them automatically, not one that requires a separate daily decision to bring along. It fits people who commute, walk to parking structures, work late shifts, or move through spaces where they’d rather have something accessible than not. The rhinestone finish means it reads as a decorative accessory on a keychain rather than a piece of safety equipment—which suits anyone who prefers their gear to stay low-profile. It’s not designed for people who want distance capability or a device with a dedicated holster carry system as a primary method.

Is It the Right Fit for You?

Choose It If You Want

• A stun device that attaches to your keyring and requires no extra carry step
• A textured grip that resists slipping, even under stress
• A built-in 120-lumen LED flashlight for everyday low-light use
• A dual safety switch to prevent accidental activation on a keyring

Consider Another Option If You Need

• Any distance from the other person—this requires close contact to function
• A larger grip or more substantial form factor for easier handling
• A dedicated holster-carry device rather than keyring attachment

RhineStun Keychain Stun Gun Features and Benefits

• 4.5 Milliamp Output: Delivers meaningful electrical current in a device this size—milliamps, not just voltage, determine electrical delivery.
• 120-Lumen LED Flashlight: Bright enough for practical use—checking a back seat, finding a keyhole, or lighting a path—built into the same device.
• Rhinestone No-Slip Grip: The textured coating creates friction across the entire grip surface, helping maintain control when fine motor skills are compromised by stress.
• Dual Safety Switch: Requires two deliberate actions before activation, reducing the risk of accidental discharge while bouncing around on a keyring.
• USB Rechargeable Battery: Built-in rechargeable LiCo battery charges via included cord—no replacing disposable batteries.
• Keyring and Nylon Holster Included: Two carry options in the box; attach to keys or clip the holster to a bag.
• Compact Dimensions: At 3¼” x 1½” x 1″ and 0.35 lbs, it adds minimal weight and bulk to a keychain.

• RhineStun Keychain Stun Gun (available in Pink or Silver)

Charging and Care

The built-in rechargeable battery charges via the included USB cord.

RhineStun Keychain Stun Gun: Frequently Asked Questions

How many milliamps does the RhineStun Keychain Stun Gun deliver?

The RhineStun Keychain Stun Gun delivers 4.5 milliamps. Milliamps measure the electrical current the device produces—this is the spec that reflects actual electrical output in a compact stun device. The 4.5mA rating is drawn directly from the manufacturer’s specifications for this model.

How do you charge the RhineStun Keychain Stun Gun?

It charges via the USB cord included in the box. Connect the cord to the device and plug the other end into any standard USB power source. The built-in rechargeable battery is designed to be topped off regularly rather than run down completely between charges. No batteries to replace or buy separately.

What does the dual safety switch actually do?

The dual safety switch requires two separate, deliberate actions before the device can activate. This is specifically designed to prevent accidental discharge while the stun gun is attached to a keyring and jostling around with other keys. It adds a brief extra step when you need it quickly, but reduces the risk of unintended activation during normal carry.

Is the rhinestone grip purely decorative?

No. The rhinestone coating creates friction points across the grip surface that help prevent the device from rotating or slipping in hand. Under stress, grip strength and fine motor control are often reduced. A textured surface gives the hand something to hold against. The decorative appearance is a side effect—the functional purpose is retention. It also makes the device read as an accessory on a keychain rather than a safety tool, which some people prefer.
