Most Powerful Keychain Laser Pointers

Laser pointers that fit on your keychain are usually small and pack a low punch in nanometers, which is the distance you would be able to see the laser clearly in complete darkness.

Executive Pro
The Executive Pro from Wicked Lasers is one of the most powerful keychain laser pointers on the market. It is cumbersome on the keychain, however, as it's a little over 6 inches in length.

PhysLink Laser Pointer
The Physlink keychain laser pointer is incredibly affordable at about $5 a unit and has a super bright range for its laser of up to 630 nm, or over 4,000 feet.

Mini Most Powerful Laser Pointer
The keychain $5 model of the Mini Most Powerful Laser Pointer has a standard wavelength distance of 650 nm and relies on a single battery to operate. It is more durable then the Physlink laser pointer and has an ON / OFF button as opposed to a push-button, so the laser life isn't as easily wasted.
