World’s Brightest Keychain EDC Flashlight
Carry unmatched power in the palm of your hand with the Nitecore T4K, the world’s most compact 4000-lumen (10-second burst) keychain light. Despite its thumb-sized design, it delivers an impressive throw of over 228 yards. The built-in mechanical quick-release keyring allows fast deployment, while the included adjustable pocket clip makes it a reliable everyday carry companion. Featuring an intuitive dual-button interface with instant turbo access, the T4K is a practical addition to any keychain, emergency kit, or outdoor setup.

Simple, Familiar Operation
The T4K’s dual-button layout keeps things straightforward: a power button for on/off and a mode button to cycle through brightness levels. The mode button also doubles as a turbo switch—press and hold for instant turbo, whether the light is on or off. With five brightness settings to cover any situation, the T4K ensures versatility in a compact form.

USB-C Fast Charging
Equipped with USB-C fast charging, the T4K fully recharges in under 1.5 hours, offering over 67 hours of runtime per charge. Its OLED display provides real-time updates on battery status and charging progress. Two lockout modes help preserve battery life and prevent accidental activation. Built with charging safeguards, an IP54 weather-resistant rating, and a 66-pound rated keyring, the T4K is rugged, reliable, and ready for anything.
