The Nitecore T4K offers an extraordinary opportunity to own a compact powerhouse that fits right on your keychain. As the world’s most compact 4000-lumen keychain light (with a 10-second turbo burst), the T4K delivers impressive illumination reaching over 228 yards. Despite its thumb-sized frame, it is packed with advanced features, including a keyring with a built-in mechanical quick-release design for rapid deployment. Along with the included adjustable pocket clip, the T4K is the perfect everyday carry (EDC) companion, ready for any emergency kit or outdoor adventure.
Operation is intuitive and user-friendly with a familiar dual-button layout. One button powers the light on and off, while the mode button cycles through five brightness levels to suit various needs. The mode button also serves as an instant turbo switch, allowing you to access maximum output whether the light is on or off. This makes the T4K not only powerful but also extremely easy to use, making it an essential tool for everyday carry, outdoor activities, and emergency preparedness.
Charging is fast and convenient thanks to the built-in USB-C port, which fully recharges the T4K in under 1.5 hours. Once charged, the light provides an impressive runtime of over 67 hours. The multifunctional OLED display continuously updates you with real-time information about battery level, output lumens, runtime, and charging status. To extend battery life and enhance safety, the T4K includes two lockout modes, multiple charging safeguards, and advanced temperature regulation. Its rugged design features an IP54 weather resistance rating and a heavy-duty keyring rated to hold up to 66 pounds, making it durable enough for everyday use and tough environments.
The T4K features four CREE XP-L2 V6 LEDs capable of producing a maximum output of 4000 lumens during turbo mode. Its total reflective optic system ensures a smooth, uniform beam with a peak intensity of 10,900 candela and a maximum throw distance of 209 meters. The built-in 1000mAh Li-ion battery supports stable current output for extended periods, enhanced by an advanced power cut-off technology that minimizes standby power consumption. Users can choose between two operational modes—Demo and Daily—to fit different usage scenarios, and the intelligent mode memory function recalls the last setting for convenience.
Crafted with a HA III hard-anodized finish, the T4K is impact resistant up to one meter, combining toughness with sleek, compact styling. Its dual-side switch design offers quick access to five brightness levels and turbo output, all managed through a single hand operation. With a metal ring pull capable of withstanding up to 30 kilograms, the T4K is built to last while delivering outstanding performance wherever you go.
Included in the package are the T4K flashlight, a USB-C charging cable, a key clasp, and an organizer, making it ready to accompany you on every adventure or daily task.
