Pocket Keychain comparison with the T4K and other models.
Unparalleled size and performance compared to any keychain lights in the market.
BLINDING 4000 LUMEN TURBO - This amount of instant blinding brightness will disorientate anyone in front of you. Intended for momentary use, this is perfect for emergencies or wide-area illumination.
REAL-TIME OLED DISPLAY - Battery anxiety is no longer a worry for pocket lights. With real-time brightness and power display, there's no need to second guess how much run-time is left.
EASY ONE-HANDED OPERATION - No complex twisting, brightness can be changed with just one push of a thumb. Press and hold the mode switch for turbo or to cycle through the 4 brightness levels with short presses on the mode button when the light is turned on.
DEEP POCKET CARRY CLIP - Made with reliable usability in mind, using the deep pocket carry clip, the T4K can be mounted on a cap to use, enabling hands-free lighting with a simple clip-on. The deep pocket carry clip also acts as a strong fastener for the T4K when mounted to backpacks for all your user needs.
BUILT-IN QUICK CHARGE PORT - With high power, comes a need for fast charging. The T4K comes with a in-built 1,000mAh battery which will take approximately 90 minutes to charge, which is incredibly fast for a light this powerful and compact. Additionally for extended use, the T4K can be charged and used at the same time, making it a great option as an emergency or backup light.
READY FOR ANYTHING - Weatherproof and compact, the T4K can take on any situation Advanced Temperature Regulation (ATR) technology ensures optimal performance based on the environment's temperatures even for a compact carry.
The smallest, most powerful keychain light is here, it's the T4K.
Nitecore has been making lights for professionals and daily-carry users for some time now. Over 15 different international agencies have Nitecore as their standard issue. So they know exactly how their lights are used, the increasing challenges that people on the ground face and what's expected of reliable gear.
Now there are many, many lights that market themselves as compact and bright lights. If you're a new user, it's quite impossible to tell the difference lumens-wise. Most keychain lights feature brightness that's just merely usable but market themselves to be of super-high brightness. Additionally, they're not made for long run times or for small extensive uses where it counts.
The Nitecore T4K was made to be a bridge between heavy-duty lights and smaller portable keychain lights, the best of both worlds. With the size of a thumb and boasting the same brightness as our flagship light, the T4K is no doubt a must for anyone's everyday carry.
If you've been looking for the most powerful everyday-carry light for 2023, don't miss this bundle light with amazing bonus items.
