Thanks to the 10 seconds burst of 4000 lumens light, the Nitecore T4K is claimed to be the world’s brightest and the most compact keychain night. 

It comes with a built-in 1000 mAh rechargeable battery and a USB-C fast-charging port. It fully charges in under 1.5 hours and provides over 67 hours of effective runtime.

Being a compact keychain, the Nitecore only weighs about 76.3 grams with 25.2 mm thickness and 36.34mm length.
