Nitecore E4K flashlight - Compact power for all adventures

Imagine you are in the middle of the night deep in the countryside or on a tactical mission. Your surroundings are shrouded in complete darkness and you need a reliable light source that is not only powerful but also easy to use. The Nitecore E4K flashlight is exactly the tool you need in such situations. This compact EDC flashlight combines state-of-the-art LED technology with a rugged design and versatility to give you the light you need anytime, anywhere.

outstanding luminosity - 4400 lumens in the palm of your hand

The Nitecore E4K impresses with its enormous luminosity of up to 4400 lumens, which is generated by the 4 CREE XP-L2 V6 LEDs. This brightness is enough to bathe even the darkest surroundings in bright light, whether for outdoor adventures, rescue missions or everyday tasks. Turbo mode allows you to use the maximum output of 4400 lumens for around 30 minutes, while High mode (1050 lumens) is designed for longer operations of up to 3 hours and 15 minutes. For everyday applications, the mid mode (320 lumens) offers a runtime of around 7 hours and 30 minutes, and the low mode (50 lumens) shines for an impressive 45 hours. The ultra-low mode with 2 lumens allows you to use the flashlight for up to 700 hours - ideal for long nights outdoors.

User-friendly one-button operation

The Nitecore E4K is not only powerful, but also extremely user-friendly. The one-button operation makes handling simple and intuitive, allowing you to quickly switch between the different light modes. This feature is particularly handy in stressful situations where you need to rely on your lighting tool without having to think long and hard about how to operate it. Whether you want to activate strobe mode, SOS mode or the beacon light - all you need to do is press a single button to select the desired mode.

Powerful 21700 Li-Ion battery for long runtimes

At the heart of the Nitecore E4K is the NL2150HPR Li-Ion battery with a capacity of 5000mAh. This battery not only provides impressive lighting power, but also long runtimes that won't let you down on longer outdoor adventures or tactical missions. The battery can be charged directly via a USB-C connection, which makes charging quick and easy. If you don't have the rechargeable battery to hand, you can also operate the E4K with 2 CR123A lithium batteries or 2 RCR123 Li-Ion rechargeable batteries thanks to the supplied battery magazine - flexibility that can make the difference in many situations.

Robust design for the toughest conditions

The Nitecore E4K is designed for use in extreme conditions. The housing is made of aerospace aluminum, which has been HAIII hard anodized to make it particularly resistant to shocks, scratches and corrosion. The flashlight is waterproof to IP68, which means that it is not only protected against dust, but can also be used under water up to 2 meters deep. Thanks to the ATR temperature control, the E4K remains safe even during prolonged use by preventing overheating and optimizing performance.

Versatility and accessories for all requirements

The Nitecore E4K comes with everything you need for immediate use. Included are a USB-C charging cable, a lanyard, a clip, a spare sealing ring, a holster and a battery magazine.
