The Nitecore TM20K is a high-output flashlight with up to 20,000 lumens on Turbo and a maximum rated beam distance of 290 metres. Turbo is a hold-to-use setting for brief demands on maximum brightness, not a continuous 20,000-lumen mode. Temperature regulation limits output, and releasing the tactical button returns the light to its previous state.

Two built-in 21700 Li-ion batteries recharge through the flashlight’s USB-C port. They are not user-swappable, so charging access is part of planning for extended use. Lower brightness settings provide alternatives when a Turbo burst is unnecessary, with published runtimes measured under laboratory conditions rather than guaranteed in every environment.

  • Low is rated at 1,050 lumens for 4 hours 15 minutes with the built-in batteries; output and runtime vary in use.
  • Charging takes approximately 4 hours 30 minutes with a compatible QC adapter, or 7 hours 30 minutes at 5V/2A.
  • The flashlight switches off when connected for charging and ships in Lockout.
  • IP68-rated to 2 metres. Do not immerse it while hot.

Frequently asked questions

Is 20,000 lumens a continuous mode?

No. Turbo is a hold-to-use mode, and temperature regulation limits output. Release the tactical button to return to the previous state.

What runtime can I expect below Turbo?

Low is rated at 1,050 lumens for 4 hours 15 minutes; Ultralow is 320 lumens for 13 hours. These are laboratory figures, and output varies in use.

Can I replace its two 21700 batteries?

They are built into the flashlight, not user-swappable cells. Recharge them through the USB-C port.

How long does charging take?

Approximately 4 hours 30 minutes with a compatible QC adapter, or 7 hours 30 minutes with a standard 5V/2A adapter. The light turns off when connected for charging.

Why will it not turn on straight out of the box?

It ships locked. Hold the Mode button while sliding the selector from the lock symbol to position 1 or 2 to unlock it.

Can it handle wet conditions?

It is IP68-rated with a 2-metre submersion specification. Do not immerse the light while it is hot.

Are all products authentic and genuine?

Yes—all items are factory-original units sourced through trusted channels. We never sell replicas or knockoffs.

How do I verify a product’s authenticity?

Genuine items include authenticity markers—scratch-off codes, serial numbers, official packaging. Verify codes on the manufacturer’s site. We only list authentic gear.

Do your products come with warranty coverage?

As these products are shipped globally and sourced through various channels, manufacturer warranties may vary by region. However, we stand behind everything we sell—if an item arrives defective or develops an issue shortly after delivery, we’ll work with you to resolve it quickly and fairly. Our goal is to ensure you receive fully functional, authentic products—no compromises.

How long does shipping take?

Estimated total delivery time, including order processing, is generally 10–17 working days, depending on the product, supplier, shipping method and destination.
