The TM20K Rechargeable Tactical Flashlight is the brightest of the Nitecore Tiny Monster series, yet still remains compact in size. This high-performance flashlight is equipped with 19 LEDs for a powerful 20,000 output and can be used for anything from outdoor recreation to industrial uses, self-defense, or search and rescue. When connected to a USB-C QC (quick charge) power source, its two built-in batteries charge fully in 4.5 hours.

A toggle switch on the tailcap locks the TM20K for transport or carry, and you can set it to daily mode for constant-on or tactical mode for momentary. The large dual paddle switch provides instant turbo on one side and instant strobe on the other. The mode switch is used to cycle through brightness settings while the light is on, including spot and flood modes. The TM20K comes standard with all the advanced features you expect on NITECORE flashlights including IP68 rated waterproof, advanced thermal regulation, mode memory, and lockout mode.

Related Questions and Answers

Q: 1. Can this be powered by a power bank and if so, what are the minimum output requirements for the power bank in order to charge the Leica battery at full speed?

A: As per the manufacturer, you can charge your battery when this charger is connected to a USB power bank. A suitable option would be the Tether Tools Rock Solid 10,000mAh External Battery Pack, B&H # TERSBP10. https://bhpho.to/2x7scrM

Q: 2. I tried using this charger to charge AA and AAA eneloop NiMH batteries. They get VERY hot. So hot that I stopped the charge because I was worried the batteries were being damaged. Has anyone else had this issue? Is this normal?

A: This charger is for high amp dicharge batteries that have a low internal resistance ! Time to charge is 3 hours max.Eneloop charge in about 10 to 15 hours on a charger made for high IR at a much lower amp

Q: 3. What's the min and max watts of power this charger can handle?

A: The Nitecore USB Travel Charger for Leica (Leica's BP-SCL4 Battery) (B&H# NIULSL) is listed as having a maximum output of 8.4V at 1000mA. As such, there wouldn't be much point in attaching anything more than a 10W charger to it. Typically, that would be a common 2Ah (or 2.1Ah) 5VDC USB charger. Sometimes 2Ah is listed as 2000mAh (or 2.1Ah is listed as 2100mAh), but those are the same. Anything more would not result in faster charging, at least according to the specification given by the manufacturer. Please note that while some chargers (especially those with a Power Delivery feature) can charge at a higher voltage, only 5VDC should be used with this charger.

Q: 4. How do you get the batteries in and out of the unit. I don't see a way to open it?

A: This product is made from a flexible polymer which will allow you to squeeze the batteries out as needed.
