Nitecore NU33 Review (Red & White LED, 750 Lumens, USB-C)

Introducing the Nitecore NU33 Headlamp, a light designed for those who are wanting lightweight, small packaging, and multi-color emitters. The light features a primary cool white emitter (5867k), with an auxiliary neutral white (4575k) floody emitter and an auxiliary red mode. Thanks to Nitecore for sending this to me to look at and review.

Packaging & Accessories

The packaging here is Nitecore’s standard retail packaging. Inside the light is in a black plastic tray and has a few accessories. Included is the light itself, a strap that’s preattached, a USB-A to C cable, a manual, and a warranty card. 


Construction & Design

The NU33 has an aluminum outer shell, with a plastic bracket that the tilt mechanism and mount are made out of. It looks like it’s available in black and purple currently. The back of the mount is contoured a bit for comfort, and I will say this is one of the lighter-weight and more comfortable headlamps I have used in recent months. The strap is made of black elastic and is adjustable. The outside of it has silver markings for style and reflections around the entire way. It has tilt control, only down and about 75 degrees. The buttons on top of the light stand proud and have different heights and textures so they are easy to tell apart. The internal 2000mAh battery is sealed inside and non-user removable. 


Size & Weight

I measured the weight of the NU33 with the strap at 3.38oz, or 95.7g. length is 2.45”, width is 1.7” and it’s 1.34” thick. The light is only IP66 water and dust rated, which is less than we typically see. Light rain should be ok but I wouldn’t do much more than that. This headlamp compares nicely to some of the offerings from Blackdiamond and the like but I don’t have one of those so I picked a few headlamps to compare it to. 


LED & Beam

Nitecore doesn’t say which LED’s are specifically being used with the NU33. The main emitter is cool white but surprisingly neutral. On my Opple meter, I measured it at 5867k and 66 CRI and just slightly green with a good amount of tint shift. Its beam profile here is a defused spot, There is plenty of spill out of the optic as well. The axillary neutral white emitter measured at 4575k and 85 CRI. This is your short-range flood emitter, it’s pleasant but only good for short-range tasks as it only goes up to 53 lumens. One thing to note as well as there is no PWM here, it’s a constant current driver. 

Below are the outputs I measured with my Texas Ace Lumen tube. They measured slightly above what Nitecore claimed in all modes. My two comments would be I wish that the neutral white emitter had a high mode reaching 100 lumens and that the low had a lower output option instead of a blinking mode. 


Heat & Runtime

Runtimes for the NU33 were pretty good. Turbo is able to maintain its claimed 700 lumens for around 5 minutes while gradually ramping down. From there it was pretty flat out for 3.5 hours, before stepping down a few more times for a total runtime of 4 hours. As expected high gives you quite a bit more runtime out to 10 and a half hours, but the output is much less between 100-200 lumens during this time. For the other modes, I will have to take Nitecore’s word on the output runtimes as they were too long to graphically test. Auxiliary mode runs for 47 and 147 hours respectively and red is rated for 26 hours of runtime on its constant mode. 



UI here is pretty simple, the large power button is your on/off button (press and hold), once on pressing the button again quickly will change brightness levels. The other smaller round button is to change the emitter mode. To get to the blinking modes long press on the mode button when the light is on. The light does have lockout just hold both buttons together when the light is off for about 4 seconds and the main emitter will flash a few times to let you know it’s locked. 



The light does have a built-in non-user replaceable 2000mAh li-ion battery. Nitecore says this is equivalent to 3x AA batteries or 9X AAA batteries. The light recharges via a USB-C port on the bottom hidden behind a flexible plastic cover that stayed in place nicely. 

The total charge time I saw was 1:13:00 which is a little faster than Nitecore claims. Charge speed was under 1C but just barely for most of the charge and that’s probably why. There are 4 power level indicator LED’s on the left side of the light, each one representing 25% power and if the light is off you can just press the round mode button to turn them on. You can also use the light while charging. 



I was pleasantly surprised by this headlamp. It’s very light, yet feels well-built in the hand. It’s super comfortable to wear. I’m not a runner so I didn’t test that but I would expect it would do well here if you had the strap reasonably tight. I was pleasantly surprised the cool white LED here wasn’t cooler, 5800 CRI is workable, especially with the NW flood emitter for more up-close work. 


I will give it dings for the sealed battery, making it a disposable product and not very sustainable, as well as the red mode not having a low output mode. 18 lumens is fairly bright. 

I can recommend this one and think it’s a pretty good option for the average person. It’s probably not the best option for a flashaholic though. At the time of filming, the price is around $50 which is an ok value, you can certainly find this size of a headlamp for less with not as many features, etc and you can certainly spend more on similar lights from headlamps often used in the backpacking/climbing world running on alkaline batteries often. 


Let me know what you guys think of the NU33 in the comments below, if I have any discounts or coupons I will link to those in the description too. Thanks for watching this review, and supporting the channel, I will catch you on the next one.

Nitecore MH12S Review (1800 Lumens, USB-C PD, 21700)

Today I have the Nitecore MH12S, this is a new model in a long light of MH series lights from Nitecore. It’s marketed as multitask hybrid series light. It produces 1800 lumens, contains a 21700 battery that’s included and is USB-C PD rechargeable. Nitecore did provide this light to me to review.

Packaging & Accessories

The MH12 comes in a typical Nitecore retail package in the trademark black and yellow color scheme. Something that’s a little different is it doesn’t have the typical runtime chart on the back, only a long list of features, and on the side a list of use cases and accessories. Accessories included with the light itself is a 5000 Nitecore (non proprietary) button top 21700 battery, a 18650/CR123 Battery magazine, tactical holster, USB-A to C charging cable, lanyard, 2 spare o’rings, and a pocket clip, along with your normal paperwork. 


The MH12s is made from aluminum and anodized black. Machining & fit and finish are good, with no obvious problems detected. At the tail cap there is a quiet tall mechanical switch that protrudes and it takes some effort to actuate. The lanyard attachment point is on the rear tail cap and decent sized hole. Inside there is stiff springs at either end, and threads are anodized, fine and well lubricated. 


The body tube has minimal knurling but does have some on each end, you have 3 areas in the middle for the clip or tactical finger loop (not included) should you want. The body tube is glued to the head. There is a minimal anti roll ring at the front, it’ has limited effectiveness with anything but a flat surface.

The button (eswitch) on the head is aluminum as well, with a hole in the middle for power indication status, the button is relatively small and hard to find at night by feel alone, especially with gloves. There is minimal fins for heat dissipation. Opposite the button there is the USB-C charging port, the silicon cover here is well integrated and stays put without trouble. 

Up at the front there is a minimal bezel that does allow light to escape when standing on its head, it protects the anti reflective coated glass lens, and smooth bezel underneath. 


Size and Weight

I measured the overall length at 141mm, max diameter on the head at 29.5mm, minimum diameter on the body at 25.5mm. Weight with the included battery was 149.2g. The light is IP68 water rated and submersible to 2M along with the standard 1M of impact resistance.

It’s a long long light but within 5mm of the Thrunite TT20 and Olight M2R Pro, but narrower then both. 



The MH12S has quite a few retention options. It comes with a pocket clip, lanyard and a tactical hostler but is also compatible with a tactical ring that Nitecore offers separately. The pocket clip can attach facing either direction on any of the 3 ribs in the middle of the light. It’s not a deep carry clip as a good ¾ of an inch sticks op out of your pocket when put in the lowest position. My clip was slightly out of spec and doesn’t make contact with the body of the light. A little modification with some pliers should improve this situation but is a little disappointing to see on a brand new light. 

You also get a plastic belt holster that the light can be pushed into. You can put it in heads up or heads down, and it’s a tight fit. If done correctly at allows you to mount to access both the side buttons and top button from the holster. The lanyard attachment point should you choose to use that is on the tailcap. 

LED & Runtime

The light features a Luminis SST-40 W LED in cool white at 6500k. The good news here is that it’s not as blue as some older Nitecore lights which I appreciate. On ultralow and low power modes I get a slight green tinge but this disappears at higher power levels. The beam itself is small defined hotspot in the center and a large spill of less light. True to it’s name this is a nice all around beam, good for walking the dog, hiking, or more tactical uses if you wish. 

There are a handful of battery options here, the light comes with Nitecore 5000mAh 21700 battery, which will be most users primary cell, but with the battery magazine (Spacer) the light comes with it will also run 18650 and 2x CR123A batteries or RCR123. A battery capable of 8A discharge or more is needed to be able to access Turbo’s 1800 lumens or you will be limited to High’s 1050 instead. No PWM was present in this light, and I did verify this with my oscilloscope. 


Official outputs are listed as the following. 

  • Turbo – 1800 Lumens
  • High – 1050 Lumens
  • Mid – 300 Lumens
  • Low -50 Lumens
  • Ultra Low – 1 Lumen
  • Strobe/Beacon/SOS – 1800 Lumens


Heat & Runtime

I did my runtime and heat tests with the included 5000mAh Nitecore battery in uncooled conditions (More realistic). Turbo had a pretty quick step down from the 1800 lumens within the first minute and a half but it was a gradual step down and continued this trend from the 0:43:00 mark to 2:46:00 it was quite stable at 40% relative output, before it did it’s LVP warning and stepping down to 5% relative output and shutting off at 3:23:00. Max heat I saw during this time was 46C at 0:10:00.

I also ran a runtime test under the same conditions but only going to high mode, and here the light was able to sustain a much higher output for longer in comparison to turbo. Around 80% relative output or better for 3:26:00, with at total runtime of right at 4:00:00. So if you don’t need turbo this is the best mode to use for sustained output and runtime. 



The light has 2 modes, first the daily mode which is the lights default and how I tested and then a tactical function. When in daily mode the light does have a memory function for all modes except SOS and Beacon. When in tactical it will only memorize turbo or strobe. 


For daily mode the light turns on with the tail switch, and then you use the e switch up front to change modes, and it cycles through all 5 non blinking modes. There are no shortcuts to jump to turbo or turn on ultralow when off. If you press and hold the mode button when on the light will go to strobe instead of cycling through modes. It’s a little different from many lights but is easy enough to understand but might be hard to remember if switching to many other lights.



The MH12S has onboard USB-C charging, thats capable of being charged via USB-C to C and USB-C PD, another nice change to see. USB-C to C is finally going mainstream on flashlights. I charged the included 5000mAh Nitecore battery (non proprietary) from LVP at 2.947V to full at 4.198V in 3.5 hours. Max charging rate I saw was 1.9A at the 1:30 mark. The charging curve here looks a little funny with a lot of drops to near zero as detected by my meter, this also caused it to cut a little short the graph. I don’t think this is a problem for charging the cell just a bit different. The light will also charge 18560’s with the adapter if you want to. 


  • Simple interface but lacks shortcuts to moon or turbo.
  • Good all around beam
  • Not as cool white as past Nitecore Lights.
  • Wide selection of compatible batteries (21700, 18650, CR123A, RCR123A).



  • Seems long
  • Pocket clip did not make contact with the body without modification and it’s deep carry
  • Only one LED and tint option
  • UI has no practical shortcuts, requires cycling through brighter modes to go lower. 



The Nitecore MH12S is a solid general use light. I like that NItecore has taken a step away from ultra blue emitters but do wish they would offer a more neutral or warm tint option, in the MH series of lights since I believe these better represent the multifunction roll the lights were designed for. 

This isn’t a light I will probably EDC in my pockets due to the clip design and relatively long nature of the light, I do like it’s slim nature though. I think this is a better jacket pocket light or utilize the holster it comes with. The UI here isn’t my favorite but I can live with it. Overall I like the beam profile here of the light, and with the 21700 it has a great runtime, and it’s super great to see USB-C being implemented with full support and PD support. 

Nitecore NB10000 Review (10,000mAh, 18W USB-C, Carbon Fiber, Powerbank)

Today I have Nitecore’s newest powerbank the Carbon Fiber NB10000. It’s made from Carbon Fiber, all around, features 10,000mAh capacity, along with USB-C and A, and is capable of 18W input and output. Thanks to NitecoreStore for sending this to me to check out and review.

Packaging & Accessories

Packaging here is quite nice it’s a box that looks like it’s made of carbon fiber and it’s a pull out tray that has the powerbank, included USB-A to C cable, and the paperwork inside. 




This powerbank is made from a carbon fiber reinforced plastic case, this is a more expensive stronger material then you find in most power banks. It feels a lot like a high quality tool that’s using a glass reinforced plastic. As for the carbon fiber on the top and bottom, I have my doubts here on it’s authenticity. When I hold it up at a certain angle and press near the front I can get it to deflect easily, there is also no texture in the weave that I can feel. At best it’s a peel and ply carbon fiber, at worst it’s a printed and stuck on. Other then that it’s quite stiff and feels well built. On one side all the inputs and outputs are laser engraved and easily read.

At the front you have one USB-A port for output only, up to 18W, then you have a USB-C port that can be used for In or out at 18W each. Next to it you have the single button on the powerbank with 3 blue LED underneath for power indication.

Oh and it’s water rated at IPX5 which is rare for a powerbank. It means it can sustain a low pressure jet of water or splashes, so it’s perfect for adventuring. Even though it’s not officially rated for it, I did submerge it briefly and it survived. 


Size and Weight

I measured it as 122mm long, 59mm wide, and 10.5mm thick. This is nice and thin and slides behind most modern smartphones in a pocket while charging which is convenient when traveling. At 151.2 Grams it’s pretty light too thanks to that use of carbon fiber.

When I compare it to my Aukey 10,000mAh powerbank the Aukey is wider, longer, and 43g heavier. The 10,000mAh Anker powerbank I have is shorter but significantly thicker, I suspect it’s using cylindrical cells (21700?) and is 41 grams heavier. 



As mentioned the NB10000 has one USB-A port for output only, up to 18W, then you have a USB-C port that can be used for In or out at 18W each.

I did my charging tests with my 65W Aukey GaN chargers that I previously reviewed on this channel and had no issues. Total charge time was 3:13:00. Peak charge I saw was 8.9V at 2.0A, or right at 18W. My CT-2 Meter recorded a total of 43.44Wh went into the battery. 


Official Specs are as follows

Input – USB-C: 5V @ 2.4A or 9V @ 2A

Output – USB-C: 5V @ 3A or 9V @ 2A or 12V @ 1.5A

  USB-A: 5V @ 3A or 9V @ 2A or 12V @ 1.5A

I ran 3 discharge tests, 5V at 3A, 9V at 2A, and 12V at 1.5A each performed as expected with power being pretty stable. 


At 5V at 3A, I measured total energy at 31.29Wh, and average voltage at 5.18V and a total discharge time of 2:01:05.


At 9V at 2A, I measured total energy at 29.16Wh, and average voltage at 9.14V and a total discharge time of 1:35:58.


At 12V at 1.5A, I measured total energy at 29.71Wh, and average voltage at 12.02V and a total discharge time of 1:38:58, with a bit of voltage step down the last 20 minutes.


The NB10000 also offers Passthrough Charging meaning you can connect it to your charger, via USB-C and then charge your phone or other device (Flashlight) via the USB-A port, and both will charge at once. It’s not the full 18W speed but for me both my phone and the powerbank were full in the morning, making this great for backpacking or travel.


I charged my good old Note 8 from 15% to 100% in 1:51:00 via USB-C with 2/3 lights lit on the powerbank. I charged my phone again from 50% to 100% and the powerbank was still showing ? full. 


It’s nice that the powerbank has a low power mode that you can activate by pressing and holding the single button until a white LED comes on underneath. This is perfect for charging an increasing number of low power devices like wireless headphones, smart watches and other wearables. 



  • Carbon Fiber! I am a sucker for carbon, real or fake it doesn’t matter.
  • Really small and compact
  • Supports 18W in or out, and charging via USB-C PD.
  • Low power mode



  • The indicator LEDs are too close together to easily read.
  • Passthrough charging works but is fairly slow.  
  • On the pricey side these days, but it is a premium build quality.



The NB10000 is a small, well built powerbank with a great size to performance ratio. It has the features I am looking for in a powerbank in 2020, like PD support, 9 and 12V, and a low power mode. It doesn’t hurt it’s made of carbon fiber too since I am a sucker for it. That said you pay for these more premium features and this isn’t a cheap powerbank.


That said it’s my new travel charger since it’s so easy to put in a pocket and charge on the go. It also fits nicely in my camera bag which is also a plus. The traditional powerbank brands better watch out because Nitecore has them in their sights.

Nitecore MH12GTS (1800 Lumen, 18650, 1” Tactical)

The Nitecore MH12GTS is the upgraded version of the popular tactical MH12GT. It features and upgraded LED, 1800 lumen max output, microUSB charging, and an included 18650 battery. Thanks to the for sending this to me to take a look at.

Full Image Gallery:

The YouTube version of this Review:

This light comes in a Nitecore standard black and yellow retail box. On the outside there is quite a bit of info on the light. On the inside the light sits in a plastic tray with all the accessories and manual underneath. Included accessories are the light itself, lanyard, microUSB cable, pocket clip, tactical ring, NL1835HP 3500mAh button top battery extra orings and a velcro pouch.

The Nitecore MH12GTS is made of machined aluminum and his hard anodized a mostly glossy black. Starting at the tail cap, it has large lanyard holes on either sides, and does tail stand. The sides are cut down to allow for a finger or thumb to access the off center silicon textured button. It’s a pretty stiff button for a full click and mechanical. Opposite the button is a flat facing port cover for the USB charging port. The cover stays in place pretty well. The USB port underneath is waterproof and I will test that later in the review. Spring inside the tail cap is stiff and dual construction

This uses a dual tube style construction, from what I can tell the inner tube is not removable. Threads are a steep ACME cut and unanodized at top. The tactical ring on this light is threaded. I like this and means that it won’t’ freely spin like happens on many other light designs with a similar ring.There is an oring above the tactical ring.The body tube has smooth knurling but has horizontal lines milled in to break this up and then for the flats where the labels are they are milled a decent amount lower. This provides a bit more grip. The body tube looks like it’s removable but I can’t get it to budge. Further up the light has an anti rotation ring that’s small.

The head of the light has minimal heat syncing and heat hasn’t been a major issue here because the light does step down. The button is metal and has a clear Status indicator ring around it with a blue LED underneath. The head is pretty smooth. The bezel is smooth and the glass is anti reflective coated. The reflector is fairly deep for a 1 inch light and the LED is nicely centered.

The pocket clip on this light slots in right below the tail clip on the body tube. My first clip didn’t fit very close to the body of the light. I contacted Nitecore store and they promptly sent me a new one which was a much better and closer fit. I would prefer a clip that allows for deeper carry personally but this seems to not be what is done on most lights similar to this one.

I measured length at 144mm. Maximum diameter is 35mm at the tactical ring, max diameter of the body is 26mm. Weight with the battery and pocket clip is 153.1 grams.

Size comparison with the Olight M2R Warrior is that they are very similar in diameter. The light is shorter at about 15mm. The nitecore is slightly lighter.

This light uses a Cree XHP35 HD LED in cool white. It’s capable of producing upto 1800 lumens in turbo mode. It throws pretty well due to that deep reflector. Overall the beam has a hot center and about 4 distinct rings. It’s not a very smooth transition to spill. The brightest hot spot has a bit of discoloration in the very center. This is easily noticed straight on against a surface that’s all the same texture and color such as drywall or concrete. It’s noticeable at distance as well.

Turbo 1800 Lumens
High 900 LUmens
Mid 240 Lumens
Low 70 Lumens
Ultra Low 1 Lumen
Strobe/SOS/Beacon 1800 Lumens

Power and Runtime
This light is capable of running on 18650’s, CR123a, and RCR123A. 2× 18350’s is not recommended due to too high of voltage. To access Turbo you need cells capable of 8A or more. Total runtime with the included 3500mAh battery was 142 minutes. Turbo run time starts decreasing almost immediately. It has a run time of about 3 minutes. When the light steps down you are getting about 45% relative output for about 20 minutes. Between 20 minutes and 142 minutes the light is pretty stable between 45% and 35% relative output for 120 minutes. Heat is pretty well managed.

Turbo Runtime

Full Runtime

One thing worth noting is that the manual says “When using an IMR 18650 battery and the power level is low please stop using the product when the power level is low to prevent damage to the battery. An IMR battery is what the light ships with. This suggests that the light doesn’t have low voltage protection for this type of battery built in, so using protected cells would be a good idea. Lucky the one that ships with the light is protected.

The tail switch on this light functions as only an on and off. It takes a decent amount of force to press, I think this is good for a tactical light.

For normal operation this light has 5 modes, UltraLow, Low, Mid, High, and Turbo. When the light is on the mode button cycles through them. Memory mode is strong on this light and works everywhere except strobe.

Momentary access to turbo is possible if the light is on by holding the Mode button for 1 second, if you let off it returns to what mode you were in previously.

Strobe on this light isn’t at just one rate. It’s pretty fast and then alternates between fast and really fast. I like it, I just wish strobe wasn’t so easy to access with just a double click of the mode button. When in st4robe you can also get to Beacon or SOS by long pressing on the mode button. To exit a special mode just short press on the mode button to return where you were previously.

Direct access to moonlight mode can be accessed with the light is off by pressing and holding the mode button, while actuating the tail button, so it’s a 2 hand operation.

This light has recharging via microUSB on the tail cap of the light. There is a rubber flap that protects the port from dust and moisture. The port is also conformally coated, so it’s protected from moisture even if the flap is open. To test this I dunked it in water and then blew some air in the port with my mouth and proceeded to charge it without issue. There is also a small blue LED built into the tail cap to show charging status. Blinking blue means it’s charging, solid blue means it’s full.

The disappointing thing about charging via USB on this light is the speed. I saw charging speeds at it highest at only 0.64A. So for the included 3500mAh battery that means a full charge took me 10 hours, 9 minutes. This is really slow in 2018 for a premium light. I would expect a minimum of 1A these days, if not closer to 2A to cut down on the charging time substantially.


  • Comes with a nice high capacity Nitecore battery
  • Waterproofing even with the USB protective cap off
  • Quick access to ultralow 1 lumen mode


  • Slow onboard Recharging .64A means using onboard recharging takes forever.
  • Beam throws well but has a slightly more dim area in the direct center.
  • Not a big fan of double click to strobe, I would prefer double click of the mode button to go to turbo and triple click for strobe.

The Nitecore MH12GTS is a pretty nice tactical style light with a good amount of throw for its compact size. The UI takes a little while to get used to but if this was a light you used often I think most would like it. I like how it’s able to use a pretty wide variety of power, including primary and flat top unprotected 18650’s. I like that Nitecore has put a lot of effort into making the USB port waterproof. I can get past the beam irregularities in normal everyday use, but the slow charging time is hard to live with on a premium light. Overall it’s a nice showing here from Nitecore and one that will be especially useful for a nice throw in a small diameter light.

Nitecore TM06s Review

At 4000 lumens on turbo this is quite an impressive light. I did a table top review and then took it out to a park at night to show the beam and distance. It was impressive and the Bugs loved it.
