Manker MC01 Flashlight Review

Manker MC01 Flashlight Review

The Manker MC01 is an interesting little flashlight with a built in 18650, simple user interface, and USB-C charging! Read on for more!

Official Specs and Features

Here’s a link to the Manker MC01 flashlight product page.


I think there’s just one body available of the MC01, but it’s available with either neutral white emitter (seen here) or cool white. More on this later, but note that the neutral white is much more of a warm white!

Short Review

I didn’t initially know that the MC01 has a built-in battery. That’s a downside but I’d realy say that’s one of the few downsides. Despite that built-in cell, I actually really like this light! I could handle a lower low, but I can live with every other concession it makes. And the price is low!

Build Quality and Disassembly

Manker MC01 flashlight

The Manker MC01 is a very nicely built, simple flashlight. Despite looking quite traditional, it’s different in that the cell is built-in and not (really) user-serviceable. That makes it a good and safe option for those users who might otherwise not be comfortable with lithium-ion cells, though. 

As the light is sealed, there’s no disassembly to show. If you were inclined to tear the light down, I think you’d have to go in from the front by removing the TIR!

Size and Comps

4.03″ / 102.3mm (length) x 0.98″ / 25mm (head of diameter)
3.31oz / 93.8gram (built-in battery)

If the flashlight will headstand, I’ll show it here (usually the third photo).  If the flashlight will tailstand, I’ll also show that (usually in the fourth photo).

Here’s the test light with the venerable Convoy S2+.  Mine’s a custom “baked” edition Nichia 219b triple.  A very nice 18650 light.

Also above is the light beside my custom engraved TorchLAB BOSS 35, an 18350 light.  I reviewed the aluminum version of that light in both 35 and 70 formats.

Just so that I’m sure to say it somewhere – the Manker MC01 is a great sized EDC flashlight. It’s in the realm of some Zebralight 18650 lights, and that’s saying something!

Retention and Carry

A pocket clip ships attached to the MC01. It’s a friction fit clip though, so can be removed.

The clip is what I call a “standard Lumintop” clip.

The included lanyard can only attach to the pocket clip. That’s ok, but not just the most secure spot, as the pocket clip is a friction fit clip.Manker MC01 flashlight lanyard

Power and Runtime

The Manker MC01 flashlight is powered by a built-in lithium-ion battery. This cell is not replaceable for the average user. Because of all that, I don’t have any photos of the cell (or even inside the light, for that matter.)

I would imagine the specification of output claim is made for the cool white version, and this “neutral white” (more of a warm white) is much lower. This is to be expected. That it’s this much lower only supports that the output is warmer than “neutral.”

The charging area has an indicating LED, but that doesn’t seem to indicate the charge state when the light is on


Along with the built-in 18650 cell comes built-in charging. On the Manker MC01, this is by way of a USB-C charging port in the tail. In fact, the charging port cover is quite like the e-switch – the differ in profile (with the e-switch having a very slight dome – higher than the charge port cover). 

I found the charging port cover to be difficult, and always required a tool to get under the flap.

An appropriate cable is included – USB to USB-C.

C to C charging works fine, too. It is ever so slightly quicker.

While charging, a red indicating LED under the e-switch cover is lit. When charging is complete, a green LED is illuminated.

Modes and Currents

Mode Mode Claimed Output (lm) Claimed Runtime Measured Lumens
Turbo 1030 2h30m 496
High 600 2h40m 305
Middle 300 5h 167
Low 60 29h 31

Pulse Width Modulation

Every mode uses PWM. It’s fast PWM though, so nothing to really worry about.

For reference, here’s a baseline shot, with all the room lights off and almost nothing hitting the sensor.  Also, here’s the light with the worst PWM I could find.  I’m adding multiple timescales, so it’ll be easier to compare to the test light.  Unfortunately, the PWM on this light is so bad that it doesn’t even work with my normal scale, with is 50 microseconds (50us).  10ms5ms2ms1ms0.5ms0.2ms.  In a display faster than 0.2ms or so, the on/off cycle is more than one screen, so it’d just (very incorrectly) look like a flat line.  I wrote more about this Ultrafire WF-602C flashlight and explained a little about PWM too.

User Interface and Operation

As stated above, on the tail is an e-switch. This switch shares space on the tailcap with the charging port. The two are very similar, except that the e-switch has a slight dome.

It’s possible to differentiate the two by feel, despite their similarity.

Here’s a UI table!

State Action Result
Off Hold Low
Off Click On (Mode memory of Low/Middle/High)
Any Double Click Turbo
On Hold Mode advance (LMHML)^
On Click Off
Turbo Double Click General Modes (Low/Middle/High)
Any Triple Click Special Modes (Strobe/Beacon/SOS)
Special Modes Triple Click General Modes (Low/Middle/High)

^ When holding the switch to advance modes, the output ascends through three modes, then descends through the modes. The MC01 will continue this cycle up and down.

LED and Beam

In the Manker MC01 is a Samsung LH351d emitter. My review copy is the “neutral white” version (cool white is also available). This emitter is coupled with a dimpled TIR optic and gives a fairly diffuse beam pattern.

LED Color Report (CRI and CCT)

As you can see from the photos above, this is a warm emitter! I read the output at a CCT of around 3900K, and that’s steady for all four modes.  CRI is also high, at around 90. The CCT claim is 4000K, so I’d say Manker did it about right with this one.


These beamshots are always with the following settings:  f8, ISO100, 0.3s shutter, and manual 5000K exposure.

Tint vs BLF-348 ( 219b version) (affiliate link)

I keep the test flashlight on the left, and the BLF-348 reference flashlight on the right.

I compare everything to the 219b BLF-348 because it’s inexpensive and has the best tint!


What I like

  • Nice CCT (neutral or warm, the “4000K” is nice)
  • High CRI
  • Simple user interface
  • Great size for edc

What I don’t like

  • Built-in batter is not user-serviceable
  • Low of “60” lumens is much too high
  • Charge port cover is fiddly
