Thrunite Archer Mini Flashlight Review
Thrunite has introduced the Archer Mini, a flashlight featuring a built-in 10400 cell, two modes, and USB-C charging. Read on!
Official Specs and Features
There’s just one version.
The going price of the Thrunite Archer Mini flashlight is $25.95. That seems to be the MSRP, so maybe street price will be just a bit lower.
I very much appreciate the idea of this light. A small, simple, two-mode light in an AAA-size format. USB-C charging is great (and works C to C!). I would rather that the cell be removable, and also prefer that the light could accept AAA (1.5V) cells. The beam profile is great, but the tint is just a bit green. Still, at around 5500K, it’s not a bad emitter.

^ Measurement disclaimer: I am an amateur flashlight reviewer. I don’t have $10,000 or even $1,000 worth of testing equipment. I test output and such in PVC tubes!! Please consider claims within 10% of what I measure to be perfectly reasonable (accurate, even).

Package and Manual
Build Quality and Disassembly
83mm x 16.7mm
If the flashlight will headstand, I’ll show it here (usually the third photo). If the flashlight will tailstand, I’ll show that here, too (usually 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.
And here’s 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.
Retention and Carry
There’s a two-way pocket clip attached on the tail end. The clip can’t go on the head end, but again, it’s a two-way clip.
While the clip can be removed, the light does look a bit naked without it.
Nothing else is included for carry of the Thrunite Archer Mini flashlight.
Power and Runtime
A single cell powers the Thrunite Archer Mini flashlight. It’s not [really] removable, and appears to be a single 320mAh 10400 cell.
The light has just two modes, and here are runtime graphs for both.
You can see after the very flat regulated output stops, the light begins blinking to indicate the cell voltage is low. Eventually the light does shut off.
Thrunite put USB-C charging on the Archer Mini. To reveal the charging port, one just unscrews the head.
The head is “captured” though – it doesn’t unscrew all the way off. It unscrews to the point you can see below. You can also see the charging indicator. This indicator blinks blue while charging is happening, and switches to solid blue when charging is complete.
Both types of charging (A to C and C to C) work fine.
Modes and Currents
|Mode||Mode Claimed Output (lm)||Claimed Runtime||Measured Lumens||Tailcap Amps|
Pulse Width Modulation
Low has PWM that’s surprisingly slow. It’s visible if you typically find PWM visible, but surprisingly doesn’t seem all that bothersome in this light.
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). 10ms. 5ms. 2ms. 1ms. 0.5ms. 0.2ms. 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
A single switch is used on the Thrunite Archer Mini flashlight. It’s a tail switch and has a rounded cover.
Despite appearances of being a mechanical switch, I’m fairly sure this is an e-switch of some sort. I reason this because when you hold the switch down, the light will come on after about a full second. A mechanical switch would not do this.
The dome of the switch and also the rounded shoulders you can see above make
I will add that I had a number of accidental activations in my pocket during use. You’ll probably want to use the lockout feature.
Here’s a UI table!
|Any (Unlocked)||Double Click||High|
|Lockout||Click||Single Low blink to indicate lockout|
|Any (Unlocked)||Click 3x||Strobe|
LED and Beam
Thrunite uses a Luminus SST-20 emitter and a TIR optic.
The bezel is smooth so no light escapes when headstanding.
LED Color Report (CRI and CCT)
Thrunite logs this as a cool white emitter. I measure it at around 5500K, which is sort of “barely” into the CW realm. It’s quite positive in the dUV though, which readily explains the green nature of the output. CRI is fairly low, too.
These beamshots are always with the following settings: f8, ISO100, 0.3s shutter, and manual 5000K exposure.
Tint vs BLF-348 (KillzoneFlashlights.com 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 KillzoneFlashlights.com 219b BLF-348 because it’s inexpensive and has the best tint!
What I like
- Simple user interface
- Just two modes
- USB-C charging (with C to C working, too)
- Beam profile provided by this TIR
- Rounded switch and tail end of the light are comfortable to press.
What I don’t like
- Green tint in the beam
- Not a mechanical clicky (potential for parasitic drain)
- The internal 10400 cell is not replaceable
- 10400 cell is a weird size anyway, even if it’s not replaceable
