Only one version.

At GearBest it’s currently $20, which is probably around the going price.

Short Review

I can say honestly that I like this way more than I expected to.  The output is positively flat until the light shuts off, and the user interface is good with no silly strobe modes.  It’s not all that bright, and the emitter is dated, though.

All my Xiaomi reviews!

^ Measurement disclaimer: Testing flashlights is my hobby. I use hobbyist-level equipment for testing, including some I made myself. Try not to get buried in the details of manufacturer specifications versus measurements recorded here; A certain amount of difference (say, 10 or 15%) is perfectly reasonable.

What’s Included

• Xiaomi Mi flashlight
• Charge cable
• Lanyard
• Manual (completely in Chinese)

Package and Manual

This light ships in a clear plastic tube.  There’s not much useful information for the end-user on this package.

The manual is completely in Chinese, rendering it completely useless for me.

Build Quality and Disassembly

The light has a surprising feel, much like that o the XTAR Over 4 Slim I recently reviewed.  It’s soft (coated?) plastic, and quite grippy.  The head has a satin feel.

The build quality is probably approximately that of a $20 light.  The body feels good quality, but the emitter is not even specified, and looks to me to be a very dated one.

To be perfectly honest I’m not sure yet how to disassemble this light.  There are no visible connections, and the head twists freely in both directions.  The TIR is stationary.  The tailcap is probably the means of ingress.

Size

Officially 12.02cm long x 2.55cm wide.

This is by no means the smallest light, but I can’t think of a smaller light that has onboard charging and may be used as a powerbank.  So its feature set makes it a reasonable size.

Retention

Xiaomi provides a silicone lanyard, which connects to a small hole in the tail end of the light.  The silicone lanyard is fitting to the overall feel of the light.

There’s no pocket clip.  In fact, this light doesn’t lend itself to that kind of carry at all: it’s a completely straight featureless tube light.  There’s nowhere for a clip to attach.

Power

This light (which seems to lack a proper name) is powered by a non-replaceable cell.  Very likely a single 18650, of course.  Below is a runtime on the highest mode.

That output is quite unusual – almost perfectly flat until the light shuts itself off.  There’s no stepdown, no nothing else.  Just solid runtime until off.  The rated runtime on this mode is 216 minutes, but the light falls a little short of that.  It looks like the output might vary with room temperature in fact, but only very slightly (probably the difference in emitter efficiency at 22 vs 24 degrees, as specific as that seems.)

Charging

This light also boasts onboard charging, which is done by micro-USB.

Note that those two plugs aren’t sealed in any way at all.  This is a huge downfall!  But as a bag light, possibly not a deal-breaker.

Here’s the provided power cable plugged in the light.

Below is a charge test, starting at the end of the runtime above.  The initial rate is around 0.8A but stabilizes at around 0.65A.  I am not sure why there are dropouts as seen up to 150 minutes, but that seems to stop, and charging continues as it should.  The cell looks to be around 2600mAh, which again is reasonable for an 18650.

The final power option for this light is the USB-out powerbank feature.

User Interface and Operation

There are two inputs on this light.  The first and main is the twisty head.  Twist one way for on and twist the other for off.  The twist is very low friction, but still has a clicky detent where the modes change.  The light will click through 3x turns before it comes on.  It’s also an e-twisty.  By that I mean it will twist continually in either direction, and it’s essentially firmware (not hardware) that advances the modes.

The second option is the indicating e-switch on the tail.  This switch is involved in turning on and off various features of the light.  For example, if the light is on, pushing this switch will turn it off.  But both micro-USB charging and USB out start automatically when connected.

The tail switch may also be triple clicked for SOS.  During SOS the twisty does nothing, and the switch must be actuated to turn off SOS.  Clicking this switch while off will give an indication of the battery level, too.  Green indicates charged (and so on – I can’t read the manual, but red of course indicates that it’s time to charge the cell.)

LED and Beam

The emitter isn’t mentioned in the product listing.  And based on what I know about emitters, this one is quite dated.  That’s actually quite disappointing and unfortunate.  The light otherwise has a fairly good niche use, and a good emitter would round that out nicely.

The emitter is behind a TIR, and the beam profile is quite a spot with little spill.  There’s a fair bit of green in the beam, too.  At a distance, it’s not that bad.

Beamshots

These beamshots always have the following settings:  f8, ISO100, 0.3s shutter, and manual 5000K exposure. These photos are taken at floor level, and the beam hits the ceiling around 9 feet away.

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

Random Comparisons and Competitive Options

To be honest, there are a number of cheap powerbank lights on Amazon(et al) that compete with this light, but this might be one of the better-built ones.  I happen to typically like Xiaomi items (see my keyboard review here).  Is this one worth $20 over the others?  I haven’t had those but they do look cheap.  This one overall feels decent quality but would benefit from an emitter swap.

Conclusion

What I like

• Unusual body is nice to hold.
• Twisty is different and easy to use (and I don’t normally like twisties).

What I don’t like

• Emitter is dated
• Built-in cell is not swappable
• Built-in cell has low(ish) capacity
• Too big for comfortable pocket carry
• No waterproofing (!!!)
