[Review] Angryfox Playfox K1 and K1s

Review copies was sent in by Angryfox to me here in the Philippines, whom I thank for the confidence afforded to me.

Angryfox sure knows how to be playful as well! The Playfox K1 and K1s is a very small, compact keychain fun light by Angryfox. It is a keychain light with a set of three different colored diffusers which makes it unique and somewhat cool.

It comes wrapped in bubble wrap, secured well in the transit box in a matte white retail packaging with gold foil stamped accents on the sides, and at the back are the colors available.

Some information can be read on the front of the packaging just below the two plastic windows which lets us see a preview of the light inside the box along with the three different colored diffusers.

1x Playfox K1
1x Manual (English and Chinese)
3x Silicone Diffusers (red,green,blue)

Quick Features and Specs:
-Digitally regulated output that maintains constant brightness
-Designed with mechanical anti-reverse connection
-Designed with PMMA lens
-Has 3 colored silicone diffusers
-Has over-heat protection that avoids high temperature on the surface
-Utilizes a CREE XPG2 R5 LED with a lifespan of 50000 hours
-Runtime of 110 hours
-Has a warning light function
-Weighs only 10 grams (w/o battery) , the sus version is 21 grams
-Max output of 100 lumens

Twist the tail cap tight to turn ON the light. Twist counter clockwise to turn OFF, then clockwise again to change modes.

Starts with MED-HIGH-LOW, then again MED-HIGH-LOW, then warning light.

Form Factor:
This is a very compact, simple, small keychain light. It is very smooth, sleek and flawless design from head to barrel.

The bezel has 3 groups of groves, possibly cooling fins, all around it that helps with heat dissipation.

The lens are clear, with a polished smooth reflector.
On the center is the LED perfectly situated.


The barrel is sleek and smooth, with a grove near the head to secure the silicone diffuser. The model can be clearly read on one side.

and the brand written on the other side

The threads are mildly lubricated as well as the o-ring.

The diffusers are three (blue,green and red),

which have a small circle shaped hole in the apex of the diffuser to somewhat let light through for illuminating a greater area.

The tail end is one with the barrel on this light, and a little conical, slightly pointed in shape, attached to it is the small keyring.

Side by side:

To sum up, I believe that the most important part of any review is if given the chance to purchase the same light for my own EDC, would I still purchase it?
For this light, it is a definite YES. Specially if you are looking for a small, compact and most of all fun keychain flashlight with complete functions.
Scrutinizing the light over throughout the review, I am hard pressed to find any flaws at this price point. If I were to nit-pick, it would be the mode functions, it is somewhat weird for me that it starts of in MED, then going to all the modes again MED-HIGH-LOW to go to the warning light, they should have just made it by twisting it fast two times to be able to go to the warning light function. But overall, on this price point, and the light quality and lumen output, I would say that this is clearly a good value for money, specially if you are into twisties! Awesome fun light by Angryfox!

As with all gears, two is one and one is none.

Light on brothers!

I hv the K1 and I love it. Its one of the smallest multi mode single AAA flashlight. Since it is so small, i wear it on a chain. So its always on me.

Better to hv it and not need it than to need it and not hv it.

I really wanted to like this light, as it’s got the potential to be a backpacker’s (globe-trotter type) pocket light:

1. Low “Low” (2 lm) – not moonlight or firefly, but still good when sleeping in dorms etc.
2. Very compact & lightweight, but also feels sturdy.
3. The smooth finish (= no knurling) means little chance of accidental activation.
4. “Mid” lumens (20 lm)+runtime (~5.5h) strike a great balance for a backup hiking light (forced night on the trail etc.).
5. The warning/beacon (flashing) mode is better than many, with the light on LOW and pulsing HIGH every 1s. Much better than the usual strobe, especially for emergency signaling.
6. Diffusers attach to the flashlight body (though a white/neutral diffuser is missing and would be a welcome addition).

However, the UI is simply the worst I’ve seen.
1. Mode order M-H-L, kills night vision, wakes up everyone around before you get to that Low, wastes battery juice.
2. Next-mode memory. Enough said.
3. Memory lasts a few minutes. Not sure how many but certainly more than 5.
4. …which also means the beacon is kinda mandatory mode (not hidden).

I also think an extra O-ring in the package is expected those days.

AngryFox! remove that next-mode memory, and use a much more sensible LMH for a light that’s likely to hang on a keychain, and that would bump up the usabilty of this potential gem.

Next-mode memory.

I wrote to Angryfox and they say the light has normal memory, not next mode memory.

Can anyone verify Bamba’s real world experience. Is your K1 a light with normal last mode memory, or does it really advance to next mode after being off?

both are bad imo.. since I prefer to know what mode my light will turn on at, every time.

With memory, the only thing I can be sure of, is that I wont remember what mode I used last and will have to cycle all the modes to find the lowest one.

Is the LED placed on the driver PCB or does it have a separate MCPCB with a reasonable thermal path?
