Inside an EDC V3 flashlight (with schematic)

- I'll just assume that this unit is a clone of one of the many similar looking products. It's hard to tell which came first in a sea of lookalike products. I'm sure the true flashlight connoisseurs will know.
In the UK we call these torches, which is kinda bizarre, since it's literally a progression from the original blazing stick that was used for light in the long distant past. According to Wikipedia the word torch comes from the French word torche, representing the fuel carrying wick wrapped around the end of the stick. So basically speaking this torch is an electronic blazing stick that fits on your keyring.
This link finds them on AliExpress. Target price around 10 pounds.

The lithium cell claims to be 500mAh, which is viable for its size, and it is charged at a current of around 350mA. The USB C charging port does not have the load identification resistors, so some smart chargers may not detect its presence and will not charge it. A plain dumb charger will charge it.
The front LEDs have five modes. Brief high power output and four latched intensities, with current draw at 4.2V as follows:-
Momentary high power = 2000mA
High = 660mA
Medium = 140mA
Low = 67mA
Night light = 13mA
The small side LEDs have two chips each and are run at 100mA.
If you enjoy these videos you can help support the channel with a dollar for coffee, cookies and random gadgets for disassembly at:- www.bigclive.com/coffee.htm
This also keeps the channel independent of UA-cam's algorithm quirks, allowing it to be a bit more dangerous and naughty.

There is a community of flashlight modders that reprogram the chips in flashlights. Any of those people here?
I bought this exact flashlight recently! It's got everything I was looking for in an EDC flashlight, especially the low-power red light led for providing tiny amount of light in my tent without screwing up my night vision.
In retrospect I’m surprised there was never a 1980’s TV show called “Police Mode”.
Suggestion for those buying one of these: Buy the clear one, not the tinted one. It's glow in the dark!
Imagine getting into a Chinese elevator. Minimal buttons to keep costs down, so you have to know the weird pattern of pushes that specific control panel model was created to accept. Imagine a car, or an airplane cockpit.
I waited for the “One moment please” and was not disappointed. Next time I expect a “Watch your eyes. I’m turning the light back on”.
Things I have never in all my years ever wanted a flashlight to do: strobe on and off rapidly
I don't get why these things don't have a power switch and then a mode/brightness button, it would make them so much easier to use
"Maybe I shouldn't be stabbing it in there" 😂😂😂
"It has so many modes and only 2 buttons" Yeah Clive wait until you discover the clicky wonderland behind the lenses and reflectors called Andúril or Andúril 2. 😀
I gotta say Big Clive. My pop was an engineer in Chicago and maybe it's genetic but since I was like 7 years old, I just loved dragging stuff home from the alley to take it apart. Were you like that?
takes my back to my ‘engineering’ youth. The exquisite joy, fear, guilt and wonder when realisation hits that I have effectively broken the ‘thing’ and needed to hide the electronic corpse.
I can honestly say not knowing much about this type of stuff in my 25 years if work in heavy civil. I really appreciate your show you are very clear , and break things down so people with little knowledge can actually learn from you. Respect Sir
Would very much like to see you do a dedicated video on how to reverse engineer a circuit board, from analysing the board to producing a schematic diagram.
Hi Clive, thanks for the interesting video! I recently bought a similar V10 version that has a 1000ma battery and even more LEDs and alarm ‼️ sound. It has a clear plastic shell that glows a little in the dark. I guess the internal layout will be much the same as the V3. I'm quite impressed with it’s design and quality. Cheers…
I've mentioned you in the description of my review of this light, and added a link there. Thank you for the in-depth view of this light, and how to take it apart. I've been tempted to see what's inside, but I don't have any clue on electronics.
The Torque Test Channel had a pretty good economy luminosity test rig. It was a combination of a hollow stryroform dome and a light sensor. I think they have a video explaining what went into it.
Thank you for sharing this informative video, Clive! I own the same flashlight and it was fascinating to get a closer look at the inner workings of it. Your explanations were clear and concise, which helped me gain a better understanding of how it operates. I would love to see you do a video on a Nitcore light next. It would be really interesting to compare the qualities of these flashlights. Keep up the great work!
Oooh, I saw these while looking at the ones you covered recently. Glad to see you pulling one apart.
As always Clive shines light on the subject.
