eBay 98kW LED flashlight (slightly exaggerated) with schematic
Вставка
- Опубліковано 1 тра 2024
- Another of the many products on eBay where the sellers try to outdo each other with very ambitious ratings. Far too ambitious in this instance.
The construction of the light is interesting because it has been optimised for fast manufacture.
The circuitry is ultra minimalist, including the USB charging circuitry that doesn't inspire a lot of confidence. Don't leave one of these on continuous charge.
Other than that, it does work, the beam focus feature works well and it doesn't have too many useless modes.
The cell capacity tests at a very ungenerous 160mAh and the charge circuit does keep trickle charging the cell after the LED has stopped flashing, and when I monitored it for a while it peaked at a slightly uncomfortable 4.27V then suddenly settled back down to 4.21V, making me wonder if it had energised the load briefly when I wasn't there as part of its charge control.

I'm not buying any flashlight less than 1MW.
Good news. If you search carefully, you will find plenty of 2MW and 5MW lasers ...
Ok. What? Video is uploaded 56 minute ago and your comment is 8 days old...??? Awesome bug. 👍

@@TheLordNemesis From UA-cam? I thought Patreon has it's on video platform. OK.
Thnx for clearing my doubt.
Brave to stick your hand straight into a 98kW beam.
Hats off to Clive for risking life and limb to make us content...
😆
Balls of steel, I tell you!!!
As brave as honking those Aliexpress 600 db horns.

98 K W Beam, effing amazing, from such a tiny power source too? Those clever people, sure you couldn't be up to them foreigners?
I'm impressed that a 160mAh battery was able to power a 98kW beam for more than 20ms
That's a 160 Amp battery.
@@solarsynapsemaybe it’s a 160mah battery at 96kV
@@Himechinachae I don't think so. Some of the wires are too close together, and arcing would occur, since the dielctric strength of air is about 3 kV/mm.

"It's out. [snort]" It's the snort that really sells it.
Could you not love Clive enough 😂 ...... the "snort" expecting the "shaft" to expell with some resistance and yet with unimaginable ease. Cough, cough ..... it falls apart. Seriously though, HA, isn't it enough already being sold mislabelled items on Internet.
You could truly hear Clive's amusement. 😂
I also snorted a moment before the did and when he did I died XD
The fact that it required force to disassemble and didn't just fall apart actually puts it in the top tier of ebay torches
Assuming the LED drops 3V, then the battery must supply 32,667A. With a capacity of 160mAh, the light produces 98kW for 4.8μs. Very impressive, I think we can all agree.
Must be the strobing mode :-p
If you really could get 98kW from an instrument that size, the National Ignition Facility people would like to hear from you! They could replace all those expensive lasers and initiate fusion with a bunch of pen lights.
Maybe it is just extremely pulse modulated the NIF lasers are something like 500 trillion watts so if that thing is pulsed for a nanosecond or whatever perhaps it is outputting 98kW
@@glenecollins Then the shutter mechanism would be worth repurposing!
Build an artificial sun with a million of this flashlight combined and voila, UNLIMITED POWER!
@@glenecollins I seem to remember from visiting Harwell that some of the extremely powerful lasers which they have there output in one burst the same amount of energy which you'd get from eating a Mars bar. Perhaps a similar case? Vulcan - that's the chap. Each burst lasts less than a pico-second.
@@sihamhamda47 Point it at a solar cell and you would get about 20kW back. You can certainly power more than one of these lamps on that, so all you need to do is cascade lamps and solar cells until you have satisfied the entire energy needs of humanity!
Technical team: It's 98mW
Marketing team: Let's do a clever "typo"
It could be from one of those countries that swaps the commas and the periods for decimal separator. 98,000 watt might be 98.000 watt. Still, marketing knew what they were doing.
@@hotlavatube 98W would also be a laughable lie
@@TheGreatAtario Well, if you remove the resistor between the LED and the battery you’d probably be able to get 98 watt… for maybe a second before the LED burns out, but hey, mission accomplished!
@@hotlavatube Which resistor?
@@M4RC90 Ah right... I double checked the video and Clive did say they didn't use any resistors to limit the current. Well then, we'll just have to swap the battery with something with a little more oomph then!

My eyes still haven’t recovered from the mind blowing power of that torch
My Tablet screen melted! ... Big Clive owes me £110! 🤣
Well, I purchased a small flash light that advertised itself at being super bright, where my eyes have likely been damaged from using it. It was only 5 Watts although used a UV diode that produces UV light that can cure UV epoxy. Really burned my eyes and had giving me headaches and had me seeing spots after using. Gotta be careful of cheap Chinese cr*p!
Was several months when accidentally I noticed it could cure UV Resin, and thus was the cause of my eyesore. Now I'm paranoid of Chinese led products.
I must get one to point at my solar panels to charge my Tesla on a cloudy day.
"98 Kilowatts of disappointment". Me too. I wanted to see that irritating burnt squiggle made with the Temu gismo vaporised.
The 9 million mAh power bank would be the perfect complement for this 98 kW LED flashlight. They should start selling them as a combo.

Sounds like a euphemism.
Or a refrigeration engineers, pipe cutter
I've used a 1/16 inch or 1.6mm drill bit held in a small pin vise, and I drill a small hole in the plastic. Then I screw a M3 or M2.5 by 6mm sheet metal screw into the hole I drilled. Now I have a 'handle' to grab onto with a pliers or dikes and give the plastic a strong pull. This allows getting inside to repair. 👍
Ebay watts are on a slightly different scale to regular watts.
Computer storage on AliExpress has a different scale too. I’ve seen ads posted for SSDs and flash drives ( SD & micro SD cards ) that had capacities in the petabytes (1 petabyte is 1024 terabytes, or 1000 depending on if it makes the company more money) for less than what the similar sized storage in terabytes would cost. Wish they were real as I would buy a bunch and have all of my storage space taken care of until technology makes SSDs in a RAID with hot backups unusable like a paper card reader.
@@capitalinventor4823 I once managed to „upgrade“ a fake 1GB pen drive bought on eBay to a total of 128.12GB. To do this, I cracked open the case and dropped a _genuine_ 128GB SanDisk micro SD into it... 🙃
Just like nautical miles are on a slightly different scale to regular bananas.
This is just like those 300000 dB horns for sale on ebay and whatnot, enough power to completely decimate the entire universe and all of it's parallels tenfold in an instant for just 20 bucks!
I wonder if one day these incredible ebay sellers will make a flashlight powerful enough to replace the sun when it dies in a billion years 🤔
It is indeed fortunate that humanity would never abuse that kind of power!
This flashlight is so powerful you should be careful about the recoil
He really should be wearing welders' goggles for safety. One hit from that beam and you're blinded for life.
The power of the sun in the palm of my hand
At 98kW that battery will last two-hundredths of a second. 😁
But the 23000 Amps will vaporize the thin cables even faster! So this has to be classified to be a bomb.
A battery with that kind of density would be much more powerful then a firecracker. 98kw is equal to about 23g of TNT... and the biggest consumer grade firework only has 50mg worth. It would go boom... and take your house with it.
Hey China, THANKS for the flashing mode on torches - thats what was so missing in the last 100 years and thanks for the 'economic' construction so that, despite it not havinbg an incandescent filament, if you drop it once the thing stops working permanently. Thanks, just THANKS!!!
On torches with those 6-pin drivers, some of them have a dedicated pin for disabling blinking mode. Ground that pin and banish blinky mode forever. I was trying to buy some of those chips (not easy) and found that titbit in the datasheets. It was almost a life-changing moment.
Love clive's delicate little hands😊

They'd certainly make *me* weak all over... 😍🏳🌈❤🔥😇
As a rule, I NEVER buy flashlights with non-replaceable batteries. It's just landfill-bound in short order otherwise.
A rule I also abide by, but one that is becoming increasingly difficult to uphold.
I usually follow the same rule with lights that I can’t replace the bulb. I say usually because LEDs have allowed a lot of creativity and some lamps are in shapes that could never be made with replaceable bulbs. But for any light fixture that could easily have a bulb inside and is made with an irreplaceable LED, I won’t purchase it. I know that the LEDs should last a very long time but that depends on how the company uses them for the background lighting and after approximately five years it stopped working. It was only on for a half hour after it noticed a person moving in the room, so far from five years of continuous use. After opening it up I saw that the first four or five LEDs at one end had burnt out. The company pushed the LEDs too hard and if I buy a light fixture I have no promises that the manufacturer of that won’t do the same. I’d like to replace the outside lights on my house. I’ve seen some very nice fixtures but unfortunately none of them use removable light bulbs.
Pending e-waste, just like Ear pods and every other similar product
@@_BangDroid_
I thought the business model for cordless earphones was that they would become lost way before issues concerning battery life showed up. :) It’s not uncommon to see one on the floor of public transit or on the sidewalk or platform nearby. Somebody rushes to get off or on a bus/train dropping an ear pod and they won’t stop to pick it up, if they even notice.
I apply that to ALL products. Very few cellphones have the option. There is a law suit for that right now and they are making progress. Nio is the ONLY car company making EVs correctly.
The power the Chinese can squeeze from a battery is amazing! Many years ago I bought a 2KW PMPO audio amplifier. All that power was supplied through a 12V 1A power adapter!
They call it power boost
You're so good at brute force an ignorance.
And peeling metal with circuit board trimers.
Thank you Clive, today is a good day for a smile 😊
I guess you don't do a lot of returns.
Exaggeration of capability surpassed absurdity many years ago, but still apparently increasing. I recall the days when it was possible to rely on the power output figures of music centre manuals, in Watts RMS. But then they changed it to peak to peak, and now it seems like they think of a number and add a few zeros.
I bought two audio amps a couple of years ago, rated vaguely at 1200W. Recently while the covers were removed I checked the output transistors - which were rated at a more realistic 100W
Same thing with solar garden lights, the packaging will always show a blindingly white light being emitted many times brighter than you will find you get from the lights!
Those were watts p.m.p.o. A pathetic "marketing" tactic which replaces industry-standard ways of correctly measuring output power with whatever stupidity gives you larger numbers, to try to trick the buyer. Still, not as bad as planned obsolescence, which is like some kind of anti-engineering to deplete non-renewable resources much faster. Just reminders of how greed can drive mankind into crazyness and stupidity.
At 98,000 Watts , this should bring down enemy drones with ease ... ( ? ) ............... DAVE™🛑
When the red charging LED is brighter than the actual flashlight, you know we have a winner! 💯
That J3Y transistor must contain some brand new super secret chinesium technology. Switching that awesome 98kW LED and not even getting warm... wow! 🤣
MOSFETs are pretty low resistance these days, but yeah, perhaps not quite that low.
I think the cable is special one too. We have sleeped to long

Hello mister BigClive
You call it "brute force and ignorance"
I think the Danes call it "British craftsmanship".. 😂😋🤗♥️
May the force be with you,Clive...
How does this come out? Pull. Oh, it's out.
Not even the best that China has to offer, can match the power of a determined Scotsman! 😂
I really likes flashlights and i love when you upload a flashlight video have a nice week Clive.
А видео только сейчас выложено😮
Only slightly? I best stick around for this one 🍿
I love it when you throw subtlety out the window and put on your striped apron to dismantle things. They must have very small kilowatts in China.
"It's out..." Excellent!
Thank you so much for making videos of random china stuff. I love that so much! Even if I mostly know nothing much about the "Scheemmatics".
"It's brighter than the sun, Lynn!"
Very nice video, I enjoyed the humour you added.
So, if it gets any rain on, or in it, it'll never come out agian, great!...
Nothing to stop it getting twisted and snapping the wires to the led off the board either
160mah?still 16 times bigger than what was in my smart meter!
"Slightly exaggerated power rating" 🤣🤣
Wow that's really powerful !
Wow, I can't believe you didn't put on appropriate PPE before handling that death beam. What are those power wires made of? A new superconductor material of unknown origin ?
*Chinesium* 🪨, probably... 😉
This surely comes from the same factory that also makes the infamous 600 dB car horns :-D
The one who also makes 1 billion volt tasers
Pfft that’s nothing compared to the 900dB horns you can get now 😂
LOL and what's the theoretical maximum sound pressure possible in our atmosphere? Something like 180 or 196? Gosh not only are these sellers boneheads, but they expect their buyers to be also. Bonehead-to-bonehead marketing I guess LOL
I have a similar, yet grossly less powerful lamp and unintentionally disassembled the sliding focusing bit in in a similar forceful manner. This also detached the led wires from the board.
I was able to remove the cell via inertia(this involved the wires from it being torn off as well) and used a wooden dowel to punch the switch/charge end cap out from the inside without damage.
After all the bits were extracted and connections repaired the light was reassembled and continues to function to this day.
I’m holding out for the 98MW version.
I have a fairly similar one.
Got one for my gran and was impressed at the £4 price point.
Mine does have the obligatory SOS mode when you hold the button in.
Pretty bright too, was using it to find my way to a rave in the middle of a forest.
might see if I can change the battery out with one or two of my street lithium cells.
The ones with 3xAAA in the holder will almost take a street lithium 18450. They're just a tad too short and need a bit of padding to fit snugly, but that's easily solved. Twice the capacity of most NiMh as well.
That's pretty close to interest territory of Photonic Induction!
I recently bought one of those radio transmitter kits, it was advertised as having a 50 milliwatt output but when it turned up it stated 50MW in the specs on the construction sheet that came with it. It's a real feat of engineering how much it's little output transistor is capable of, I will have offcom kicking my front door in with fifty million watts and an eye watering electric bill.
I run an escape room and I want to have a system where shining a UV torch on a puzzle will give you more context to it, so rather than just explain everything to kids over a clue, they can look at a picture that is invisible to non-idiots. I wanted a way of building my own rechargable uv torches and that schematic is going to help me loads!
Ask on r/flashlight for a suggestion based on your requirements. It is a good community, and someone would be able to advise a model that matches what you are looking for. There is a lot of modding advice too, with advice of what base to use it you want to fit your own LEDs.
UV LEDs can be tricky to get right though, as many „UV“ LEDs tend to emit the wrong wavelength to make UV ink show up as desired. A backup plan - If you want one - Might be to provide red or green LED torches and paint the clues in the opposite colour (So green paint, if red torches) obscured by patterns in the same colour. 😇
You'll be familiar with this idea if you ever used 1st generation 3D glasses. 🟢👓🔴😇
Thank you.
It's 10 times the power of my electric shower 🤣🤣🤣🤣
Does it come with its own inverter Clive ?😱😱😱😱😱😱
i love it how big clive draws the lil arrows out of the LEDs like =3
It's actually quite clever industrial design.
The way you open some of these items reminds me of those old fashioned tin cans that have a "wingnut" that you twist to peel away a metal strip to open the can.
Wow you could see that beam from the moon!
THAT CASING STARTED TO FAINT WHEN IT SAW YOU COMING!!!
I'd bought three copies of a single-AA-cell flashlight from a local store, a few years ago, and had to modify ALL of them because they didn't have a wide enough beam. Fortunately, all metal, so I just needed to unscrew the ring holding the front lenses on, slide a ring made of aluminum wire in behind the LED's backplate, and close everything back up again.
Now my only complaint is how dim it gets when the battery gets halfway used...
If I'm not mistaken the most powerful commercially-available "flashlight" is something like 1kW, is much larger, and has cooling fans. 98kW is an order of magnitude than even styropyro would do.
Wow! I'm going to get me one of those.

I feel your level of sarcasm has risen to another level. 😂 i like it.
Our local Heritage Railway at Christmas time runs the Pola Express theme and the company who runs it gave away flash lights almost the same as your flash light and I have one. It has a main light and a side LED light. So press button once it's main beam with a siding bit to focus the light. Press twice and it strobe light. Press three and it's the side light. It only has about 50 minutes of light before I have to recharge it. But it was a free
These lumen specs are like the range in a Tesla. But, I just purchased a Lumintop® GT4695 flashlight recently and remembered your video. If you get your hands on one, you might enjoy the advancements in their circuitry and design.
Hi Clive, Great video as always. I must admit to liking these little torches and have quite a few.
I was wondering if you could help me find some good quality solder wire leaded at a decent price. Most of the cheap solder on eBay is crap (sludgey and dull with a high melting temperature), but the quality solder wire seems outrageously expensive at over £50.00 or more for a 500 Grams Reel. Do you know a source of decent priced quality Solder Wire?
Many thanks Clive.
Keep well and stay safe,

Finally! A weapon to surpass Metal Gear!
A beam of 98Kw of light is what you see when Aliens beam you up into there flying saucer.
I'd advertise it as a 0.098 MW light. :)
As a European, 98,000 Watt is, well, just shy of 100 watt. Keep in mind that we use the comma as the decimal separatator instead of the US customary thousand separator.
And while that is _wildly_ off the mark for this form factor, getting 100 watt-ish output from a high quality 18650 cell is not that unrealistic.
It's a shame we didn't get a measurement of the current through the LED, because I suspect it's not even 98mW!
Current? He'd be lucky to find a whole Rasin! 🙃
You need to get a c-clamp style tubing cutter, like what's used for copper pipe. That would make short, clean work of things like this.
It's a typo. It was supposed to be a "m" not a "k" 😂
98kW -> 98mW
Apart from the underspec battery it's actually quite a nice product
I always wondered if a good quality cell would kill the LED as it packs a "little bit" more punch into the circuit when powered on. I have several cheap USB rechargeable lights, just like that, for emergency. They do their job well, even after a few years, but I wonder if the LED current limit is done by the usage of 800mAh 18650 cells 😊
Maybe it's 98kW EIRP (Equivalent isotropic radiated power), incandescent equivalent, using whatever method they use to rate shop vac motors at 6.5 horsepower?
In other words, what is the power of an incandescent bulb that shines in all directions with the same brightness as the focused beam of the flashlight, but at initial power on when the filament is cold and draws more power?
It's a shame it didn't come in your trademark fetching pink.
The BLF A6 is my go-to flashlight, developed by budgetlightforum users, sadly discontinued so bought 3 when I last saw them on sale.
A very tough 18650 powered Cree driven waterproof torch, the single click switch which has some nice features by half-pressing the button for 0.5 seconds; 7 brightness levels, strobe, battery charge level (1 blink=25%, 2 blinks=50% etc.), and a bike flashing mode.
Of course a light designed by committee has strobe
@@_BangDroid_ Lol.
I have several 1600 lumen BLF A6's. I LIKE em also
I was looking forward to a maximum power test on the LED. Just to see what the max sustained power it could handle was.
I suspect the controller PWM limits the current.
Brute force and ignorance. I love it.
Nice.
I bought this exact torch but in black. It was reasonably cheap, but not cheap enough. I bought a Sofirn SC18 at the same time and I will say I the Sofirn is *amazing* value for money, while with this thing I felt was terrible value.
I, of course took mine apart too. Managed to get the end cap out by leveraging from the charge port.
I had a great laugh at the power of that amazing flashlight. Given that 100kW laser systems are used to cut metal, etc., and are the size of a large pick up truck. I’m just impressed by the micro miniaturization that they obviously managed to accomplish. 😂
I needed a torch last night.
Walked across the living room and stubbed my foot on a metal trident.
It was a toe sting fork.
Was that a glitch-in-the-Matrix 'one moment, please' at 1:34? I've got a couple of similar-ish torches to these, but that take a single AA. They also show a very sharp LED pattern when zoomed out. Mine aren't 98kW though. I think you must have stopped down the camera to f1024 or something otherwise it'd be Day of the Triffids tomorrow for us all!
to be fair: i got two of them on ali just for the good focus....

It does amuse me when eBay sellers quote silly numbers. Can you imagine the cooling required for a 98kW LED.
Thank you for showing a way to open this lamp!
Now I know how to open my lamp without damage ... hopefully.
The charging is medium smart. Over the 100 Ohm Resistor there is a current flow and this activates the transistor. With one pin it measures the voltage and if this is ~4.2V the pin which is going to the base of the transistor is switching to GND, so the current flow stops.
Stupid is, that there is no current limitation, only the limitation of the power-supply and the wiring. With 160mAh there is very easy a overcurrent and very fast charging. Not good. It is worth to open this device.
How can you possibly know the safe charging/discharging rate of this battery with just its capacity?
In fact, there is a correlation between the two that suggests this quite large battery with an unusually low capacity is made for relatively high current like 5 or 10C. That's how a standard 18650 sized Li-ion like a Sony VTC6 can safely output 40A.
@@PainterVierax -
1. This is a China LiIon-Cell. Mostly there is a old laptop cell in this lamps.
2. For this price you do not get a high quality LiIon-cell. If you know china and chinese products, you would not believe that they put a very good cell into this lamp.
3. A very good LiIon-Cel for high current has only 1600mAh, the cells with a higher internal resistance have 2000 or 2500mAh.
Even if they use more copper to reduce the resistance, then the electrodes are not better. With a high charging current you create always Lithium-dendrites. The cell can handle the current, but it get damaged too.
The discharging with a high current is not a problem. There the more copper make sense.
But this device do not have a current limitation, only the resistance of the cable. This is not safe.
I would have liked a close up look at the LED itself. These high power LEDs are expensive and worth a closer look.
Perhaps the space for the extra LED near the charging indicator is to hold an LED to indicate the power is on. If the company may use the board for more than product then the need for such an indicator may be required. An LED to tell tell the user that a flashlight is turned on would seem to be rather redundant. (Unless the flashlight was emitting non visible light, such as infrared.)
Looks like a torch to me.
torque test channel Need to test this!!!
I have a small torch that defaults to lowest setting, which means I do not flashbang myself on shiny metal parts!
These small flashlights are all the same. I bought a couple of these a few years ago. They look different but the insides are identical. They don´t last very long but they are a great help.
So, the 160 mAH battery discharges entirely in something like 1/100 second? That would be ... exciting.
I've heard that 160 kWh Tesla batteries are capable of the same thing, now they have UKCA certification... 🔋🧯🇬🇧🔥🔥🔥😉
