You are one of the few that can make videos about Temu's chinesium products without anybody fearing you are shilling. It's just a continuation of the long-ongoing series of looking at the guts of chinesium products, possibly in pink if available.
It's nice to know that there is such a thing as an "emergency night market" for those people that need to go to the market suddenly in the middle of the night😁
It is crazy how china builds these devices so cheap. Also, you’re almost at 1,000,000 subscribers! I would love to see a desk tour when that does happen. Thanks for these awesome videos.
It is important to learn why, because China jas had some successes and some failures but if we learn the nuance's globally we can adopt what worked and abandon what did not globally for a net good. interactions between state owned systems and maufacturing centers and capitalist corperations really are the star winner in the price reductions China is capable of. We tend to think its just lower wages and saftey standards, but those are complex, my family has a history of traveling to China for thier significantly *HIGHER* wages then back to the USA for living where we dont stick out like sore thumbs. And thats fairly typical for manufacturing positions that require a degree with years of training and support lower tiers of entry. But because many of the manufacturing facilities are owned outright by the goverment actually getting your idea mass produced has a much lower barrier to entry However, the local labor has a mindset of "what is the cheapest/fastest way to build something that does the job" instead of a balanced mindset, or a long term mindset like most other robust producer countries. One that is slowly changing but it makes sense for the recent history of China gearing up for fast/cheap high value low effort export production to get food trades from the US during a minor famine; whom now supplies a sizable portion of China's calories, mostly in corn, chicken, and soybeans. So with that part I think looking at manufacturing plants the same way western countries look at public libraries is a win/win for everyone. but There is still cheaper average wages And part of that comes from all land and buildings are owned by "the people"; really the goverment its just leased for truely brand dedicated manufactruing plants, with it being a human right to be allowed to stay in one residence, you cannot be evicted for any reason even the good of litterally everyone around you, but your earnings can be garnished if you refuse to pay, so no homeless, but some really weird city planning. Its another thing they do that is a nuanced win and loss, it does allow people with common skills to have a better quality of life but it also allows Capitalist frameworks to easier abuse the situtation and have people with common skills work for significantly less. Therefore I think it is fair to say that the outlook China takes is not quite balanced, really things are only valuable because we humans decide its valuable; the market of consumers is what allows any other market so I find an true UBI ideally shared between many nations or all humans to be sort of the solution to finding balance under a monied system. Because being a consumer adds the value to the product, being a consumer is a vital role to all economy and should be paid; but you could and should particiape in advancement more, so by levying a (honestly rarher heavy tax) on all profits and distributing them equally nobody can be taken advantage of. And its a weird thing that FIAT money does that, that it takes being a consumer and makes that truely vital; we as a global society should look into other trade systems so that cheap junk does not ever have value.
china abuses the UPU (Universal Postal Union) which offsets shipping to poorer/developing countries to be SUPER cheap and making it more expensive to other countries, including Lithuania (where i had to spend $18 to ship a tiny CPU cooler adapter, a 50g/1.6oz SCAM4-1000B)

@@jmrI'm guessing the named adapter handles the power negotiations without passing data between the sides . If it was really good it would even do voltage conversions if either side has a higher wattage setting . Basically the power input side would negotiate whichever volt x amps combo delivers most energy, then the output side would contain a switch mode DC-DC converter to output that energy according to load preferences . For example if the power source offers 200W at 40V x 5A but the output only wants 20V, the adapter would output 20V x 10A, but any combination in the various specs would be handled, from USB 1.1 lowest power mode to USB 4.x highest power mode with neither side knowing anything about the other . It should even be designed to survive "USB killer" products .
@@johndododoe1411 That model is as dumb as possible. It's just the data wires cut but my question had nothing to do with that. My question is why doesn't the smart charger fall back to dumb charger spec. That's supposed to be the default when higher voltage or higher amperage can't be negotiated.

A modification idea: We Need something interesting for Electroboom to play with... I'm sure he'd like a Tesla Coil LED carabiner lamp that's rechargeable.
Hi, just wanted to say thanks for the heads up about the incredibly cheap UV phone sterilizer from a few weeks ago. It's true shortwave UVC light (about 50-60 milliwatts optical output) at 280nm with a FWHM bandwidth of 10nm as measured on an Ocean Optics spectrometer so it really is sterilizing things, and because there are no annoying visible light "warning" LEDs included in the UVC emitters it produces extremely clean UV light for illuminating fluorescent minerals (you can see my review and images on the product page). For an unbelievable $6 it's the cheapest source of clean UVC light I've ever seen. What a great find! I wish you would revisit it to see if it's hackable to easily increase the LED power!
@@Muonium1 These might be obvious but a couple things to consider. If the design is running the LED close to its max power, increasing the current through it could pop it. And running it at higher power will definitely reduce its lifespan. I would like to hear how it goes!
I decided to check the battery in my multimeter. It was a PP3 and measured 9 volts, so it was good enough. While I was at it, I checked my 1 KHz sine wave generator, transistor tester, capacitance tester, ESR tester, computer mouse, torch and remote control for the aircon. Three of the battery cells were oozing! If I'd left them any longer, the spring terminals would have started to corrode. So here's my suggestion: right now, before you forget, check every dry-battery-powered piece of equipment in your workshop, house and car. In some cases you can replace them with rechargeable cells, which won't leak. You can thank me later!
This thing would have been ~30% more efficient if they used 20kHz pulse duration modulation on the output with an LC filter for current limiting, a shottky flyback diode instead of current limiting resistors and a FET to eliminate the base current along with reduced CE/DS voltage drop.
@@snufftherooster93 What I described is basically an open-loop buck regulator. This only works when you don't care about regulation against battery voltage and load changes, the load being constant (give or take a bit due to battery voltage) in this case.

Very nice, I expected it needed the vice of knowledge to dismantle. Would be interesting to investigate more if it is a new low capacity / fake AA lithium battery or a reused worn out cell; compare the weight and open it etc.
Yes, I had the same question. That would be Interesting. When I bought my first 14500, I found offers for 1200 and 3000mAh on Aliexpress. I knew, that 3000 is impossible, so I ordered the 1200 offer. It had only about 300 or 400mAh. Trash
This one is sort of exciting from a hacking point of view. I'd like to stick a good battery inside. Perhaps copy the design of the base and 3D print a version meant for an 18650.
Nice looking light, but not much use for camping! I'm glad I bought 8 of the Q6M camping lights you showed back in 2018. They last for 450 hours in "night light" mode! They are no longer readily available sadly.
Thanks for that offset pins to create a spring effect info, I have a light with the same arrangement which fell apart and I wondered which holes to use to replace it🤪!
Could you show us some hacks of this light maybe put one of those lipo/li-ion rectangular cells inside for more capacity. Shame it's got such a small cell. Great video as usual
2nd order this week to TEMU then, gotta have it to upgrade using all the vape cells i've been collecting from people! thanks Clive!, wife is going to say, not ANOTHER lamp.
I'd love to see a vid of making these modifīcations and the before and after results! I'm not terribly good when it comes to dóing things like modifying such devices, though I'm capable with a step by step guidance such as you've provīded in the past. Yer a wizard Clive!
"What's the worst that could happen?" - Big Clive's Famous Last Words. Since it has a lithium battery inside I would say fire would be the worst thing that could happen. But then it would make even better content.
Clive, would this would be a perfect job for your 3D printer to make a larger housing for increased battery capacity. I'd enjoy watching you modify this light,housing or components. When you make the modifications videos I really enjoy those. I'm no where near being a electronic beginner, i am a step or two below that, so watching and believing I could do that is as far as it goes.
Yes. Not sure why that's always included to be honest, best guess is that the chips that run these are all the same because it's cheaper to make one chip than to make 2...
I'm curious about how you measured the voltage across transistor Y1. Was that using an oscilloscope? If you used a standard DC voltmeter, I guess you would get incorrect results since it is using pulse width modulation even on the highest setting.
@johndododoe1411 I think we're looking for some variant on the peak detector, something made with op amps, diodes and capacitors that follows the smallest voltage recently seen.
Would you consider a modification video on this? I would love to see you upgrade the battery, change the filaments like you suggested and change out the Y1 for a mosfet. That would be a very nice process to watch indeed. It may make the video longer than RUclips likes but I'd watch it!
@@fallingwater Less work to use a 26500. These can supposedly go to 3000mAh. I see on the bay you can buy them with leads already attached. Assuming it fits of course.
Hmmm, instructions said not to leave plugged into charger (does it work when plugged in as well?), but looks like the chip will stop the cell from charging once it's reached voltage threshold. Which is it? Other than not leaving these cheap usb things plugged into chargers when not being watched occasionally... :)
Regarding the cell, I'm torn. The capacity is just sad. I am all for recycling but I am not sure if this is even still safe? Should be safe charged at less than 0.25C I think?
282mAh capacity and 4-6 hours of charging requiring a type C charger? Please tell me it uses Power Delivery and just assumes there are bad soldering joints, which would also explain that you have to keep a look at it while charging…
280 mAh for a 14500 is terrifying. Where are they getting sufficient "recycled" 14500s from? Is it just a 13400 (e.g. mass produced for disposable vapes) in a box? But they're 550 mAh even in that disposable use case.
They're likely cells that didn't pass QC, which to be honest is even worse than recycled cells in terms of potential safety. Also the small disposable vape lipos would likely be a great candidate for upgrading these. I've got a drawer filled with them, very useful.
Have you tried holding the button on for SOS function? there cant be chinese design product without SOS. Second point is how do you take 4 to 5 hours charging 260 mAh battery on 500mAmps?
yes, yes. but LED street lamp? how to make it on/off at my command rather than built in dusk sensor or 10 minute test circuit upon powering? 3 pole bayonet on top.
An ideal item to fill with discarded single use vape cells ! ( might be an idea to change to micro USB , like a lot of other rechargeable torches / lamps ( ? ) these allow most USB chargers ) ............ DAVE™🛑
Excuse my simple mindedness- but i dont understand the red and green led setup. If there is one resistor feeding both leds, the green always pulled to ground, and the red pulled to ground by the mystery chip, why wouldnt the green always be on? What is it about the red one coming on that shuts off the green? Sorry, i dont know enough to know what i dont know.
The forward voltage of the red LED is lower than that of the green LED, so with the red turned on by the chip, the common point of the LEDs is pulled below what the green one needs in order to light up.

A tip to get a device like this (without the resistors on the data pins) to work with a smart charger is to use a Portapow Data Blocker.

very interesting as always! will you ever teardown a paw-shaped rechargeable hand warmer (i found it on temu for about 4$)?
I'll take a look for that.
With all the rechargeable vape batteries i see on the side of the road, I feel like they should be used for everything. But no. Instead an aa?
Regarding the cell, I'm torn. The capacity is just sad. I am all for recycling but I am not sure if this is even still safe? Should be safe charged at less than 0.25C I think?
would they be any way to skip the 2 step diming part? just to have it be an on and off switch at the max output?
Only if you replaced the circuitry.
But will it stop Bigfoot.
Next video , please ad a better cell and teach us how to do it.
Disposable vape battery of that size is 600 or slightly fatter is 850mah
I subsequently put in a 1500mAh vape cell.
282mAh capacity and 4-6 hours of charging requiring a type C charger? Please tell me it uses Power Delivery and just assumes there are bad soldering joints, which would also explain that you have to keep a look at it while charging…
280 mAh for a 14500 is terrifying. Where are they getting sufficient "recycled" 14500s from? Is it just a 13400 (e.g. mass produced for disposable vapes) in a box? But they're 550 mAh even in that disposable use case.
They're likely cells that didn't pass QC, which to be honest is even worse than recycled cells in terms of potential safety.
Also the small disposable vape lipos would likely be a great candidate for upgrading these. I've got a drawer filled with them, very useful.
is Temu kind of like Wish??
@@Matt_Quinn-CaledonianTVuse temporary card numbers.
@@Matt_Quinn-CaledonianTV for stuff like this, I use "one time use" credit cards. I dont trust my real credit cards with shoddy websites
@@Matt_Quinn-CaledonianTVheard of PayPal?
where have you been clive i thougth you had runaway with the circus
I never left the circus.
Have you tried holding the button on for SOS function? there cant be chinese design product without SOS.
Second point is how do you take 4 to 5 hours charging 260 mAh battery on 500mAmps?
The charge time may be based on an original higher capacity cell or it may just be cloned text.
yes, yes. but LED street lamp? how to make it on/off at my command rather than built in dusk sensor or 10 minute test circuit upon powering? 3 pole bayonet on top.
If you own the street light you could get a spare photocell for the enclosure and then fit a remote receiver.
Are you sure its a lithium and not a nicad or night cell?
Definitely lithium.
I got a cheap temu glass electric kettle , it literally smells like a garbage fire even when cold and you can taste it super toxic lol
Lolz yeah I bought one of those colourful light projectors they have and it smells like that!
Although it could be a bit of a stretch, it also could be useful for other purposes going by the shape... :P
No safety flange.
An ideal item to fill with discarded single use vape cells ! ( might be an idea to change to micro USB , like a lot of other rechargeable torches / lamps ( ? ) these allow most USB chargers ) ............ DAVE™🛑
Excuse my simple mindedness- but i dont understand the red and green led setup. If there is one resistor feeding both leds, the green always pulled to ground, and the red pulled to ground by the mystery chip, why wouldnt the green always be on? What is it about the red one coming on that shuts off the green? Sorry, i dont know enough to know what i dont know.
The forward voltage of the red LED is lower than that of the green LED, so with the red turned on by the chip, the common point of the LEDs is pulled below what the green one needs in order to light up.
Ah! It all just clicked in my head now... Thank you for explaining!
Don't filament light bulbs need be full of nitrogen to not instantly burn out?
Sometimes an inert gas like helium. But these ones run at very low power.
@@bigclivedotcom ahh okay, that makes more sense
