Resurrecting dead power banks from Russia. 

Thank you for the video, it was a great watch! Nice to see nothing exploded during shipment. Glad to be a provider of nice tasty and engineering goodies for you and youtube! The caramel inside of the pryanik, i forgot to mention, is indeed baked condensed milk. For Cellevo the processor crash sounds more plausible, i tend to keep batteries charged. (Or, the rate on which the unit self-discharges must be really high for that particular power bank) Surprised how simple was the issue with Xiaomi, quite a fail considering the higher than usual price.

the "design" of the letter is awesome. very reasonable and technical. a smart mind i assume.

Mikhail, that was a wonderfully drawn map, and a lovely painted(?) postcard!

Complimentary MOSFET: "My, that's a *lovely* shirt you're wearing today!"

I fully endorse the Big Clive Food Channel. Occasionally Hot-dogger / SodaStream enhanced

Thanks for the video, bigclive! A couple comments, although I may be late to the tea party... I am Russian, long time viewer, sometimes commenter. So the guy’s name is pronounced “Mee-ha-eel”, it’s the Russian variant of “Michael”. The chocolate brand is a quite popular one around here and is indeed rather low on cocoa oils and whatnot. In general most decent Russian chocolate brands take pride in the low amounts of cocoa solids in them. The cranberry candies are an excellent choice by Misha, I recognize that box of pure bliss! Now the pryanik is in fact from the capital of pryaniks, Tula (pronounced “Too-la”) and goes great with a nice hot cup of tea (a dash of thyme for the pot makes it even more gooder), and us Russians are pretty serious about our tea, I prefer mine with a bit of milk most of the time. This dolce leche you speak of is a staple of Russian tea-time and most likely is the flavor you’re tasting on the pryanik. Many varieties come with this type of filling. Indeed it can be easily made at home by putting a sealed can of sweetened condensed milk in boiling water for some time, just make sure to not over cook it. The clean up is no fun. At all... So there... A little excursion into Russian sweeties and culture. Love your content! Thanks again for all the work you put into keeping us entertained!!!

Xiaomi has had their powerbanks ripped off so many times it's nice to see the originals, my trio of their "10,000mAh" ones are still working well 4 or 5 years after buying them, containing 3x Panasonic 18650 cells a piece, really good powerbanks, and rather cheap at the time (when the $-£ rate was in our favour!)... :)

This is why I love this channel. You get fun electronic stuff, but also get to see interesting foods and drinks from all over the world. I loved the little painting and letter drawings too, a great personal touch

the first one is Xiaomi powerbank, cheap but very high quality among products in China. The logo is so funny "MI", you can look as Chinese character "心" if inverted. Lastly, i want you to explore Xiaomi usb charger, with comparison to other chargers, because Xiaomi usb charger get a high recommendation from our Hong Kong Consumer Council.... i really want you to explain the circuit they design 🤤🤤

Personally I think they should make gluing batteries in like that illegal. It makes recycling the battery at EOL almost impossible. - Sooner or later there will be large scale recycling for lithium ion..

I have the exact same Xiaomi Powerbank and it had the exact same problem. After soldering the wire back on it worked flawless for the past two years now.

Nice to see those Russian treats! Though I cannot speak a word of Russian to be frank... Also good to see that you managed to rejuvenate those power banks :) I've got a "300,000mAh" power bank that has a broken USB port, a non functioning solar panel and a broken LED so that may be worthy of a teardown just to see what the real capacity of the cell is (obviously not 300Ah!).

big Big BIG👍Absolutely love this channel!!...technical...personable..international...and Mikhail..beautifully composed letter...and the picture of the tower in Moscow...is that an off the shelf or was it something you had created...really enjoyed the attention to detail Clive with the confectionery...keep it up mate..a big shout to all Big Clive fans from south east London LALALA 💎👍👜☢☣🕺💥

Hey faquoka you too !!!!!! clive. 😂🤣😂🤣😂🤣😂🤣

The fact that you know how to do this, would make you the most valuable person in a mad max distopia.

Good thing you took up electronics, Clive. If you'd been a surgeon, you'd have a house full of zombies by now. ;)

That ginger bread cake looks delicious... I love things like that which aren't too sickly or sweet!

I do envy you for all the great things folks send you from all over the world, it looks very interesting.

"The batteries are glued in." *Bring me a heat gun and a stick.*

Hey Clive, the reason why some American chocolate tastes different or has a different texture is because it's not actually milk chocolate - it's called "compound chocolate" which is chocolate, but instead of cocoa butter, they use other vegetable fats (usually palm oil) for the "solid fat" aspect required to make chocolate.

Chocolate-corner with Large Clive is something I would pay Netflix for.

Good job Mikhail! That Pryanik had some cooked sweetened condensed milk inside.

Привет из России! Hi from Russia!

A nice post, especially the extensive letter and gifts.

My usual workaround for over-discharged cells is to just hook them up to a powersupply that's at about their nominal voltage for a few minutes and then put it back on the regular charger. Similarly overcharged batteries get to power a fan for a little bit until their voltage is back under control. Of course take all pie tin related precautions :)

Clive, you should send the poor sod his banks back, having provided foodstuffs and great content! Nice video. :)

Awesome video, Clive, enjoyed the intro section and main dissection!

Clive, thanks for another great video. How might I be able to send you some solar surge arresters to take to bits?

I Shukhov tower is a design classic. Circular without a straight beam in in. quote "The Shukhov tower is a hyperboloid structure (hyperbolic steel gridshell) consisting of a series of hyperboloid sections stacked on one another to approximate an overall conical shape. The tower has a diagrid structure, and its steel shell experiences minimum wind load (a significant design factor for high-rising buildings). The tower sections are single-cavity hyperboloids of rotation made of straight beams, the ends of which rest against circular foundations. "

Hey Clive! I know you're into electronics more than old school computers, but CuriousMarc has a series on restoring a Apollo Guidance Computer, an old computer before microprocessors. Truly fascinating. At least for geeks like me... :) Got any comments in general on Space? (The 50th anniversary of the Moon landing is in a few days...)

We need Big Clive Merchandise now. It's a great video once again, and thanks for Mikhail for the postcard and otherbits, awsome job there! :)

The MI is a usb powerbank with quickcharge 3. Useful for powering a ts80 soldering iron to 9v. Also works with A+ 6 phone (and all te others I've tried it with. Seems to be qc3 compatible "by the Qualcom book" unlike so many of the reverse engineered chinesium knockoffs. Not found anything it's not compatible with.

The input range on that TI chip going up to 17 volts is probably to accommodate one of those new USB-C power delivery modes.

True about Hershey’s. Their plain milk chocolate is very harsh and leaves a sharp burning feeling in my throat. I like their other variants though, especially their dark chocolate. Some of the best chocolate I ever had was Belgian chocolate from one of those roadside discount stores that specialize in gloves, tarps, and random crap. It was huge bars for $1 each.

This story reminded me of my trip from the US to the Philippines. On the main trans-pacific leg, our plane had power inverters in the seats, but the ones on my row didn't seem to work. The guy beside me needed a charge, so I let him boost up off of my *absolute unit* of a battery bank. Specs below the fold. 127,000 mAh @ 3.7v new, fitted with a 5v1A, 5v2A, and a variable DC 9v, 12v, 16v, 19v, 20v 3.5A out for laptops. Is old and holds ... somewhere around 65Wh last time I tested it, probably less by now, and the status LCD is utterly rekt.

Those sugared cranberries can be nice, but just thinking about how it the feels to chew on the sugar makes my teeth itch. And every now and then you get one where the berry has gone bad inside and tastes fermented. Here in Finland I see them mostly around Christmas time.

Sugary balls lol.....I'm glad I'm still a young boy in some ways

Greetings from Russia! Was a subscriber from 2016, I think, not sure, enjoying your works A LOT

"The laying on of the hands" from our hero, Big Clive has done it again!! 😉 👍

Too many of these videos make me quite hungry and/or thirsty. 😊

I was born in ‘65 as well. I celebrated (mourned) my 54th on Monday.

"I tried this last night" Half of it already gone.....

About forty years ago or less, when they still did a lot of trade with Cuba, Russia had the biggest and possibly the best chocolate industry in the world. Their chocolate rivalled that of Belgium, Holland etc and was, reluctantly, accepted as being every bit as good. PS.... Excellent video. I learned something both new and useful.

Clive, your pronunciation of Fukuoka may trigger the dreaded bots. For future reference it is like "Foo-koo-OH-kah" (emphasis on the "oh" bit) Keep up the wonderful videos. I would love to see you get a Halo Bolt 58830 Jump starter / power pack / inverter (mine has a 65W 115vac, U.S. outlet on it.) and "take it to bits" then offer your opinion of it. I'd send you mine, but it still works great, and I use it all the time when going to garage sales and yard sales to test small appliances or radios etc, that I'm interested in. Lil' bugger even started a Chevy 350 (5.7l) V8 with a stone-dead battery.

Fukuoka is pronounced Fu ku, oh, ka. Your pronunciation of Russian and Japanese are both amazing! Thanks for the great content!

It's quite fun to watch the things one is quite accustomed to being discovered and tasted for the first time by someone else )

I"m curious what the capacities are, especially for that second pack after it has sat at such a low voltage. You hear people screaming left and right about discharge protection, etc. But what is the actual, measurable effect? And does it really "kill" the cell beyond being usable? Clearly it was still holding _some_ power after you slow-charged it..

Hey Clive love your videos, there very informative and even if I'm too busy to watch it's great listening to your dulcit tones in the background. Anyway I've been wondering why bulbs blow more often in light fixtures that have multiple bulbs? We've had this problem in different houses with different fixtures. The current bulbs were all replaced less than 3 months ago 3 incandescent bulbs have gone already and only the 1 LED bulb has survived (only had 1 on hand at the time)

My wife murdered her powerbank by not recharging it when the power was either really low or drained. I replaced it with the exact same Xiaomi as the first one. I must now ensure she treats it a tad more gently (to avoid the teeny tiny wire from breaking) and to keep the charge up so it doesn't die like her first victim. Maybe I will attempt to explore the dead one but the case appears to be glued together and I would likely destroy it when disassembling it which would null and void a usable repair. I purchased the Xiaomi one because it has a Mode C charge connector and the idea was to eliminate the micro USB cables from her travel case (her phone is also Mode C). The Xiaomi is also a lot lighter than the previous one which has, I believe, the 1822 (or was it the 1865) "laptop cells" in it.

The zoom of your new recording device makes the image very grainy. The previous one had a very nice image, even when zoomed in.

Сувениры прямо как в поле чудес.

Flown 2 Moscow plenty of times - and have always bought bk a bar of alenka chocolate and a bottle of sovietski "champagne " - great souvenirs and tasty 2

Finally someone actually pronounced the word Xiaomi right

This is my favourite food channel.

Dutch gingerbread is called "Speculaas" and sometimes: "Peperkoek", and traditionally served around "Sinterklaas" and Christmas holiday's.

If we discovered immortality but were limited in the people that could receive it, this guy would get my vote.

I have a semi-dead powerbank here (OK, a couple years ago, it was semi-dead, now it'll probably be dead all the way) which was once a 10,000mAh unit, but only delivered something like 200mAh, while taking bout ten times as much for charging it. Unfortunately, it's in a case that is welded shut, so there's no way of accessing it without total destruction.

12:22 The data sheet for the TI component apparently talks about a 9A output! Am I misinterpreting this?

No. :))) Sbiten should not be mixed with vodka. :))) In fact, sbiten (сбитень, sbe-e-tjien') is much older than vodka, and is THE true traditional russian drink, along with kvas (квас). Vodka has been produced in Russia starting from somewhere in XV sentury, and some say that it was actually imported from Poland. Anyway, sbiten and kvas were produced almost forever - for example, kvas is known to be well appreciated and mass-produced as early as in XII sentury. Speaking of traditional alcoholic drinks, these were called "mjod" - which literally means "honey", as it was the base for them. Unfortunately, by XVII sentury this traditional beverage was almost completely replaced by vodka, which was cheaper and easier to make.

Those Xiaomi power banks, at least the newer ones with QuikCharge, are quite good - they have very low ripple on the output, have a feature to keep the output on on low load, and even understate the battery capacity..

Tula is where they make most of the Russian ammunition, too.

Clive, have you ever taken a look at the battery packs for ebikes? I bet you can pick up a dead one from your neighborhood bicycle shop!

Love the video! I would like to know what system you use to provide a battery with a current limited supply. Have you built your own PCB for charging or is it a device that I can buy from eBay or Amazon which regulates current flow? Thanks!

The word -Fukuoka- 'Fukuova' springs to mind

That radio tower is actually quite amazing, and iconic. I think I remember hearing they were going to pull it down? But there was a lot of opposition because of its historic and aesthetic value. Is it still standing? Not sure.

1:34 is the moment the omnipotent RU-vid AI decided that a naughty word was said, and this video lost any and all monetization. ;)

I love your videos Clive, and i especially like your 'spudger'. What a brilliant tool with a brilliant name, except with your accent you should be calling it 'The spudger of doom!' thanks again for some great and informative videos :)

You should start using that Xiaomi powerbank as your main powerbank, at lest for videos.

I have a mystery power bank that stopped working mysteriously, you want to check it out? Or is your pile not getting any shorter? 😅 Did you send them back now they're fixed or are you going to be crafty and keep them 😂

I'd also like to thank the Russian contributor for the interesting powerbanks ... Along with the unusual treats.

Cool thats some nice chocolate I had some when I was in Moscow last year !

"Hersheys which is like wax" You must try some chocolate brands here in Philippines theyre like candles 😂

Here in the US, our "beloved" Hershey's chocolate is awful, not only due to the texture, but because the recipe is based on spoiled milk. Fortunately, we can get good stuff at independent shops. It's also not hard to find European chocolate here.

приятно что уделил внимание и россиянской аудитории твоего канала

Hi Clive, maybe you should measure the leakage current of the electronics? Might be able to understand why it discharged so low. Perhaps the micro dies at .9V? Great video. Thanks.

Amazing card! Love the map!!

That 5000mah xiaomi powerbank takes me back to the good old days, it's the first generation of xiaomi powerbanks, in that same size now they have 10000mah ones....

Those are very odd-looking cranberries. Fresh cranberries have voids in the interior and white separators between them. When sliced it looks like a cross shape. perhaps they were dried first, but you said they were very moist. 1965? You young pup!

My thoughts on the sugared cranberries, never having tried them and only just now looked up a recipe: since cranberries are hollow - they're filled with air, so they're harvesting by flooding the field and corralling them on the surface - there's enough space to fill with the sugar syrup you coat them in before rolling in powdered sugar and leaving the outside to dry. If the berries don't perforate, osmosis alone should leak sugary liquid into the cavity (though that leaves me the question of air pressure). But then it depends on who makes them and what exact recipe they use. Maybe that particular version/manufacturer aims for that result. I should get ahold of some of these and examine them closely. ;) (Or wait another month and start buying fresh cranberries on sale to make my own variations.)

I remember an Eastern European friend telling me about what they called "communist chocolate" from the USSR era, which contained no coco solids at all! Still sounded preferable to Hersheys!

Man I’d love to see some update videos on some of these reanimated/resurrected simple fixes like this one, the neighbor’s tv, etc... Maybe you’ve already done them & I just haven’t made it that far yet, but if not, it’d be great to see if these failed again or not.

Wow what a viewer! Love your channel.

I've looked at a lot of these types of devices. The chips on the back are likely current sense chips. A battery bank like this will have a chip for each function and they add up. A microcontroller for input logic and integration Monitoring, current sense and overload protection on the battery. Current sense and limiting on each USB-A port or USB-C port Boost converter for output sometimes controlled by the microcontroller but usually separate Fast charging handshake. Not really sure why these aren't built into the microcontroller but they are typically standalone.

If you keep drinking that liqueur, it's gonna have you speaking fluent Russian in no time!

Well thanks Clive today I got up and said to my family today I going on a diet... Now I want chocolate.. dang it!

fixed such a powerbank that had liquid damage. opened it, washed the pcb with water and then alcohol to get the salts off and dried it with compressed air. started working again

WOW, I always wondered how old you were so we were both born the same year. Gen X.

Hershey's also is processed with Butyric Acid, which gives it that characteristic flavor that most europeans seem to loath

OK, Clive now that you fixed those power banks are you going to send them back to Mikhail in Яussia? 😉

Americans will be confused on your "smarties" reference! Americans: imagine if M&Ms tasted good and you have Smarties!

Possible glued battery liberation technique tip. I know a pro trick to remove car brand badging attached with double-sided tape is to get behind them with a length of dental floss and use a sawing motion while pulling across or down releasing the badge without damaging the car paint. If you can somehow get a line of floss behind a glued battery on a product you really want to repair or inspect without damaging the battery, you should give it a try. Hello from scorching hot Florida. If we're not getting burned like ants under a magnifying glass, the thunder storms are trying to kill us.

А я всё ждал когда ему пришлют что-нибудь наше

I have one of those Xiao Mi Pro powerbanks since new (over 3 years now), it's a great product, I use it as a parking battery for my dash cam as it allows pass through charging, so while the car is on the Xiao Mi charges and powers the camera and while the car is off the camera is powered seamlessly. If it ever stops working I'll know where to start looking!

Eating off the bench, I see you got a chance to take your lithium.

1965 was a special year for you and me and Charlie Brown and Charlie Sheen and the Super Bowl.

Surprised how complex that Xiaomi power bank is - I have 2 of the 10000mah variety of the same unit and they can be sourced ridiculously cheaply, at least in Australia (16 AUD / 9 GBP). Capacity has always seemed accurate and the build quality good. The 10000mah has the same build as the unit you recieved, but with an additional USB output.

You'd think they could have quite easily designed a bootstrap circuit that started the micro off external power and then carried on as normal. This quite effectively limits the shelf life of the device, if it's one of those things you only use in an emergency, it's perfectly feasible that it would fail when you need it most... But hey, there's a reason I'm not employed as an electronics engineer, I guess.

“ Yeah,I like watching Big Clive doing Philosophy Aswell✍️

Hi Big Clive - Special Request - Can you do a video on wire nuts? Do you recommend the use of wire nuts? Are wire nuts an acceptable method of joining cables? Is there any situation where they cannot or should not be used? Love your videos!!

Wooow that thumbnail had me worried about you at first Clive :D I thought they've captured you ...
