Just repaired an Anker pack which stopped working after a few days. Anker were good enough to send out another foc so the faulty one stayed in the draw for over a year. Decided to take it apart the other day and that was a struggle, it had two cells which had been glued into the bottom and lid of the case. Turned out to be an easy fix, the strap that joined the + and - of the cells had broken. A quick zap with the spot welder and it was back to a working pack. Took longer to get it apart than it did to fix it 😃
Nice 👍Yes I did an Anker one too a few videos back. Most of these power banks are a nightmare to get into, and as you say often it takes longer to get into it, than repairing it!
Another interesting video, thanks. Prompted me to dig out a faulty power bank I had looked at, and failed to fix, ages ago. Discovered a short circuit ceramic capacitor, same as you, and with that replaced, it now works just fine. So thanks for making these motivational videos.
I can't tell of you're a electrical engineer trying to be a youtuber or youtuber trying to be an electrical engineer because you are exceptionally good at both. I think you had doubts about this one, but you nailed it.
Hello, I look forward to every video from you. I discovered your channel back when you were repairing a Milwaukee tool. Since then I have become a big fan because you do your job really well. Please keep it up. Greetings from Germany😀
Glad to have found your channel, I've tinkered with electronics off & on all my life, mostly off but now I have the time I'm getting back into it & can learn tons from someone as yourself so thanks for taking the time to video & post these, they are much needed for people as myself. I truly enjoy them as well as others I've read.
Thank you. I've done a few pretty crazy repairs on things, and even had to reverse engineer software at times to fix a problem. Like on the Solar Inverter I repaired and then needed a service password to change a setting ("no password no problem") is the title of that one, and recently the AVerMedia device I repaired. The FLIR thermal camera video was quite an interesting one too.
@@BuyitFixit I thinker myself. But after watching you , I realise A: I over think B: I need a proper soldering station. One iron i have could be used for cauterizing gunshot wounds.
Well done Mr. Buy it fix it! Whoa ! I got to say a job very well done again, o boy! o boy! when it comes to this intriguing electronic repairs well got say you are a true magician. Cant wait for the next video and keep well mate.
While repairing any electronic pcb, please show some tracing and reverse engineering stuff with multimeter continuity mode. I heard that we can trace whole circuit or a particular section to understand it's design and working that's help us to understand the issue once we got the design. But i don't know much about tracing hence i request to please while repairing things please do some tracing work 🙏🏻 I'm new to your channel and I fall in love with channel, I hope that I'll get much knowledge from you and channel ❤ lots of love from Mumbai India ❤
Those things are the hardest to get apart and back together without breaking the case .. they do not want them to be repaired it seems .. I can never get them back they way they were. Most of the time its a one way take apart for parts kind of deal .. but wow you did a awesome job .. amazing !!!
Another amazing repair, bravo. Your detailed trouble shooting is nothing less than exceptional, thanks for the work. How did the inside get so much corrosion when it was sealed so tightly?, that part is weird. Maybe from the USB sockets..IDK. Always a pleasure following your content. See ya soon.
Incredible fix! Without the thermal camera, I don't believe you would have succeeded. Your Country is beautiful. Coyotes wipe out Lambs in my area (Southwest Mississippi, U.S.A) along with coccidiosis. Great Pyrenees are a must have or a mean donkey.
Nicely done! I started repairing things myself a few years ago and managed to fix a lot of things already. I'd like to learn more details about electronics like mosfets, transistors etc. to be able to diagnose more complicated problems in the future. Do you know a website where I could learn more about this?
Great video as always Mick, but there's a disturbing lack of doom installations on things 😅 how's the lambs doing? But as always keep up the good work and looking forward to seeing more 😊
Another saved from landfill. I suspect the backstory on that one is enlightening (whilst listening to my phone in the bath I). If the case is ABS, you can use Evostik PVC pipe weld, but practice first and the case will not come apart afterwards.
Thanks 👍no, that's pretty accurate. I've not done any courses or anything and most of the stuff I've worked out myself or picked up from other people or experience 🙂
Thanks 👍 Yes pretty much. I've just messed about and fixed stuff for years, although I did so a bit of a course on basic electronics and computers when leaving school, but I got bored and left as I knew more than the guys that were doing the teaching 😂😂
Good fix. Need to be mindful of those USB meters - I bought one of those recently, they have some odd quirks. You cannot power it from a standard usb port and output on a USB C - it doesn't work. Also the USB C ports have the wrong notation on them - the input and output legends are reversed. Not sure if your powerback was pushing an amp back into the charger or not, but mine refuses to work unless to plug input power to the output port and vice-versa. It's junk in other words - it also disagrees with another tester I've had for some years on VA/W, but I guess I need to set a proper test rig up to see which of them is more accurate...
@@BuyitFixit Oddly, I just tried it again using USB A to power it and using its USB C to charge a 'phone. I had it downstream of another USB meter so that I could see what was going on. It did charge the 'phone, but showed no current being drawn, although the meter inline with it showed it was passing 300mA and the 'phone acknowledged that it was being charged (phone was almost fully charged). Woeful bit of kit unfortunately.
Strange, I've not really used it with the USB C connection much. Although I have used it with the A and a USB A-C lead and it seems so work fine. I wonder if yours could be a defective unit?
Another one for the books ........ Yeah a cap book would be handy for you , I need one to instead of robbing them off of boards ..... I bought a empty book and ordered assortment kits of resistors and it still isn't full ..... Bigger sizes mean more money ....... Take Care Mon Ami..
I have also heard that after the vinegar has neutralized the alkaline corrosion you should use IPA to clean it so that the vinegar doesn’t turn into a source of corrosion. Vinegar is an acid and it is used to neutralize the alkaline which is a base. Both acids and bases can be corrosive but also can be used to cancel each other out.
@@rangercv4263 Correct, I normally use IPA afterwards. I was teaching my 11yr old daughter a few days ago how to do the exact same thing as she had an old furby that the batteries had all corroded. After removing the corroded batteries I got her to use vinegar and a cotton bud to neutralise all of the alkaline and then we cleaned it all up with some IPA. It still didnt work as the corrosion had caused one of the wires to come off inside so I sorted that bit for her 🙂
Had a baseus 20ah powerbank with 65w pd.. I bought it for the 65w pd.. the pouch cell failed on those.. left it to charge and came back to see those cells uncomfortably warm.. disassembled on the spot.. those cell were even warmer when i touched them directly... i got the controller and the bms (3 cells were wired in series) whats wierd is power bank is labelled as 20000mah, but the cells used were 3x10000mah in series, resulting 10000mah Didn't notice the written power capacity tho
I'm not a great fan of pouch cells. I think 18650's are safer (although I could be totally wrong!). Yes it's not unlike companies to "mislabel" or exaggerate specifications on devices, especially devices that come from China.
@BuyitFixit yeah, I'm not a fan of pouch cells too.. I'm planning to rebuild the power bank using 18650 cells to get a proper 20ah 3s power bank using the controller, i might change the bms tho as i think the bms is a poorly built one that allows slight overcharge of the cell.. haven't started yet because a proper 18650 cell is expensive in my country
I've noticed that as soon as you get at 90% battery on the phone, it ditches the QC supply of 9V, and switches to 5V. So it's probably not the power pack, but the phone itself who's limiting the current.
Today I checked the booster pack ("Baseus Car Jump Starter 12000mah 1000A Power Bank Portable Car Battery Booster 12V Auto External Battery Charger" ali search string) and the rain leaked on it, no lights and rusty connectors :( I need to clean and repair it.
watch your eyes for the UV - fortunately I was wearing a tin foil hat in case the video was reading my mind, so I was ok, but I did burn my fingers a bit on the images of the hot air rework station.
So let me get this right........ you did fix some wires on your wire less charger, and also you need a wire to charge it? I start to think that you have a loose wire somewhere else too. 🤭
Geeez dude. I’m gonna skip watching vids where you handle anything with a built in battery soon. You must stop poking about and or scraping with metal. You’ve clearly not got respect for these and the fact that they can leave your face with vaporized tracks, metal and what’s worse. You use plastic tools/spudgers to remove residue etc. yes I know it’s just a few volts but the short circuit current delivered from these cells is massive. If you disconnect the cell/battery you are of course good to poke all you want with your probe or screw driver. But you doing that with the cell connected makes me instinctively want to put my safety squints on. I guess an explosion needs to happen before you start respecting them.
I have a Bluetooth speaker I got as a present from my father and it charges so so so so slow at like 0.014 MA. How do I send in a item for you to make a video on? I took it apart and couldn't figure out what was the issue.

1 question
While working such a small PCB what? temperature and air you set on SMD machine.
I normally use 450c and turn the air speed down. I'm no expert though 🙂
Unscrupulous eBay listing if you ask me,it's always water damage 😂. well done 👍
Thanks 👍

What are you using for a microscope and what kind of flux are you using?
Flux is in the video description along with some of the other tools I use. The microscope is a trinocular with a 48mp camera.
I admit I did not think to look there. Now that I have, when I click on it, Amazon says it’s not a functioning page.
Strange, I'll have a look at that.
