Ordering random chips from China, they have different markings and you go and stick it in a battery protection circuit? You're a braver man than I am! :D Glad you didn't explode.
I didn't realise that the markings were different as it was not listed as a different version, and even the photo showed the part that I needed. It was only after fitting it that I noticed the T suffix. Normally a different part would have a totally different number not just adding a T at the end. I've used parts before where the number hasn't been exactly the same but the part function is the same. Yes, I too am glad I didn't explode 😂😂😂😂👍
Injoinic actually make quite good powerbank and usb management ICs they even have English datasheets for a good deal of them. Still a terrible idea to mix and match though xD
Yes, it was probably not economical to repair, but it's a good feeling when you repair something and we'll have another happy "repair cafe" customer! Have a great new year👍
Yes, it is satisfying when you eventually get something working 👍I'm not sure if you saw some of my other work such as the recent AVerMedia device I repaired which was a bit more out of the ordinary, or the FLIR thermal camera, or the solar inverter I repaired, then in a subsequent video had to reverse engineer the service password algorithm and write my own tool to get into it 😂😂👍
Great video! I find if the battery voltage varies much between the batteries the device can refuse to start up. I just but a suitable battery charger across the low one for a couple of minutes to evenn them out a bit.
Yes, cell balancing. I had to do that with the NOCO boost pack I looked at. Unfortunately that doesn't have cell balancing at all, and I found that the cells eventually go out of sync after a while and cause them to stop charging when any of the cells reaches 4.2V so that's probably why there was so many failed ones for sale on eBay.
With all of the problems in the world, I think there are bigger thing's to worry about then people's use ov spelling and grammatical being correctly 😂😂😂Have a great new year!

Amazing work on the diagnostics as always Mick. Great fix. Love watching your thought process how you work through the board. Happy new year to yourself and family
congratulations with the success after all. it's the fun of repairing as buying the ICs and the repair time cost more than a new one. My heatplate for frying pieces of meat on the table went into its box in working condition and when I wanted to use it on Christmas it didn't work (no flash or noise or breaker tripped, just nothing). I measured the heating coil and it has a resistance of 35 Ohm so it's not broken somewhere. In the side of the pan there's a small power box with a dial for the temperature that you can pull out. It has a thick metal pin connected to the bimetallic strip in the powerbox and the other end sticking deep into the pan so it can measure the temperature. I opened it up. The bimetallic strip works fine and connects and disconnects when I turn the dial from it's lowest position to a higher setting. I also measured if the positive prong of the Euro Plug conducts through to the positive out and it does when the bimetallic strip is pressing to the contact. There's a small incandescent lamp and does not light, could it be used as a fuse ? (it seems to be in parallel though) . I now suspect there's a fuse inside the heatshrink sleeving over the neutral wire as there's no conductivity between the negative prong of the Euro plug and the female neutral socket going to the plate. I don't find it easy to cut the heatshrink off and also I'm not sure if what I see is thick enough to hold a fuse under the heat shrink. I'm contemplating on going to the local Repair Cafe (I'm in The Netherlands) but maybe you have an idea ? I can show pictures if you like.
It may have a thermal fuse somewhere. The lamp in parallel with the thermostat is usually so it lights up when the device is at the correct temperature.
@@BuyitFixit yea I was thinking the same. I'm suspecting it's somewhere in the neutral lead as I don't get continuity from the plug's pole to the neutral out.
Thanks 👍Happy new year too! I just ordered them on Aliexpress. It's quite good for chips, although I've had counterfeit chips in the past, and the shipping time sometimes is quite long.
Nice! Did you replace the C5 capacitor with a new one or did you use the old one? At 12:40 it looks like the C5 is cracked, just wondering if that might have been the problem.
I doubt it, all of the regulation seems to be done internally within the IC. You can only set things like the current limiting with resistors. A solution might be to get an adjustable boost converter board from ebay which you could plug into the power bank and boost it up to the 6v or whatever you require 🙂
@@BuyitFixit thank you dear for your answer,I have bought the upbooster from 5 to 6 volts but it gives the hell of the noise.Recently I have spot a power bank from Ali express that besides the 5 volts it has a regulated adjustable output for voltage and current.Then I realized that may be possible through some resistors in tha power intelligent chip.
@@BuyitFixit yep just binge watched allmost all your videos now… ya very talented pal 👌 im looking to get into stuff like this got Most Gear but Zero IdeaZ lol thanks for the info on your camera 👍 look forward to your future videos.
Question, to the end of the video. This UV light. That is for epoxy stuff right.? What is the best way to get RID of this epoxy stuff from the motherboard. I have an old smart phone and they used epoxy on the SMD switch which i had to replace. Get this stuff off is a nightmare. I ended up filing down the epoxy. Cant go to far as there is a resistor or cap under it.
Yes the UV light can be used for epoxy but I got it to cure solder mask. Have you tried heating the epoxy with a rework station then picking it away? I've had some success doing that but it depends on the epoxy.
I cant use heat again this is where the switch was. I had to heat the switch apart to get it off the board and the resin remained solid. ughhh.@@BuyitFixit
Hi. I wonder why did you go with 509T and the hassle of adjusting the pcb. You had both 509 and 509T ICs on hand so probably some advantages of 509T over 509? Thanks for the video and happy New Year!
I order a 509 but the seller sent the wrong chip. They sent the 509T I didn't realise there was a difference. When I noticed it was different I first thought about adjusting the original circuit as I would have to wait another month to order the new part so I did attempt that, but the realised it was more of a pain than waiting another month for the new chip. The video is split over 3 months, so I didn't have both chips to hand at the time. Hope that clarifies it🙂 Happy new year to you too 👍
I really really wished you would mention what ohms through each resistor. Resistor 010 and so on. I get the 0 version should be max 0.7ohms according to your Mmeter. I am still learning and it is somewhat hard to follow when i have no values to work with. Other than that friend this is great stuff.
You lost 2 times your footage😱😱? Nooooooo.. It smells like a conspirancy 😳😳. Ohh man, yes the letters at the parts are cursed🧟♀️🧟♀️ Good work and repair 👍👍👍 Have a good time and Happy NEW Year i wish @all.
Thanks, yes because it was over a couple of months I formatted the camera card as I thought I had all of the footage. That's the problem when using multiple cameras and especially over a couple of month. Hope that you have a great new year too!👍
I love how you think "out of the box" Keep it up. We all learn something new every video.
Thanks Fred 👍

Most people who work with electronics are a bunch of pu*****. So i don't doubt you.
There are many chips now which differs in function with a different suffix at the end, i encounter these regularly
Injoinic actually make quite good powerbank and usb management ICs they even have English datasheets for a good deal of them. Still a terrible idea to mix and match though xD
Most people would just throw things like this away. Great seeing them being repaired and saved from landfill 👍

It’s crazy how satisfying it is to find the faulty component on a PCB. Well done!! You make most of the other repair channels look remedial.
Yes, it is satisfying when you eventually get something working 👍I'm not sure if you saw some of my other work such as the recent AVerMedia device I repaired which was a bit more out of the ordinary, or the FLIR thermal camera, or the solar inverter I repaired, then in a subsequent video had to reverse engineer the service password algorithm and write my own tool to get into it 😂😂👍
Just amazing to watch you work. Thanks for posting the very informative videos

@@BuyitFixit Thanks Mick, you too!
Separate cells, that's nice for a change. Seems I always keep finding Li-Po's inside, really hate those.
Yes, I'm not a fan on pouch type cells either.
I have a power bank almost exactly like this but 2 cells instead of 3 on my bench now with exactly the same symptoms ! Lol !....cheers.
Nice! Well hopefully you've got some measurements and stuff to work from now which might make it easier to repair 🙂
Well done
Thanks 👍
Nice little fix there
Thanks 👍
Obviously did the chip twice, just for me so I could watch the solder :-) Hope you have a great Year.
Thanks 👍hope you have a great year too 🙂
Those three cells would've went in my parts bin and the board on the scrap pile. You are braver than I. Glad you got it working
Thanks 👍
Mick you have patience of a saint, I think most people including me would of threw in the bin…
Nice work and a great fix yet again 10/10 😊
Thanks Gary 👍hopefully your Nintendo switch is still working well 🙂

Sorry about that, I did a 4 part tutorial on how to test different things with a meter on the channel last year, which may he helpful.
