Thanks for the detailed teardown! It would be nice if you could also look at the USB connector. Dell is doing something proprietary with their chargers and others have found that replacing the USB connector on the end does not let it charge correctly. Perhaps you could see if there is a proprietary chip on the USB-C side that could be taken off and soldered to the new USB-C cable.

I currently have 3 of these units where the cable from the charger to the laptop is damaged, and it is this cable that I need to replace. In order to open this without damaging the outer casing with a "Dremel" tool, slide the blade of a screwdriver (or a "Stanley" knife blade between the end cap at each end of the unit and the body of the outer casing and ease all the way round to loosen. Do this at both ends and then ease the end caps out. At the mains end, there is part of the heat sink which you can then use to lever out/push out the transformer. The unit will then slide out of the casing relatively easily and will not be damaged. Now all I need to find is a replacement cable with a USB type C on the end of it. Thank you for the insight offered on what's inside the unit, it's helped me figure out how to open it without damaging the casing.

I find that gently squeezing the end that you're trying to open with a vice opens the gap up so its much easier to get the blade in and pop open the case. I have three dead ones that I'm trying to fix. Not the most reliable power supply.

@@BravoMx Would it not be as simple as cutting off the old end, soldering the wires together and heat shrink it together, that way you don't need to open the charger at all? I did it with a non Dell cable with an E Marker chip off Amazon and it would not power neg the current so it would not go over 5volts. I put this down to not having the dell chip.

This is terrific! Thank you for your detailed teardown and analysis. This is the kind of KZread material that should rise to the top.

I really enjoy your videos, your detailed explanation of the chips and how frecuently upload new vídeos. It’s difficult to learn about chargers but you make it easy. I would like to see a video about making your own gan charcher, making like an open source charger that you could download the pcb and send it to print. It also could be modular, depending of what are your charghing needs make it bigger or smoller and print the case with a 3d printer. That would be awesome. Love your videos carry on :)

Today I grabbed my ac adapter from the cable(this one that connects to the laptop). The adapter seems to work but I am afraid if I provoked any damage on the cable connection to the adapter. Is this point (the connection) strong enough or not ?

Any ideas on how they implement 6.5 amp of the usb protocol chip is standard ?

very helpful. thanks

do you have the circuit diagram of this charger

How can they use 6.5A on the USB connector who is only rated for up to 5 amps

Why a earthing line is given in dell ac adapter?

Excellent....I have Dell 24111 Power Adapter 12V 2A and before it used to come alive after 15 minutes but now NO luck - any advise and using a sawblade to cut it open is the only way to see inside? But, there are gaps of 2 mm all around where the top and bottom halves join??? How far are you from Quebec, Canada?

Very nice

Do you know which chip is responsible for the DRM. Third party usb c can only charge up to 65w on my 9575, and I was hoping I could hack my laptop/charger somehow using the DRM chip😊

Great video, thanks! How can they use 5A output fuse if output current is rated at 6.5A?

@ChargerLAB

Yes, the suitable output fuse should be 6.5A, but actually, the fusing current will be higher than rated current. So...

I hate companies making those things not modular and undisposable. My cat started to chew usb-c cable and instead of changing cable I then will need to replace whole expensive unit...

Hi @ChargerLAB, just wondering if you can help. I am trying to repair the USB C connector on this charger and just wondering where the red, blue, black and white cables go to. The black and white cables are thick and must be gnd (black) and VBUS+ (white) but the red and blue I am not sure...

Yup, I was wondering the same thing. I have to change my USB-C plug out on the Dell adapter and noticed the plug had a chip and some components in it. But mine is just the three wire version, Black, White and Blue. I take it that the Blue wire is a communications wire back to the charger.

@bigbrobropro2152 : So what kind of a charger are you trying to use. If it is a dell intelligent charger then I doubt that it will work as it sees no communications to it so it's output stays at zero volts. The usb-c plug of the charger also has some little circuit in it to which I am not sure what it is for. Just use a switching power supply instead with an output no higher then 24 vdc as you can adjust them down to almost 20 vdc.

Oh my! So, is there a way to disassemble the adapter without tearing it apart? I have damaged cable (not replaceable part) near the block and wondered if I can just cut cable short, open block and re-solder cable back to circuit board. So does Dell make them unopenable?

Hey, i'm traveling from the past to say if your charger is failing intermittently, the problem is the big electrolytic capacitor.

Where can I find just the USB-C cable part that goes from the brick to the laptop? I broke mine when I tripped over the cable. It looks like you can just open the power brick from one side and replace just the USB-C cable. Could I grab one from a 65W or 90W brick? Anyone got a link? OP?

Is absurd that they use bad capacitors even in theese very expensive type-c models. My standard 130w Dell charger become faulty because of the bad capacitors with only 5 years of use, sure theese ones will have the same fate.
