    Multiple USB-C charger brick are there any for sale or do you have to build your own

    I have some what Google it but have not found anything so far

    I am looking for more than 2 USB-C out jacks ideally I looking for 4 or more

    Also if I am making my own switching power supply brick what type of USB-C device board do I use for this purpose that can you negotiate different voltages like—> [ 5 volts/9 volts/12 volts/15 volts/20 volts ]

    Does anyone know a website that I can look at some


    Thank

    usb-c is just a connector standard,
    what your looking for is power delivery or PD3.0

      I want to supply the USB output jack so that it power anything from 5 volts and is 20 but I want it to negotiate different voltages like—> [ 5 volts/9 volts/12 volts/15 volts/20 volts ]to do it automatically

      Something like this but with more ports than this one

        yes, that's called PD3.0

        dont get PD2.0 because it's for phones and only goes upto 9v

              I posted the website link earlier there several diagrams for this device

              I tried twice to upload the diagram but it does not want to come out clear to be able to correctly read it but you can see at the website link that I posted earlier

                Not true, Power Delivery is 100W regardless of the version number, it's just there's no point building and selling chargers and cables for phones to that spec, which is why you don't tend to see them.
                There's better detection, reporting and interaction between device and charger with PD3.

                sam_sam_sam. there's a reason you don't find 400W universal USB chargers.

                  What I am after is a multiple usb c output jack that can negotiate different voltages like—> [ 5 volts/9 volts/12 volts/15 volts/20 volts ]

                  I would like not have a bunch of wall chargers all over the place
                  But I am having a hard time finding what I am looking for

                  This was the reason for looking into building one myself but finding the parts might become challenging at best

                  Unless someone knows where I can find one

                    i think there are chinese modules with 2 on them.
                    i seem to remember someone on utube reviewing it - it had a buck/boost so you can run it in a car too.

                      If you locate a 100W unit Type C adapter, you will be able to have the range you have listed.

                      These are USB Power delivery contracts. The vendor of the adapter defines the contracts (voltage & amps) for each pair.

                      Then on your mating widget, you are required to negotiate over the CC1 / CC2 lines using biphase communications to 'dial up' the contract of interest.

                      There are single chip solutions to allow for your end widget to select the contracts from ST / Cypress and most likely others.

                      Be aware that the adapter will share the power ratings across their ports. So this means if you want 100W (20V @ 5A) on a single port, then the other onboard ports will NOT be able to support the same output. Often it is a wimpier output due to the above contract.

                      Respectively, if you wanted 4 * 100W of power for whatever reason, then the adapter box must support 400W of conversion to permit any contract on any of the USB PD3.0 port.

                      Not aware of such a design yet. We have been tossing this around for a while but openly the market is after low cost solutions and solid products cannot be built for the 'amazon' style of pricing. Once you review the negative posts for each such adapter, the real world reviews will surface.

                      Also, very important, check for UL / CSA approvals on the adapters - extremely rare if even true. It is illegal to sell such items due to safety reasons yet Amazon is flooded with such listings.

                      Not our cup of tea for our product designs. The liability of poorly designed products is just too high and are fire hazards.

                      We are still open to build such a box but as noted, the demand appears to be little to none. A few vendors attempted some slim jim adapters with xx watts and failed miserably on kickstarter and indiegogo.

                            This made me search for this device a little bit different in the aspect of looking for USB charging controller board

                            ( tear downs videos on YouTube )

                            that are being used and I found a model ( 45 watt charger ) that has a separate board for the USB C jack and from what I can see while this person is doing this review I was able to get a pretty good look at this module board ( and from what I could see it only has two connections ) and if this is the case then all I would have to do is buy several of and just power them from one power supply

                            Thank you for pointing in a slightly different direction for what I was looking for

                            The way I going to use this USB C charger setup is with trigger boards at different voltage at the same time with maybe a current of less than an amp to maybe as low as 200 milliamperes on each trigger board but keep the current below a laptop charger switching power supply

                            Also while I was looking I also ran across the laptop chargers that are USB C based and can negotiate different voltage as well but you only have one single power output but I also have a use for this as well

                            Also while I was at it I have found a board that would do what I would like to do however they are back order undetermined availability date so if this company gets them back in stock I will probably buy some and also do it that way as well

                            I have a Anker USB-PD C charger that I took apart and it has three connections and one of connections goes to multiple ic pin device that ( that is on the main power supply board) I have not so far looked up but this not going to work for how I want to use it

                            But I going to put it in another case and make it a desktop USB C charger because I really can not stand the wall based USB Charging units

                            So again thank you for nudge me in a slightly different direction and I ran into some different solutions for this project problems

                              Hello everyone,
                              I am new into this, sorry to post it here. I want to make this as a pet hobby project, as this mac is not urgent.

                              I have (Macbook Pro 13inch 2017mid) A1706 820-00923-A

                              My mac had liquid damage a long time ago, the connector from J8500 is damaged on pin 46 (PP5V_S0_ALSCAM_F), I guess the LCD/display panel is in short circuit, as I saw the connector from the LCD burned as well.

                              And the resistor L4004 is literally burned.

                              From what I see from the schematics, it does not affect any other rails, only the connection to the display...

                              - 12 volts line is shorted
                              - DA9065 was fried, F7003 also => Replaced both of them, short is gone on 12 volts line, no dead short anywhere else.
                              - By the way, nothing change. No signal, no power, no beep.

                              My T14's (NM-C801) main USBC input keeps failing every few months. Initially, it worked fine for several years. The symptom is that once powered from the main USBC port using a 65W power brick, after some time (minutes, hours) charging will fail completely. Powering from the secondary (docking) USBC input still works. This laptop is basically always plugged in. The first time it happened, it took me a long time to find that the FPF2281 over-voltage IC for that USBC input was at fault. When the issue occurs, it will continuously reset power delivery negotiations with the power brick -- according...

                              Hello,

                              Dell Latitude 5420 P137G
                              Board: LA-K491P REV A01

                              I have received this laptop which was described as "does not power on or accept charge." Battery shows no sign of charging when charger is plugged in, nor does the board show any signs of life when battery is unplugged and charger is plugged in. No light from the LED at all or any other indications of activity.

                              Board seems to have no shorts, all power rails are fine and show high resistance.

                              When charger is plugged in, voltage is present in 3.3V rail but absent in others....

                              I have this 10 amp 0 to 30 volt switching power supply that decided to have a 630 milliamperes draw on it at 0 volts

                              I open it up to find non brands name capacitors in it

                              I am not sure how this switching power supply is set up

                              Could someone please explain how this power supply works

                              Here is the capacitor ESR results
