    Great video! Very informative and helpful for someone like me, who doesn’t yet have a full grasp on different power protocols and delivery methods. Will be keeping these things in mind when I’m in the market for a new power bank and new USB cables.

      Glad it was helpful. The QC and PD situation is quite complex and confusing unless you study how it works.

      Useful feature that you find with some power banks. Not an advertised feature.

    I'd love to see a video about PPS and higher current on voltages under 20v!

    • @Elecami
      @Elecami  Рік тому +1

      I could have a go at some point. I do have one adapter that can do PPS, but it is really annoying to use. it just has up and down buttons. And with 20mV steps, it takes a very long time to change the voltage by much.
      I also recently ordered some PD 3.1 decoy boards. Those can do the 28V 5A 140W Output.

      @@nicoful86 You can use the PD Trigger / Decoy at 9V, 12V, 15V as well. But for high current loads, it is better to use the 20V with a buck converter, to get more power capability and to absorb current draw spikes that could cause the USB-C Power Supply to shut down on over current.

    Thanks for the idea of PD + step buck converter. I will try it for a small laptop that works at 9.5V but not at 9V.

    • @Elecami
      @Elecami  Рік тому

      Interesting that is is picky about the voltage.
      Problem could be that the USB-C 9V is very sensitive to current spikes. It will shut off if high current is drawn even for a very short time.
      Connect to laptop then connect to the USB-C might help.
      Or use a buck converter as you say. That provides a good buffer between the device and the USB-C power supply.

      @@Elecami I tried it last night and it worked flawlessly with a 12V trigger + step down ☺
      Previously I used an adjustable trigger set to 9.5V which worked with a PD wall charger but not with my PD powerbank.
      The bank would get the voltage but return to 5V after 3 seconds. Could be the current draw, but it returned to 5V even when not plugging in the laptop.
      Perhaps an incompatibility in the protocol/timing of signals with the power bank. At 12V the bank is rock solid.
      At 9V direct from the trigger the laptop would not turn on, even from the wall charger.
      Thanks again for the idea.

      @@yomboprime The adjustable one is probably Quick Charge 3 protocol. Not supported by all chargers.

      @@Elecami No, really it is PD 3.0 and says it is using that protocol at the beginning in the 7-segment displays.
      It is possible though that it is using QC3.0 underneath in the adjustable mode, who knows. There must be some incompatibility with the powerbank, but I have no clue or way to solve it.
      Anyways I am happy because I can now use the big 30Ah bank with the laptop, thanks to you.

    I have a realme charger which supports 5v 6 amps but only provides 10w when something other than phone is connected can you suggest a pd trigger board for this

    • @Elecami
      @Elecami  Рік тому

      Depends what the protocol is. What phone is it that can draw 6A. Maybe Quick Charge? Or might be another protocol specific to a manufacturer.

    Hi, thank you for your video. Do you know if any newer trigger boards are on the market which you can use like Tha black and yellow one you showed, which could work as a sort of power supply? I m looking for something that will kind of work like a bench top powersupply when used with a pd power supply.

    • @Elecami
      @Elecami  Рік тому

      The one shown at 9:22?
      I have not looked for any more of these recently. If you take a look on AliExpress you might find some.
      Have a look here for many options. rdtech.aliexpress.com/store/923042
      You can use a 20V PD Trigger board to get the power to input to one of the regulated power supply Modules.

    There are a variety of modules in this video. Can you share the ink to buy them? In India? It is hard to find, also expensive.

    • @Elecami
      @Elecami  2 роки тому

      Search for USB-C PD Trigger. Or USB-C PD Decoy.
      There are a lot of options on eBay and AliExpress.
