You have the idea down, I have been using this cable and this adapter to power the deskmini as they combine the trigger and the barrel jack in one. The power bank I have been using only has one type-c port so cannot charge itself and power the PC at the same time. I have seen some power banks that support passthrough (I believe the baseus blade does) but sometimes charging the device causes it to renegotiate the PD, which would cause the PC to shutdown. This is also a problem with some multi-port type-c chargers (I found out the hard way). If anyone else wants to replicate this I would love to see their results, but I want people to recognise the risks. I am powering the PC with an incorrect (albeit only very slightly incorrect) voltage and from a source it wasn't designed for (batteries). I am willing to accept this risk and have had no issues thus far but will keep you updated if anything changes!

Hi! I am currently typing this on the PC powered by USB PD! The 19V regulator caused more problems than it fixed as it struggled to quickly adapt to an increased load, which triggered over current protection and required everything to be unplugged and replugged. Instead I am running it on 20V directly from a PD trigger. So far the battery life is around 4-5 hours of normal use. When being benchmarked it uses around 50W which means it would last just under 2 hours. Overally very happy with the system, any questions feel free to ask!

So it has been a while and the project has made a lot of progress. I have built the PC and have ordered parts to make a PD 19V power supply. The build is as follows: CPU: Ryzen 5 5600G Ram: G.SKILL Ripjaws 2x8GB Cooler: Noctua NH-L9A chromax.black WiFi: AX210 All inside the Asrock DeskMini X300 The system is set to run in 35W mode in the bios which should keep the system well below the 100W limit of USB PD. To get 19V from a USB PD power supply I will use a 20V PD Trigger, 9-36V to 19V regulator, and a standard 5.5x2.5 barrel jack As soon as the part arrive for the regulator I will be soldering it together and testing it

This will be possible but I just need some clarification. My understanding is that you are wanting to have a fixed cable like it is now but with type connector instead of a type A connector on the end, is that correct?

I have made a PWM controller from an Arduino nano, if you still wanted help with creating a PWM control circuit I would be more than happy to help. Just PM me!

This is very similar to the Asrock Deskmini, which I am planning to get and use a Ryzen 5 4650G inside. I like the idea of a ready made solution but as it compromises on upgradeability I don't think I will go for it.

I have been using a type C 20V trigger to lenovo slim tip connector to charge my laptop for some time now, I will use a similar cable from here to do the same thing for the PC.

I have found this: NUCLEUS by OTG Technologies and E EGOWAY

I am in the process of parting out an small PC that I can power by a USB-C PD battey bank. Current plan is to use an Asrock deskmini as it is small and runs on 19V DC which means it SHOULD be fine on 20V but this is something I need to double check. I will need to source: - Parts for the Deskmini - A large enough battery bank that can do 100W of PD power - A 20V USB C to DC barrel jack cable Questions people have asked me: Q: Why? A: Because I haven't seen it done and I want an alternative to a laptop Q: Why not just get x laptop? A: Because laptops have basically no upgrade paths or repairability and I want to see if I can Q: Will it not be a bit impractical? A: Most likely

You want to look for a JST-SH 8Pin Socket 1mm Surface Mount connector then. It is important it looks like this:

The connector looks like a JST connector, but you will need to know the pin spacing as it varies

Apple has some extra chips in the camera connector, there are some adapters available on aliexpress but they have mixed results

Love the idea,I've though of doing something like this in the past but never got around to it. One thing I have been doing is converting a laptop to work as a keyboard, mouse, and monitor, like the lapdock. I found this video very useful and think you may too as it would allow you to use a laptop keyboard which could save you even more space:

Been watching this build for ages now, it looks amazing and I love every update! Keep up the phenomenal work!

Here are all the pictures I have of the disassembled card
