Heh. That's hardly something to fault it for, given their meant for phones / phablets. Want to full-juice a running laptop, wire up an inverter.

So I ordered this and just received it today. Was I suppose to receive only the 1 usbc to usbc or was there supposed to be the USB to usbc? Package was sealed and wasn’t sure the box was misprinted as it does say 2 different cables.

Related, but I received one in the mail the other day and finally got around to testing it out. 20.2v coming out of a very standard common polarity barrel jack, 2.1x5.5mm. Inside the black box is a usb pd trigger which has a button to adjust the voltage. These are just shipped at 20v which is perfect for my use, and I didn't mind paying a couple of bucks more for something in an enclosure.
I have a portable battery pack in a knock off pelican case that has a solar charge controller inside. I'll just install a robust 2.1x5.5mm panel mount female jack with weather resistant cap and connect to solar inlet. Charge via reasonably small panel, my macbook charger at home, or from a USB PD car charger thanks to this little cable (which must have 20v output option, two of my three pd car chargers do not - doh). $7.75 on ebay/ali and even amazon if you'd like to get it in a few days vs a month. 'USB PD TRIGGER' + 20v, or DELL, or 2.1x5.5 should produce. Or spend less than half that for the board alone.
I predict we'll all soon be blessed by a ton of PD tinker boards and diy lantern / boombox / general pack builders will have a lot to play with. The wall warts and car chargers are now extremely affordable and having a reliable way of negotiating voltage from one is a game changer for me.

FWIW, just charged my 90ah lifepo4 pack up to 100% using the above dongle thing. I set my Victron charge controller to a max of 4a charge current and it resulted in 68w of power being delivered to the battery using a macbook 87w usb c charger. I used a medium grade 6.6ft long USB C cord which I just learned has a max rating of 20v 3a, which explains why it was getting warm. The gizmo itself was cool to the touch. I'd get a shorter and thicker USB C cable for long term purposes, but I won't need to with the below...
So this will definitely work for charging my portable lifepo4 32ah 12v packs-output 20v and step down via charge controller or buck module. I once again found myself looking for a powerful USB PD car charger and I don't really want the bulk of a cigarette lighter style one. So here's what I just ordered, figured it might be useful for people wanting to do the same. This evaded all my searching for days, weeks. 20v, 4.5a out. Having a large brick makes me feel more comfortable with pulling say 60w from it continuously, versus doing the same with a cig lighter style compact unit. Of course it's totally effed if I damage the usb C bit.. but I plan to lop off the cig plug, wire to my fuse panel, and tuck the brick out of sight.

Nice find! I've also been searching weeks for something like that. The only piece left of the puzzle for me is a USB-C flush panel mount (to fit a ciggie hole). Do you know of one?
I've only been able to find this: https://www.usbgear.com/CG-U3CMCF20-PM.html

Is this what you are looking for?

Not exactly. That has a built-in charger (with low output) and not a fan of the voltage display. Just looking for a simple panel-mounted usb-c plug to hook up to the charger that Hour posted.
Though I would happily take a charger in that form factor, as long as it was high output!

Yeah, me too. I guess I could extend the longevity of the USB C end of this charger (which I just received today, amazing next day delivery) if I found a female to panel mount. That'd mean the charger's plug wouldn't get disconnected really ever, but I do wonder about voltage drop. Highly doubt that'd be a problem using a panel mount extension like was posted - for laptops and stuff. My USB-C to 2.1x5.5 PD trigger thinger might stop doing its thing if the voltage goes too low.
I can't find any USB-C panel mount female to female offerings anywhere. They make female to female couplers which would allow the panel mount thing you posted to work with the charger I posted, but that's one more dinky Chinese item to bank on. Ad states 3A max :| . In fact, the 20" panel mount extension you posted only states '5V3A' so I have no idea how to interpret that and scale for 20v charging.

5V@3A(5*3)=15W.. 15W@20V(15/20)=0.75A.. DC cabling meets amperage limits before voltage limits, usb-c's higher volts allows more wattage with same or less amps.
USB-C Socket Durability is an order of magnitude better than USB-A if built to spec.

So if it handles 3a @ 5v, does that mean it handles 3a at 20v? Or more? Or less? I'm thinking both carbon60 and I are wanting to run in excess of 60w / 20v@3a to make use of the large power supply capable of 20v @ 4.5a.
I'd put more faith in the 20" panel mount extension posted being to spec than a $5 thing from eBay, but I'm mostly used to reading stories of USB C to USB C cables - never looked in to couplers.

yeah it should handle 3A at 20v (60W)
