#powerdelivery

Props to Southwest Airlines for having the forethought to provide 60W USB-C directly on their newer 737 flights.

It's much easier to retrofit planes with higher power USB & I don't rly need 3-prong AC most of the time if I have USB-C Power Delivery for my laptop & phone.

@mrmasterkeyboard np.

  • I thought the glare was excessive due to the lights, but then again I'm not gonna complain more about it. Noone expects you to have a fancy mattebox with turntable to make some professional product photo.

Also even if people don't have a donor to transplant a screen assembly from or don't feel comfortable fiddling with eDP cables they could just remove the screen and have a compact AiO Desktop.

  • If it has like a "full function" #USBc port with #PowerDelivery than this can result in a sleek desktop that also looks good and doesn't require much space. Ideal if the battery is busted and a replacement isn't worth it! I've seen those in like #RepairShops where they basically setup some #MacbookPro that way as a DFU machine to reflash / reinstall other #Macs.

I think it's a necessity that we as #TechLiterates propagate the need to #UseLonger and the #RightToRepair as essential, given that #tech inherently is expensive in terms of #resources and that avoiding #eWaste and #Upcycling is an act of #EnvoirmentalProtection.

  • Tho make shure to safely remove any "#DangerPillow|s" and handing it over to the relevant #recycling provider(s)...

If I had the necessary €€€€€ I'd literally start my own "#upcycling" #business, even employ some folks collecting all the #surplus'd #Windows10 machines and just cleaning, wiping, repasting, fixing and selling them as cheap #used #PC|s for those that kinda need something to do their casual "#office", #LightGaming and #MediaConsumption.

  • I mean people are surprised how zippy even old hardware can be with just few tweaks (more RAM, a fresh SSD, cleaning it of dust bunnies and repasting the cooler with some quality (longlife #ThermalPaste, like #ArcticMX4) "#ThermalGrease" (that costs like €1/g in a 20g syringe and a #RepairShop can easily go through one in a shift)...
MastodonNerdNextDoor :Blobhaj: (@mrmasterkeyboard@mastodon.social)@kkarhan@infosec.space Thank you for the comment! In person the screen is great for me, just unfortunate camera lighting angles. :p Ubuntu is something that I thought would suit this laptop, I wasn't wrong, it's blazing fast. The startup time is only more evidence to that. I would also get something like this as well if my budget was £100 and if I couldn't fix things. #Repair and #Reuse needs to be the default, I love repairing machines. Not all broken screens and dented machines are junk, people!!!

Gibt es hier Leute, die sich mit Problemen bei #USB PD auskennen? 🔌

Ein #Smartphone wird an einem 65W USB-C-PD-Netzteil (9V/3A) problemlos mit per Multimeter gemessenen konstanten 3A bei 9V geladen - soweit gut, ist das Maximum des Gerätes.

Selbes Gerät und selbes Kabel an einer 100W #Powerbank (ebenfalls 9V/3A möglich): schaltet korrekt auf 9V hoch, aber die Stromstärke kommt nicht auf über ~1,1A. Auch an einer zweiten kleineren Powerbank (9V/2A) bekomme ich im Ergebnis maximal ziemlich genau 10W bei 9V raus 🤔 Powerbanks waren natürlich voll und das Smartphone auf einem Ladestand, dass es das Maximum von 27W aufnehmen könnte.

Kann man irgendwie herausfinden, woran es hängt? Oder ist das einfach eine zufällige Inkompatibilität? Die Powerbanks liefern sonst auch deutlich mehr als 10W, wenn auch bei höheren Spannungen.

@danderson personally, I prefer to go with either 48V, 20V, 12V or 5V in DC application depending on what's convenient.

The 7,9x5,5mm ThinkPad barrel jack can do up to 11,5A originally, giving you 230W at the plug end.

  • Pretty shure they did standardize it for 16A given all classic thinkPads used it except the very old ones.

That being said #USB-C-#PowerDelivery rocks and there are off-the-shelf ICs and boards to negotiate a ceetain voltage/amperage for any needs.

  • Second best is #PoE++ 802.3bt Type 4 which is ~ 60V and gets you 100W and at least 87W at the device end.

Real #GalaxyBrainChair people will tell you to "Just use #USBc!" but then you gotta show them #cursed #USB devices that ain't following USB - #PowerDelivery spec of just do the shitty #resistor that makes them just fucking #charge, so you get stuff like the #NintendoSwitch that acts as a #BatteryBank if you let it do so, as if anyone at #Nintendo ever wanted that or could reasonably assume this is an intentional #feature...

Continued thread

My suspicion is that the loss of power when plugging or unplugging any of the USB ports may be caused by the fact that the #PowerDelivery protocol has to renegotiate how much power to deliver (and/or request/receive) each time you plug or unplug something. This may or may not be a solvable issue, but I am not an EE.

At least the bigger battery means I don't have to think as much about monitoring remaining capacity when on the move from station to #train to #airport to plane, etc. …

@chrismarquardt Interessant...

Theoretisch müsste mensch quasi nen USB-Hub baun der PoE-Eingang upstream nimmt und zwei seperate USB-#PD-Treiber hat um jeweils individuell pro Port dies zu steuern.

  • Ich rechne mal dass dies explizit notwendig ist um Daten & Strom zu verteilen und dass "einfach nen 2-Port - Netzteil" nehmen keine Option ist.

Weil sonst kenne ich ein paar Powerbanks, die "Passthrough" erlauben und dadurch mehrere Geräte versorgen können während diese selbst Strom bekommen, allerdings schätze ich dass explizit #USB 3.0 & #DisplayPort #AlternateMode oder gar #Thunderbolt 3 & #USB4 unterstützt werden sollen, oder?

Do I interpret this correctly, @frameworkcomputer ?

You're working on a #ToolfreeSwappableBattery version of your laptops?

Cuz that's the one thing I really want to see - ideally on a 13" device!

Also please let me know once you got a #USB_C #PowerDelivery #Charger that can do 240W / 48V @ 5A because I could really use such a beast...
