@masukomi

I drooled all over this when it came around on #USBPD - It's stunning he could hang THAT MUCH off a PSU when most commercial wall units have a hard time coping with two 100w requests without derating/melting. Active/aggressive cooling ftw, I guess?

Can someone please #ExplainToMeLikeIm5 WHY THE FUCK DOES A #CHARGER NEED "#Cloud" and "#AI" 'features' or a shitty, non-self adjusting #Clock ???

  • Worse even: This isn't like some fancy "Lab Equipment" to do custom charge voltage and amperage curves or something where said settings may come in handy (Like needing to charge or discharge a custom cell / battery pack design/chemistry), but it's just a giant #GaN #USB #PowerDelivery block, so there is no reason to shove an #LCD (or even #OLED) into that case to begin with!

THIS IS NOT A "BENCHTOP POWER SUPPLY" WITH DIALS AND KNOBS!

Still using a slow charger? That's so 2024! Engadget drops the definitive guide to the best fast chargers for 2025, from GaN magic to multi-port marvels. Are you team USB-PD or still tied to proprietary tech?

@Cathoderaytube So yeah, outside of #POS setups and other spechalized nieches noone should use #PoweredUSB [even tho the specs are public] because #USBpowerDelivery / #USBPD & #USBc are a thing and they provide way more power (up to 48V @ 5A = 240W) with way more voltages [5V, 9V, 12V, 15v, 20V, 48V] and way more Amps [0,5A - 5A] supported.

  • So yeah, it makes sense in a #retail setup, but not anywhere else, which is why it's been nicknamed #RetailUSB as well...

They are selling USB audio amps that use a USB-C shaped 5V port for power and a dedicated USB-B for audio. You really can't make this up!

Checked into a hotel in Perth and very excited to find the power sockets do #USBPD and #QuickCharge.

Two things that never fail to make me sad:

  1. Paywalled Articles.
    Honestly why put it up at all when it is entirely useless? No one is going to pay you 3 "freedom" bucks for a generic article e.g.: linux-magazine.com/Issues/2025

  2. USB-PD (especially PD 3.1)
    99% of all PSU's on Amazon either don't support the full spec or come with cables that don't have an E-Marker. They, however, happily claim to do both.

Okay actually make that 3 things that make me sad. Amazon's "search" function. Best practice is to look at the last entry on the last page of results to find what you are actually looking for.

@s0 thanks for nerdsniping me into buying a pair of the GaN PSUs!

The EU variant is also too thick for the Type C "Europlug" sockets, but works well in Type F!

What surprised me is that they announce PD dual-role-power with a 20V/1.5A consumer, so they might be misunderstood as a powerbank by too smart PD devices?!

And it will (very slowly, ~3.5h) charge my idle ThinkPad L15, so might be a usable travel adapter after all!

ATOP just reviewed his stockpile of USB PD trigger boards - good stuff if you're shopping around in the "chinesium" eBay/Amazon/AliExpress pile for something that suits your needs:

I've had my eye on these power meters for a while. They come in lots of variations, with different ports and screens, but my big concern is how they handle USB power negotiation with various protocols. Does anyone have any recommendations for which devices handle , , and ?

Falls jemand zufällig noch eine brauchbare PowerBank sucht, ich hatte kürzlich zufällig bei voelkner im angebot eine für 50 euronen bekommen die 20Ah kapazität hat und sinnvoll USB-PD (mit immerhin bis 17W) beherrscht, mit kleinen einschränkungen.

Dafür kann sie aber auch "USV Modus", also mensch kann sie an ein usb ladegerät hängen und gleichzeitig 2 endgeräte zum aufladen drannstecken. Solange netz/externer strom kommt, reicht die bank das einfach durch und hält dabei den eigenen akku auf 100%, sobald der externe strom ausfällt, macht die powerbank einmal kurz "blip" und reaktiviert die ausgänge, die dann weiterhin vom internen akku mit strom versorgt werden....

Die einschränkungen sind leider; USB-PD funktioniert nur wenn die bank alleine am PD ladegerät hängt oder für _ein_ endgerät wenn es alleine an die Powerbank angeschlossen wird.. In jeder anderen kombination schaltet die powerbank auf normales USB 5v 1A runter.. Was aber als erhaltungsladung für 2 endgeräte durchaus auch taugt und ne ganze weile vorhält dank des großen akkus.

Achja und das sonderangebot gilt nicht mehr... Dafür ist der preis dann jetzt auch "nur" auf 19,99€ angestiegen. Kann mensch immernoch mit leben für die kapazität und funktionalität find ich. ;)

Falls wer also grad was sucht oder ne powerbank brauchen kann.

Diese hier hält was die artikelbeschreibung verspricht (hab sie bereits 2x wieder voll aufgeladen, die aufgenommene strommenge kommt gut hin mit den angegebenen 20Ah ;))

voelkner.de/products/12012474/…

Have fun ;)


P.s.: Meine USB-PD ""clients" sind bisher 2 Xiaomi Redmi geräte die an ihren originalen netzteilen easy bis 22~27W nehmen können. An der Powerbank regeln sie sich auf rund 8 bis 9v ein und kommen dabei auf 15~18w. USB-PD laden vom netzteil macht die powerbank ebenfalls mit 9v bei rund 17w, sowohl am xiaomi als auch am medion/aldi netzteil. ;))
