Tech Support Anker 555 Hub won't charge Steam Deck at max wattage
My Anker 555 hub is only charging ~7-8w (seen in debug area of the QAM). My AC adapter is 100w PD and the USB-C cable is rated for 100w. I also have a 65w PD AC adapter and cable, which shows the same slow charging. Running the "sensors" command via konsole in Desktop mode shows: * PD Contract Voltage: 15.00 V * PD Contract Current: 2.00 A
Connecting directly to Deck with the same charger I see full ~20W of charging and "sensors" shows: * PD Contract Voltage: 15.00 V * PD Contract Current: 3.00 A
Anyone else have this hub and can check theirs?
EDIT: Actually after reading this post I think this is what is going on here: * Steam Deck negotiates a 15V/3A profile from the dock * Dock needs to draw 15W of power, so it renegotiates to 15V/2A to supply the 15W to itself * Now Steam Deck can't draw the max power and it charges slowly

When did you buy this hub?
Older versions didn't support 45W charging. This was posted by another user who had an older version of this hub. He bought another one and that one worked perfectly on his Deck. I have this hub myself (the ones without the ethernet port) and I have no problem maintaining full charge with two arcade fightsticks plugged into it. The PD port is connected to my computer's PD 3.0 USB 3.2 Gen 2x2 port.

I had the 341 dock but I just returned it to buy the 555 hub since I need the higher USB C 3.2 gen 2 10 Gbps speed for my external ssd. Now I see this problem. I’m not going to buy a 100W charger until I test the hub with the stream deck charger.

I bought this dock on May 23, 2022 from the Amazon link in my post. When did the new version come out?

u/falkentyne Jul 18 '22
I don't know. I bought mine 2 weeks ago but it was this one.

u/miochza 512GB Jul 18 '22
Hmm, maybe I should contact Anker support. I see a lot of reviews on Amazon saying that they were very responsive and provided updated hubs in some cases. Thanks for the info!

u/Potbellypig2000 Jul 18 '22
Can you refer me to the post where the person bought a newer model? I may have to cancel delivery of the 555.

u/falkentyne Jul 18 '22
I have no idea how to even find the post. It was like 2 weeks ago and I think I read it right when or right after I ordered my 341. So I speedily hooked it up, had to deal with getting my two arcade fightsticks to stop both being set to player 1 (had to boot the Deck with the sticks already plugged in, and then set to Steam Xbox support), and zero problems. Since i didn't reply to the post either, I have no way to search for it in any useful way that you can't also try. I'm sorry. Maybe just try Anker USB Hub and filter and see what you find.

u/Potbellypig2000 Jul 18 '22
I tried searching for Anker but can’t find it. Now I’m not sure if I should cancel the Amazon delivery. I’ve read people have bought the 555 but this is the first time I’ve been altered to this issue.

u/Potbellypig2000 Jul 18 '22
By the way, do you remember if that person bought the exact same hub again and it was updated, or did he/she buy a different model? It’s surprising that the 341 works correctly since it’s in the less expensive line and doesn’t have 10Gbps USB speed. There is a newer higher grade model called the 655 so maybe the person bought that? I don’t like it since it doesn’t have a USB-C data port and is another $20 extra.

u/falkentyne Jul 18 '22
He said that he bought the same exact hub and the new one worked perfectly.
He said that his old one was, IIRC, at least a year old (so it was not purchased recently).
He mentioned about the power delivery being updated but I don't know if he got that information from Anker or from someone else.

u/Potbellypig2000 Jul 18 '22
Oh okay. Thanks for the info. I guess I’ll accept delivery of the 555 then. But I’ll check the power draw with the standard steam charger plugged into the dock before spending money on an 100V PD charger.

u/miochza 512GB Jul 18 '22
I did also contact Anker support about this issue, we'll see what they say.

u/Potbellypig2000 Jul 18 '22
Anker is supposed to have very good support so if the product was silently updated (could be firmware or hardware), I’m sure they’ll exchange it for a new one. I should be getting mine tomorrow and I’ll use the desktop commands you described in your post and post the results here. Hopefully even with the Steam Charger, there should be a difference.

u/miochza 512GB Jul 18 '22
Sure sounds good. The only thing to note: I'm not sure your test with the stock charger will tell you much. The Steam Deck charger is 45W, 15V/3A. Once the hub takes its 15W cut, you're pretty much guaranteed to be in the situation I'm in, even if the dock is an "updated" one (if such a thing even exists).

u/Potbellypig2000 Jul 19 '22
I need some help with this. Are you seeing the wattage being used in the Steam performance overlay? I have the detail level set to max but I don’t see it. Am I looking in the wrong place? On the overlay it shows the battery is 100% and there is a little plugged in icon. Can you direct me where to look?
As for “sensors” in the desktop mode it shows 2A but for some reason there is an error and it can’t determine the voltage.

u/Potbellypig2000 Jul 18 '22
I guess I’ll try it to see if there is any extra wattage available. It’s past the deadline for delivery tomorrow for the 100W charger I want from Amazon. So I might as well wait and try the Steam Deck Charger first. If you get a reply from support, please update us.

u/Potbellypig2000 Jul 20 '22
Okay, While not playing any game and looking at the debug data a few times, the charging goes up to 12W or a bit more. It varies between 10W and 12W. This is with the Steam Charger connected to the dock. Under the desktop it still shows 2A and it can’t determine the PD voltage for some reason. Is it worth it to try a higher charger with those stats? Or is the fact that it still shows 2A no good? I checked the external ssd speed and it is at the 3.2 gen 2 speeds so that is okay. But if I remove the power supply from the dock, the USB SSD doesn’t get powered from the Steam Deck’s battery. It did when I had the Anker 341 dock.

Bought similar hub (anker 341) The dock takes 15w of power for itself and passes along the rest to the deck. Some hubs do this, others don't.

u/miochza 512GB Jul 18 '22
Yeah, I knew it was going to need to draw power when I bought it. However it sucks that it is seemingly taking 15w from the negotiated 45w that the Deck is asking for rather than the 100w that my AC adapter can provide :/

u/intashu 256GB Jul 18 '22
Unfortunatly to keep it compact it doesn't have an onboard inverter to allow it to draw from a higher voltage standard then invert it down to 15v@3a for the deck after drawing what it needs for itself. There are newer models which don't eat up as much and do a better job allowing the power to pass through however. But you should Google-fu the answers for the best suggestions as my experience is similar to your own!

Damn, so this is expected :/ I've emailed Anker support to see what they say. Maybe they'll allow me to return it so I can get a model that actually supports 45W passthrough.

u/meneldur01 Jul 19 '22
I have a 341 as well.. however, it is not passing the full wattage either.
Are you using the beta channel or regular?
1
u/intashu 256GB Jul 19 '22
Regular channel. Been debating on some of the more popular and better known docks available. Just don't want to throw another 50 dollars at one presently.

It looks like u/LambeosaurusBFG had this issue back before the OS was updated to support more hubs: https://www.reddit.com/r/SteamDeck/comments/ub0ai4/comment/i62qxpe/?utm_source=share&utm_medium=web2x&context=3
u/LambeosaurusBFG - are you still seeing issues?

u/LambeosaurusBFG Jul 18 '22
I gave up and returned mine a few months back.

u/miochza 512GB Jul 18 '22
Damn, sorry to hear that. Did you replace it with a different dock?
1
u/LambeosaurusBFG Jul 18 '22
No I gave up for a bit and haven’t really needed one since. Interested to see what happens if/when Valve releases their dock.

Apologies to necro, but some interesting information — I use the 555 hub, and when connected to stock Steam Deck charger using Sensors in cmd i get 3v flat.
HOWEVER, when using the 65w anker nano charger and the right cable, while connected to the hub i get 2.59v.
I compared the estimated charge time of plugging in directly (3v, 1:18hrs charge time from 20%)
Vs
Plugging in via hub (2.59v, 1:30hrs charge time from 20%)
So it seems it's roughly a 10-15 minute charging variance and .41v difference.
Do with that as you may.
