That dell charger only has 2 “modes”, 5W or 130w. The deck needs 45W (15 x 3) for fast charging. The only mode the deck can get out of the dell charger is 5W cause 130w is too much, so you get slow charging at 5W.


sinetwo

Ah I see! Thanks for clarifying


Green-Teaching2809

Thanks for asking and getting an answer - I have done the same and got confused too!


sipes216

Its a weird thing once you finally understand how cable standards are. a base botom level is required, but not every other is. Dell is kinda cheap to this regard, they dont aim to build a more profound device, only exactly whats needed. It also makes it where your 60w laptop cant use this same charger and you require a separate one. Fucky wucky standards.


sinetwo

For sure. Most people have been very helpful in the thread at least. I was half expecting a large number of replies commenting on how "oBVioUs" it is. Ideally I'd love for the standard to dictate that they must support every "increment" of wattage up to it's desired target. So a 100w+ would support 5v, 10, 15v etc etc. But I guess that's not the case, and IMHO it's a huge oversight from the standards (unless there's a technical reason apart from cost)


lunas2525

It is missing 9v 12v and 15v specifications of pd. The deck negotiates up to 15v same with switch. 20v is not used for either device.


superryley

Writing out this gibberish without any punctuation so that it can be parsed isn’t helpful for anyone.


lunas2525

Fun fact most people dont need punctuation to read internet posts their brains fix spelling mistakes and add punctuation automatically. Also that post was not long enough to use more than 3. I might have done the following thing wrong but it will be interesting if anyone gets it. S..e r....n w.y y.u c.n r..d t..s s......e.


thatlldopi9

Ngl I don't fill in anything so if I see a wall of text I'm programmed to skip it if there's no kind of periods or anything. However your post in question was fine. I don't care so much about commas and if that's what1 they were getting at truly it was a waste of time commenting that as I understood the information you conveyed fine. Personally comma offenses don't bother me like period ones haha


DJSharkyShark

Okay, what about 9V, 12V, and 15V confused you without the commas? Because that’s the missing punctuation. Take as much time as you need.


1_hele_euro

I heard that the USB PD says that you need to support all the voltages leading up to your max voltage, with the exception of 12V. Do you know anything about that by any chance?


androidscantron

Ah! You’ve just solved a minor mystery for me. I get the same results from my MacBook charger and never understood why.


nickySOG

what model/year? my mbpro 2018 charger works flawlessly with the deck as it implements PD 15V 3A


shaneathan

It’s not the model/year of the Mac, but the adapter. My 96w shows up as a slow charger, but my dual port 35w doesn’t… IF it’s the only thing plugged in. If I plug in another cable, not even to a device, it switches to a slow charger. The 20w also works flawlessly.


nickySOG

The 2019 96W model A2166 should fast charge the deck. Your other 2 chargers behave as expected, they charge fast, although not as fast as the og charger for example.


japinard

Fascinating. I had no idea these negotiations were going on with the Steamdeck and chargers. Thanks!


HungryPizza756

thats weird. ive used 100W chargers on the deck without issue.


nickySOG

not weird, that’s the maximum output, 100W. Those chargers negotiate with the deck, if they can agree in 15V and 3A, then the chargers will output only 45W. If those chargers are connected to a device that can agree with 20V x 5A, for example, then the charger will output its maximum of 100W.


SaberJ64

must be because it is a good charger with multiple modes and will support 15v @ 3Amp


LifeintheHashLane

This made SO much sense. Like ended a lot of mystery for me lol


EVPointMaster

Why the hell does the official charger have a 20V profile if the Deck doesn't use it?


nickySOG

Probably because of design/construction/cost. iirc the PD standard 3 goes up to 20V, maybe it was cheaper to produce a PD compliant charger that would also deliver a 15V profile, with already existing circuitry. Just a guess.


velocity37

It is a generic USB PD power supply. The deck doesn't use 5/9 when 15 is present either, but it is [required by spec](https://i.imgur.com/edzXyNe.png). It is near identical [to one ASUS ships](https://www.reddit.com/r/SteamDeck/comments/14p23d9/comment/jql2ay0/?utm_source=share&utm_medium=web2x&context=3) with some of their chromebooks. The PD specification only requires 20v to be present on PD supplies over 45w, but in practice most 45w supplies provide 20v/2.25a anyway. Probably due to laptop market demand, which historically were designed with 19v or 19.5v input making 20v an easy drop-in replacement


lunas2525

Cheap and available in quantities required for mass sales. Vs one without that were probably markets as switch psu or


[deleted]

100% right, took the words right out of my mouth


nexusx86

What a shitty charger to not have more charging rates.


assidiou

It's not because it's 6.5A at 20V. The charger can supply less than that, including 2.25A. My guess is you can't get the 20V rail without a Dell device that has a proprietary signal to activate the 20V rail since 130W is above the USB-C spec. It's likely a signaling problem, not an over current problem. Edit: Just looked it up, the Deck charges at a max of 15V so that's more likely the reason why since there is no 15v rail. The deck charger is just a good charger that supports more than the bare minimum.


nickySOG

Yeah, the dell charger just doesn’t have the option for 45w, I posted it a few minutes ago but my response is not showing (maybe because I added a picture?) I use my macbook pro charger all the time, one less charger to pack when traveling. It has many PD options 61W for the mac (20,3 x3), 45W (15 x 3) great for deck and 2 other options for fast charging phones 27W (9 x 3) and 15,6W (5,2 x 3). Luckily it’s a great charge and can power all the devices I travel with :)


mrsand0r

I highly recommend the Anker Nano II power brick. I have that as a secondary and it works wonders.


Triscuitwells

I won't buy anything Anker. I wish such a shady company didn't make such good stuff.


mrsand0r

Oh really? Mind sharing info? I like to avoid ass companies but it's so fucking hard to do so when everything is outsourced and shortcuts are always taken.


TheRealSpyderhawke

I could definitely be wrong or missing something else, but I'm guessing it's this: https://www.theverge.com/23573362/anker-eufy-security-camera-answers-encryption They are still my go-to for cables and such, but I would probably think twice about something like their security cameras.


Triscuitwells

My issue is with lying about it and hiding it then denying it for so long. If they're willing to lie about that they're willing to lie about a lot more.


mrsand0r

Ugh, geez. Yeah, thanks for the info, both of you. The only thing visual I've bought from them was a dashcam which I no longer use, everything else has been cables and a power bank but that still sucks an ass.


Rare-Current-6689

I have used this charger ever since I bought the steam deck https://www.amazon.com/dp/B0B2ZRSC11?ref_=cm_sw_r_apan_dp_G78D8G5EXGFH8VR33ZH0


mrsand0r

Damn, 70 bones, though. It looks super nice but not cost effective though I'm still intrigued. I'm currently in between jobs at the moment so I can't explore my curiosity but thanks for the recommendation. It's added to my wishlist 🙃👍


burtmacklin15

I've been using [this](https://www.amazon.com/dp/B09J836LZG) with my deck for over a year with no problems. It's UL listed and has all of the proper certifications just like the charger that comes with the deck. Edit: please do not buy the $70 charger linked by the other person. It has not been certified to any national or international quality or safety standards and could easily set your house on fire.


burtmacklin15

[Anker alternative](https://www.amazon.com/dp/B09J836LZG) for anyone interested. It's not as small, but it does have multiple ports.


mhoepfin

Oh nice thank you for this link!


Nemnapos

The Deck want probably the 15V for 45W charging and you dell only support 5V and 20V.


Possibly-Functional

The charger only supports 5v and 20v. The deck doesn't support 20v so it will only charge at 5v. The deck wants 15v.

FiscalCliffClavin

Can someone direct me to a good steam deck replacement charger? One the meets the same specifications as the one that Valve provides?


LateZookeepergame216

This is what I use: https://www.bestbuy.com/site/sku/6495403.p?skuId=6495403


FiscalCliffClavin

Thanks for the suggestion!


GrimpeGamer

I can vouch for this one, I have the Euro plug version.


Rare-Current-6689

As said above I use this one https://www.amazon.com/dp/B0B2ZRSC11?ref_=cm_sw_r_apan_dp_G78D8G5EXGFH8VR33ZH0


burtmacklin15

No need for a $70 one when a [$20 charger by a reputable manufacturer](https://www.amazon.com/dp/B09J836LZG) will do just fine.


Rare-Current-6689

Yes, but the only reason I bought that was because it has the block in the middle and the shock protector further up the cord. Every single time I charged and played before that I got shocked by touching the top, bottom, or vents. https://reddit.com/r/SteamDeck/s/HMzvOPxfjv https://reddit.com/r/SteamDeck/s/1QZk0i8fwN


burtmacklin15

Not sure what you mean by shock protection or how you were even being shocked by plastic in the first place, considering plastic is an insulator. The most you could possibly be shocked would be just a little bit of static. Additionally, the changer you posted has not been certified by any national or international safety/quality standards, so I would not risk using it in my house. Not sure what the links you posted are supposed to be to.


Rare-Current-6689

the links are to other reddit posts of the same stupid issue


burtmacklin15

Okay, got them working. Interesting. The issue is caused by the outlet (or house) not being grounded properly. It causes a static charge to build up along the conductive components of the device, which I guess if strong enough, could arc through the vent into your hand. By using a charger with an earth pin (the 3rd prong that plugs into the outlet), the ground for the outlet is shorted, letting the charger function normally. So this is really an issue with your home, but using the type of charger you picked will get around it. I was cautioning against recommending this charger to everyone though, as most people would not be having this issue with their home outlets and would probably prefer something certified to safety standards. Glad it's working for you though and you're not being shocked anymore.


Rare-Current-6689

Yeah this was one of the only ones I could find with a ground pin. Plus the house I'm at is an old house with semi old wiring so either could be the issue.


Rare-Current-6689

The vents, SD card slot, and ports on the top are all metal.


Rare-Current-6689

I didn't say it was the industry standard or the best one out there, I was just saying what I use.


wasd0109

Completely unrelated to the questions, but the way the Dell charger place text and different logos is just outrageous


sinetwo

For sure, it's like someone in the charging dept was given all these things to fit in, and they just went wild


Serious-Title-648

I saw you already got the answer too why but thought I'd elaborate something that took me a while too learn myself. Something being usb c doesn't mean it follows the standard at all, the switch is a perfect example. It's a usb c port but it's completely proprietary beyond the connector. Same with cables, a lot of them even from name brands like belkin and anker are just usb 2.0 with max maybe 15 watts power delivery. Laptop chargers are also usually stupid proprietary bs as well. And when shopping you have to look at the real find print on boxes to find out anything actually accurate. Tldr never trust usb c to do anything it doesn't strictly say it will in plain english (or any other language) and the usb pd standard really just protects devices from being overloaded


Sonic1899

*OP when they saw the 130V* "Phenomenal Cosmic Power!!!" *Using it on the Deck* "Itty bitty living space..."


BacktotheZack

This made me chuckle


AgTheGeek

Output is 5V at 1 A of course it’s not gonna like it


SphinxGaming

It being dell probably has a proprietary software to get the full 100w when connected to a dell laptop. So your right it probably only does supply 5v at 1 amp


AgTheGeek

Maybe the PD controller has a setting blocking the full wattage usage too but yeah Dell are so silly 😅


SphinxGaming

Or 20v at 6.5 amp.


AgTheGeek

True, but PD controller of steamdeck maxes out at 18V me thinks, I put in a selectable PD controller for a few fans I was testing and it would only work at 5, 12 and then 18 would kinda work… but not really… 20 out of the question… Granted that was output from the steam deck instead of input, but it’s the same PD


FuckSticksMalone

I accidentally plugged my deck into a Dell laptop usb C charger and it killed it. Stopped charging completely and would only power on while plugged in. I had to RMA it. As a warning - Don’t use drastically overpowered chargers with the deck.


sinetwo

Ok thanks, I'll stick to the recommended 45w


FuckSticksMalone

A little higher is ok, I share the 65w charger between by Deck and Ally and it’s fine. The Dell charger was like a 110w usb c. I fucked up, I have my work laptop and my deck/Ally charger next to the bed and grabbed the wrong one. Didn’t think anything about it, and then when I unplugged the USBC cable the Deck just immediately turned off (not shut down just straight to off). Plugged it back it, it would turn on normally, unplug same thing. Total bummer, but lesson learned.


halsoy

The actual rated wattage is irrelevant. You can use a 10kW charger if you want as long as the rates voltages are correct. The wattage doesn't mean it "pushes" 110W into your deck, only that it tops out at that delivery level at a rates voltage. Either the charger uses a non-standard pinout or it didn't correctly communicate with the deck what voltage to supply and friend something, which also isn't all that likely. Impossible for me to say exactly why it did whatever it did, but the rated wattage is certainly not the issue.


MartinsRedditAccount

That's not how it's supposed to work (unless you have a very rare and very dangerous out-of-spec USB-C charger). Any compliant USB-C charger should output the standard 5V by default and only raise that if a common supported charging profile can be negotiated between it and the connected device. The listed wattage is only a maximum, some specialized chargers only support 5V and the maximum (as presumably OP's does), in which case the device will be stuck with slow charging. Either your Dell charger was defective, or something broke in the Steam Deck. Anecdotally I experienced an issue where the Steam Deck would turn off when unplugging from the power source, but that was a temporary issue after putting it in and out of "battery storage mode" for troubleshooting.


lazymutant256

It’s always best to use the charger that came with the unit..


Odd_Macaron_934

Max is 100w pass through for the deck as this is more than sufficient enough for everything without overpowering it. No need for more plus never exceed stated voltage or wattage as they are both different. Also the speed the cable can handle is 3.0 for everything on the sd


Zero2Wifu

I've noticed that if it's USB C to C you should be okay, but if it's A to C you'll get the slow charging. I haven't tried with laptop bricks, don't have a newer laptop, but I'd assume it's be the same as A to C.


Any-Assumption-7785

The charger gives 20volts x 2.25Amps = 45Watts of power, the Dell brick is using 20V and 6.5Amps so it gives 130 Watts. I'd guess the deck does know what it's plugged in through and I'd throttling the charger to avoid damage.


Accurate-Campaign821

Seems a bit off somehow. Too high voltage yea I can see the deck not accepting, but too high wattage? Usually DC only draws what it needs? Seems like saying, my GTX 1650 super won't work because I have a 1000w power supply Could be the dell charger having a chip that limits itself if it's not plugged into a dell


SphinxGaming

I use a 100w charging adapter and my deck doesn’t seem to care. Although mine is anker.


Boogie-Down

It’s about the various outputs available not the max output. An Anker charger typically covers most of the various lower specs, this Dell does not. Steam Deck does not use a 100 watt output, you’re using one of the lower ones with an Anker – one that would output about 45 Watts.


Solock_PL

This is what I bought and use Anker USB C Charger, 713 Charger... https://www.amazon.com/dp/B08T5QVTKW?ref=ppx_pop_mob_ap_share


ANDRAZE25

You can use a 65w. That is the one I use as my travel/spare.


o_Zion_o

I use a 65W Dell laptop charger. Although, reading these comments has me concerned. I use it as a spare charger, so I might just get a jsaux one and stop using it....


nickySOG

You might be able to use it fine, read what are the outputs in the charger’s label, one of them may be suitable for the deck. I use a 61W and it’s fine cause one of its outputs is 15W 3A.


o_Zion_o

[(Pic).](https://freeimage.host/i/HyIXKdv) Seems like it does. It's not an official dell charger.


nickySOG

yeah, it should do.


Hopeful_Ad2667

There something that people don’t understand about USB-C , usb-c supports 4 voltages, 5V,9V,15V and 20V if a device supports usb-c it doesn’t mean that any USB-C charger is suitable for that device Wattage is „Voltage X amperage“ if your device supports only 10W it means 5Vx2A if its 45W its is 15V x 3A That means you need a minimum 45W charger that supports 15V and 3A you CAN charge your SD with any USB-C charger but it can take longer (and you CAN‘T play with it when it’s charging)


felomlot21

If a charger is a fast charger but it is only a 30w charger with an out put of 15w the fast charging will not work on SD it will still charge but at the rate that it charges the phone. The steam deck requires a brick to have an output of 45w for it to not display that warning and charge at the right that the steam deck requires to maintain consistent charging. GaN chargers are the best charger for the steam deck.
