Steam Deck OLED charge speeds

[omicronpersei8]

I noticed with a new OLED steam deck the charge status LED is white with the Valve charger and orange/green with any other charger (Pixel 15W, Apple 20W, etc).

Upon further testing:
- Pixel 15W or Apple 20W USB C chargers have green/orange LED and extremely slow to charge. 10 hours from 50%. TEN HOURS?! Changes to green when fully charged.
- Included charger has a white LED and fast charges. Approx 1 hour from 50%. Changes to green when fully charged.

I also could not find anything in the FAQ about different LED colors but orange/green seems to indicate slow charging.

Why would the deck not fast charge on higher wattage USB-PD chargers?
Even a 15W charger with the deck in standby should 50% charge in way less than 10 hours.

I need a USB C power analyzer to figure out what is going on with the charge current but it appears to fall back to a very low wattage/PD profile with any other charger and is possibly not properly negotiating PD profiles?

Edit: Adding some analysis.
I did more testing with a power meter. All are USB C chargers. Non PD means the power meter says it is not charging via negotiated PD.
Pixel 18W - 14W non PD
Apple 20W - 14W non PD
Apple 30W - 27W PD
Apple 61W - 41W PD. White charge LED
Apple 87W - 11W non PD
Apple 96W - 41W PD. White charge LED
Apple 140W - 41W PD. White charge LED
Anker Nano II 45W - 41W PD. White charge LED

For reference the Valve charger is a 45W USB-C power supply with "Power Delivery 3.0". It shows a White charge LED.

You realize that your comparing a Cell Phone to a Micro PC right?

Also based on my experience as I'm drowning in cell phones (part of my job is to test games for my company) - the Steam Deck charges bloody fast.

So unless you have an obvious fault - I'd doubt you have an issue at that rate.
Id suggest investing in an USB Power Meter that you can plug in-line if you really want to dig deep.

Even if for this once instance - its handy to have when you have USB Devices all over the place.

Also make sure your plugged into a clean power source at that rate.

Here’s my charge results the past few days of owning the oled.

Oled been charging with two different anker powerbanks from 44.1w-44.5w during downloads and gameplays. It’s always been white led then turns green at 92% battery. This is same for when I use the included wall charger and a 65w anker wall charger+cable.

Hope that helps.

The deck needs PD 3.0 or newer charging protocols. If your power supply cant provide that, the deck will charge at 10W or less, even if you use 22.3W QC 3.0 charger.

Get a Cto C PD 3 or newer charger, or use the one valve supplied.

[omicronpersei8]

Yes, I agree when using the Valve charger it charges very fast! And yes, I'll continue using the Valve charger for now.

I understand the 15W pixel charger would not charge as fast as the Valve charger, but 10+ hours at 50% for a 50Wh battery does not math out. So my conclusion was that both the Pixel and Apple charger were dropping to some far lower speed.

@Waldherz do you know if any variant of the Apple USB C chargers support PD 3.0? It is hard to find details about them, and I have several wattages on hand.

And would you happen to know what voltage/amperage profiles the Deck uses? I'm not sure why it can't pick a PD1.0 profile (one of the six power profiles, etc). Maybe it is too complex and they need the flexible current capability.

If you have any referrals for a power meter that displays charging protocol please share.

Thanks all for the feedback.

These are my gears if it helps you. 15w is also way too low for SD and needs faster PD.

Powerbanks:
• Anker 737 Powercore III https://a.co/d/7z7pIXg
• Anker A1336 20,000mAh https://a.co/d/9V3M9EP
• Anker A1335 12,000mAh (for smaller travel companion) https://a.co/d/1Vs8AG9

Wall Charger:
• Anker 715 Nano II 65w (travel companion) https://a.co/d/4JvIZac
• Anker USB C Charger Cable 100w https://a.co/d/eRd4MMn

Thanks, I ordered an Anker 713 45W and a 10' cable since they are on sale today.
Looks like it may address one other minor complaint, the Valve charger doesn't fit in the bottom of the case well.

[Jenaverse]

I remember a review about the 713 too weak or something while the SD is in use, so I bumped up to the 65w just incase. It should fit just fine in the bottom case housing.

I don't know how the pixel charger looks like, but if it's USB-A to C then it will charge at 2.5w, or 16h for LCD and 20h for OLED.
Also, is Apple charger actually PD or is some molested Apple standard?
Usually PD chargers work fine with the deck.

Actually I have a few USB A Chargers that get the deck to request 9.8W from them, which is weird but hey. Seems like Xiaomi chargers can trick PD devices to deliver more than the most basic USB currents.

is it one of those custom xiaomi chargers with a fifth pin? I don't know if deck supports the ancient and seldom-used PD 1.0 which did work over USB-A, however USB-C PD needs the CC pin which is missing on USB-A chargers.

Pixel are USB C PD chargers. One is 15W (5V 3A) and one 18W (5V 3A and 9V 2A).

I'll report back when I receive the new Anker 45W charger but I'm fairly confident it will charge at full speed based on reviews.
I don't know why I wrote Apple 60W earlier as that does not exist. I think I meant 20W (the iPhone charger).

I did more testing with a power meter. All are USB C chargers.
Pixel 18W - 14W non PD
Apple 20W - 14W non PD
Apple 30W - 27W PD

Apple 87W - 11W non PD
Apple 96W - 41W PD. White charge LED
Apple 140W - 41W PD. White charge LED

The white LED appears to indicate receiving max power. Green/orange for anything less.
I don't know why the Apple 87W does not support PD with the Deck. Apple does not sell this one any more and in fact several of these sizes wattages already been replaced.

what do you mean by PD/non PD? aren't all of these chargers USB-C?

Also, since you have the OLED, it has a new charging chip, so my and your experiences will be different...

Call me crazy - but if your using the non-factory charger - don't expect things to behave as expected. Especially on the new OLED.

the whole point of USB-PD is that you can use a single charger for all of your devices...

Not all chargers are equal.
A frequent and very common mistake made by users.

So yes - you can use your charger - but you lose the right to complain if the 3rd party charger fails to charge to "your" standards - let alone "factory" standards in terms of full charge speeds.

This isn't rocket science.

This isn't a cell phone or a tablet we're talking about here.
It's closer or more akin to a Laptop.
