Powering your projects using USB-C Power Delivery

[@BrianLough]

A piece of footage ended up on the editing room floor incorrectly! The IP2721 will accept the highest voltage the PSU offers that is less than or equal to what is requested E.g. if it's configured for 20V, but the chargers max is 12V, it will take 12V

[@andrewwhite8762]

Can someone please tell me if this chord (USB 3.1 Type C USB-C to DC 5.5 2.5mm Power Plug Extension Charge Cable ) can be used to take power from an Anker battery bank and deliver power to the Atomos Ninja V which has a DC connector for powering it from the wall. Essentially I am trying to understand if a chord which is used to deliver power from a DC source to USB-C can be utilized to deliver power from USB-C to DC. Can power flow either way in this case? Thank you.

[@Xiaoxiaoxiaomao]

Hi The IP2721 will charge my 90W laptop from a 12V Battery? Also The FUSB302 will charge my 90W laptop from a 12V Battery?

[@NetRolller3D]

@@BrianLough The FUSB302 chip can actually be used on the source side, but obviously it needs different programming on the microcontroller, plus external circuitry for the power conversion.

Just discovered your channel after watching Great Scott on USB-C. Lots of useful info in this video, thank you, subscribed. Currently trying to migrate as much of my life as possible to USB-C PD!

[@mdijkens]

Great video. Good info! One (important) thing to mention about the FUSB302 PDS-modules is that if they can' negotiate the set voltage (e.g. 12V) , they sometime take the next higher one (e.g. 15V) but does not show that with the led! This might be killing your project. I never use them in combination with a specific source without measuring first! BE WARNED

[@vince086]

One thing to mention, the Apple power supplies that come with laptops can also do USB PD but with a slight difference, it doesn't support all of them (12V & 15V are missing). So if you set your module to request a certain voltage, it might not match what the Apple one can supply. The sink modules ZY12PDS (looks like the FUSB302) supports a "request the highest voltage" mode that I use.

[@BrianLough]

Yes, you can't rely on all chargers supporting all voltage levels, the mac charger is a very good example of that! I think the nintendo switch charger only does 15v as it's max as another example

[@colindgrant]

You're right! I was just testing this out in depth. I have a 2021 M1 MBP 16" that came with a 140W USB-C wall charger, model A2452. It only offers 140W (at 28V) over the USB-C to MagSafe 3 cable. Using a regular USB-C cable, the PD options are 20V/15V/9V/5V. All at good amperage. But it skips the 12V level. So when I use it to charge a powerbank (that I've verified capable of accepting 12V PD input), it charges at 9V instead. The charge wattage is about the same as a 12V PD source, it just uses more current. What's really surprising is that on the Macbook side, the USB-C ports don't offer PD output! They are dual role ports (DRP), so they can accept a charge PD input of ~100W, but they only offer 5V/3A output. You would think that a modern, high powered Macbook Pro would offer the latest and greatest charging options to other devices. I made a video exploring this stuff, as well as the PD capabilities of one of the DIY 16x18650 Powerbanks found on eBay. The audience on this video may find it interesting: kzbin.info/www/bejne/r5qyk42epsuJeZI Great video @BrianLough, thank you!

[@daveyjones5702]

this topic might be worth revisiting. lots of new options on the market now. incl ones where you can set the voltage by bridging some pads and i have some that have a tiny set of dip switches for setting the voltage. easily broken out to proper switches and with some usb-c connectors and a panel volt meter module you can easily make a small volt selector box. i don't know if you do tutorial videos or anything like that, but i think it would make a highly satisfying project for beginners. easy to do and the result is something you might use quite regularly. and few things are more satisfying then making your own tools...

I have issues in charging my Vacuum cleaner with USB C, I have some more things to try out but it does not like that the PD does +50 watts, the charger is made to 33 Watts so although it begins fine with the charging it begins to fly into the heavens with the Effect 50-105 watts or so and then the robot stops and scream error.

I have an idea to charge my elictric scooter with pd Its charger puts out 41v @1.9A The conversion should be really easy but im struggling how to make sure i dont pump too much current And i have never tried it but my guess is the bms could charge at lower amps if i held the voltage just right

[@carl-marvin]

I'd love to see a similar small board with a 3-4 digit lcd, a potentiometer, and three switches. The first switch enables / disables the output, the second one enables / disables USB PD PPS for fine grade voltage control. And the third switch locks an once entered voltage, such that you cannot accidentally change it. When unlocked you can set the voltage with the potentiometer (Using an analog->digital converter inside a chip requesting the voltage from the source), and the lcd shows that dialed in voltage. For me, this would be the only board i'd find useful and safe enough to own and use. hopefully someone comes up with it. Otherwise i'd need to find a programmable usb pd (pps).chip + arduino control code to build my own one

[@ArtyMars]

Seems similar to the current Voltage and current boosters that you can set the voltage on

[@carl-marvin]

@@ArtyMars yes indeed. Just that with the board I wish the voltage is controlled directly by the power supply. That should be more power efficient and you probably get higher currents than if you go the route over 5V and a booster. I'm not completely into the PPS standard and voltage regulation though. It could be an alternative to get like 20V 5A/8A via USB PD out and then have a separate Step-Down converter to fine control the voltage. But getting access to the full capabilities of an USB PD PPS power supply still seems nice for tinkering for me.

Dear Brian, thank you for sharing your knowledge with all us! I have a bit of a problem I thought you might help me to solve. Please would you be able to think of a solution for the following: I have a 5v 2.5A LED Light I want to get powered through a Usb C PD battery bank. I tried so many different approaches and the best I can get is the light working pretty stable, but at maximum of 70% brightness. The Power bank is Anker 10k with Usb C PD. Bought a cable that goes from Usb C to Usb A and another cable that goes from Usb A to DC 5.5mm that goes straight to the light. First I thought the battery is not good enough, then after reading a bit I started to feel the cable might have some resistors that are reducing the current which then gets not enough for the light. As an example I connected that same cable set I mentioned to my iPhone 11 Pro PD original charger and the light acts exactly the same as when it is connected to the battery bank. The iPhone charger output is 5v 3amp. This is why started thinking there might be something wrong with the cable. I am lost now! I would really appreciate if you can help me on this! Thank you so much in advance!

Do you have any idea why this board is not delivering continous power in the first seconds? I tried 3 different boards from aliexpress, 2 with a switch for different output voltage and one with fixed 12V. Do you have any idea?

[@BrianLough]

I'm almost certain the negotiation phase happens at 5v, 10seconds sounds very long though! I can't say I've noticed anything like that before when testing

Hi, I am looking to power a mini pc with a rechargeable 19V battery. I was going to go barrel jack but I thought it might be fun to investigate usb c requirements. I am struggling to find something that accepts 19V but plenty for 20V, would those be essentially the same voltage for computers?

[@Me-123]

Question for anyone knowledgeable on this topic. I have an HP laptop that has a 4.5 barrel charger and a USB C port that does not allow charging. I'm using a USB C hub that is PD compatible with monitor, keyboard, mouse etc connected to it. The issue is I have to connect the OEM 4.5mm barrel charger and the USB C hub cable. I'm thinking of building Y splitter that on one side is a female that would connect to the USB C hub and on the other side a male USB C data cable that would connect to the laptop and a 4.5mm barrel connector that would connect to the charge port. Does this make any sense? Do you see any issues with this idea? Would I have to power the data side or I only need the data cables for that one? Any recommendations?

[@johnsenuzun1558]

[@carminone]

Does "current negotiation" mean setting the maximum current that the PSU should give?

[@BrianLough]

No, it's not like that. The psu advertises it's max current capability and it's up to the sink(device) to decide if that's enough. The psu will not limit the current at all

[@carl-marvin]

With chips supporting usb pd pps you can actually go into a constant current mode where you can first set a desired current, and then the psu tries to keep that current level by constantly adjusting the voltage in a range of 3,3V and around 20V (depending on the capabilities of that psu)

You showed a ZY12PDN module and called it FUSB302. Are you sure it‘s a FUSB302? Alex Whittemore found that the chip‘s pinout is similar but still different (see www.alexwhittemore.com/zy12pdn-reverse-engineering-part-1/). Do you have more information?

[@BrianLough]

We don't know for sure I guess, but the working theory is it's still the fusb302 . Vbus is an input according to the data sheet for "attach and detach detection" so maybe that is just disabled or something. I shared your comment on my discord and one of the guys said that he found some code in the firmware dump that suggests they might be bit banging the i2c, which means they could swap the two pins from the default of the mcu.

Hi Brian, I’m trying to design a custom charging system for my DIY electric longboard with USB PD (and a step up converter), however in order to future-proof my setup, I want to try to make my system compatible with the new 240W PD standard (and be able to request the highest voltage above 12V). Do you of or know how I could search for similar boards to the ones you highlighted in this video, but compatible with the new standard?

[@MCgranat999]

Not that I know anything about longboards but my suggestion would be not to use usb C on it, or any skateboard or scooter. Charging ports on these devices take a lot of abuse and usb C is too fragile and might break or corrode in humid environments or get clogged up with dirt. Take a look at XT60 or if you really need more than 60W, you can use XT90 for 90W. These connectors are a solid choice, most drones (DIY ones at least) use this standard because of its longevity and because it's relatively light. It will not fail on you, that's for sure, the last thing you need is a fire caused by worn out connector.
