Powering the Pi 5

[camp .]

    Has anyone found a battery bank that can supply 5A to the Raspi 5? The battery banks below are labeled "PD" and "Fast Charge," but the Pi 5 reports "This power supply is not capable of supplying 5A power to peripherals." It appears they can only source 3A. The CanaKit AC adapter at the bottom apparently sources 5A, as the Pi5 doesn't complain. I want to avoid lithium/buck converter and active hubs.

I have not, and thus am building one. The 5v5a is not part of the specification, so it’s unlikely that really any power banks will support it.

You best bet is to get a USB-PD initiator board, set it to 9V 3A (which is in the PD spec) and use any of the 5V 5A converters that have been mentioned on the mailing list before :)

Note that your USB cable also needs to be "PD".

From what I understand, if the power supply does not "talk" the PD protocol, then the Pi will assume it can only do 3A and only draw that much, while reporting that error. You can find instructions around on how to trick the Pi into drawing 5A and not reporting that error.

I agree. The 5v PD spec really is 5v and the pi wants 5.1.

Make sure the dc to dc converter can be tuned a tiny bit higher than 5v.

Yes, I have successfully powered a RasPi5 /4G with an attached Oak-D-Lite from both 30kma/PD25w Power Bank and Lipo/Buck-DC-Converter. I followed advice from others on this Forum provided the Raspberry Pi Documentation  Bootloader eeprom property "PSU_MAX_CURRENT = 5000" is set. $ sudo rpi-eeprom-config --edit and add this parameter & reboot. Otherwise Pi Robot won't boot or will be unreliable. If set, this property instruction the firmware to skip USB power-delivery negotiation and assume that it is connected to a power supply with the given current rating. Typically, this would either be set to 3000 or 5000 i.e. low or high-current capable power supply. !! Be careful but I have done this a couple robot builds with no blue smoke. Run $ sudo vcgencmd get_config usb_max_current_enable to check the set max USB current. BTW: I believe the RaspI 5 only available configuration profile is 5v/5A so higher PD Voltage from PowerPacks or Official AC Supply has no benefit.

Other options with Lipo Batteries are the 52Pi PD power Expansion Board $30 USD amazon.com and mine failed after 2 days, Yahboom Power Expansion Board $13 USD RobotShop.com shipped from NewYorkState.  

And lastly, many of us appreciated the information in this Articulated Robotics  video who explains the above parameters.

I don’t think such a charger bank could exist.   The way the PD spec works is if more power is needed, the power supply raises the voltage up so as not to have a large current on the USB cable.

If you really need to put 5A into a Pi, you should bypass the USB port and solder to the 5V input.    I say solder because those 0.1-inch pins are not rated for 5A.    But really, if the goal is to power peripherals, maybe it is best to bypass the Pi and power them directly.   At 5A, you are getting into the range where damage to connectors and PCB traces can happen if you don’t read specs carefully.

This is what I will be using … won’t be until after this weekend though…

Well, contrary to what I said yesterday on the ROS2 SIG, the combination of a 30+ W Power Delivery–capable power bank and a 52Pi PD Power Expansion Board might actually work. My apologies for dismissing it earlier — I guess I’m still mentally stuck in the era of 5 V power banks.

That said, it likely won’t work for very long. There’s the obvious capacity limitation, and then the less obvious circuitry gremlins, which come with the exciting possibility of sudden power loss and the release of magic gray smoke.

I still think this is a somewhat strange way of solving a fairly straightforward problem, but that’s just me. Personally, I find connecting two wires between a decent LiFePO₄ battery and the 52Pi banana jack to be a lot less insulting to one’s intelligence.

Looking forward to live reports from the battlefield. Keep your fire extinguishers — and backup SD cards — close at hand. 😉

The problem with the lithium battery solution is it would involve buying a special charger($$$). Not a problem for me because I race RC cars but for a new person trying to build a MockBOT that would be an added expense; perhaps an argument for a using a Pi4 but for video processing the speed of the Pi5 would be nice.

Camp,

Ok, your argument is fair, but your building advice should, probably, come from your team's personal experience and with some calculations.

You cited two INIU 45W Power Banks in your first email (~$25). Here is one: https://www.amazon.com/dp/B0DCHWWBNS

Citation: "The capacity of 10,000mAh is stored in an incredibly slim body that is 25% smaller and 15% lighter than similar capacity, making it easy to carry without the bulk"

How I read it: There is a single to triple LiPO 3.7V cells inside, the spec (10,000mAh) is traditionally re-calculated to a single cell configuration.

                      Here is the Wh calculation: https://share.google/aimode/GQNmj14AO1XZuZCHS  (it is at best a 37Wh device)   - note: AI links expire in 7 days

Now, at 2A/5V (10W) the RPi 5 consumption the 37Wh  will last  for approximately 3 to 3.5 hours in real-world conditions.  (https://share.google/aimode/zmSUEU92AB2500cIz - note the "Factors Impacting Runtime")

That's a lot of time, if you can confirm it in your own testing - that's fine. "The proof in in the pudding".

As you've noticed, I am a big skeptic when it comes to battery ratings (and manufacturer's claims overall). With your experience building things - you probably are in this club too.

So, my "build once, pay once" conservative solution would be:

- A couple of 10Ah 12v batteries: $70 -  https://www.amazon.com/GOLDENMATE-LiFePO4-Lithium-Waterproof-Phosphate/dp/B0DJ2HXDM1 

- LiFePo4 battery 12v charger: $20 - https://www.amazon.com/LiFePO4-Battery-Charger-Phosphate-Batteries/dp/B0D8W1THH6

- 4.0mm x 1.7mm Male Power Pigtail Cable for 52Pi board: $9 - https://www.amazon.com/dp/B087C34RJ7

- A set of 30A diodes for power hot swap: $10 - https://www.amazon.com/BOJACK-Schottky-Parallel-Protection-Rectifier/dp/B0C7L3JGY4

I'd guess the builder already has wires, soldering station, flux, connectors... well, I am being a hopeless optimist here, I know ;-) But - giving your builders some alternatives wouldn't be a bad idea.

And here is some valuable artwork as a bonus:

Best Regards,

https://forums.raspberrypi.com/viewtopic.php?t=357130 is an very
interesting thread on the subject.

Even the USB-C cable has to play nicely (indicate that it can deliver
5A), for the source to switch to 5A mode.

So, for a Pi5, things can get ugly fast 'in the wild'. And especially
with many/different attached peripherals, you could hit the 'wall' at
random times:-(

Commenting on Camp's Question about using a PD25w/3a Power Bank to power a RasPi 5. I tested my PD22.5W/3a 30kma Bank 1)with eeprom edit "PSU_MAX_CURRENT=5000" and 2)without. Results: 1) WITH EDIT : Running $ vcgencmd usb_max_current_enable=1. i.e USB=1600ma. A ~1amp OAK-D-LITE worked displayed image on RasPi monitor 2) W/O Edit:  usb_max_current_enable=0 i.e. USB limited to 600ma, powered RPLidar & Logitech dongle but not power a 1 amp draw OAK -D . Scary Warning appeared . On Reboot would not startup a second time. Had to reboot with an official AC Supply (which is PD25/5A) to redo the eeprom edit to 5000 which restored Power Bank operation. Phew! Lesson seems to be: A suitable rated Power Bank appears to power a RasPi5 w/o eeprom edit allowing  <600 ma USB connections OR  RasPi 5 with edit to total 5A and 1600 ma USB connections. 

ps: A eeprom edit is NOT required to use the PD25/5A Power Supply and for some reason even though my 2 year old Power bank has a PD Specification does works ONLY WITH eeprom edit. Maybe more recent models do? Caveat Emptor. 

Cool schematic from Sergei Ross

    I'm reporting back on the "52Pi" PD Power Expansion Board for Raspberry Pi 5 and can report that it makes the "PD" and "Quick Charge" battery banks (3A) a viable power supply for the Pi5 (at least the 5A error message goes away). What's interesting is that if I try to power it via USB 3.0 (900 mA), it reports a low-voltage condition - no such error message with the PD and Quick Charge banks.

Camp, What is the result of running this is a Terminal? $ vcgencmd usb_max_current_enable . I suspect it reports usb_max_current_enable=1 which I believe means max USB current is 1600ma and RPi PD negotiated 5A current . By your report the 52Pi PD Power Expansion Board seems to have been able to establish required 5Amp capability as I observe your 3A/5v Power Bank can provide 45 w and 12vdc which meets the 5v5A RPi requirement.  Neat trick :) That 52Pi seems like a viable and flexible powering solution being able to use either 1) PD Compliant 5, 12 and higher input voltage from compliant Power Banks and 2) 9-25 volts from a LiPO RC Battery. A bit of a downside is that gets a pricey delivered to outside US users though it is available directly from China even cheaper fro some users..

[Pito Salas]

Here’s my contribution…

You see here (sorry for the messy pic) a Raspberry Pi 5 connected via USB3 to a PlusRoc (waterproof!) buck converter which supports PD. There is a display showing the voltage and current and all powered by a talent cell 12V battery. 

Ubuntu boots fine, everything seems ok. No low voltage messages. 

Interesting (to me) is that the Pi draws 0.25A when running ubuntu and half that when I shut down ubuntu. What is the processor doing without ubuntu just sitting still? 

 

[Ansel Halliburton]

Here's one more option, found via a cyberdeck-focused Discord:

UPS Module 3S by Waveshare

https://www.waveshare.com/ups-module-3s.htm?sku=23884

https://www.waveshare.com/wiki/UPS_Module_3S

https://thepihut.com/products/ups-module-3s?variant=42418559647939

~$22

You provide your own set of three 18650 batteries, and it will output 5V @ 5A, plus 3.3V @ 300mA. Reviews indicate success powering a Pi 5. It gives you battery information via I2C. Neat.

Me, I'm just sticking with my Pi 4. It runs my cone-recognition model adequately, and it's a lot less of a hassle to power.

Interesting.  They also make a 4S.

3x3000mAh = same as Zeee 9000mAh LiPo with ability to charge in-line.

Can hardly be called a "hat".  

Wouldn't even fit the mounting screw pattern as a "seat cushion" but might with some drilling.

Has anybody tried it?

I guess the red/black/yellow wires coming out the back to the GPIO pins are for monitoring?

Or as alternative power input to the USB-C cable as they come off the expansion header?
