Hi everyone,

I'm looking for a suitable battery to power a Raspberry Pi 5.
I need something reliable that can support stable operation, ideally with options for portability and decent runtime, rechargeable.

Does anyone have recommendations for battery packs or power solutions that work well with the Raspberry Pi 5?
Any insights on capacity, voltage requirements, or specific products you've used successfully would be greatly appreciated.

Thanks in advance!

Try one of those "phone charger" batteries. They provide a USB connector with stable 5v and can store a lot of energy.

I have one of these in my workshop and I use it as a simple 5v battery, I have two Nucleo boards connected, powers them for many hours.

 

I have not tried it yet on a Pi-4. I have a USB Battery that has a USB power in and a USB power out.
When I use it for my phone, it will charge the phone on its own, but I often use a charger to charge the battery and the battery to power the phone.
It will keep my little half sized Pi running for hours. I don't know if it will power a large Pi. Wrong picture but something like this.

I agree that a 5V USB power brick would be the most convenient because no battery is going to provide 5V without some work.

Capacity needed depends on your application. raspberrypi.com says 5V @ 5A.

 

Welcome to AAC.

The RPi 5 requires a high peak current. Whatever solution you choose it will need to provide 5V@5A (25W),

Unfortunately, while USB PD is an attractive option, the fixed 5V options offers a maximum current of 3A.

All Is not lost, though—PD offers a mode call PPS (Programmable Power Supply) which allows for fine-grained selection of voltage and current. For example, the Anker 737 can provide 3v3 to 21V at up to 5A. But, in order to use PPS, you need a trigger capable of doing it.

A trigger handles the negotiation with USB PD, asking for one of the fixed voltages and a current limit, or—as you need—it can use PPS mode to make an arbitrary selection within the limits of the supply.

Triggers that can handle fixed voltages are dirt cheap, PPS, on the other hand requires more sophistication and so will cost more. A good option is the Elecrow PicoPD, which incorporates a RPi Pico.

Alternatively, you could use a higher voltage battery—such as a 14.4V Li-Ion pack of the sort used in RC applications (or anything about 9V and up) combined with a buck converter capable of delivering 5A (most small, cheap ones can't). They are available, though.

Whichever solution you choose, be sure to test it throughly to make sure there isn't any sort of startup overvoltage that couid damage the RPi.

 

maybe i wasn't clear, i am looking for something small, like phono battery (but its cannot supply 5v without boost).
I saw this:

Since the RPi 5 requires 25W, a smaller battery will have a very short runtime.

If you have some special application where you will be managing the power and so be able to use a smaller battery reasonably, you will have to build it yourself and most post includes basic information on how to do that, like that are doing here with a 14.8V battery made of 18650 cells and a buck converter.

You would have to use small, low capacity cells, like Li-Po sack cells or 14350 Li-Ion cylindrical cells (AA sized) and a buck converter that can handle the 5A peak. It would only power the Pi for a short time, though,
