I have purchased and/or built many battery solutions for using my music gear away from AC mains power.
I am not, an AKAI MPC repairman, or engineer.
Introduction out of the way....
I have purchased a Ripcord usb adaptor for my MakeNoise O-Coast, and Strega.
The first one I ordered, never arrived, after long wait, I asked for them to reship.
They have good customer support, and sent out a replacement.
Shipping takes about a month+.
The unit that I received, was defective, as it would overheat, and smell like burning, then turn off.
Again customer support was helpful, and sent a replacement.
Of all the high current, usb battery packs and wall adapters I have, The replacement Ripcord adapter, only works with one.
Not a ringing endorsement.
Having read this entire thread, especially the power requirements for the MPC One, I would not recommend the Ripcord for this application.
Therefore I am purchasing, and would recommend, the XTPower XT-20000QC3 Powerbank instead.
I am purchasing from Aamazon, and can return if needed.
As far as "brownouts" or having the power fail, while you are using your MPC One.....
Products like the MPC, are fairly robust, when it comes to loss of power.
It is highly unlikely that the MPC will be permanently damaged by this (makes sense, when you think about it, right?)
BUT....you might loose any unsaved work. And it is generally considered a bad practice, to remove power from a data storage device, while you are writing data to it.
Though it is rare, you could end up with corrupted files on your disk/memory card, that might require reformatting. So always backup important files.
Without direct feedback from AKAI Engineers, this is the best advice/info you will get.
I hope this will be helpful to all, and especially to those, without a background in electronics.
Peace n Love, from sunny California

But from a local car equipment centered department store (Motonet) I found this car jump starter kit that has the perfect specs and connectors for the purpose: https://www.telwin.com/en/prodotti/?id=829566&lingua=E
Main thing is that it has dedicated DC out (19V, 3,5A) and comes with neat little 15cm long cable that fits the MPC perfectly.

Check it out here:

The converter cable is from Amazon (Aliexpress is an option but a longer wait), but there's also a vendor in Austria that sells them with worldwide: https://www.songbirdfx.com/products/birdcord-pd20v/
Comes with a markup on the price but also a nice pouch
Main thing is that the powerbank does actually deliver high wattage and supports the PD standard. The converter cable needs to be able to output 19-20V.
The rest is up to your personal perferences and what's available.
I'd recommend people stay clear away of 30,000mAh batteries if they plan to travel by plane, though. But if you're getting almost 10 hours of runtime on that 25,000 mAh battery, that's pretty damn impressive! I'm lucky to get 5 hours on my Live II (it's only 3350 mAh).

Your 25,000 mAh battery is equivalent to 92.5 watt hours, which is just under the 100 watt hour limitation that the TSA has on commercial airline flights in the US, so that's awesome.
Can you post a link to the exact 25,000 mAh power bank that you bought?

Good advice on the 30000mAh batteries! Yeah 10 hours is great for me, and the battery also charges quite fast from a 65w charger.
The exact battery I am using is this one:

And here it is again in action from the side

TBH I don't know what the trigger actually does or why its needed

The adapter is to convert the current from the external USB-C power source to match the requirements of your device.
It is also needed so that you get the right jack, as usbc won’t go in the MPC directly

Cheers, I understand re the requirement to get the right jack, but what does the 'trigger' side of it do? Given that the power banks can output the correct 19v anyway? Re converting current, does the MPC not just draw whatever it needs (up to the point that the bank is too small obvs)?

Right, I understand your problem now. What the trigger part does is tell the power bank to actually output current, since usb c is a heavily microchip controlled affair where the receiving device has to ‘ask’ for power delivery (which the MPC obviously cannot do since it uses a different power delivery system).
