Great question! Why don't you run yours underpowered (undervolted, brownout?) for a few months and let us know the results. If everything is OK, then - cool! If not, well - would be good to know.

i would actually prefer waiting for a less sarcastic answer. since i am not a native english speaker and not an electrician and do not exactly know, what damage a brownout can do to a device (wikipedia: undervolting/power loss). so i was hoping for an serious explaination and someone sharing knowledge

All I can tell you is that in my case the thermal cut out didn't cause any damage to my unit as far as I can tell, how that could affect the unit long term is another matter, the MPC one pulls almost 12w at boot and if you're doing anything more than really basic stuff regularly pulls 9w+ which is on the outer limits of what the ripcord can deliver, when doing that these things get hot and i mean hot enough to be uncomfortable to touch, do you really want a 600 dollar paperweight for the sake of buying a power supply that can comfortably handle the demands placed upon it? I sure don't hence the xt power, a ripcord and decent powerbank will run you about 35, I managed to get a 15000mah xt for 20 more, it's worth the extra believe me..

It sounds like you answered your own question. If you dont know enough about electronics and the effects of underpowering electrical devices, then why take the risk?

The Mpc one power supply and official docs say the One needs 19v and min of 3.4amps. The XTPower provides this exactly. So Why not trust Akai and get something that meets the specs?

I went with the XT and it works great. I personally always follow the manufacture specs on these kinds of things as I am like you, neither an electrician or expert on such matters.

thank you

so, i can and will return my ripcord cable even after the long time of ownership (thanks to thomann service). while some people with knowledge here refused to explain exactly, what danger can come to our mpc (brownout), the risk is valid and there and of course there is explanation online (random link, still basic).

unfortunately i can not edit my recommendations of the cable here in all the posts, so may this help as an update.

i also will contact ripcord to ask them to remove the compatibility info for mpc one on the cable.

so thanks everyone contributing and warning, this was actually helpful. i will stay with my ac-output powerbank, so the original power adapter from my one can deal with all the possible power instabilities caused by whatsoever. even prefering this over the recommended xt-power power bank here - i do not trust random china products with direct power adapters so much...

I dont think people here are purposely withholding information about the effects of brownouts on the MPC's. The only people that would know the effects are either Akai engineers or someone who has put their units through a series of brownouts.

And fyi, XtPower is not a random chinese company. Simple google search shows its a subsidiary of
Juanch. Here is what this site has to say https://www.accesswire.com/432295/World ... -Agreement

About Jauch:

The Jauch group of companies is one of the major specialists in quartz, oscillators and battery technology. The internationally operating enterprise, established in 1954, is a key player in the pulse generator component segment and, with the recent addition of innovative MEMS timing pulse generators, is a proven expert in the future market for lithium-ion and lithium-polymer battery packs.

You can also see on this site that they provide parts/batteries to pretty much all major industries. Personally, I feel confident that my MPC One will be fine since they supply hospital equipment, aeronautics and military.

Of course, everyone is free to make their own choices. Just wanted to comment on the notion of them being a random china company.

well, we are going offtopic a bit, but i keep it short: sorry, i disagree. a brownout is not a phenomen which only happens to mpc one, that's what i learned already. and those, who warn about damage, should (and probably do) know more than "it's just not good". even that would have been an answer, but "if you don't know a), you don't deserve fact b)" is just toxic behaviour. don't answert noobs, if you dont' want to help. period.

thx for your input consider me overcautious, everything comes from china, even parts of the mpc (i guess). why i still hesitate (and this is no critisim): your link leads to a webpage in a pretty strange layout, claiming Juanch is a trustful company. and talking about a brand bought by another company selling brands unter a name... i don't know accesswire - it's not a popular or well known reference for something in europe. so i am not smarter than befor, sorry and again: no offense! one can buy this powerbank after good reviews here, i just don't do more testing and stick to my a/c as long as it runs (2 years maybe).

greetings

Just give me MPC Live battery pinouts and I make cheap MPC One internal battery

brownout is not a phenomen which only happens to mpc one

You asked specifically about the effects of brownouts on the MPC.

while some people with knowledge here refused to explain exactly, what danger can come to our mpc (brownout)

I am merely pointing out that the people who are trying to give you advice (so you dont cause potential damage to your MPC) likely dont have that information and if there is someone with that information, it would be either Akai engineer or someone who has put their MPC through a series of brownouts.

If you want to know the general issues caused by brownouts, then an electrical engineering forum might be a better place to find such information.

and those, who warn about damage, should (and probably do) know more than "it's just not good". even that would have been an answer, but "if you don't know a), you don't deserve fact b)" is just toxic behaviour. don't answert noobs, if you dont' want to help

This logic seems strange to me. So you mean that people who do not have first hand experience should not try to provide advice that certain actions can cause potential damage?

I would never get in a car with a drunk driver. I dont need first hand experience to tell me its a bad idea. I would warn anyone wanting to get in a car with a drunk driver that its a bad idea. I dont have first hand experience of being in an accident with a drunk driver but I believe the advice to be good.

What pinout information do you need? Is it just a pic of the internal power connector?

I am not sure I will be able to take mine all apart but just curious

uhm... yes? of course?
provide, or shut up. what else?

Hi, I am a retired electronics/computer tech, with a great deal of repair experience.
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

I got a ripcord to use my MPC One on the train during my commute. The MPC booted up fine, I could mess around, play all the demo projects, etc. Then, I started a new blank project and started browsing Hype presets. After a few one, just as I was about to lay down a chord progression, it shut down. Must have taken about 10 minutes max. So, I'm returning it. I don't think it would damage my MPC but it's really unacceptable that they say it's compatible at all!

I unfortunately was unable to find any XTPower XT-20000QC3 online that I could order in Canada. So I instead ordered an OmniCharge Omni 20+. I'll use it with the built-in inverter at first but will investigate using it's DC output, which has a configurable output voltage. The Omni will also be super useful in the summer on the sailboat or camping.
