that looks pretty perfect for either machine, let me know if you take the plunge!
Gaia.Tree Hi! Have you checked how long oktatrack mk l continuously (only when it is powered by this battery alone) works with RAVPOWER AC 20100MAH?
Hello everyone !!) This is Russian style))) I managed to find an excellent Gumo device in the open spaces of my city, this is an external battery with a capacity of 40,000 Ma, 12v / 16v / 19v different voltages are possible. 4 amps at the output ds. Two devices were able to work at a maximum of more than 3 hours. There were no overheating and failures. How long one device will hold in the future. To connect the two devices had to assemble a splitter âŚ

Hey all, is there any consensus on the best way to power multiple devices at once ?
Thinking on OTmk2 plus another box ( a4, akâŚ) and a soundcard for exemple.
Thx a lot.

Yes good evening Elektronaut 
itâs a question asked.
Elektron would be at the top of the market, if it would develop, a portable and mobile unit, which would power three elektron grooveboxes!

The best setup iâve found so far to power my Digitone or Rytm is to use an Anker-PowerCore-20100mAh portable battery, with a Ripcords 12v cable (model:AA928MS +adapter tip).
For the Rytm you would need a combiner cable to use both USB slots on the powercore for more juice.
Everything can be found on Amazon.
To get the cablefiddling fine and only use 12V to power everything, put stepdown converters in the OT, MD and MnM. Works fine. There enough place in the cases and the converters do not get hot, just warm. Putting thermal paste between case and converter helps.

Got 2 Ripcords 12v cables for my Digitone and my Digitakt!
I have this external battery : https://www.amazon.fr/gp/product/B06XCM8DZM/ref=ppx_yo_dt_b_asin_title_o03_s01?ie=UTF8&psc=1
but it seems to be not enough to power the Digitone, it freezes on the power-on animation. 
The Digitakt on the other hand is perfectly working, as itâs less demanding than the Digitone.
I wonder which spec I should look for to buy a USB battery that could power both units.
Hi, I picked up a rip cord for the octa mk2, do you know if this power bank would work ok?
Hey, do you know if this works for the octatrack mk2?
Bought a charmast 26800 and not working, poss cos of ismart tech.
Wondering if your anker has the âpower iq/voltage boostâ, as suspect this might be the same issue, perhaps with newer PowerCore versions?
Yeah itâs listed as having âPower IQ technologyâ, mine has been working perfectly. Iâm pretty sure The ripcords have all been tested with this exact model (Anker-PowerCore-20100mAh) so that wld be the best batt to buy.
Itâs possible that you might need two cables to power it, Iâd just message Myvolt directly they have great customer service and will sort it out for you.
Nice one, that helps a lot.
Ive got the extra adapter end for OT from myvolts.
Shame the charmast doesnât work, itâs a nice power bank.
Thanks
Anyone here used any of the current gen AC battery packs to plug the OT Mk2 in, with its PSU?
I had success with my old Ravpower AC thang , and now have a Jackery Powerbar. I am bringing myself back into OT land after a couple years and hoping this will work.
Here are the relevant specs
AC Output â 110V 85W
Minimum Output Current â 20mA~160mA
Whats the best option for powering OT MK2 & AR MK1 at the same time? also maybe a microfreak?

how about Birdcord for OT mk1?
https://www.songbirdfx.com/products/birdcord6v/
specs say âOutput voltage: 6V DC, peak output current: 1500mAâ
ot power brick says 3A but I wonder if that is real consumption�
Hey Man!
What is this combiner cable?
Want to power my AR with the Ripchord 12v Version. Itâs not working, the Ampere of the Rytm is to high
OK guys, hereâs a great summary guide for this as Iâve tested many battery packs now on my collection of 7 Elektron devices:
Machinedrum UW+ MKII
Monomachine MKII
Octatrack MKI
Digitone
Digitakt
Analog Rytm MKII
Analog Four MKII
In summary, your cheapest solution for all the newer 12v devices that is also TSA compliant and can deliver the necessary 2A for the MKII Analog boxes is the TalentCell 72W 100WH battery for $51.99 on Amazon:
This will power an Analog Rytm or Analog Four MKII via DC with no power adapter for about 2 hours and the Digitakt or Digitone for about 4 hours before the battery pack fails to output the necessary amps or volts and cause the devices to freeze or glitch. When this happens, the battery will still show about 75% charge capacity.
TSA laws prevent you from going on a plane with a lithium power bank of over 100WH unless you have advance airline approval. Donât buy one with a higher capacity than that if you plan to fly with it. Youâd probably get away with it but now and then you get a stickler TSA agent. Whatâs funny about this is that as far as I can tell, the laws do not specify the voltage for that 100WH rating, which matters a lot. Seems to me like legislators donât understand power which means TSA people are unlikely to understand it either.
With special advance airline approval you can take packs as big as 300WH. You can probably get away with taking a 300WH capacity pack on a plane if you just say youâre camping and need it for your CPAP machine, but you risk having to surrender the pack to the TSA if you just show up without advance airline approval.
For the older 6V 3A devices, the cheapest solution is an AC output inverter pack like one of the portable inverters made by RAVpower. Here is the cheapest one:
You can power one of the older 6V devices for 6-7 hours with this 72WH pack and a newer Analog MKII box for about 2 hours 45 minutes with it, so itâs definitely the cheapest universal solution but you have to use the Elektron power adapter with it, which makes it bulkier and a bit more awkward.
If you have both older 6V and newer 12V devices, and want the most efficient and least bulky solution that charges fast and is also TSA approved, the Omnicharge 20+ is the way to go. I couldnât find another battery pack other than the Omnicharge that outputs 6V DC which is a highly uncommon voltage. Plenty will give you 12V.
You would think that a higher MAH or WH rating on a battery bank would result in more runtime and that going direct DC vs using the AC adapter would also give you more runtime per WH because of efficiency losses coverting DC to AC to DC, but this is just not true!
The TalentCell 100WH battery, for example, gives me just over 2 hours run time with my Analog Rytm on direct DC without the AC to DC adapter but the RAVpower 74.37 WH inverter power bank used with the Elektron AC ot DC adapter gives my Rytm 2 hours and 45 minutes of runtime. Neither one specifies what voltage the WH rating is at, which may be another factor I cannot account for.
I believe this discrepancy has to do with the voltage regulation built into inverters as well as the Elektron AC to DC power supply.
The problem with powering directly from DC is that DC power banks without an AC inverter struggle to deliver consistently high enough amperage or voltage to keep the devices working normally across their entire charge capacity.
Iâm seeing DC battery packs without AC inverters stop delivering high enough amperage or voltage at 12v output to keep an Analog Rytm working without a glitch or freeze at anywhere from 20% to 75% of their indicated charge capacity. At full charge they will work but you canât use their full WH capacity because the amps or volts drop down to below what the device needs to operate when you hit a certain discharge level that is long before full discharge.
Conversely, any battery pack other than the Omnicharge with an inverter used in conjunction with the Elektron AC to DC power supply actually gets you more run time per WH simply because the power goes through several phases of transformation and regulation before reaching the device. This results in efficiency loss but the amps and volts remain more consistent as the pack discharges, allowing you to actually use the full capacity of the pack instead of a fraction of it.
So if you want the longest lasting, most universally compatible and TSA approved solution for the best price, get this one:
This should give you 4+ hours of runtime for $120ish with even the most power hungry Analog boxes and 8+ hours with the 1A 12V devices or the 6V 3A devices using the AC outlet with the original Elektron AC to DC adapter. Itâs bulkier and over 2x more expensive than the TalentCell, however, so it only makes sense if you want double the runtime for more than double the price and donât mind a lot more bulk and/or need a universally compatible solution. Two of these will give you 8-16 hours with any Elektron box in a TSA approved 100HW capacity and also power any 110v, USB or USB-C device.
A less bulky but more expensive solution that comes close to the runtime is the Omnicharge 20+ with a TalentCell 100WH backup to passthrough charge the Omnicharge while using it. This configuration allows you to power ANY device of ANY voltage requirement up to 2A uninterrupted from direct DC for 7+ hours (no power adapter) and all TSA approved as well with minimal bulk and cables. A lot of FX pedals and keyboards take 9v and the Omnicharge can be set to output any DC voltage so this works great with truly any device, even the Roland MC-707 which takes a wierd 5.7V or a Dave Smith Tetra which takes 15V to 18V.
Some devices like the Korg NTS-1 are very prone to line noise on their outputs from dirty power or interference. If youâre sampling or recording a mini synth with a Digitakt, Rytm or Octatrack, youâll want a separate power bank for each device. Running two devices from one power bank will get you buzz and hum.
And the Ripcord is a fantastic solution for any 12v or 9v device 1a or less, including the Digitakt or Digitone. You can run a Digitakt or Digitone for 2+ hours with a tiny credit card sized 5000mah $10 cell phone power bank using one of these Ripcords or use your laptop as a power source in a pinch.
The Digitakt is definitely the longest running, easiest to power metal Elektron box via battery and Ripcord and most portable of any of the metal boxes. But Iâm willing to bet the Model:Samples or Model:Cycles would be even less power hungry and certainly more portable.
As a tangent, nothing beats the 1010 music blackbox when it comes to pure portability and maximum battery power runtime. Not as deep as any Elektron but far cheaper and far smaller than most with up to 1TB sample capacity via microSD card and ability to sequence midi and both stream and record samples hours long, you can use it much more comfortably in a hammock or connect it to something like Modal CraftSynth or Roland Boutique and get more sound design power, though simplicity suffers connecting 2 boxes together with cables. It also has 3 stereo outputs which is great for any sort of analog mixing. Two blackboxes connected to a DJ mixer is like fitting 4 CDJs in your pocket that can also act like drum machines, samplers, portable recorders or MIDI sequencers. The Elektrons go deeper on most fronts but the versatility and portability of the blackbox for the price is unbeatable and it makes a great companion to any Elektron box, particularly the ones that cannot sample. Something to think about if you want the most portable, use anywhere setup currently availableâŚ

Everyone on here is awesome.
Talk to me guys n gals. I have a Machinedrum mk2 UW and a Takt and a Tone. I am looking for one battery that would power all 3 (independently) without the use of extra connections etc.
Bonus points for a display on the battery.
Thanks all.
