Portable Battery to Power Elektron

subduct · 2021-07-28T14:06:19.739Z

So not quite on topic but this is a bewildering subject!
Want to take my SP-303 on a camping trip next week. Got a case for it and a shedload of samples plus a field recorder. Now I need power!

SP-303 takes 9v DC 1000mA tip negative. Assuming it’s regular Boss 2.1mm barrel.
What power bank and USB>DC cable would I need - one of the ripcord ones?

How did you plug this amount of gears on it?

fffiiissshhh · 2022-04-28T18:41:19.720Z

Simple power strip:)

However in the future I want to figure out DC power for the entire rig. Converting to AC and back to DC is inefficient and very bulky (power strip, cables, PSUs etc.)

kpdp · 2022-04-28T18:45:18.702Z

I don’t really understand how you plug your gears. For example, how did u plug the OT and the H9?
sorry i’m just starting to dig into power bank.

fffiiissshhh · 2022-05-02T08:57:57.115Z

I used the included normal power adapters plugged into a normal power strip.
The battery has an AC outlet like you find on your wall at home.

can you recommand me a powerbank for 9V 1A? this is for synth, delay pedal and my soundcard.

Anyone know what the power draw of the Rytm mkii and Four mkii is? I have six outlets available on a Cioks DC7 that outputs 0.5ma at 12V per outlet so I‘m wondering if 1.5ma at 12V would be sufficient…thanks!

I just received the new Sandberg All-in1 Laptop Powerbank 24000. I have 3 Elektron devices that require 12V at 1 or 2A and it should be possible to power all 3 at the same time (potentially even up to 5!). There’s a 2.1mm DC out port that support 12V at 4A, so with a DC splitter and 2.5mm adapter you can power two Elektron devices. The two USB-C ports support PD at 12V/3A each. And the USB-A supports 5V at 4.5A.

It also has power through ability, so if you plug it in, it will provide ~45W to the power bank and assuming your devices connected use less, keep the power bank topped up, so it can serve as an 2, 3 or even 4-in-1 power supply for your devices as well (you do loose either the DC or one USB-C port when in power-through mode).

So you should be able to use up to 5 12V outputs at the same time - if you get a DC splitter cable, a pair of Birdcord PD USB-C -> 12V adapters and one USB-A to 12V converter (Birdcord or Ripkord) you’re looking at a total of 5 Elektron devices!

All this is theory, as I’m not sure if it can distribute enough amps at the same time on all ports and if the power through works as well as I hope, but I’ll be testing with my OT, ST and DNK once I get the DC splitter cable I ordered and report back here if anyone’s interested.

Okay, this is more or less OT MK1 specific, as OT MK1 uses a 6V/3A PSU and that makes it hard to find a solution, where as the other modern Elektrons have more plentiful solutions already available.

This looks to be a possibly great solution:

Some screenshots of the promo video shows the output DV voltage as programmable in increments of 0.1V, and starting all the way down at 3.3V.

I’m pretty happy with my Raptic TitanAC outlet battery, but it is much bulkier (and requires the OT PSU) so this might go in my Christmas wish list.

Hey.

How was the Sandberg? I was also thinking of buying this to power my ARmk2.

thanks!

[I don’t recommend this any more. see below]
I highly recommend this INIU 25000mah powerbank + birdcord PD 12v for any fellow European folk who don’t have a huge selection of banks to choose from (amazon won’t deliver batteries to my location).

this bank + cord is the bizniz. PD on this one delivers 3A @12v. perfect for the birdcord. cost around €50 delivered direct from iniu.

[EDIT: I was getting lots of crashes with this so I’ve stopped using battery packs altogether. not sure if it’s the battery or birdcord]

richie · 2023-10-04T20:11:30.456Z

Did you figure out if the crashes were from the external power?

pidgeo · 2023-10-04T20:30:12.037Z

yea, haven’t had a single one using the elektron psu. I don’t have another power bank to test so unsure if its the bank or the cord is the issue.

Blasted_pingin · 2023-10-04T22:08:56.531Z

I only use batteries with a 12V DC output. I would not trust any USB port to deliver peak amperage.

Blasted_pingin:

That’s kinda reasonable, because the USB spec is way too loose in this regard.

Personally, I trust some reputable manufacturers if they’re generally known for consistently delivering high-spec devices. That list is small tho’.

Even better, makes the choice easier This thread is long since 10 years when a small list of reputable batteries could just be pin pointed at the entrance

Now I use an inexpensive Ultron power bank made in China for sale German along with a custom adapter cable from hi-fi components and this, in addition to portability, turned out to be an inexpensive way for me to improve the sound of my Elektron DIGITONE device. Loved him again!

Hey thanks for all the helpfull info. Sadly tge links are down. I look for a cheap solution for my machinedrum. Where can i find a small powerbank for that?ravpower still
one of the cheapest options?

I am from germany so i got 2 pin power cable with my md but there was a 3 pin uk adapter with it. I am total noob with energy so far i just took it from the wall. XD

For those of you into park jams (when it’s warmer outside), I just wanted to share my discovery. I was able to power up my Digitakt & Octatrack mkII using a battery used by the Soundboks portable speaker. That should provide 100wh, which is plently of jamming time. For the dc plug I used a small adapter to adjust for the smaller sized electron dc socket.

Bought this battery from GP but now I feel confused…

It has 3A but only for 5V?

So it wont power an Octatrack that requires 2A at 12V?
