I sometimes use the PO in front of a PC, so I was thinking adding a female micro USB port to it ( on the break away
hanger):
"MICRO USB to DIP Adapter 5pin Female Connector B Type PCB Converter"
I’m guessing the batteries are in series parallel, so it’s only 1.3v 3v, so just following this post
"LM317-DC-DC-Converters-Circuit-Boards-Module-Adjustable-Linear-Regulator-1-2-37V"
Any thoughts?
A fake 2xAAA battery pack with a trailing USB? Wonder if such a thing already exists?
Yeah, less butchery… good idea!
I’m now thinking just a normal USB male cable with the regulator and alligator clips!
the batteries are in series so it is looking for 3V (not 1.3V) cheers Paul
haaa… thanks for that… I was just about to order parts to
I’m preparing a hacking kit to do this, it will consist of DC jack for the PO, small power supply powered thru micro USB and a daisy chained cable(like the ones used for guitar pedals). With this you can get power from a USB wall wary, USB portable battery or batteries. Pic-> https://instagram.com/p/BNKL9s0A3FB/
Not USB directly on the PO but on an small outboard power supply. So kind of similar
I’ll be offering this kit thru reverb.com
I’m putting kits together at the moment.
@jn7 any chance a USB C or USB mini jack option will become available after launch? I’d like to share cables with op-1 or phone/tablet which share USB C. Great work!
@PLNB hi!
@PLNB a single power supply can give up to 800mA @ 3V assuming your USB power source being a a portable battery or wall wart can provide at least 1A. This should easily power 3 or more POs at the time using a daisy chained cable.
This weekend I’ll post pictures and video desmostrating the system and how it works.
@PLNB Hi, the kit for 3 is up in reverb.com along with a video showing how it works.

If you have any comments please let me know.

Nice bit of kit José. I’m not committed to soldering my POs until I have a 3PO case solution, but may prefer a clamp on power source to allow switching out POs or make use of the TE silicone case with minimal cutting.
Hi,
So I finally got the LM317 converter as mentioned and alligator clips and I put it on a long USB cable.
I’ve had the PO-20 playing back for 1hour or so, it works good, the heatsink doesn’t get hot.
The clips are okay, if not moving the device.
– Instructions –
It was pretty easy to do, no soldiering required
Cut the head of a USB cable (the non USB male plug).
With a multimeter, find the power and negative lines, better to use a power plug witch doesn’t output data signals.
With a small flat head screw driver (called precision screw drivers):
a: wire up the positive into the in port marked Vin and neg into Gnd
b: wire up the alligator positive Red clip into the out port market Vout and the negative black clip into Gnd
Connect the alligator clips to a multimeter and turn the blue pot screw (from memory I think it was clock wise), until it drops to 3v, I have mine at 2.97-9v
Connect to PO’s battery, for me the Top negative and bottom Positive worked.
As shown on my quick video:
Adding USB ot my Pocket operator PO-20 Arcade - YouTube
looks interesting…

The POs get a solder and glue on connector with another 2.1mm jack to plug into the USB power supply.
