Rechargeable Battery/Power Banks?

[ian_dissonance]

I didn't try that brand but I did try a couple of other cheap cable options with limited success.

I forgot to mention, maybe not ideal for your setup with only one device, but there are power banks with AC outlets now for $60 give or take on Amazon. You could plug a regular power supply into one of those and power an entire board for less than the Mission device, which is why I haven't tried the Mission.

I was looking at those, too. I’m trying to avoid “boarding” my floor modelers and part of the appeal is getting rid of the awful PSU Boss supplies with their modelers these days. That thing feels like it belongs to a store-brand kid’s toy.

It has 0. That's the device you plug the battery in to, it negotiates with the battery and then outputs to a traditional barrel connector for your pedals.

O I C. But then that's gonna become more complicated than just buying one of, say, those HB powerbanks.

I've done several gigs with both a Nano Cortex and a Tonex One, powered by my Anker Laptop Powerbank

What size Temple Audio board is this?

The Anker stuff in general is pretty decent (son 1 has a boombox that beats my Bose Mini by quite a mile, at 1/8 the cost) - so, what are you using for up-charging to 9V? And have you done some daisychaing with 9V pedals, too?

All USB-PD via the USB-C ports. No 9V.

Oh, I missed that it's a Nano Cortex, not a Quad.

Sorry, I’ve been out of town and mostly AFK. This is indeed right up my alley, and I’ll report back with details ASAP - though by then the OP may already be resolved…

I see you already found a solution for 9V Roland, so I'm not sure whether this will be of interest. But yeah, I've been obsessed with making rigs battery-powered and/or fully wireless for about 20 years now. (This all started with laptop builds, which include rechargeable batteries pretty much by default.)

My approach with my recent QC build was to simply find a laptop battery charger with suitable outputs. This one is, sadly, no longer available, but I imagine there is an equivalent or better by this point:

The QC is unusual in that it demands 12V rather than 9V. This supply provides that voltage, on its own dedicated barrel jack connector, at up to 3A. So all I need is one (polarity-inverting) cable from the battery to the QC, and I can use the battery's soft power switch to power up and down. I tested the board when I first built it and it ran something crazy, like 17 or 18 hours, on one charge. Plus you can charge the battery while the battery is running the QC without taking anything apart. Very convenient.

Watch out for "devils in the details" - like this one powers up instantly, but you have to hold the button for 3 seconds before it powers down. That has saved me from losing my work, oh... about a million times now.

It is pretty heavy, but under a Gator board, it doesn't add anything to the footprint:

That is slick. Any chance the battery could have caused your issue or was that not the same unit?

Thanks!

No, the "desktop unit" that failed was on the stock Golden Profit power supply, where it had been working perfectly for a couple of years. The one on the floorboard has also been running rock solid on the MAXOAK battery since I bought it. Not sure what went wrong with the desktop QC when it finally did. Restoring a backup on that one right now, and then I'll probably draft a "thank you and by the way any idea what happened" email to NDSP.

P.S. I do have a suspicion that a different battery - a BoxKing BK01, IIRC - might have killed my HX Stomp when it ran too low. But that's pure speculation; Line 6 never provided any feedback as to what part(s) had failed or why.

Since 2021, I’ve been powering my HX Stomp with a Mission Engineering 529M and an Anker Powercore 10000 Redux. I also needed a Onespot polarity inverter cable, but that’s specific to the HX Stomp. The 529M is can be adjusted to 6,9,12,15, or 18V.

I need to check to see if my Anker power bank is affected by the last recall, but my set up has worked well. I got about 3 hours of backup the last time I measured.

The USB-C jack on the 529M is a bit sensitive to movement. I occasionally need to reseat the USB cable if I am powering up. I disconnect the USB cable on the battery side typically, which might bump the 529M side out of its preferred alignment. I’m not sure I can trust it in a gigging situation.

I still have my Boxking battery. It's currently being used to power my Roland microcube (velcro'd to the back of it) but it was the primary source of power for my HX Stomp (sans wireless) board for 4 years.

I've had my BK battery die on me several times when powering my Stomp with no ill effects.

Probably just a coincidence, then. I can't say for sure whether the BK had even run down. The HX Stomp caused a deafening "pop" when it croaked, so I took it out of my amp's FX loop (who knows, maybe the amp was the problem) and set it aside for a while. I didn't realize until weeks later, when I got around to testing, that it (the HX Stomp) was dead for real. Bummer.

Similar shot of my QC + MAXOAK board. The power button is just to the left of the 20V output:
