The Ripcord was sold out when I went looking for a solution a year or so ago. I prefer your solution to mine!

Ended up with a cheap USB power bank capable of 5A current (https://amzn.eu/d/jdfMPtF) + a cheap USB-C cable + a MyVolts USB-C to 2.5mm 5v to 9v Step Up adapter (myVolts USB-C PD Step Up Tip, 9V c-ve 2.1mm/2.5mm) to power the Stomp. Works great, though it has to be plugged in to each other in a...

Same for my standard Stomp. USB power for the win!

What did you end up using for the EQ system for the magnetic pickups?

The Everse 8 I can see being ideal for DB. It’s a great unit and the mixing capabilities are incredible. I thought the EQ and the presets were incredibly helpful. And there’s no beating the carry. The Goodwood definitely doesn’t run on battery, and it’s a very bass-specific rig. It needs a...

That’s great! It sounds perfect for you. I just sold my Everse 8. I just couldn’t get out of it what I needed at high volumes. It was really too much of an ask for a little cabinet. Plus at high volumes I heard a lot of resonances. I’m awaiting an LFSys Goodwood 10” cab now.

Simply FYI. Bluetti came back to me about their AC2A power station, and this has 3% THD for the sine wave AC power. So it looks like Jackery, then Bluetti, have the best THD figures for their AC power.

Another thought. I wonder if these sorts of power stations are primarily designed for 120V/USA market, and then adapted to work in UK/Europe/230-240V. @Wasnex your reports of the noise from your Jackery are quite different to mine. Perhaps the voltage differences mean designs that act...

Hmm. That’s an interesting thought. I just checked. Both the Allpower and Jackery units have ground lugs at the AC socket. And both behaved better when I used the shielded cable. I don’t have a convenient way to ground either unit, so I haven’t tried that either. I’m just glad I managed to...

....or maybe I won't try out another unit...Jackery just offered me 8% of the cost of the unit back and a free carry bag if I'll keep it. Hmm...

Some further feedback. (TLDR version - try buying a shielded power cable to connect an amp to the mobile power station.) I ended up ordering a Jackery Explorer 300+ to try out against the Allpower SS-005 (appears to also be known as S300). Jackery responded to me that the THD for the AC sine...

I think you’re right. I googled it further and it doesn’t do any active power conditioning. Mostly surge protection and EMI/RFI attenuation.

I also found one of the threads talking about portable power sine wave AC noise. https://www.talkbass.com/threads/advice-busking-pure-sine-wave-power-bank-noise.1486040/

That’s a really helpful @Wasnex , thanks! I have no intention of messing with homebrewed grounds and whatnot, I have no idea what I’m doing. I emailed Bluetti, Jackery, and Ecoflow about some of their models to ask about THD spec for AC sine wave power, after looking for suggestions from...

Further update. I have hit a major snag with the Allpower SS-005, which is that as I turn up, I get a high pitched buzz noise coming through the system. It doesn't seem to be from picking up noise from nearby devices (I tested far away from electrical sources.) Touching my strings etc makes no...
