My Battery Powered QC Pedalboard

Yeah, if you get the bottom Krisdonia, you only need the Truetone reverse polarity adapter since it’ll come with the DC cable anyway and like you said it has the 12V DC out too so you don’t have to switch. I didn’t want that one as it’s bigger and heavier. The top one fits under my Temple pedalboard with some clearance, this one would probably poke out under it.

This (https://www.amazon.com/Volessence-50000mAh-Laptop-Portable-Charger/dp/B07RNZZXRM) might also be an option. It looks like a Krisdonia, like it might even be the same part, but I asked a FAQ question and they said this one does remember the last voltage setting. I didn’t try it though.

Yeah, the 12v DC out feature will work for me on that unit; and I returned all cables except the reverse polarity one. As soon as I get the refund for the returned battery, I’ll pull the trigger and get the new battery, and I think I’ll be set. They had to email me haz mat labels along with a shipping label since it has lithium in it; so it’ll take a few days ]m. It is thicker, but I think my board will conceal it if I keep it up top.

Hey everyone -

Hypothetically if someone were to use a USB GaN power supply (120W with enough juice to power a few QCs) with a USB-C to 12V DC cable ….

would it be an issue if there’s more mA provided than what the QC can take?

For example:

USB-C to 12V DC, actual output 3A
QC power requirements: 12V DC, Min output 1800mA

The other question is:

If said GaN- power has multiple PCBs for each USB-C PD slots (confirmed via YouTube teardown) is that considered “isolated”?

Could you hypothetically run another, say 9V DC for a Bigsky and another run 9V for analog pedals like drives?

What would you guys recommend getting in 2024?

Did anyone figure out why some chargers like the MacBook one produce low signal on the outputs when used with the 529m and more importantly which ones work?

QUESTION: Was the issue with the Anker (or generic) battery pack NOT booting up the QC due to the polarity reversal?..or due to the fact the battery didn’t supply enough amps?

FYI - there is a new product out called MyVolts StepUp - specifically for the QC; have you tried it?

I just use a regular 25000 mAh power bank with a 12v PD USB cable (DSD TECH MagicConn USB Type C PD to DC Power Cable-12V: Amazon.co.uk: Computers & Accessories)

and a polarity reverser (these ones are by far the neatest option, no cable attached, just slip over the end of the PD cable, and you can use heat shrink to hold in place if you want: 2.1mm x 5.5mm DC Polarity Changer Centre Positive Socket to Centre Neg — Switch Electronics | Your One Stop Component Shop)

Works perfectly, and I get about 6 hours of QC use from this set up
