Hi,
Is there a way to battery power the QC??? I want to use it busking outside, like on a street corner.
Any thoughts?
Power to the QC People
I’ve been using a UPS (an uninterruptible power supply designed for routers) for about a year now and haven’t had any issues at all. The unit I use can deliver up to 65 W, while the Quad Cortex draws a maximum of 36 W, so there’s plenty of headroom and I can stay unplugged for up to around 4 hours.
Another important point is that, here in Brazil, the power grid is often unstable and can be quite noisy depending on the venue. Using a UPS also helped eliminate that problem.
I started looking for this solution after a few gigs where people accidentally bumped into the power supply. At one show, the Quad Cortex took a very long time to reboot, which was pretty stressful.

To just power the QC the songbirdfx usbc to 12 v and a polarity switch cable work well with any usbc pd akkupack that has 65 w

Thanks for the reply. Those are cables; what is the actual battery that you use, if you would be so kind???
I use this pd battery at the moment

But you can use any pd battery with usb c and at least 65 w
I purchased a 300-watt lithium power generator from Amazon for $89 that recharges from a wall socket or a solar panel. It has AC, a 12-volt car plug, USB PD, and other outputs. It is very compact, pretty lightweight, and comes with all cables and a nifty carrying/storage case. It has been a rock-solid solution to have an off-grid QC set up when paired with a 10" Alto powered speaker.
Do you have a link? Thanks for sharing 
I can no longer find the specific solar power bank I purchased, but if you search for “solar power bank $60-$100,” you will discover many similar units that will meet your needs. If you pair it with one of many inexpensive solar panels, you will be good to go in any situation.
