Is there such a thing as .....?

A portable, rechargeable, power supply for pedals? Like, so you could use them in an outdoor setting more easily? I'm asking for a friend who wants to busk.

Yes.

There is a joyo or something one too. There was also one by Sanyo (Pedal Juice) I think that MF was giving away with Boss pedals (I think it is discontinued)
Also, there are pretty easy schematics on the internet. https://mike-bland.com/2013/01/11/recha ... upply.html

Dang beat me on pedal juice

Could probably use like black and decker/dewalt/ryobi tool batteries (9.6v ones) and make an adapter.

These guys answer "yes" to a pretty hardcore level: http://www.vguitarforums.com/smf/index. ... n#msg96962 You could do some pretty intense boards off of some of the battery packs they discuss.

the batteries that do DC output are called laptop batteries.

i have one by ravpower and another by tekkeon that have selectable voltage and was about $30.
battery life is insane (like 16+ hours running a synth or sampler) and it was much cheaper than the devices they market specifically for pedals (cough pedal juice cough) at least last time i checked.. they come with a bunch of different sized plugs.

since they are made for laptops they are positive center polarity. so i just stick a reverse polarity one spot adapter on it and now i've got negative center plug.

its come in handy a lot.

I'd say the Volto. I was gonna get one as it has had my attention since I switched to a PT-nano. Never needed it through because I daisy chained everything and use my tuner as a power brick.
