I used to work as a wireman for Rockwell Automation...wiring up power circuits was one of my specialties. I used to wire up 1000 horsepower motors to computerized assembly line control circuits for motion control systems...wiring up a few foot pedals is a piece of cake for me.

With a mid-sized pedal board I'm pulling too many amps for this solution but I still really like the idea. I had a Pedaltrain Volto for a portable setup but the connectors failed rather quickly rendering it useless. Think this rig would be better overall.
And things will only get better. Thanks for sharing. What a great idea

How long you can power the pedals depends on what capacity battery you choose, natch... mine is on the small side at only 6,400mAh, because I wanted to go really small. You can get models from the same brand with varying capacity up to 20,000mAh or even more. I need to do some more testing, but I think it's safe to say that I can get at least 15 hours. You can almost ignore the tuner, since you'll only be using it for a minute now and then; the Ditto may be more of a power suck, but you can research what it and the chorus draws (or measure it with a multimeter if you know more about that stuff than I do!) Besides capacity, the other thing that matters with the batteries is output. I doubt your pedals would draw more than the 2 amps (2,000mA) that mine puts out, but if necessary you can get larger models with 3 or 4 amps. Aloha! |

Your situation my not be so hopeless... what is the total power requirement of your pedals? Some common pedals, like the BOSS GE-7 Equalizer draw only a minuscule 7mA. And although my little battery only puts out 2 amps (2,000mA), other models put out 3, 4.5, maybe even more. |

TC Elec Flashback X4 - 300mA TC HoF - 100mA Empress ParaEQ - 100mA Joyo American - ~10ma Much of these are superfluous toys to screw around with. Only really use the TC HoF and ParaEQ so if I were to set up a mini-pedalboard I could get by for 2-3 hours on a $20 670mAh battery. Bring a spare and swap after the second set and should be good to go. Thing is I already have a Pedaltrain set up with a Voodoo supply so things are wired for now. Still.. a good future project.

Inspired by TS, I did some additional research. It seems like there are powerbanks in the market which already has a 9v output with 2.1mm plugs. E.g:http://www.amazon.com/Anker-20000mAh.../dp/B005NGLTZQ
Can these be used or do I have to worry about the center negative/positive issue? Really like TS' solution but it will cost $30 to get the USB-9v cable to my side of the world |

With some time based effects, the current draw can be pretty high. Boosts, eqs and the like are usually much less. That and some pedals really don't like to be daisy chained and can be real noise generators. I have used a chain and gotten good results only to have the whole thing become unusable when I added a specific pedal. Still a good idea and if it works for your system then you are golden. hunter |

Googled the cable for pics on the web, and it seems like the max output is 6.3w. Which means that at 9v usage, max current output is 700ma. Not too bad actually. In terms of practical use, most power banks come with 2 usb outputs, so with 2 cables, you can run 1400ma worth of pedals I believe. In an even more extreme scenario, you should be able to use a USB hub and run 4 cables concurrently.
Hope I understood this correctly. |

Whoa! Thanks for the tip! I just ordered one of those.

I'd need to test out the reliability in person.
Right now I prefer the reliability of a proper power supply with isolated outlets. I use a Voodoo Labs Iso-5 at the moment. One plug for all pedals (was already using a wall wart for my preamp), isolated outlets so no added noise, and I can get the 18v required to boost the headroom of my preamp. |

Nice setup. I could use that battery idea in a pinch. Those Flashback DD's are nice. I could get away with just the 2290.

My myVolts adapter has 700 mA on the label rather than 350… but yes, that's much less than the 2A that the battery is capable of putting out. Plenty for my needs, though.

Update: I tested the battery endurance by running signal into the rig in my original post, and the battery lasted about 23 hours. The battery was powering the TC Flashback Mini the whole time, and I also turned on the tuner occasionally to better mimic real-world conditions.
