I credit this thread for putting the idea in my head. It was a great idea, based on one 2-hour test (so far)For less than half the cost of that NOMAD jawn FM four\_oclocker\_2 linked to, this setup:- uses a 5v USB battery that can also charge your phone/headphones/small sex toy- includes a standalone power supply that'll plug right into the wall/your old amp with the AC receptacle- is quieter than any daisy chain I've used with these pedals in this order (also quieter than the switch-mode AC-DC converter that came with the isolated power supply)I probably won't ever get the chance to plug an amp into a generator and play electric music off the grid. But I was so happy with the portability and low noise floor that this is going to be my outboard setup for the foreseeable future.I used:- a 5v 10,000mAh USB battery - a 5v-12v step-up converter USB to 2.1mm barrel plug cable https://www.amazon.com/dp/B01G3ERI6U/- a power supply that uses a 12vdc tip-negative connector to connect to external electricity https://www.amazon.com/dp/B015X9E4VI/- a polarity-reversing adapter https://www.amazon.com/dp/B004EBG5QE/Caveats:- Reviews of that step-up DC-DC voltage converter suggest it's only putting out ~600mA at 12v. Worked perfect with an OD, fuzz, tuner, wah, and Rotovibe, probably can't hang with a fancy new modulation computer-type pedal + a bunch more power-hungry stuff.- I confirmed my assumptions/reading of labels regarding voltage and polarity with a meter before plugging in $$ pedals because I'm always on guard against my own stupidity- If you don't have enough draw (i.e., you turn off every pedal to play a squeaky-clean verse), the battery I used will turn its output off. I had to get my meter set up and turned on before plugging the USB converter into the battery because the converter itself doesn't draw enough to keep the battery outputting power.- That's not the exact power supply, I can't find the one I bought online now. If it uses a 12vdc tip-negative connection to the wall, I think it's interchangeable for this purpose. (Hopefully the Vitoos one I linked to comes with a quieter wall wart than the one I actually have) - If I didn't already have that polarity-reverse adapter, I would have just cut off the barrel connector on the step up converter and swapped the 2 wires. That's how cheap I am.This whole pile was less than $100 incl. shipping, and almost half of that is the power supply that will come with a wall wart of its own. So if you're just using daisy chains or batteries and are considering getting a power supply, one that uses a 12v input to generate its 9-12-18v outputs can also be used this way, for only an additional $40-50. And wow is the battery quieter than the wall wart mine came with (not the Vitoos I linked to, the one I got is so no-name I can't even find it now). This is going to be my pedal power solution for the foreseeable future. Thanks for the inspiration.
