Seems that question stumps many an online music store .

I will return to Hawaii , there are many who live off the grid there , there are opportunities to play some cool venues off the grid .

Burning Man and others here on the mainland too as well .

I have a DC self contained P.A. ( stereo @ 150Watts RMS a channel ) and want a looper that can handle my needs .

I need stereo in puts , mic , and preferable at least two tracks to loop on , three would be ideal .

There's got to be one out there.

:-\ Anyone out there got this covered ? :-\


I want to get  away from hauling a big 12VDC battery to run my P.A. and stuff , that's why I got the MAckie FreePlay . , the Roland uses one small motor cycle 12V DC battery and an inverter .

The boss rc-20 looper runs off of batteries. You'd need to find a used one. Also there are  lithium-ion battery packs out there that will start a car. And of course the rc300 loop station has the wall wart to convert to dc.

The RC 300 runs on DC volts ?

Yes. Most if not all of the pedals run on dc and lots of rack stuff have the ac to dc wall warts.

there is some gear out there that has a wall wart that is ac to ac such as my peavy midi streamer that has 16.5 vac in.
just be sure to check the volts and plug polarity configuration if you're not using the factory power supply.

i generate my own home electric power also.

I use a 5v to 9v converter and a battery pack.

I had to reverse polarity of the 9v output for my pedals but that was easy.
I use this battery but most would work for your needs. Larger capacity = longer usage cycle between charges.

For reference, last night I used this setup with 5 guitar pedals that draw approx 100ma each for about 4 hours and also recharged my iphone 6 from dead to 100% and it still shows 75% capacity left.

The Poweradd pilot pro already has a dc voltage  out that can be assigned for 9V,12V operation and can run an RC-300 with a polarity inverter adapter cable

I love not having to worry about ground loops or AC power to the front of the stage. I have done two gigs and charged my phone and still have plenty more juice left. My total investment was about $50.

That sounds hip .

What gear are you performing with . and what is your power source ?

This is the battery. https://www.amazon.com/gp/product/B012NIQG5E/ref=oh_aui_detailpage_o01_s01?ie=UTF8&psc=1
This is the adapter. https://www.amazon.com/gp/product/B01ID90E3C/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1
MY pedal board currently contains A boss tuner pedal, A Biyang Baby Boomer(tube screamer clone), a BYOC Large Beaver (big muff clone), TC Electronics Alter Ego Delay, TC Electronics Corona Chorus and a TC Electronics Allstar delay.
I am playing a stock '96 American Stratocaster and a Hughes & Kettner tubemeister 36 head with NOS pre tubes. Black plate RCA's in v1 and v2 and Telefunken in v3.

Thank you very much that's a slick light weight solution , there's so much catching up to do , input like your's is very helpful and appreciated .

Today I'm debating, Boss RC 300 or a TC Helicon Vocal Live 3

The next quest for my lightweight traveling set up is a small battery powered sub woofer to compliment my rechargeable  P.A.

Thank you again for that info , it's going to run the GR33 I play and which ever of the two mentioned loopers I end up getting .

IF your devices need center negative poswer you will need to reverse the polarity of the batter output. This can be done with an adapter. However, I simply cut the converter cable and resoldered it with reverse polarity.

Elantric or Anyone,

Ever had problem with the xtpower 32000mah mp-32000 not charging after initial charge?  Leds will not flash, nothing happens when using charger.  verified adapter working 19v output.  Help?

never had a problem in 2 years of use

But I never let it run flat  / dead - important aspect to know with Li-Po battery packs

Try this:

1 ) disconnect everything -


2 ) now connect the official charger that shipped with the power pack ,and  let it charge 24 hours

Tonemasterus

Ok I will try that.  When you plug in the charger does the leds flash for you?

Thanks

Left it on charge for 24 hours and nothing happened did not charge!  Guess I got a faulty unit?

also when not in use - i must physically disconnect it from the load for it to turn off. (i.e = must remove all cables except the charger connection

Had it less than a month. Didn't let it run down. It still had 80% on the meter.  I was just trying to get a full recharge before trying on a gig.  It works great as far as powering pedals, had my whole board running for 4 hours then went down to 80%. My concern is if it will recharge or not and I am almost up on my amazon return period.  Sent email to xtpower but no response!  Might try another one.

I would return it


but I'll post this for  those experienced with electronics who seek to revive a dead Li-Po battery pack
