I use an USB battery for powering my Zoom A3 and Ditto X2 looper exactly how it is described in this thread. In addition to that, am building an adapter with that converter for powering up a Cool Tube preamp in my Takamine guitars from USB, primarily for practicing at home and not changing AA batteries all the time. |

Excellent idea. Thanks! I picked up a cheap power bank at Aldi's the other day. Now I have a new use for it.

- Buying from the MyVolt website costs twice as much with shipping from France as ordering the exact same part on Amazon with free shipping. Of course I figured this out after ordering one (sigh). That and the MyVolt website might be the single hardest to navigate bit of code I've yet to see.
- The MyVolt converter provides 9V to a tip positive barrel connector. All of my effects (TC Electronics, Electro Harmonix, pretty much same for everything mainstream) are tip negative. - Does anyone know of a USB battery to 9V tip negative barrel converter? There are converter cables available but planning to send the MyVolt back (the text said tip negative.. what they sent was described as a power supply for a Vtech training tablet. Hmm)

Just for information, Mischief, you mention getting a 12V LiPo cell, such a beast does not exist natively as LiPo cells have a nominal output of 3.7 Volts (which is why power tools employing them have odd voltages like 14.8V or 18.5V) any configuration of cells has to come out at a multiple of 3.7 so you could get 11.1V or 14.8V. I'm not sure if an inverter would be comfortable with 14.8 (a car battery, when the engine is running sits at around 13.8V so the inverter may be happy with that) and 1.1 would be too low. Any LiPo power pack (like the Anker one mentioned above) needs either step up or step down/VR mechanism to get our usual 9 or 12V (or 5V for USB charging too). I imagine the Anker PP uses a step up voltage converter which would allow the same tech to be used for all the three voltages it can supply.
HTH BTW, i I've been trying to get my Anker PP to power my Roland AC33 via the line wart 12VDC socket (as opposed to the battery connectors) without success. No problem with my other kit though. I may try it with an inverter just to see if it's doable but it's probably not a practical solution and a mid sized LA gel cell would make more sense in that application.

My Fluke says it's 9.39V. Center positive.

This is the exact part I received from MyVolts. Am now powering a few Boss pedals with it now on various boards. |

Thanks Bearclaw.. good to know the right part exists. I ordered from them based on the product description which was center negative. Apparently just one of those mistakes in shipping that are going to happen from time to time. They haven't responded to my email yet so we'll see.

I just checked - mine shows center negative as well. |

I suppose if you ordered one of these and it was center positive, you could remedy with one of these:

Now we can power our pedals with inexpensive, rechargeable smartphone power banks
Thanks for the thread. I've ordered an Anker battery and a couple 9 volt adapters. Should be a fun experiment 🔋

I found another great use for this is to supplement the batteries in my zoom h2 recorder. I like to mount mine on a mic stand to be able to record and hear how things sounded from FOH, especially when I'm running my own sound. Seems like I always have trouble finding an outlet where I want to place the recorder and the batteries don't have enough juice to get through a 3+ hour gig.

Denmalley,
Great idea. I never thought of that. I just started to use a looping pedal at the end of my chain prior to the speakers I use. I wanted to record a complete song during sound check, to allow playback where I could walk out and hear what everyone else does. I never thought of using a zoom recorder for this purpose. Where do you place this device? Yes, I can bet this battery pack would be a perfect fit. |
