Portable Pedal Power Supply

Hate plugging your pedalboard in with extension cables? The Mission Engineering 529i USB Pedal Power Supply gives you the convenience of running your pedalboard with no extra cords. This compact device can power up to eight standard pedals using its large, onboard Li-Ion battery. The 529i can be powered from nearly any USB device or the included wall charger. That means you can charge up on the way to your show, or plug your power supply in before bed. Have 18-volt pedals? No problem. The 529i includes a voltage doubler cable that uses two 9-volt outputs to power a single 18-volt pedal. To get the most out of your pedalboard, choose the Mission Engineering 529i Pedal Power Supply.

Plug in and charge from almost any device

Wherever you are, you’ll be able to charge your pedals. In most cases, you’ll simply plug the AC adapter into the wall. But if you’re in a jam, a little creativity will keep your show on the road. You can charge the power supply from a variety of devices. First, you can use the wall adapter and charging cable from your smartphone or tablet to refill the power supply. If you’re not at home, you can easily use a computer or USB battery pack. At Sweetwater, we found that the 529i can even be charged by your cars USB charging port! With so many different options to choose from, you’ll always be able to charge your Mission Engineering 529i pedal power supply.

Quiet pedals, happy amp

I purchased the Mission Engineering 529i in an effort to quite noisy pedals and it does just that. I was wall-wort/daisy chaining power before and pedal noise made my pedals almost unusable. This made my pedal train so quiet that I'm actually hearing all the nuances of the pedal effects that I'd never heard before! No wires running to the wall are a HUGE bonus. Pull the board out of it's case, plug in my amp, play. Couldn't be simpler. I love the charge indicator lights.

Great pedal;…but

This is a great option for shows that have no power available, or for just avoiding having to plug it into power. However, the specs say (as did the Sweetwater tech on my call before purchasing), that "Flexible charging options let you charge anywhere at any time." But when you open the package, there is a warning that says: "The 529i is intended to be used on battery power and recharged between uses. It is not recommended to connect it to wall power while powering your pedals. Doing so may cause the 529i to automatically turn off for safety reasons. Repeatedly recharging while in use may cause permanent damage and will void the warranty."

This is usually not going to be a problem in my situation, but for those days when you might have a need for many hours of use, the idea that you can't plug it in to charge while using was a bit unexepected.

529i use and advise.

When I first got the 529i, people were arguing about if you could charge it and use it at the same time. Talked to Mission engineering about this. Bottom line, you might(or might not) get away with doing both at the same time but doing so will most definitely severely shorten the 529i's battery life. You can count on those reviewers who complained the unit only lasted for months likely charged and used it at the same time. My solution? Bought as a second 529i and mounted it, like the first unit, on the underside of my pedalboard. When one runs out, I switch my pedals to 529i 2 and all is well. Works beautifully with my Sennheiser wireless setup.

No more noise

My home is not properly grounded so other power supply's were not cutting it till I was recommended the 529i. Since this is battery powered I get no noise from grounding issues anymore and it is extremely quiet. The battery life on this for my board which is constantly using 3-4 different pedals last a very long time, about 8-10 hours of use. I'm sure if you have more pedals that use more power that will go down but for my small pedal board of 5 pedals this thing is amazing.

Just what you think you need....

This is totally perfect, and I had no idea these existed until I saw a video showing it power up some high end petals with ease. I am running a Tonex pedal, EHX Epitome pedal, and various EHX specialty pedals and pitch shifters. This thing rules.
