JOYOBuilt-in 4400mAh Rechargeable Battery Guitar Effect Pedal Power Supply 8 Outputs 9V 12V 18V (100mA, 500mA) Jacks & 5V/1A USB Port (JP-05)

Excellent device. Good value for money. Plenty of outputs for many pedals and three of them are 500mA outputs which is great for power-hungry pedals. Easy to charge and also has a light switch to turn off the bright led lights if required. Nice compact design which is built very well. I purchased to power pedals that are prone to ground noise in a small studio and it is now completely noiseless. Highly recommended.

A power supply I bought in order to rig up some pedals I had in a toolbox inside the lid of a Boss BCB-6 which was gathering dust in my wardrobe.I already had a Joyo pedal so I figured this PSU was likely to work with it. I was right.I had initially bought a cheap PSU with a plug and daisy chain elsewhere but immediately recognised it was noisy and it was not up to the task.I clearly needed something substantial, and thus needed to spend a bit more.A few of similar unbranded units get poor reviews.I was pleased to discover this Joyo unit does not hum or make unnecessary noise. It had no problem powering up each of my pedals. It was easy to set up and I ended up using Velcro to fix it inside the lid and stop it slipping about.There are a number of choices for voltage, 9V, 12V and 18V. My pedals were all 9V. There are blue LEDs that light up to show you the unit is switched on and powered up, and probably provide a bit of extra light if you are on stage. You can also turn this feature off if it's not for you.In short, this does work and it works well. It currently powers six pedals and the maximum is ten.Installation was simple, and although it cost a lot more than the £8 cheap plug-in daisy chain I initially bought it's miles better. I think it was about £30. It was worth the extra, no question.It's only had light home use so I can't vouch for its longevity or extended use under stage conditions, but I have had no significant problems with it and find it easy to recommend this Joyo PSU to a casual guitarist who just wants to pick up and play with the minimum of fuss.One point worth mentioning. There were a couple of small extension leads in the box. I found them to be hopeless. They don't work. The output jacks didn't go all the way in to power up some of my pedals. Avoid using them altogether if you can.Also, read the instructions to make sure you use the right leads in the right places, as otherwise they could cause some damage as well as inconvenience. Check the ratings of your pedals, so you plug them into the right slots.Overall, a pretty simple upgrade and I'm glad I got it. Recommended.

I bought this to power pedals on my guitto board. Fits perfectly and as it’s a battery too makes like easier not needing to plug in. Good value, all the cables are of sufficient quality, battery has a long charge running analogue pedals. Can even charge your mobile phone.

Very good product. Really very good stable and affordable price

does what its meant to

Unit seems solid and well built and I barely get any noise with all 10 slots plugged in. I honestly wonder how much more I would have to spend to get a power supply that made a reasonable improvement to sound. If you're looking for solid power supply that doesn't break that bank you couldn't do much better than this.

A fantastic power supply with enough power to last a whole show and then some. Small and neat so you can tuck it away on your pedalboard and all the power cables are supplied.9v and 12v pedals are catered for, plenty of volts for all the digital stuff and it's nice to be able to charge your phone or iPad while you're playing. So good I bought two of them.

Ignore expensive isolated PSUs for smaller pedal boards and get this. 8 outlets and a full charge will last about 7 hours. No noise/interference at all using a combination of analogue and digital pedals.
