JOYO Built-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.

This has been a great power unit. Fits neatly under my board and powers 8 pedals. Has survived being kicked around at 30 or so rowdy gigs. No noise or other issues.

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.

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.

Absolutely fantastic power supply for the money! I'm surprised it's so cheap! Powers a good chunk of my pedals and has a good variety of outputs for different miliamps and voltages to power those power hungry digital pedals. I've had Absolutely no problem with any excess noise from the power supply and I'm also completely blown away by how long the battery lasts! Even when it was on the red indication, which means you need to charge it, I got another 2 and a half hours out of it powering 8 pedals! Literally can't fault it! Absolute steal at this price point!

The concept us good and the item seems well-built. It certainly avoids relying on finding a power socket on a gig. Just don't rely on the specs. I have never got a full recharge in less than 3.5 hours, usually nearer 4. To be really useful it has to be fitted inside the pedal board. That means extending the contacts and putting in switch and sockets. If you're uneasy about doing that it may not be ideal for you.

Have a looper and three pedals which had a lot of hum with simple power supply and daisy chain. This has reduced the hum to next to nothing and even improved the sound of my guitars. Well built and good price.

Great PSU, works well, low noise, great price. I'm using it to power 3 high power 500mA units and a couple of standard pedal. I've had noise issues in the past with individual PSUs but this does a great job powering everything, adding no noise, all from a single plug. great unit.
