## Description

Product Description JP05 Built-in 4400mAh Rechargable Battery Pedal Power Supply JOYO's JP-05 power supply has 8 DC outputs and 1 standard USB output, one of the 8 outputs can be switched between 9V, 12V and 18V for the odd pedals in your collection that just want a little bit more voltage. The 5V USB output enables you to load your cell phone, iPad and other portable devices. JOYO Pedal Power Supply for Guitar Pedal (JP-05), Directly provided by manufacturer JOYO Technology, it's over decade of brand reputation. To top off the feature list, the power supply has a built in 7.4V/4400 mAh rechargeable battery pack which charges fully in 2.5 hours making sure that you are never without power. Each output of the power supply features independent filters, output overload & short-circuit protection protecting your pedals and filtering out any unwanted noises. - DC Outputs 1-3 are 9V centre negative with 500mA each, suitable for many high end digital pedals requiring more oomph and suitable for many standard pedals too requiring less. In theory you could even run a daisy for 5 100mA pedals of each output, that's 15 pedals! If you are thinking of doing that, read our guide on power supplies for best practices. - DC Outputs 4-7 are also 9V centre negative with 100ma, suitable for the most guitar pedals at 100mA or less. - DC Output 8 can be switched from 9v,12v or 18v at 100ma. So that makes a pretty versatile power supply, useful for guitar effects and other electronic instruments. The JOYO JP-05 is even supplied with a polarity converter for instruments/effects that require a centre positive supply. Details LED Power Indicator Each output socket has a related LED power indicator. The LED power indicator goes out if any output overloads or short-circuit protected.

Review: Great value for a lot of power. - 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.

## Questions & Answers

**Q: When using the built in battery, is there any noise? Some people are saying that this unit isn't isolated**
A: No noise.  Just like a big 9 volt battery.  The noise comes from the transformer,  the power supply.  Even plugged in, it is pretty quiet.  Love it!

**Q: are all the  outputs are isolated? No they are not**
A: I have read definitions in terms of multi-output devices, that the grounds must be isolated, and this is not the case here. 0 ohms from center pin to center pin on adjacent connectors is enough to disqualify. However, as long as there are no ground loops in your rig, and clean connectors and cables, this shouldn't be a problem, and has never been a problem to me. This supply has inside a lot of engineering design. I opened it up and spotted a STM8S003 micro-controller and an FP5139 Boost convert chip. I wish I could get a look at the schematics to see what's really going on in there. 

But I've been using mine for about a year now, and it has been great. It powers my Electro-Harmonix 5MM power amp with 3 or 4 pedals running for hours on a charge. Never any hum or apparent interaction between pedals.

**Q: When the internal battery is dead, can it be plugged in the wall to use still?**
A: It is a rechargeable battery. The performance of a dead battery being used while being charged (It is charging if it is plugged in) will be greatly diminished. If you can plug it in there is no need for a battery powered unit. Try this instead. https://www.amazon.com/dp/B07D8NZKS6/ref=sspa_dk_hqp_detail_aax_0?psc=1&spLa=ZW5jcnlwdGVkUXVhbGlmaWVyPUEzVFNLSFdSR0JEV0FRJmVuY3J5cHRlZElkPUEwOTcyMDM4SzlIQUpZSlFaUFYxJmVuY3J5cHRlZEFkSWQ9QTA0MTYyODIzRjNXOU44WERQWkRFJndpZGdldE5hbWU9c3BfaHFwX3NoYXJlZCZhY3Rpb249Y2xpY2tSZWRpcmVjdCZkb05vdExvZ0NsaWNrPXRydWU=

**Q: How long are the are the 8 power cables ?**
A: These cables are about 22 inches. (55cm) I hope this helps.

### ⭐⭐⭐⭐⭐ Joyo PSU Rocks the house.
*by M***E on 19 July 2025*

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.
