Joyo JP05 Rechargeable Isolated Power Supply Brick with USB Port

 The JOYO JP 05 Power Supply features, 8 DC centre negative outputs, 4 x 100ma 9v, 3 x 500ma 9v and 1 switchable to 9v, 12v or 18v at 100ma. The power supply also features a 5v USB, perfect for powering USB devices & charging your phone.

To top off the feature list, it has a built-in 7.4v/4400 mAh rechargeable lithium battery pack which charges fully in 3-4 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. The power supply has a 4 stage battery indicator. You can use the supply when it is in charging mode powered by the supplied JOYO 9v 2000ma adaptor. The level of battery power will be indicated by the LED display on the top of the pedal (0% - Red flashing (charge it up!), 0-30% - Red, 30-60% - Yellow, 60-100% - Green) flashing above to show status. 8 LEDS can light up your board in a bright cool blue glow. An option to turn the LED lights on and off is readily available.. If you are using the supply as a portable unit, it would make sense to turn them off. 

This 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.

Just took delivery of my third JP05 (yes, all three are in active use on various pedalboards). Good quality power brick at a reasonable price, and delivered very fast.

Small footprint

I was sceptical buying another cheap pedal powersupply after my last cheapo "moen" crapped out after 2.5years, but you could buy 4 of these vs one of the expensive ones, and I'm not a touring musician so I rolled the dice with this one. It's very small, I like that you can turn the LEDs off too, they're blindingly bright (especially if you look at the thing to double check the 9/12/18volt switch on the last output!). I've had this for a few days, and spent maybe 4hrs so far using it, but there's no hum, running all 8 outputs together so I guess it is "isolated" (it's so small I was sceptical they were properly isolated outputs). If it lasts longer than the 3 year warranty I'll be very happy with it!

Great unit!

Just taken delivery of my second JP05 (yes, I have a LOT of pedals on a very big board!). I typically run with mains power connected, so the rechargeable battery thing is not of major importance to me, but I've certainly used it in battery mode at times also. ..... My first JP05 has been running flawlessly for over two years now so, when I needed more juice, it was a no-brainer to get another one. And yes, I could have daisy-chained the extra pedals together, particularly as the JP05 has three 500mA outlets(!), but I prefer to keep my pedals isolated from each other as much as possible, so splitting them up lets me sleep well at night ..... And those 500mA outputs are invaluable to me, becauser four of my pedals (Joyo PXL8, Nux NBP5, Boss EQ-200, Zoom MS60B) chew more than the standard 100mA built in to many power supplies ..... Am just charging my second JP05 up as I write, but my experience with the first one is that it is noiseless and reliable, and that's all I demand of a power supply ..... Incidentally, I'd rate the JP05 as a better buy than the similar but more-expensive JP04, which is bulkier, and has only 2 x 250mA rather than the 3 x 500mA. Perhaps there are reasons why the JP04 is more expensive(?) but, as far as I'm concerned, it couldn't outperform the JP05 for my purposes ..... Oh, if I had one tiny criticism (and I haven't marked it down for this), I'd just observe that the positioning and design of the on/off switch is such that it's relatively easy to accidentally have it switched on during transit, particularly if (like me) you have the power supply positioned along the side of your pedalboard, where it can come into contact with the pedalboard itself. For that reason, I'd much prefer a sliding on/off rather than an easily-bumped rocker switch. ..... And finally (unrelated to the product itself), I'd just comment that AG's delivery of this unit was nothing short of stellar — I live in provincial Queensland and, what with Covid19 delays, I expected to wait up to a week — as it turned out, I had it in my hands in less than 24 hours!!! Yet again, Artist Guitars blows the competition away in terms of product quality, value, and service.

The Joyo JP05 is a great power supply and exactly what I was looking for. It had had enough charge straight out of the box to power some pedals. I am manly using this for quiet practice where I am powering a looper pedal and a trio ( headphone out). The JP05 means that I can set up anywhere and not be tied to a power supply.

Does the job well and great value

I bought three of these after being really happy with the first one. The unit is very quiet, quieter than more expensive brands. The built-in battery is really handy and the unit is well built. Incredible value.

Seems fine so far. Liking the cordless chargability thing. It's a pretty hefty brick. Accommodates an 18V or 12V pedal which is cool. Quality seems not too bad.

Excellent power supply very quick re charge time and quality build

Got one of these last month, and so far have used it for 2x 3hr jam sessions without having to recharge it (to be honest I forgot to plug it in before last night's rehearsal). Noiseless. and it slots underneath my pedalboard nicely. A great unit at an excellent price!

Great product

Let me start by saying I have a power supply worth over $ 200, but this is my go to supply. I love that it charges up and doesn't need to be connected to a power point all the time. It stays charged for hours. This year I've started doing live gigs. For my most recent gig I used it to power 2 EHX pedals (that come with their own power supply), a TC Electronics Pedal and 1 Boss Pedal. It handled it all. no sweat, simply running off the charged Supply Brick. I only needed power for my amp. It's definitely isolated, no noise problem. This is a good solid build and all the cables are good quality. It also has light indicators to show when it's on and the level of charge. A steal at the price. One of the best purchases I've made in recent years. I can't recommend this highly enough, it's great value and a great performer.
