Joyo JP05 Rechargeable 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.

Long lasting rechargeable noise free power supply

By: on 4 October 2021
I was a bit hesitant to give this rechargeable power supply a try, but for the price it was worth a shot. It worked out better than I expected, firstly it comes with plenty of power leads for pedals, 90degree one end, straight the other, you can plug it in to the wall to keep charged but I'm able to run all 7 pedals on my board the whole night unplugged, all the noises I was getting from plug packs are gone and I just recharge after I get home. Compact enough to velcro under the front of my board and use the ( switchable ) blue LEDs as a backlight for the board, love it !

Thank you so much for sharing your experience with the JP05 power supply. This really helps us and other customers who are looking for noise problems with their pedals.

Average at best

Takes longer to charge than the use you will get out of it, even keeping the display lights off.Creates a fair bit of the whining noise with 2 of my pedals. Kind of figured it would be too good to be true.

First of all, the guys from Artist deserve five stars. Their service is awesome and customer care second to none. Now for the product... Isolation must not be very good, as it introduces a whiny noise as soon as you connect more than one pedal to it. If I use separate power supplies, the noise disappears. I have tried it with a Strymon Timeline and a Strymon Lex together, both within the max current draw so that's not the problem. Also tried with the Timeline and a compressor drawing 100mA and the whine is still there. I then unplugged and just used it as a battery pack... and the whine persists if more than one pedal is connected to it. I guess if you want a truly isolated power supply that won't introduce noise to your signal either spend a lot more money, or use loads of wall warts?

Excellent product (Joyo JP05) & 1st rate service f

So far the Joyo JP05 has delivered exactly what it promises .. 9v power to an array of up to 10 guitar pedals, all isolated from mains line-level hum whilst running from it's own 'go-anywhere' inbuilt battery (note: it is not actually isolated whilst connected to the mains though). Very pleased so far, if it continues to function well I would get another down the track .. it is a very handy piece of kit. The service from Artist Guitars has been exemplary .. very fast & efficient .. highly recommended.

Seemed OK at first. Then soon changed. Lasts for about 5 minutes and won't even work when it's plugged in
