Best Keyboard Power Supplies in 2020

NEUMA Guitar Effects Pedal Power Supply Adapter 9V DC 1A (1000mA) with Cable 5 Way Daisy Chain Cord Review:

I ordered the Neuma Pedal Power Supply because I am building a simple pedalboard to take with me to local Open Mic Nights, without having to take my gigging pedal board along, and needed a power supply. The box is simple but durable enough to protect the item while in transit. The cable seems very durable and, from end to end, is about 6 feet long. It was able to power 5 pedals with plenty of room to adjust the spacing of the pedals. Some of the wall-wart power adapters are known for producing excess unwanted noise in the signal chain. The Neuma power supply produced no unwanted noise. It was very quiet, which is always a good thing. The plugs fit snugly but comfortably into the pedals and didn't seem to be easily shaken loose. This is great for musicians who tend to turn their pedals on and off regularly during their performance. The pedal board I am building is going to consist of several micro pedals and this is the perfect solution to my power supply needs.

Power Adapter for Casio Keyboard AD-5 9V: USA UL Listed 2Y Warranty EXTRA LONG Cord AD-5 AD-5MU AD-5MR WK-110 WK-200 LK-43 LK-100 LK-220 CTK-496 CTK-573 CTK-700 CTK-710 CTK-720 CTK-2100 Review:

It can be hard to find the exact adapter for old equipment, but this one worked perfectly for my 1987 casio keyboard. Pay attention to both the inner and outer diameter of the plug and the polarity of the pin to make sure you have the right one. I appreciate this company having the adaptor nameAD-5 9V and the specs so that I could zero in on the right adaptor. Besides it being the right power output and plug size, I appreciate the blue light on the adaptor to indicate that power is going through it.

9.5V AC/DC Adapter for Casio ADE95100LU - UL Listed Power Supply Charger for Casio Piano Keyboard - Only Compatible for Listed Models (8.4 Ft Long Cord) Review:

Yesterday I gave this 1 star and said it didn't work. Today I decided to try one more time and while the keyboard (SA76) was plugged in with the adapter, I happened to pick the keyboard up and was holding it at an odd angle when suddenly the sound came booming out! I discovered by moving the keyboard around that there is a loose connection in the keyboard itself. So I am revising my review! I also want to mention that the seller FouceClaus left a comment on my negative review, offering to refund. ( I had missed Amazon's return deadline since I hadn't tried out the adapter soon enough -- I just assumed it would work because so many customers were happy with it. I am glad I discovered the real situation and since I doubt my keyboard (which is kind of old) can be repaired, I am going to get a new one.

12V Power Adapter, Replacement for Yamaha PA130 PA150, Universal Power Supply Charger Adaptor for Yamaha Keyboard PA PSR YPG YPT DD Series by LotFancy, UL Listed, 8.2Ft Cord Review:

Sadly I lost my original cable to my keyboard and couldnt find it ( i have a Yamaha PSRF51). I was going to go back to Guitar Center and purchase a new one but I checked Amazon first. This one said universal and it was a fraction of the price (GC I got it originally for $40). I received the item and the adapter works perfectly. Genuinely happy for the price i paid.

Yamaha PA130 120 Volt Keyboard AC Power Adaptor Review:

Update May 25, 2014: Still working great-with no issues.

Original review:
We bought this adapter to go with our Yamaha PSRE343 that we purchased for our daughter a couple of months prior. The adapter works perfectly for our model keyboard that we got and we feel much more confident buying a YAMAHA branded AC adapter (considering the no-name brand was virtually the same price).

The cord is about 4 feet long and works good for our needs (it is actually plugged in very close to the outlet anyway). (Obviously) saves on batteries by using this and we have found that the sound quality (volume) is better when using this instead of the batteries.

I would highly recommend purchasing this together with the particular keyboard that you get (making sure that it is compatible of course). I think it's absolutely crazy that they aren't already included with the keyboards at time of purchase. That being said, this is cord has been great, does what it needs to and doesn't cost too much.

Power Adapter for Yamaha PA130 PA150, UL listed 12V AC/DC Replacement Power Supply Charger Plug Cord for Yamaha PA PSR YPG YPT DD Series Keyboard - Only Compatible for Listed Models (8.4 Ft Long Cord) Review:

This power adapter is nicely made and arrived promptly. Although advertised as a Yamaha product, its label says FouceClaus. This is OK with me, since I expect that Yamaha out-sources this type of product. I like that it is dual voltage AC input 100 to 240 V, so that it can be used in the USA at 120 V and also overseas at 230 V. As reported by other reviewers, I also like its 'sideways' configuration, so that it uses less length along a typical power strip. I like the long DC output chord of 8+ feet - it provides more convenience in reaching an AC power outlet - especially in a gig situation where several players also need AC power. The DC output of 12 v at 1.5 A is more than adequate for Yamaha keyboards My only negative comment is that it has no indicator light to show that it is on. It would be nice to have this, so that I know that the wall outlet/power strip that I am plugged into has AC power. It has c UL us listing. Excellent quality and workmanship!

9V AC/DC Power Adapter for Casio Piano Keyboard, Zoom Guitar Multi Effects Pedal, BOSS, Dunlop, DanElectro, DigiTech, Ditto, Electro Harmonix, TC Electronic by LotFancy, UL Listed, Center Negative Review:

The basic rundown here is that you have a slender wall plug with a sideways orientation. So, take a look at the power strip it's going into and make sure it's a logical fit. Some power strips turn the plugs sideways or another direction to help on their own. Next, you have a very long cord. I am using this on a pedal board, so I would have preferred less excess, but to be nice they include a velcro strap to bundle the cable in the way depicted in the product image. The most vital feature that drew me to this power adapter, is the L shaped plug that goes into the unit you are powering. I use this on both a Boss bass overdrive pedal, and a Biyang reverb pedal. It was beneficial in both cases to have the L shaped plug, because these pedals put their power input on the back, causing up to an inch of wasted space using a standard strait style power adapter. Both my stomp pedals have had very little exposure to power adapters, so the power port still has a snug feel. Having the L-shaped end makes me feel very secure that these fresh power ports won't soon become wobbly. Anyone who has had any kind of guitar pedal or small unit constantly having the power plugged and unplugged...they get wobbly fast, which eventually leads to the power cutting out. While the plug does insert with the right amount of snugness, I will just add that there is a bit of chrome exposed, when the plug is inserted. It does not insert flush to the plastic part of the plug. This is no big deal, but just something to note and expect when you are buying a power adapter that is not designed specifically for just one unit or brand. Lastly, I will say the grade of wire used is pretty thin. This does make it nicely flexible, but I am curious how it would hold up over time, after being exposed to a bit of heat, and a few yanks, like you would expect to encounter on tour (if you don't have a pedal board, which you should totally have). Hopefully this answers every possible question you could have, except if it works on my your gear in particular, but that is just something you will have to read and confirm. It works perfectly with Boss and Biyang pedals.

Donner Dp-1 Guitar Pedal Power Supply 10 Isolated DC Output for 9V/12V/18V Effect Pedal Review:

This power supply is an excellent value with a really nice array of power supply options. I especially like having dedicated 18v and 12v slots available in addition to the usual 9v. Including such a wide variety of power cabling is a major bonus. At this price point there is no way you're beating this option, you'd have to go up to a voodoo supply or something at a far higher price to get any additional benefits.

I've got this powering a Boss TU2, Boss NS2, Fulltone OCD (18v), Catalinbread Topanga (at 12v), Electro-Harmonix Canyon Delay, Boss TR2, Morley ABC switcher, and Cusack More Louder on my board and have been running this way for about a year with no hiccups, no problems, no noise, no headaches. The blue LED's look cool glowing under the board and included cabling have held up great/no issues with quality control in any of the components I received. 10/10 would recommend to a friend.

Donner DPA-1 Pedal Power Supply Adapter 9V DC 1A Tip Negative 5 Way Daisy Chain Cables for Effect Pedal Review:

There's not much to say; this combo just works. I have a few ongoing projects with different pedalboard setups and power supplies. Two boards run on isolated power supplies (Voodoo Lab Pedal Power 2 Plus Isolated Power Supply is my go to choice for these setups) and two of my smaller boards run on practical 9v power supplies w/ daisy chains. The Donner DPA-1 Pedal Power Supply Adapter 9V DC 1A Tip Negative 5 Way Daisy Chain Cables for Effect Pedal performs just as well as my Truetone 1 Spot Combo Pack. The cable is long and pliable to really snake through your board's patch cables to the pedals and the barrels fit well on all of my pedals.

Yes, you do miss out on converters included in some of the pricier options. However, if you're setting up a board with all the same power connections you'd be hard pressed to find a more cost effective way to power up your board.
