I built a second guitar pedal board and needed more stable power without using several 9 volt supplies. My normal go to is one-spot and have never had any issues. While perusing Amazon, I decided to try the Donner version. It works really well! I bought another one because I needed 9 volts for an electronic keyboard. It also works like a champ. No noise is added to the chain; no inconsistent power fluctuations. Both deliveries arrived in a super-timely fashion. You get 5 stars and 5 thumbs for an excellent product. Best, EJ

I've been using a Visual Sound One-Spot on my pedalboard for probably 10 years, and I love it. I put together a small pedalboard with a compressor, EQ, chorus, reverb and looper for some acoustic gigs and decided to give this unit a try. After a few weeks of use, so far, so good. Quality seems to be fine, provides quiet power, good length of chord to the wall wart - no issues to speak of.

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.

These work great for the odd use I use them for - powering LEGO Power Functions (PF) motors. LEGO only sells battery boxes for their PF system; they operate on 9V, and so this power supply works great to power multiple PF motors without the hassle of batteries. I don't know what else to say about something like this - they either work or they don't; this works as described.

Really good adapter. So far I have two of them. I use one with the daisy chain to power on three pedals (a tube screamer, a kokko compressor and a donner killer booster), and the other one only to power on a little looper pedal. I was using only one adapter for all the pedals before (including one preamp), but I got a hum specially when the looper was on. After trying some configurations I realized that at least the looper needed its own isolated power supply, so I bought a second one, and the hum is gone. So in my opinion, so far the power supply is really great and quiet, but if you connect lots of pedals with the daisy chain you're probably getting the not desired ground loop, no matter the brand of the power supply adapter. And in my experience if you have a looper pedal, you need a dedicated adapter for it.

Update: I received the new item I ordered with the refunded money. This item came properly packaged and complete. Tested it and it works as advertised. So am updating to 5 stars. Original review: Item not as listed. Did not include the Daisy chained tips. Maybe I got a bad unit. Amazon refunded. Packaging did not seem to be ok. Seemed like it had been open. Under green tape you can see mentions of more than one pedal.

This consists of a a simple and straightfoward 9V 1A negative tip power supply, plus a 5 plug daisy chain cable. You plug the charger into the daisy chain cable and then plug the daisy chain plugs into your effect pedals.The distance between the plugs on the daisy chain are about 12 inches, so you'll have enough flexibility to move your stuff around.The plugs go into the sockets on the pedals with a satisfying click and all of it doesn't seem to be overly thin or weak. The power supply is quiet - I haven't noticed any hum (or any noise) in my effect chain - looper, wah, TS9, HM2 and equalizer. The power supply seems to have enough juice to power the pedals (it should - they're designed to run on milliAmps off of 9v batteries). Build quality is decent - it looks and feels like any other wall wart style plug, not particularly large, about the size of two matchboxes stacked on each other. I wouldn't drive a car over it, but it seems light and small enough not to suffer damage if it fell on concrete from a few feet up (not experimentally verified). I'm happy with the purchase, it was exactly what I wanted.

Very good product totally as described. I read some bad reviews here about noise or hum with this product, but in my case is totally quiet and I recommend it. I need to say that I am using very good quality cables and the guitar is totally shielded from the inside with conductive paint and aluminium, so no hum or noise before or after using this product. I am connecting five BOSS pedals, one Wah from VOX and a Fender Starcaster flanger with no problems as you can see in the pictures.

Works perfect. A must have if you run multiple pedals on a pedal board.

Was skeptical due to reviews that talked about hisses or hum noise and that it was replacing a power supply that has 1700 ma power source with only 1000 ma. However, it is currently lowering 5 pedals, Boss looper, Ibanez delay and Behringer tube overdrive, fender tuner, Boss drum computer control. I also use a boss distortion pedal but don't have it in the board right now. No noise whatsoever, everything powered fine. The cord is thicker than my old power supply. The cord on it has split right at where it connects to the supply leaving exposed wires and a potential short out. I think this one will stand up better to the repetitive packing and unpacking for gigs.
