Works great, puts out approximately 7.4 VAC which is probably a combination of build tolerance and my actual outlet voltage being a little higher than average determining this, but worked perfect for my application. These are a little hard to find at this voltage, so was happy getting one here. Shipping was quick, well made product, would buy again.
I am very satisfied with the power supply, it works for various applications. I was most impressed by how fast I received it in the mail. I ordered one from Amazon and ended up canceling the order after 3 weeks waiting for them to ship it. You guys are awesome!
easy ordering and quick shipping. product came well packaged and sealed. it meant all my expectations that it was meant to be used for. awesome company to do business with.
Here in central Florida, the lightning capitol of the USA, we get frequent damaging power surges from lightning strikes on the power lines that has damaged electronic equipment. I inserted two isolation transformers to protect my computer and tv. So far no more surge problems.
We purchased an AC-DC Linear Power Supply 12V DC @ 500mA; 2.1 x 5.5mm NEGATIVE center polarity wall adapter from AC-DC PowerShack. The transaction exceeded our expectations in every aspect; price, shipping speed, communication and item quality. We will gladly do business with them again, buy with confidence they are deserving of your business! AAA++++
I purchased this for my fiber optic Hummingbird lamp because it has a color wheel synchrous motor in which requires the above power adapter. This company is the only company I found that carries these adapters. I bought one, and now have bought 2 more, one for my sister who has the same lamp and another for me, because I recently purchased another fiber optic lamp. Hans was very helpful and I truly appreciate the help he provided. Thank you Hans!

Works for non-standard audio effects
Most guitar pedals and effects boxes are standard 9V center negative DC, but my Alesis Phlngr actually needs 9V AC. I had to find the right plug size which ended up being 2.5 mm inner diameter instead of 2.1mm like this adapter. This site also sells the converter from 2.1x5.5 mm to 2.5x5.5 mm that allows me to interface with this unit. Works as intended.

Replacement for BOSS SE-50 Supply
I bought this adapter for my Boss SE-50 since I did not want to spend $40+ on a giant brick known as the BRB-120. I had one of the original Roland power supplies back in the day and hated how much space it took up just for a half-1U rackmount. However the plug on the AC/AC adapter I bought here is 2.1mm x 5.5mm so I also got a converter on this website to adapt it to the 3.0mm x 6.3mm plug in the back of the SE-50. I have confirmed this to be operational, and a less expensive shoehorn for the BRB-120.

Cord is fine, not the best quality but it works for what I needed it to do. Unfortunately despite it being a $5 part I paid $15 total so I would get it quicker and it arrived 3 days after it said it would. Kind of shady to have someone pay for express and then it take as long as a normal delivery would’ve taken.
Thank you for your positive feedback! We're glad to hear that the DC Barrel Plug Adapter is working perfectly for you. Let us know if you have any further questions or concerns. Happy to assist!
Tried using to operate a 6v siren which pulls 2amps on startup and then drops significantly. Unit is unable to handle 2 amp startup although it is advertised as 4 amp.
Hi there,
I'm sorry to hear that our Adjustable DC Regulated Switching Power Supply did not work for your 6v siren. Our unit is rated at a maximum of 4 amps, so it should have been able to handle the 2 amp startup. We would like to reach out to you and see if there is a way we can remedy this situation. Please allow us the opportunity to assist you. Thank you for bringing this to our attention.

Hi there! Thank you for your positive review of our AC-AC Power Supply. We're glad to hear that it's working well for you and that you were able to find a product with the specific voltage you needed. At 120VAC input, it's normal for the power supply to read about 1.5VAC higher on an open circuit. But once it's plugged into your device, it should lower down to the advertised voltage. Thank you for choosing our product and we hope to see you again!
