This power supply does exactly what it’s supposed to do. It provides a stable 12V AC output and has been working reliably with my equipment without any noise, heat issues, or voltage instability.
The connector fits securely, and the unit feels solid and well-built. No hum, no interference, and no surprises—which is exactly what you want from a power supply.
It’s refreshing to find a straightforward, dependable AC-AC adapter without unnecessary complexity. I would buy it again if I needed another.
Glad to find this adaptor exists. Does exactly what I needed.
This 100 ft. DC power extension cable is just what I needed. Nice quality.
Product works great and delivered as promised.
Arrived in good condition and is exactly what I needed.
Just as pictured and described!

Works as advertised
Packed and shipped well.
Good price for a quality unit.
I don't need these my adapters want the problem need to get a return label asap
The ac-ac adaptor has brought a special vintage christmas tree back to life. Thank you
I'm using this unit to power an old 12v car stereo EQ in my home stereo. works great...clean power. I recommend.
The device appears to be solid and well built. It's the only unit I've found that has both a Variac AND an Isolation transformer in one unit. It's roughly half the price of buying both units separately (not to mention the reclaimed workspace). As near as I can tell, the output is indeed isolated from the input, as claimed, including the ground. I'm just a hobbyist, not an electrical engineer, so please accept my opinion in that that context.
I had to get Chat GPT involved before I found this adapter, and it worked. I'm happy :-).

Old Guy Hifi sent me after I researched about linear power supplies on YouTube. I have it powering my Dac. I reccomend highly 👍
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!
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.
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.
