I've been considering getting a variable output isolation transformer for quite a few years, but I always assumed that they were expensive. When I purchased a Japanese market synthesizer (100 volts AC power requirements), I needed a step-down transformer. During my search, I came across this little gem at a very surprisingly reasonable price. The reviews were good, so I bought it.
It was shipped right away, and arrived within 2 days. It's a wonderful unit, and it works perfectly!
I would highly recommend that AC-DC PowerShack be checked out if you're looking for this or any other product they carry. You won't be disappointed!
I used this adapter in combination with a USB C to 2.1mm x 5.5mm to create a USB C 12v adapter for my equipment. Works great! Now I don't have to be tethered to an extension cord while I work.
Fit is perfect, quality is decent. Couldn't ask for more.
Quick and easy buy. Shipping was fast would recommend buying from them.
Good value!
All good works great thank you
Good quality. Very happy with my purchase
Exactly as ordered. Powered Christmas display of moving ice skaters. Fun for everyone!
It did a good job as advertised. I was getting a hum when I turned on my subwoofer. I plugged the sub directly to the isolation transformer. It decreased it by about 90%. Maybe if I plug my sub into my power conditioner and then plug the power conditioner into the transformer it might eliminate the hum completely. I have not tried it yet. Have not had time,but the hum is barely noticeable now. I have to get very close to the sub to detect it. Very happy even with the 90% hum reduction
I'll will definitately keep it
Great product..
It's hard to beat the price for a variable isolation transformer. Works well.
Used these to power my legacy Hallmark Star Trek ornaments and they work great. AC/AC is hard to find and the Powershack had these quality units and shipped them quick. Wish I’d had another option besides USPS for shipping but otherwise great product and experience.
Product came on time exactly as described. Worked perfectly.

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.

There are no guarantees that a transformer will cure any noise issue, and this did not. Also, because it hums, it is introducing noise into the room. I did not expect this. I am debating on whether to return it, redeploy to another area, or to upgrade to a balanced power solution, etc. It has serious heft, so I am sure its a good isolation transformer. I feel like it may have opened up/uncompressed the low end quite a bit, but can not measure this accurately.
Thank you for sharing your experience with our 1000VA Isolation Transformer. We apologize that it did not fully resolve your noise issue. While we cannot guarantee that our transformer will solve all noise problems, we do stand by its quality and effectiveness as an isolation transformer.
Regarding the hum, I will reach out to you to see if we can remedy the problem or provide a solution to your satisfaction.
We appreciate your feedback and are always looking for ways to improve our products.
