The 12 volt ac supply outputs slightly less than 14 volts so under load this works for my application.

This power supply replaces one for a 32 inch fiber optic Christmas tree that belonged to my mother. When I unpacked the box this year, the old power supply fell out and broke. The new one is a perfect replacement, and I was pleased by the quick delivery. Thanks very much!
Appreciate the review Louie. So happy the correct power supply and plug size was a perfect match for your lights.
Arrived on time, I wish it worked because it cost me more to have it shipped then the cost for the Power Supply. Not a happy customer

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!
Thank you for your kind words Marcia. I hope the 2 additional power supply with the modified plug works well with your wonderful lamps.

Needed it for my cb radio
Quick ship. Cable works fine
Needed for bench work on some older type tube receivers. Fit my needs also the two outlets provided a plus. Received quickly and well packed. Completive pricing
and reasonable shipping would use again.
It worked fine! Had no issues with it.
Variable Transformer 5 Amp (500 Watts); 0~130VAC Output
Good price for the item value.
Could not be more pleased with the product and service provided. Took a while to find a product that combined a variable transformer with a true MAINS, ground isolation. Unlike most cheaper competitors offerings, the digital readout and dial for this transformer is fairly accurate when checked with a DMM. Great product for a hobbyist tech.
Perfectly fit the bill for what I needed
We were searching everywhere for the correct power outlet and they were the only ones that helped us!! Huge effort for an inexpensive product
I’m very pleased with my purchase good quality very nice. I would highly recommend it. Thank you.
I can’t imagine somebody could mess up a power adapter and in this case, they came through as expected. They worked perfectly and it seems durable.
Exact replacement for my blown fuse back up and running. Fast shipping.
They had exactly what I needed to keep my star wars ornament working
Thanks guys
Works well. Beautiful construction.Great job on the business end also! Bob Gatts
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!

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.
