It’ll work.

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.

12V AC @ 1000mA Power Supply 2.1 x 5.5mm

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!

Exceeds Expectations -- Excellent Product!

I’m highly impressed with the versatility and user-friendly design of the AC/DC Power Shack Universal Power Adapter. It arrived securely packaged and was remarkably intuitive to use right out of the box. With seven adjustable voltage settings (1.5V to 12V DC) and six interchangeable plugs, this adapter accommodates a wide range of devices and configurations. The build quality feels robust and reliable. For its performance and flexibility, this adapter is well worth the investment.
