Reliable, old-school power for sensitive electronics. The 584D is a classic linear, non-regulated universal adapter. Unlike modern switching supplies, linear adapters are preferred by hobbyists and audiophiles for their simplicity and low electromagnetic interference (EMI) when powering vintage radios, small hobby projects, and low-drain devices.

Out of Stock Notice: This model is being discontinued. For higher power requirements once this item is sold out, we recommend the PHC-600K (600mA).

Technical Specifications:

Input: 120VAC 60Hz 7W (Standard US Outlet)
Selectable DC Output: 1.5V, 3V, 4.5V, 6V, 7.5V, 9V, and 12V
Current: 300mA Max (0.3 Amp)
Type: Linear Non-Regulated (UL and CSA Approved)
Polarity: REVERSIBLE. Features a manual polarity switch for Center-Positive or Center-Negative devices.

What’s in the Box:

584D Multi-Voltage Power Adapter
6 Interchangeable Tip Sizes: 3.5mm mono, 1.3x3.5mm, 1.7x4.0mm, 2.1x5.5mm, 2.5x5.5mm, and 2.35x0.75mm.

Safety First: This is a NON-REGULATED supply. The output voltage may be slightly higher than the setting if the device connected draws very little current.

⚠️ IMPORTANT: Always verify your device’s required voltage and polarity before use. Setting the incorrect polarity can damage your equipment.

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.

Thank you so much for taking the time to leave such a positive review for our DC Universal Power Adapter. We take pride in providing a high-quality product and we are happy to hear that it met your needs. Thank you for choosing our product and for your support!

so far so good

As long as it keeps working everything is fine.
Thanks, Rob

Seems Decent

Lots of settings and attachments. Should be useful. Bought to replace a plug for a radio. The power supply is some new switching stuff that totally blocks AM. Since no batteries makes no sense! Supposedly a Biden mandate (no surprise).

Thank you for taking the time to leave a review. We're glad to hear that our DC Universal Power Adapter with multiple voltage options and attachments is proving to be useful for your needs. We apologize for any inconvenience caused by the new switching technology that may be blocking AM on your radio. We will definitely take your feedback into consideration for future improvements.

1.5V DC never works

Sadly the 1.5V DC always gives me 3.5V output. 12VDC always gives around 20V output.

Hello Ning Yu,
Sorry the power supply wasn't what you were expecting. Please understand this is a AC-DC 'non-regulated' power supply. Therefore, a no load reading on a non-regulated supply typically is 1.5x higher. The voltage would drop to the intended setting once there is a load on it.

You would need a 'regulated' or a switching power supply which are always regulated. Our PHC-1000k and PHC-2200W models are regulated and would read about 0.2VDC higher on a no load meter reading. Hope that helps.

Regards,
Hans

product received in good condition, and works real well. thanks

Hard-to-Find Item for 6.5V Digital Camera

After much searching elsewhere, I was happy to find
this item on your website.
My older digital camera requires 6.5V DC input when
using an AC adapter, and most new multi-voltage adapters
no longer include a 6.5V setting. This one does.
The adapter is well made and includes multiple tip sizes,
as well as a special tool for selecting the output voltage.
The output voltage selector switch is very well designed,
and has nice positive stops at each voltage position.
I also have a newer 5V DC input camera, so it's great to
have an adapter that is so easily switchable.
Shipping was very prompt, and the adapter arrived in
perfect shape.
