The high-capacity solution for power-hungry electronics. The PHC-2200W is a heavy-duty switching regulated universal AC-DC adapter delivering a robust 2500mA (2.5A) output. It is the professional choice for modern electronics, high-end audio equipment, and networking hardware that demand more current than standard adapters can provide.

With 6 interchangeable tips, the PHC-2200W offers broad compatibility to ensure a secure fit for a wide range of devices — including high-drain legacy electronics.

Technical Specifications

Input: 90–240VAC, 50/60Hz, 0.6A (Global Voltage Compatibility)
Selectable DC Output: 3V, 5V, 6V, 7.5V, 9V, and 12V DC (Precision regulated)
Current Capacity: 2500mA Max (2.5A) — backward compatible with devices requiring less amperage (e.g., 500mA, 1A, 1.5A, 2A)
Cord Length: 6ft (Extra long for easy setup)
Safety Features: Switching regulated for constant voltage output and integrated short-circuit protection
Polarity: REVERSIBLE (Detachable tips allow both Center-Positive and Center-Negative configurations)

Legacy high-drain electronics and professional lab equipment

Frequently Asked Questions (FAQ)

Q: Can I use this adapter with a device that requires less than 2500mA (e.g., 300mA, 500mA, 1A, or 2A)?
A: Yes. The 2500mA rating is the maximum capacity. Your device will only draw the amperage it requires, making this adapter fully safe for devices needing 2500mA or less.

Q: How do I select the correct polarity for my device?
A: Check your device or original power supply for a polarity symbol (+ ---C--- -). To change polarity on the PHC-2200W, simply align the tip's polarity indicator (+ or -) with the arrow on the cable connector prior to plugging it in.

Q: Is this power supply regulated?
A: Yes. Unlike older unregulated transformer supplies that spike in voltage when unloaded, this switching regulated adapter maintains a constant, safe voltage output regardless of the load.

⚠️ IMPORTANT: Always verify your device’s required voltage, tip dimension, and polarity (+/-) prior to connecting. Applying incorrect voltage or polarity can cause damage to your device or adapter. If you need assistance verifying compatibility, please contact our support team.

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

Hi Rob, thanks for leaving a review! We're glad to hear that the DC Universal Power Adapter is working well for you. If you ever need any assistance, please don't hesitate to reach out to us. Happy powering!

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. If you have any further concerns or questions, please don't hesitate to reach out to us. We appreciate your support!

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.
