Yealink 12V 1A Power Supply PS12V1000US
Frequently Asked Questions
First, confirm the wall outlet is live by plugging in a lamp or another small device. Then check that the barrel connector is fully seated in the phone’s power port—sometimes it feels snug but isn’t making full contact. If possible, try the adapter with another compatible Yealink model to see if the problem follows the adapter or stays with the phone.
A small amount of warmth is normal while it is under load, but it should never be hot to the touch. Make sure the adapter is in a well-ventilated area and not buried under papers or inside a cable tray. If it becomes hot enough to be uncomfortable, unplug it immediately and try a different outlet to rule out a wiring issue before using it again.
Intermittent power often points to a loose connection or a damaged cable. Inspect the entire length of the cord for kinks or cuts, and try gently wiggling the connector at the phone end while watching the screen. If the phone stabilizes when you hold the connector a certain way, the adapter may need to be replaced.
It is only guaranteed to work safely with the CP925, CP935W, VP59, and MP58 WH E2. While the barrel size and voltage might match other models, the amperage and pin polarity could differ, which can cause erratic behavior or permanent damage. Stick to the listed devices.
No, the phone will automatically draw power from the adapter and ignore PoE when both are connected. There is no configuration change needed; just plug in the adapter and the phone will switch seamlessly. This is a reliable way to keep the device running if your PoE switch goes down.
Not all versions of this adapter have an LED indicator, so don't rely on that alone. If the phone powers on and works normally, the adapter is functioning. If the phone shows no signs of life and you are certain the outlet is good, try the adapter with another compatible device to confirm.
Yes, this is the exact OEM part that originally shipped with that phone. It will fit and perform identically to the one you lost, with no configuration or setup needed.
No, the PS12V1000US is designed for 110-120V North American outlets. Using it with a passive plug adapter in a 220V country will likely damage the adapter and the connected phone. If you need international use, look for a Yealink adapter with the appropriate input voltage rating.
Absolutely. The adapter provides power independently of the network connection. This is actually the intended setup for the CP935W when not using PoE—the phone gets its data over Wi-Fi and its power from this adapter.

About This Product
The Yealink PS12V1000US is a purpose-built power adapter for a handful of Yealink conference and desk phones, including the CP925, CP935W, VP59, and MP58 WH E2. It is the simplest way to replace a lost or damaged power supply, or to keep a spare on hand in a busy meeting room. For IT managers in the GTA, having a few of these in stock means a dead device in a boardroom can be back online in minutes without hunting for a compatible adapter.
Because this is an OEM part, it delivers exactly the 12V 1A those specific models expect, avoiding the subtle failures or long-term damage that can come from a generic adapter with loose voltage regulation. It is not a universal charger, and it will not power other Yealink phones or third-party devices, so it only makes sense if you already own one of the listed endpoints. In a deployment where those phones run on Power over Ethernet, this adapter is unnecessary—it is purely for AC-powered setups or as a backup when a PoE switch port fails.
A buyer should know that this is a small, lightweight brick with a fixed North American plug. It is not a multi-voltage travel adapter, and it is not rated for outdoor or wet environments. For a single desk phone in a home office, a spare might be overkill; for a company with a dozen CP925 units spread across meeting spaces, having one or two extras is a cheap insurance policy.
