This high-quality, low-noise power supply adaptor by myVolts has an output of 12V DC and 2A max, and center positive polarity. Tip: 2.5 x 5.5, straight.
It's suitable for any device that has a power requirement matching this specification.
If your device has a current requirement lower than 2A that's fine, only the current required by the device is drawn by the device.
So a device that needs, for example, 500mA (or 0.5A) current will be perfectly served by a 1000mA (or 1A) power adaptor.
