Frequently Asked Questions (FAQ)
What do I need an 18V 1A plug-in power supply for?
An 18V 1A plug-in power supply is needed to power electronic devices with an operating voltage of 18 volts and a maximum current requirement of 1 ampere, which use a 5.5/2.1mm barrel jack connector.
Can I use an 18V power supply for a device that requires 12V?
No, you should not do that. Using an 18V power supply for a 12V device can lead to overvoltage and permanently damage the device.
What does 5.5 / 2.1mm connector mean for a power supply?
The specifications 5.5 / 2.1mm refer to the dimensions of the barrel connector: 5.5mm is the outer diameter and 2.1mm is the inner diameter of the connector.
How do I know if the polarity of my device matches the power supply?
The polarity is usually indicated on the device or the original power supply with a symbol (circle with a dot in the middle, plus and minus signs). Universal power supplies typically have a standard polarity (often positive inside, negative outside), which should be checked before connecting to avoid damage.
Is this 18V 1A power supply suitable for PoE injectors?
Some PoE injectors, especially for certain WiFi devices or IP Cameras, may require an 18V power supply. However, it is crucial to check the exact voltage and current requirements of the specific PoE injector as well as the connector type, as not all PoE injectors use 18V or this connector.
Can I use this power supply for a DIY electronics circuit that requires 18V?
Yes, if your DIY circuit requires a stable 18V DC voltage with a maximum current consumption of 1 ampere and is designed for the 5.5/2.1mm barrel connector, this power supply can be used. Pay attention to the correct polarity.
