Just got a new gadget that does not include a dedicated AC adapter? Then you need to purchase a power supply that matches your device.
An AC adapter essentially converts the mains power AC 110-240V AC into a (usually smaller) DC voltage that small devices needs to operate. Often these are required for charging or powering battery operated devices.
The first thing you want to do is find out what your device needs to operate so inspect the device and look for any labels or symbols that indicate either the voltage or mAh/A. V (sometimes VAC or VCD) indicates the input voltage, whereas mAh/A indicates the current consumption. AC/DC indicates the required voltage type.
Your adapter needs to match the indicated V and equal or be higher than the indicated mAh. In addition, you must ensure that the polarity of the adapter and your device match. Finally, you obviously need to check the plug size of your device and match it to the adapter. Generally, there are two measurements for these types of connectors:
- OD – Outer diameter of the plug.
- ID – Inner diameter of the plug.
If all this sounds complicated, have no fear- AVIVC&EMS has adapters for literally any device and our representatives will be happy to guide you through the process of selecting an adapter suitable for your device.
