How to Choose Power Adapters For You Device
Power adapters seem simple enough, right? You plug one end into the wall and the other end into your device. What some may fail to consider are all the other options which may help save energy, time and space. When considering a Power adapter, you need to know what type of voltage your device needs: AC or DC. You should also look for a recommended charging current listed on the device you are powering. From there, decide whether you want regulated or unregulated, and linear or switching.
Finally, take a look at your device's plug socket and match it with the supply's DC output connector. The most common types of connectors are 2.1mm inner diameter x 5.5mm outer diameter female, 2.5mm inner diameter x 5.5mm outer diameter female, 3.5mm male, and even screw terminal connections (Remember to also match center positive or center negative plugs).
If your device uses a plug connector, you can find out what size plug your device needs by using some calipers and measuring the inside diameter as well the outside diameter. Traditional rulers can also be used, but keep in mind that they usually aren't very accurate and may not measure in millimeters, which is the industry standard. Adapter kits are also available which contain several common size plugs.
The "HGD" Power adapters are also very popular because they are smaller and take up less room. If you're using a power strip, you don't want a Power adapter to take up 2 or 3 of your outlet spaces. Also take into consideration the different agency approvals. CEC approved Power adapters have the highest energy efficiency levels, which may cost more up front but save you in long-term energy costs.
Finding A adapter that provides enough current to your device is critical for efficient charging. Your device will draw the appropriate amount of current from the adapter, but if the adapter cannot provide enough current, the device will take longer to fully charge. Be sure to choose an adapter that is able to supply the amount of current listed on your device.
For your convenience, there are also interchangeable AC-DC regulated switching Power adapters. These adapters have AC input connectors that can be swapped for use in various countries. Plug types include: USA, European, United Kingdom, and Australian.
So next time you're searching for a Power adapter, keep in mind all of the different combinations available. Doing your research and preparation can save you any hassle in the future.
