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.
