RadioShack 9 V Multipurpose AC to DC Adapters

Why Should I Choose a 9 V Multipurpose AC-to-DC Adapter

A Radio Shack AC-to-DC adapter can serve as a replacement or backup power supply for most of your electronic gadgets. The regulated, filtered output reduces hum and distortion. So often it happens that you have to continuously replace batteries on a number of your devices. This is where a 9 V multipurpose AC adapter can come in handy. The adapter is really an external power source. When the adapter is plugged into a mains supply, it can sometimes charge the battery while at the same time supplying power to the device. It is essentially a charger that converts 120 V AC to 9 V DC.

How do I Choose the Correct Adapter?

Before choosing an AC-DC adapter, first look for any specification plates, labels or any symbols that indicate the power requirements of your device. These requirements should be matched to the adapter, as follows:

  • The adapter output voltage, in this case 9 V DC, should not be more than the voltage requirement of your device. The voltage rating of your device should never be exceeded.
  • Make sure that the current output of the RadioShack AC adapter, indicated by mAh or A, is greater or equal to the devices current rating.
  • Plug-in the AC adapter to your device and make sure that the plug fits properly and that the polarity is correct.
