The Advantages of USB Powered Adapters:

• Convenience - With an adapter, you only have to bring one charger instead of several. Most people carry at least two devices that require routine charging, and with a USB power adapter, you can attend to more than one device's needs with only one component
• Fewer Components - When we think of plugging in a USB powered device, we usually think of plugging into a computer. But with a USB powered adapter, you can cut out the middle component. The powered adapter does not need a computer to funnel the power to the device
• Charging Devices - If your computer has a limited number of available USB ports, or if you are away from a computer, some USB adapters are able to charge two devices at the same time
• Economic Replacement - The proliferation of new electronic devices means an abundance of accompanying cords and chargers that may get lost or damaged. Often, you can use a USB adapter to replace the original charger for your device

How to Test a Power Adapter:

• Examine your power adapter. Every power adapter will have the input voltage and amperage requirements printed on it, as well as the output voltage and amperage rating. We'll be testing the output of the power adapter, so write down the specs. An example would be this, taken from a laptop power adapter: Output - 19.5V....3.34 amps. We'll measure the output of the power adapter with a multimeter --a very handy tool for anyone working with electronics. A multimeter can measure voltage, current, power output and resistance of electrical circuits by touching the electrical circuits or device with a set of probes. See Additional Resources for a good tutorial on multimeters
• Set your multimeter to the proper range for measuring the output of your power adapter. Take into account the voltage and the amperage you'll be measuring. Consult the manual for specifics on how to set your particular model of multimeter
• Check the data plate of your power adapter to find out which portion of the plug is positive and which is negative. For example, on some power adapter plugs, the outer shell of the plug is positive, while on others it's negative
• Touch the probes of your multimeter to the corresponding portions of the power adapter's plug and note the readout. Compare that with the rated output of the power adapter. If it varies significantly, replace the power adapter

Methods to Check Power Adapter Output:

• Unplug the power adapter from any electronic device to which it's connected. Leave it plugged into its power source
• Find the input and output information on your power adapter. This is normally found on a thicker, non-cord part of the adapter. Next to the word "Output," you will see a number with a "V" beside it. That's the output in volts. Make note of this number. Near the output information, you'll also see a diagram that shows which part of the plug is negative and which is positive. With most, the inside of the plug is positive, but be sure to check because sometimes this varies
• Check your multimeter's manual for instructions on how to set the multimeter to the appropriate voltage. The method varies between brands of multimeter
• Touch the probes of your multimeter to the appropriate locations on the power adapter's plug. One probe should be inside the plug; the other should be touching its exterior
• Read the voltage shown on the multimeter's screen. It should be close to the number you made note of in Step 2. If it's too far off, you know there's a problem
