An AC adapter is a small device that connects an electronic device to a wall outlet. It enables electricity from the wall outlet to travel through the adapter into the device, thus providing it power and giving it the ability to operate. If your AC adapter breaks, this can be a major problem. Luckily, you can find a replacement from here...
Step 1: Find out what kind of input your ac adapter has. The input is the part of the adapter's cord that plugs into the electronics device. A laptop computer will have a different input than, say, a Game Boy. You can check to see the exact specifications of the input in your electronic device's users manual (on the "Specifications" page), or you can make sure you buy an ac adapter that is specific to your kind of device. It will say what kind of devices it works with on the packaging
Step 2: Make sure the new adapter you buy will provide the proper voltage to the device you are trying to power. This is very important, as providing too little power will not enable the device to work properly and providing too much can damage it permanently. Compare the voltage your electronic device requires (as noted in its user's manual) to the voltage theac adapterprovides (as noted on its packaging).
Step 3:Make sure you get a new adapter with the proper wall plug. Some AC adapters will have a standard two-prong plug, while others will have three. Look at the wall outlet you intend on using the most and see what kind of plug you need. You can plug a two-pronged adapter into a three-pronged wall outlet, but you can't plug a three-pronged adapter into a two-pronged wall outlet.
