A 12-volt adapter allows you to run DC powered devices such as a cell phone charger, laptop or audio and video equipment, by plugging them into an AC outlet. There are several 12-volt adapters on the market, so it is important to get the right one. You want to make sure that the amps are correct and that the plug fits the outlet in your home. If you don't have the adapter and need to replace it, universal adapters will take some of the guessing away during installation, since you won't need to worry about having the right adapter.
Instructions
1. Take the AC power cord with two prongs from the adapter and plug it into the AC power supply. Most likely the AC supply will be the electricity wall jack in your home.
2. Plug the other end of the AC power cord into the adapter.
3. Plug the DC power into you device. On the end of the DC cord is a plug that can vary in size. If the tip doesn't fit your device, don't force it; you have the wrong adapter.
