We use batteries to power a lot of our electronics. But there are some battery powered devices that don’t necessarily need to be portable all the time. One example is my son’s battery powered swing. It can be moved around but it usually stays in the same general area. In cases like these it might be nice to power these devices with an AC adapter and save the batteries. So in this project, I am going to show you how you can use an old power adapter to power your electronics in place of batteries. I will share how to modify the adapter and two different ways to connect it to your electronic devices.
