As you all have probably noticed, there are two mainstream ways that electronic devices are powered– by plugging its cord into a wall or through the use of batteries.

While this makes sense for large devices like a welding machine, you’ll still find most table top fans need to be plugged into the wall socket. What is preventing this change from happening?
