Here is an example comparing a 200 W power supply designed with GaN technology to a 200 W power supply using silicon technology. The power supply using GaN technology is half of the size and only three quarters of the weight of the power supply designed using silicon technology. The smaller size and lighter weight is obviously an advantage for products which are carried around, such as laptop computers, but also is an advantage for many other products. The smaller power supplies occupy less desk, shelf or floor space and the lighter weight of the power supplies makes them easier and less expensive to ship and less dangerous when they fall.
