In practice, gallium nitride has a number of advantages that people like to take with them when it comes to chargers:
- They can charge very quickly with high power
- The charging power is often sufficient for several devices at the same time
- The power supplies themselves do not heat up that much
- Fast chargers can be made more compact
A disadvantage is that the GaN fast chargers are still expensive in comparison. Also, while the devices are compact, that doesn’t mean they’re lightweight. If you have a GaN power supply in your hand, you are often surprised at how heavy the little things are.
Also, even with GaN models, third-party chargers may not be able to cope with device manufacturers’ proprietary charging techniques. This means that a notebook may not charge at full power, even though the power supply unit could actually provide enough power.
The bottom line is that GaN power supplies have what it takes to be a charger for everything in the future. Not only would that be handy when traveling, but also on your desk.
