Your laptop power adapter states that it is “auto-switching.” What does this mean?
A) The power supply will charge the laptop battery and automatically stop when the battery is fully charged
B) The power supply will automatically use 110 volts or 220 volts depending on the power source
C) The power supply will provide both 110 volts and 220 volts simultaneously while the laptop is in use or charging
D) The power supply will automatically switch between AC and DC
E) The power adapter will switch languages depending on its geographical location
The answer: B) The power supply will automatically use 110 volts or 220 volts
An auto-switching power supply can be used almost anywhere in the world, because it can use both 110 volt power sources or 220 volt power sources. This means that you can travel to another country and use a simple connector adapter on the end of your cable to plug into the foreign power source. No additional voltage conversion is required when you’re using an auto-switching power supply!
