The part that plugs into the wall is the power supply unit or PSU and adapter combined, because it adapts the mains power to DC that the laptop uses to run the laptop and charge the battery. Some call them power bricks.

so you agree that it's called a power supply, although it does have other names too.

Eric Stevens
Like 'battery charger'.

nospam
nope.

a battery charger does just that, charge batteries, usually removing the battery from the device and inserting them into the charger.

that's different than a power supply, which powers the device and which may also charge a battery while the battery is still in the device.

Wait a minute! You've said in another post that people call them different things, and that's OK. So if that's OK, then calling the power adapter a "battery charger" is perfectly legitimate by your rules. If it's used to charge the battery, calling it a "battery charger" is logical.

I'd bet that there are more people who call the Apple device a "battery charger" than there are who call it a "power supply". By a million to one.

I can't prove it, though, since I don't have plans to fly anywhere and can't do a survey at the moment.
