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

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.

nospam
no, because it's not a battery charger. where do you put the batteries into it? you don't.

all it does is supply power to whatever is plugged into it.

the battery charging circuitry is actually in the device, not what you plug into the wall.

that power can be used to charge batteries (if connected to a charger) or it can be used to power many other devices, such as an led lamp.

if you plug <http://www.thinkgeek.com/product/5a84/>into what you're calling a battery charger, where are the batteries that are being charged? hint: there aren't any.

it's just a +5v regulated power supply and can be used for a lot of different things.
