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.
It's not a battery charger, regardless of what people call it.
A battery charger would need to have the requred cirutry built-in to be called a battery charger, most of things things do NOT have that.
The USB brick is a power adaptor.Well actually it's a voltage adapter or transformer.
It takes the power from your wall socket as input and provides a 5 or 10 volt output to the device. This is not a power supply unit either.It takes voltage and current. It then converts that voltage and let the connected item whether it be a light bulb batter or computer to draw whatever current the device wants. Although the older ni-cd charges kept the current constant.
The battery is not a PSU either,A battery can be said to be suplying power to the device.
the PMIC (power management integrated circuit) chip in the iPad is a the PSU.That is the unit it is NOT the power supply as it doesn't have any power. Some don't think there's a need to be specific. The ipad can NOT be charged with just the PMIC.
It takes the power from either the battery *or* the power adapter and provides electrical current to the load (i.e. the iPad).Yep that's correct although it actually suplies voltage and allows the ipad to take what current it requires if you wan tto know what power it's taking you muiliply the voltage X the current, if either are 0 then yuo aren't supplying power.
Few would call a PMIC a PSU,nospam might ;-) sorry nospam
