The iPad AC adapter is a type of power supply – typically those that are embedded in an over-sized AC plug. Other names include plug pack, plug-in adapter, adapter block, domestic mains adapter, or power adapter. Informal terms include wall wart, wall cube and power brick. These are typically packaged with electrical devices that do not contain their own power supply. By separating the power supply from the main body of the electronic device, it can be made more compact and lighter. Any heat dissipated by the power supply is outside the device, so it can run cooler. Using standardized commodity external power supplies can simplify regulatory approval for sale in various countries; only the power supply itself needs to be tested for national standards compliance, instead of a whole device.
Originally iPad AC adapters were linear power supplies, containing a transformer to convert the mains electricity voltage to a lower voltage, a rectifier to convert it to pulsating DC, and a filter to smooth the pulsating waveform to DC, with residual ripple variations small enough not to affect the device being powered. Size and weight of the device was largely determined by the transformer, determined by the power output and mains frequency. Ratings over a few watts made the devices too large to be supported off a wall outlet.
