iPhone’s Charger Contains Complex And Innovative Circuitry

Apple fans know their love comes at a price, as Apple's devices and accessories can be quite expensive compared to other products. With this in mind, Ken Shirrif decided to look for the quality that justifies the price in a common accessory - the iPhone wall charger.

After taking apart the iPhone charger, he came up with a full analysis of the circuit boards, isolation and the transformer.

"Apple's power adapter is clearly a high-quality power supply designed to produce carefully filtered power. Apple has obviously gone to extra effort to reduce EMI interference, probably to keep the charger from interfering with the touchscreen," said Ken Shirrif on his website.

He discovered that Apple's charger is far ahead of the typical accessories in this class. The printed circuit boards are technologically advanced and extremely small, compared to other models.

After 2008, when Apple was forced to recall iPhone chargers because of manufacturing issues, the company began to focus on the chargers' safety. Since then, the company has redesigned the chargers.

Tests reveal that they are now more secure compared to similar accessories from other manufacturers.
