Apple's iPhone charger crams a lot of technology into a small space. Apple went to extra effort to provide higher quality and safety than other name-brand chargers, but this quality comes at a high cost.. In fact, Apple seems to squeeze an awful lot of technology into a very, very small space.

Tinned copper is an easy and effective way of keeping a copper conductor from tarnishing, from becoming oxidized. You've probably seen copper when it is oxidized. It turns green. The Statue of Liberty is a famous example of copper oxidation.ertain formulations of TeflonÂ® are very caustic and can create copper oxide just by being extruded onto a copper wire. Having a tinned copper conductor reduces this effect. One other way we can do this is silver coated copper. When silver oxidizes, that silver oxide is exactly the same conductivity as normal silver.
