SMART CHARGING SYSTEM FOR MOBILE PHONES- METHOD AND SYSTEM TO SAVE ELECTRICAL ENERGY BY ELECTRO-MECHANICALLY DETACHABLE / AUTO CUT OFF MOBILE CHARGER CONTROLLED BY MOBILE PHONE ITSELF

摘要

We claim in this invention that this method and device of smart charger is useful for electrical energy saving by switching off the AC mains supply to the charger by making the charger unplugged from its socket by electronic or mechanical way when the mobile phone batter is fully charged as it happens in normal case that when the mobile phone is fully charged people forget to switch off, remove or unplugged the charger from the AC mains supply and a small power is continuously consumed by the charger circuit. This invention is to save this power.
