Mobile phone charger


Most mobile phone chargers are not really chargers, only adapters that provide a power source for the charging circuitry which is almost always contained within the mobile phone. Mobile phones can usually accept relatively wide range of voltages, as long as it is sufficiently above the phone battery's voltage. However, if the voltage is too high, it can damage the phone. Mostly, the voltage is 5 volts or slightly higher, but it can sometimes vary up to 12 volts when the power source is not loaded.

Battery chargers for mobile phones and other devices are notable in that they come in a wide variety of DC connector-styles and voltages, most of which are not compatible with other manufactuers' phones or even different models of phones from a single manufacturer.

Users of publicly accessible charging kiosks must be able to cross-reference connectors with device brands/models and individual charge parameters and thus ensure delivery of the correct charge for their mobile device. A database-driven system is one solution, and is being incorporated into some of the latest designs of charging kiosks.



There are also human-powered chargers sold on the market, which typically consists of a dynamo powered by a hand crank and extension cords. There are also solar chargers.

China and other countries are making a national standard on mobile phone chargers using the USB standard.

Starting in 2010, Apple, Nokia, Motorola, Samsung and RIM will begin making handsets with a standard phone charger based on the micro-USB connector.

On October 22 2009 the International Telcommunication Union announced a standard for a universal charger for mobile handsets.

Addition
The concept of unified chargers for mobile phones was originally developed and launched by Dr. Solomon Passy, ex-Foreign Minister of Bulgaria, and his wife Gergana Passy - EU Minister. Following their proposition, batteries preventing their urgent call, they initiated a massive campaign in Sofia and Brussels, and urged the European Commission to abide by its eco-design policies and adopt legislation to unify mobile phone chargers, on the USB standard. The Passys' strategy later involved the GSM Association and the International Telecommunications Union, the UN telecom arm, whose blessing to the standardisation is expected to materialise the plan by 2010. Eventually the major maufacturers (Motorola, Nokia, Sony Ericsson, Samsung, Apple) accepted the Passys' solution and are currently in the phase of implementation.
