I have already a Micro-USB charger. Could I use it to charge all mobile phones with a Micro-USB connector?

Some manufacturers already provide chargers with a Micro-USB connector but those chargers were produced for specific mobile phones and may not be suitable for charging all kinds of mobile phones with a Micro-USB connector.
The development of European Standards (including IEC/EN62684) was needed to ensure the compatibility and the functionality of the new generation of Micro-USB chargers and only new chargers which comply with the new European Standards will be considered as a “common charger”.
