The objective of this Public Consultation is to establish the minimum requirements to be demonstrated in the conformity assessment and approval, with the National Telecommunications Agency, of a charger used in a cell phone.

The requirements set out in this document are applicable to the following cell phone chargers:

a) portable chargers whose power supply is the alternating current power grid (e.g. home charger).

b) portable chargers powered by a direct current source (e.g. vehicle charger).

c) inductive chargers, regardless of the type of power supply (alternating current or direct current).

d) Special-purpose USB interfaces (ports) for powering electronic devices, without data transmission functionality, regardless of the type of power supply.

Standards applicable for Vehicular cellphone chargers

ISO 10605/2008: Road Vehicles – Test methods for electrical disturbances from electrostatic discharge
