The invention relates to the mobile charging field, in particular to a safe multi-directional charger.
Both charger and charging wire may become faulty or be aging over time which leads to abnormal charging of electronic equipment, the magnitude of output current of charger may become unsafe, and the current output to the electronic equipment to be charged does not meet the current magnitude requirements of electronic equipment. The existing wireless charger includes a charging head directly connected with AC power and a coil for generating induced current. The electronic equipment is provided with an induced coil corresponding to the coil. The charger may become faulty or be aging after it is used, so the electronic equipment cannot be charged normally. Normal charging means that the current of charging head flowing to electronic equipment is within the standard range. However, during use the electronic equipment may show it is being charged but actually it is not normally charged as the current flowing from the charger to the electronic equipment is too weak, but the user cannot judge the safety potential hazard such as charging equipment damage due to abnormal current flowing from the charging head to the electronic equipment. The existing charger cannot be charged when the power is exhausted or the power supply is not directly connected. Single charger can only charge for single equipment but cannot meet the requirement for simultaneous charging of more than one charger.
The invention can solve the existing technical problems and aims to judge whether the charging current is in safe charging range by checking the magnitude of current of electronic equipment displayed on the current display.
