The power interface 11 is adapted to be electrically connected to a first device to be powered, such as a cell phone, a notebook computer, a wearable device, and other types of low power electronic devices. In one embodiment, as shown in FIG. 1, the power interface 11 includes both a Type-C interface 111 and a Type-A interface 112. In some embodiments, the power interface 11 may include only a single interface, such as only one of the Type-C interface 111 and the Type-a interface 112. Alternatively or in addition, the power interface 11 may include other types of single or multiple interfaces, as embodiments of the present disclosure are not limited in this regard.
Fig. 2 shows a schematic circuit diagram of a dc wall outlet 100 according to one embodiment of the present disclosure.

In order to prevent the dc wall socket 100 from being burned due to the instantaneous large current, the overcurrent protection circuit can timely open the circuit, thereby protecting other circuit components in the dc wall socket 100 and avoiding the occurrence of safety accidents. In one embodiment, the over-current protection circuit may include a fuse. When high current occurs, the fuse can be instantaneously fused, so that other circuit components are prevented from being damaged by the instantaneously high current. In other embodiments, the over-current protection circuit may include other types of over-current protection devices, which implementations are also within the scope of the present disclosure.
In the event of a temperature rise in the dc wall outlet 100, the thermal protection circuit may timely open the circuit in the dc wall outlet 100 based on the elevated temperature, thereby preventing the temperature of the dc wall outlet 100 from overheating and avoiding damage to other circuit components in the dc wall outlet 100.
In one embodiment, as shown in fig. 2, the protection circuit 13 further includes an anti-reverse circuit 132, and the anti-reverse circuit 132 is connected to the input protection circuit 131. In some cases, the anti-reverse circuit 132 may allow current to pass in the case where the first device to be powered 3 is connected to the power supply interface 11 in the forward direction, thereby allowing power supply to the first device to be powered 3, and the anti-reverse circuit 132 may prevent current from passing in the case where the first device to be powered 3 is connected to the power supply interface 11 in the reverse direction, thereby preventing power supply to the first device to be powered 3. In other cases, the anti-reverse circuit 132 may allow current to pass, allowing power to be supplied to the first device 3 to be supplied, whether the first device 3 is connected to the power supply interface 11 in the forward or reverse direction.

Fig. 4 shows a schematic circuit diagram of a dc wall outlet 100 according to another embodiment of the present disclosure. The dc wall socket 100 shown in fig. 4 is similar in structure to the dc wall socket 100 shown in fig. 2, except that the dc socket unit 2 is connected to a separate second dc input terminal 23 to receive a second dc power input.
