20W and 30W represent the maximum power carrying capacity of the socket. The specific differences are as follows:
< br >
20W socket: The maximum power carrying capacity of this socket is 20W, which is suitable for some low-power electrical equipment, such as mobile phone chargers, small electronic devices, etc. If you need to charge or power these low-power devices, a 20W socket is a good choice.
30W socket: In contrast, the maximum power carrying capacity of 30W socket is higher, and it is suitable for some medium-power electrical equipment, such as computers, televisions, audio, etc. If you need to charge or power these medium-power devices, a 30W socket can provide more stable and reliable power support.
It should be noted that when using the socket, the appropriate socket should be selected according to the power requirements of the device. If the power of the device you use exceeds the maximum carrying capacity of the socket, it may lead to safety problems such as overload and overheating of the socket. Therefore, when using a socket, be sure to check the power requirements of the device and select the appropriate socket to ensure safe use.
The difference is mainly in power and charging speed.
The power of the Bull 20w charging head is 20W, which is suitable for fast charging of ordinary mobile phones, tablets and other devices, and the charging speed is slow.
The Bull 30w charging head has a power of 30W, which can support higher power output, and is suitable for fast charging of devices such as high-end mobile phones and laptops, with faster charging speed.
Therefore, if you need to charge a high-end mobile phone or laptop, it is recommended to choose the Bull 30w charger, otherwise choose the Bull 20w charger.
At the same time, pay attention to the matching between the charging head and the device to ensure that the device will not be damaged.
The difference between 20W and 30W is the output power, 30W has a higher output power, can support more devices, support multiple devices at the same time, can meet more needs.
