I am using it to add a branch socket of a car. When used as a power supply for smartphones or drive recorder, the socket runs short and I am using it to increase the number of sockets I have been using.
It is a repeat purchase. Even though it is reasonable, it seems to be robust with firm making. It is also excellent to let the length of the main body connection plug be 3 stages. The energizing lamp is also gentle blue and there is no discomfort.
