Abnormal protection such as headset socket (beyond the upper limit when working voltage, current and effective power, to prevent interference caused by false positives), automatic power-off circuit safety protection; a timing switch device for intelligent charging and intermittent control timing switch of the timer switch can be set to 10 switch time, and can set the number of days per week loop;
1, real-time display of the current voltage, current, power (active power) on the socket;
2, beyond the upper limit (voltage, power, etc.) after a certain period of time (to prevent interference caused by false positives), automatic alarm (voice), and automatically power-off, after the protection of circuit security;
3, show the total power consumption, and automatically count the amount of electricity spent in an hour, how much electricity the day before, how much electricity was used in the last month;
Whether the earphone socket is good or not, look at the copper parts. If you see through the socket is bright yellow, then give it up. Brass easily rust, soft texture, a long time, contact, electrical conductivity will decline. If the copper color is purple, it is better, copper is more tough, not easy to rust. Direct view is not enough, but also generally open to see. Many sockets are sockets, here with copper, inside with brass, equally easy to rust.
