types of overload protection. First level of protection: When any of the DC sockets exceeds the maximum

current limit or the output of any AC sockets exceeds the maximum AC power output (Overload of 1-10%

for 10min; overload of 11-20% for 1min; overload of 21-50% for 10s; overload of 51-100% for 100ms), and the

car power output exceeds the maximum current, the overload indicator and the indicator of the

corresponding socket will ﬂash at the same time for 15s. Power supply to the socket will be cut o, while

other sockets will continue to work. Second level of protection: When the power output from any DC or AC

sockets or the car power outlet exceeds the maximum power output of the battery, the overload indicator
