Classification: CPC B  H  G | IPC G  H

Claim 12:
13. A jump starter device comprising
a battery;
output terminals,
wherein the output terminals are configured to be connected to any of
connectors in the vehicle with the connectors configured to be connected to terminals of a battery in the vehicle and with the terminals of the battery connected to or disconnected from the connectors,
the terminals of the battery with the terminals of the battery disconnected from the connectors, or
terminals of an external power supply;

a controllable switch,
wherein terminals of the battery are connected to the output terminals through the controllable switch;

a load sensor,
wherein the load sensor comprises a first circuit connected to the output terminals,
wherein the first circuit is connected to the battery through a second circuit,
wherein the first circuit is configured to provide first and second voltage values related to voltages at the output terminals based on first and second statuses of the second circuit,
wherein in the first status, the battery is configured to not provide power to the first circuit,
wherein in the second status, the battery is configured to provide power to the first circuit;

a controller,
wherein the second circuit is coupled to the controller to be controlled by the controller to toggle between the first and second statuses,
wherein the controller is connected to the load sensor to receive the first and second values to determine a connectable condition between the jump starter device and the vehicle,
wherein the controller is connected to the controllable switch,
wherein the controller is configured to turn on the controllable switch when detecting the connectable condition.
