The present disclosure is a hydraulic jack including a housing that supports a reservoir, a motor, a pump assembly, and a lift assembly. The housing includes a lift portion in which the lift assembly is at least partially supported, and a power supply portion configured to removably receive a power supply. The motor is configured to receive power from the power supply. The pump assembly receives a rotational output from the motor to generate a flow of hydraulic fluid from the reservoir. The lift assembly is extendable between a retracted position and an extended position in response to the flow of hydraulic fluid and is configured as a three-stage lift assembly with a first stage that extendable in a first manner, and second and third stages extendable in a second manner.
