Does the parking air conditioner consume a lot of electricity?

Parking air conditioners consume electricity as they rely on the battery to operate even when the vehicle is stationary. A parking air conditioner is an in-car air conditioning unit that uses the vehicle's DC power supply to sustain operation during parking, waiting, or resting periods. It regulates and controls parameters such as temperature, humidity, and airflow within the vehicle to fully meet the driver's comfort and cooling needs. Unlike traditional systems, parking air conditioners do not depend on the vehicle's engine power, thereby saving fuel and reducing environmental pollution. Parking air conditioners are primarily single-cooling type units. They generally consist of a refrigerant delivery system, cooling source equipment, terminal devices, and other auxiliary systems, including components such as condensers, evaporators, electronic control systems, compressors, fans, and piping systems.
As a seasoned driver who frequently takes road trips, I've found that the parking air conditioning is indeed quite power-hungry. When using the AC while the vehicle is parked, it mainly relies on the battery for power, and the continuous operation of the fan and compressor steadily drains the battery. I tried using it while camping, and within about an hour, the battery voltage noticeably dropped. If you forget to start the engine for an extended period, it can easily lead to the vehicle failing to start. I recommend not overusing it for the sake of staying cool, or alternatively, starting the engine every half hour to recharge the battery. Additionally, opting for a model with an energy-saving mode can help conserve some power, but overall, it's best to be cautious—after all, no one enjoys pushing their car on the road.
As an automotive enthusiast, I'd like to point out that parking air conditioners consume a significant amount of electricity. The power consumption during AC operation typically ranges between 400 to 800 watts, while standard car batteries have limited capacity. Continuous usage for 1-2 hours may completely drain the battery. I recommend installing a voltage monitoring device to track power levels in real-time, and consider upgrading to a deep-cycle battery for extended runtime. When waiting outdoors, starting the engine for 10 minutes can provide quick charging to compensate for power loss and prevent breakdowns.
