A larger 15,000 BTU model will obviously pull more electricity than a smaller 10,000 BTU model, requiring a more robust electrical system to handle the load. BTU Rating and Energy Correlation The British Thermal Unit (BTU) rating of an air conditioner is directly proportional to its power consumption.

Calculating Wattage and Daily Consumption To translate amperage into a more familiar metric, you calculate the wattage. Most roof-mounted units require a substantial surge of current to start the compressor, followed by a lower draw to run it.
A typical car battery provides around 60-80 amp-hours, which is insufficient to start a large RV AC unit. Efficiency Ratings and Smart Usage.

Even then, running an air conditioner will drain a standard battery setup in just a few hours without a recharge source. Since air conditioners cycle on and off, you cannot simply multiply this by the total number of hours you run it.
