Quick Answer
Apartment mini splits usually draw 400-1,200 W and often use 3-8 kWh/day.
Detailed Explanation
Shared walls can reduce heat gain, while top floors and west exposure increase runtime. See How Many Watts Does a Mini Split Use and What Size Generator for Apartment Backup.
Watt Table
| Scenario | Running Watts | Daily kWh |
|---|---|---|
| Studio | 400 - 700 W | 3 - 4.5 |
| 1-bedroom | 600 - 950 W | 4 - 6 |
| Top-floor hot | 850 - 1,200 W | 6 - 8 |
Calculation Example
800 W x 5.5 h/day = 4.4 kWh/day.
