The numbers
| Battery capacity | 2048Wh (LFP) |
|---|---|
| Usable energy | 1741Wh (85% via AC outlets) |
| Continuous AC output | 2200W |
| Surge rating | 4800W |
| Window AC (8,000 BTU) running watts | 700W |
| Startup watts | 2000W |
| Average draw | 490W |
| Estimated runtime | 3.6 hours |
| Energy per day of typical use | 3.9 kWh |
2048Wh × 0.85 = 1741Wh usable ÷ 490W average = 3.6 hours

Recharging with solar
The Bluetti AC200MAX accepts up to 900W of solar input. In real conditions that harvests about 3.4 kWh on a sunny day (5 peak-sun hours), or about 750Wh with one 200W panel.
Solar can’t fully keep up. A window AC (8,000 BTU) uses about 3.9 kWh a day at 8 hours of use, more than the Bluetti AC200MAX’s best-case solar harvest. Solar will stretch the runtime but not sustain it.
Tips
- Mid-size window units need a stout inverter to survive the compressor start.
- You’ll still have about 1500W of AC capacity left for other devices at the same time, though they’ll share the same battery.
- The Bluetti AC200MAX uses LiFePO4 (LFP) cells, rated for thousands of cycles, so running it down daily won’t wear it out quickly.
