The numbers
| Battery capacity | 1024Wh (LFP) |
|---|---|
| Usable energy | 870Wh (85% via AC outlets) |
| Continuous AC output | 1800W |
| Surge rating | 2700W |
| Window AC (5,000 BTU) running watts | 450W |
| Startup watts | 1300W |
| Average draw | 315W |
| Estimated runtime | 2.8 hours |
| Energy per day of typical use | 2.5 kWh |
1024Wh × 0.85 = 870Wh usable ÷ 315W average = 2.8 hours

Recharging with solar
The Bluetti Elite 100 V2 accepts up to 1000W of solar input. In real conditions that harvests about 3.8 kWh on a sunny day (5 peak-sun hours), or about 750Wh with one 200W panel.
Solar can keep up. A window AC (5,000 BTU) uses about 2.5 kWh a day at 8 hours of use, so with enough panels and good sun the Bluetti Elite 100 V2 can run it indefinitely.
Tips
- Small window units draw around 450W while the compressor runs. On hot days it rarely switches off, so expect 60–80% duty.
- You’ll still have about 1350W of AC capacity left for other devices at the same time, though they’ll share the same battery.
- The Bluetti Elite 100 V2 uses LiFePO4 (LFP) cells, rated for thousands of cycles, so running it down daily won’t wear it out quickly.
