The numbers
| Battery capacity | 268Wh (LFP) |
|---|---|
| Usable energy | 228Wh (85% via AC outlets) |
| Continuous AC output | 600W |
| Surge rating | 1200W |
| Window AC (5,000 BTU) running watts | 450W |
| Startup watts | 1300W |
| Average draw | 315W |
| Estimated runtime | 43 minutes |
| Energy per day of typical use | 2.5 kWh |
268Wh × 0.85 = 228Wh usable ÷ 315W average = 0.7 hours

Recharging with solar
The Bluetti EB3A accepts up to 200W of solar input. In real conditions that harvests about 750Wh on a sunny day (5 peak-sun hours).
Solar can’t fully keep up. A window AC (5,000 BTU) uses about 2.5 kWh a day at 8 hours of use, more than the Bluetti EB3A’s best-case solar harvest. Solar will stretch the runtime but not sustain it.
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 150W of AC capacity left for other devices at the same time, though they’ll share the same battery.
- The Bluetti EB3A uses LiFePO4 (LFP) cells, rated for thousands of cycles, so running it down daily won’t wear it out quickly.

FAQ
Will the Bluetti EB3A run a window AC (5,000 BTU) overnight?
No. At about 315W average it runs out after 43 minutes. For a full night you need at least 3000Wh of capacity.
How long does the Bluetti EB3A take to recharge with solar?
With its maximum 200W of solar input it refills in about 1.8 hours of strong sun. A single 200W panel is enough to max out its solar input.
Which power station can run a window AC (5,000 BTU)?
The EcoFlow River 2 Pro (768Wh, 800W output) can, for about 2.1 hours. See the comparison table below for more options.
