|---|---|
| Usable energy | 247Wh (92% via 12V/USB DC output) |
| Continuous AC output | 600W |
| Surge rating | 1200W |
| Laptop battery | 60Wh |
| Energy per charge | 69Wh |
| Full charges | 3.6 charges |
268Wh × 0.92 = 247Wh usable ÷ (60Wh × 1.15) = 3.6 charges

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).
Tips
- A typical laptop battery holds 50–70Wh. Charging over USB-C PD is more efficient than using the laptop's AC brick.
- Running it from the Bluetti EB3A’s DC port instead of the AC outlet avoids inverter losses: about 19Wh more usable energy.
- The Bluetti EB3A uses LiFePO4 (LFP) cells, rated for thousands of cycles, so running it down daily won’t wear it out quickly.
