The numbers
| Battery capacity | 768Wh (LFP) |
|---|---|
| Usable energy | 707Wh (92% via 12V/USB DC output) |
| Continuous AC output | 1000W |
| Surge rating | 1500W |
| Laptop battery | 60Wh |
| Energy per charge | 69Wh |
| Full charges | 10 charges |
768Wh × 0.92 = 707Wh usable ÷ (60Wh × 1.15) = 10.2 charges

Recharging with solar
The Bluetti AC70 accepts up to 500W of solar input. In real conditions that harvests about 1.9 kWh on a sunny day (5 peak-sun hours), or about 750Wh with one 200W panel.
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 AC70’s DC port instead of the AC outlet avoids inverter losses: about 54Wh more usable energy.
- The Bluetti AC70 uses LiFePO4 (LFP) cells, rated for thousands of cycles, so running it down daily won’t wear it out quickly.
