The numbers
| Battery capacity | 768Wh (LFP) |
|---|---|
| Usable energy | 707Wh (92% via 12V/USB DC output) |
| Continuous AC output | 1000W |
| Surge rating | 1500W |
| Smartphone battery | 15Wh |
| Energy per charge | 17Wh |
| Full charges | 41 charges |
768Wh × 0.92 = 707Wh usable ÷ (15Wh × 1.15) = 41 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
- Most phones hold 12–19Wh. Charge from a USB port rather than the AC outlet to skip inverter losses.
- 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.
