The numbers
| Battery capacity | 768Wh (LFP) |
|---|---|
| Usable energy | 653Wh (85% via AC outlets) |
| Continuous AC output | 1000W |
| Surge rating | 1500W |
| Mini fridge running watts | 85W |
| Startup watts | 450W |
| Average draw | 34W |
| Estimated runtime | 19 hours |
| Energy per day of typical use | 816Wh |
768Wh × 0.85 = 653Wh usable ÷ 34W average = 19.2 hours

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.
Solar can keep up. A mini fridge uses about 816Wh a day at 24 hours of use, so with enough panels and good sun the Bluetti AC70 can run it indefinitely.
Tips
- Compact dorm-style fridges run small compressors that cycle about 40% of the time.
- You’ll still have about 915W of AC capacity left for other devices at the same time, though they’ll share the same battery.
- The Bluetti AC70 uses LiFePO4 (LFP) cells, rated for thousands of cycles, so running it down daily won’t wear it out quickly.
