The numbers
| Battery capacity | 768Wh (LFP) |
|---|---|
| Usable energy | 653Wh (85% via AC outlets) |
| Continuous AC output | 1000W |
| Surge rating | 1500W |
| Chest freezer running watts | 100W |
| Startup watts | 700W |
| Average draw | 35W |
| Estimated runtime | 19 hours |
| Energy per day of typical use | 840Wh |
768Wh × 0.85 = 653Wh usable ÷ 35W average = 18.7 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 chest freezer uses about 840Wh a day at 24 hours of use, so with enough panels and good sun the Bluetti AC70 can run it indefinitely.
Tips
- Chest freezers are well insulated, so their compressor runs less than an upright fridge's. Keep the lid closed during an outage.
- You’ll still have about 900W 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.

FAQ
Will the Bluetti AC70 run a chest freezer overnight?
Yes. Eight hours uses about 280Wh, roughly 43% of the Bluetti AC70’s usable capacity.
How long does the Bluetti AC70 take to recharge with solar?
With its maximum 500W of solar input it refills in about 2 hours of strong sun. With a single 200W panel, expect about 5.1 hours of full sun.
