The numbers
| Battery capacity | 768Wh (LFP) |
|---|---|
| Usable energy | 707Wh (92% via 12V/USB DC output) |
| Continuous AC output | 1000W |
| Surge rating | 1500W |
| 12V car fridge running watts | 45W |
| Startup watts | 60W |
| Average draw | 18W |
| Estimated runtime | 39 hours |
| Energy per day of typical use | 432Wh |
768Wh × 0.92 = 707Wh usable ÷ 18W average = 39.3 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 12V car fridge uses about 432Wh a day at 24 hours of use, so with enough panels and good sun the Bluetti AC70 can run it indefinitely.
Tips
- Compressor coolers like Dometic, ICECO and BougeRV plug into the 12V car port, which skips inverter losses entirely.
- 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.

FAQ
Will the Bluetti AC70 run a 12V car fridge overnight?
Yes. Eight hours uses about 144Wh, roughly 20% 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.
