What can it run, and for how long?
Estimates assume ~85% inverter efficiency and average running wattage. Motor-driven appliances also need surge headroom.
| Appliance | Typical draw | Estimated runtime |
|---|---|---|
| LED bulb | 10 W | 3 days |
| Wi-Fi router + modem | 15 W | 44 hours |
| CPAP machine (no humidifier) | 40 W | 16 hours |
| Starlink (standard kit) | 50 W | 13 hours |
| Box fan | 50 W | 13 hours |
| Laptop | 60 W | 11 hours |
| 55" LED TV | 100 W | 6.5 hours |
| Full-size refrigerator (avg) | 150 W | 4.4 hours |

FAQ
How long will the Bluetti AC70 run a refrigerator?
Around 4.4 hours for a full-size refrigerator averaging 150W, assuming ~85% inverter efficiency. Actual runtime depends on the fridge's compressor duty cycle and ambient temperature.
Does the Bluetti AC70 use a LiFePO4 battery?
Yes. It uses LiFePO4 (LFP) cells rated for about 3,000 cycles to 80% capacity — roughly 8+ years of daily cycling.
What solar panels work with the Bluetti AC70?
Any panel (or array) within its 12-58V MPPT voltage window and up to 500W, connected via DC7909 (MC4 cable included). Staying inside the voltage window matters more than matching wattage.
How fast does the Bluetti AC70 recharge from a wall outlet?
About 45 minutes from 0 to 80% on AC power.
