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 | 41 hours |
| CPAP machine (no humidifier) | 40 W | 15 hours |
| Starlink (standard kit) | 50 W | 12 hours |
| Box fan | 50 W | 12 hours |
| Laptop | 60 W | 10 hours |
| 55" LED TV | 100 W | 6.1 hours |
| Full-size refrigerator (avg) | 150 W | 4.1 hours |
| Mini fridge (avg) | 60 W | 10 hours |
| Coffee maker | 900 W | Exceeds 800W output |
| Microwave (700W cooking) | 1000 W | Exceeds 800W output |
| Space heater | 1500 W | Exceeds 800W output |
For CPAP users: that's roughly 1.9 nights of sleep (8h/night, humidifier off).

FAQ
How long will the Bluetti EB70S run a refrigerator?
Around 4.1 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 EB70S use a LiFePO4 battery?
Yes. It uses LiFePO4 (LFP) cells rated for about 2,500 cycles to 80% capacity — roughly 7+ years of daily cycling.
What solar panels work with the Bluetti EB70S?
Any panel (or array) within its 12-28V MPPT voltage window and up to 200W, connected via DC7909 (MC4 cable included). Staying inside the voltage window matters more than matching wattage.
How fast does the Bluetti EB70S recharge from a wall outlet?
About 180 minutes from 0 to 80% on AC power.
