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 | 25 hours |
| Wi-Fi router + modem | 15 W | 17 hours |
| CPAP machine (no humidifier) | 40 W | 6.2 hours |
| Starlink (standard kit) | 50 W | 5.0 hours |
| Box fan | 50 W | 5.0 hours |
| Laptop | 60 W | 4.2 hours |
| 55" LED TV | 100 W | 2.5 hours |
| Full-size refrigerator (avg) | 150 W | 1.7 hours |
| Mini fridge (avg) | 60 W | 4.2 hours |
| Coffee maker | 900 W | Exceeds 300W output |
| Microwave (700W cooking) | 1000 W | Exceeds 300W output |
| Space heater | 1500 W | Exceeds 300W output |
For CPAP users: that's roughly 0.8 nights of sleep (8h/night, humidifier off).

FAQ
How long will the Jackery Explorer 300 run a refrigerator?
Around 1.7 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 Jackery Explorer 300 use a LiFePO4 battery?
No. It uses NMC lithium-ion cells rated for about 500 cycles to 80% capacity, which is a shorter service life than modern LiFePO4 models.
What solar panels work with the Jackery Explorer 300?
Any panel (or array) within its 12-30V MPPT voltage window and up to 90W, connected via DC8mm. Staying inside the voltage window matters more than matching wattage.
How fast does the Jackery Explorer 300 recharge from a wall outlet?
About 120 minutes from 0 to 80% on AC power.
