What can the Explorer 300 run?
Estimated time running one device on its own, at 85% usable capacity and with 10% power headroom. To combine devices, use the runtime calculator.
“Borderline” means the station’s rating is within 10% of what the device needs, so it depends on your exact appliance.

Questions
How long will the Jackery Explorer 300 run a refrigerator?
It can’t reliably start a typical full-size refrigerator. The compressor’s start-up surge (about 1,200 W) exceeds its 500 W peak output.
Can the Jackery Explorer 300 run a microwave?
No. A 1,000 W microwave draws around 1,500 W from the outlet, more than its 300 W continuous output.
How long does the Jackery Explorer 300 take to charge?
About 270 minutes from a wall outlet (manufacturer figure). With solar at its 90 W maximum input, a full charge takes about 3.3 hours of full sun, or about 4.7 hours at typical real-world panel output.
What battery does the Jackery Explorer 300 use and how long will it last?
It uses NMC lithium-ion cells rated for 500 charge cycles, about 147 kWh of total delivered energy. This is far fewer cycles than LiFePO4 rivals, which matters if you use it daily.
