Jackery Explorer 3000 Pro sizing guide
Three kilowatt-hours for multi-day outages and heavier loads, on wheels. Here's exactly what it runs, how long, and which outages it covers — computed, not marketed.
~2.4 h AC; up to 1200 W solar · 64 lb · 4× AC, USB-A/C.
What the Explorer 3000 Pro runs — and for how long
| Appliance | Running | Runs it? | Approx. runtime |
|---|---|---|---|
| Refrigerator (modern) | 150 W (1,200 W surge) | yes | ~52 h |
| Chest Freezer | 100 W (1,000 W surge) | yes | ~78 h |
| CPAP Machine (no humidifier) | 40 W | yes | ~68 h |
| CPAP with Heated Humidifier | 60 W (95 W surge) | yes | ~57 h |
| Oxygen Concentrator | 350 W (600 W surge) | yes | ~7.8 h |
| Space Heater (1500 W) | 1,500 W | yes | ~1.8 h |
| Window AC (8,000 BTU) | 715 W (1,250 W surge) | yes | ~5.4 h |
| Window AC (12,000 BTU) | 1,100 W (1,800 W surge) | yes | ~3.5 h |
| Gas Furnace Blower (1/2 HP) | 800 W (2,350 W surge) | yes | ~6.8 h |
| Microwave (1000 W cooking) | 1,200 W | yes | ~2.3 h |
| Sump Pump (1/3 HP) | 800 W (1,500 W surge) | yes | ~17 h |
| Sump Pump (1/2 HP) | 1,050 W (2,150 W surge) | yes | ~13 h |
| Well Pump (1/2 HP) | 1,000 W (2,100 W surge) | yes | ~18 h |
Runtime uses each load's duty-weighted average draw against 90% of the rated capacity — conservative on purpose. Cyclic loads (fridges, pumps) run far longer than running-watts × capacity would suggest.

Common questions
What can the Jackery Explorer 3000 Pro run?
With 3,000 W of continuous output and a 6,000 W surge rating, the Jackery Explorer 3000 Pro runs refrigerator (modern), chest freezer, cpap machine (no humidifier), cpap with heated humidifier, oxygen concentrator, space heater (1500 w), and more. Its 3,024 Wh battery sets how long: a fridge for roughly a day, a CPAP for several nights.
How long will the Jackery Explorer 3000 Pro run a refrigerator?
A modern refrigerator averages about 53 W (it cycles ~35% of the time), so the Jackery Explorer 3000 Pro's 3,024 Wh runs one for roughly 52 h before recharging.
