A 2,000 W inverter in a portable body, and it scales to 5 kWh with add-on batteries. Here's exactly what it runs, how long, and which outages it covers — computed, not marketed.
~1.7 h AC; expandable to 5 kWh · 32 lb · 3× AC, USB-A/C, car · expandable with add-on batteries.
What the Explorer 1000 Plus runs — and for how long
| Appliance | Running | Runs it? | Approx. runtime |
|---|---|---|---|
| Refrigerator (modern) | 150 W (1,200 W surge) | yes | ~22 h |
| Chest Freezer | 100 W (1,000 W surge) | yes | ~33 h |
| CPAP Machine (no humidifier) | 40 W | yes | ~28 h |
| CPAP with Heated Humidifier | 60 W (95 W surge) | yes | ~24 h |
| Oxygen Concentrator | 350 W (600 W surge) | yes | ~3.3 h |

| Window AC (8,000 BTU) | 715 W (1,250 W surge) | yes | ~2.3 h |
| Window AC (12,000 BTU) | 1,100 W (1,800 W surge) | yes | ~1.5 h |
| Gas Furnace Blower (1/2 HP) | 800 W (2,350 W surge) | yes | ~2.8 h |
| Microwave (1000 W cooking) | 1,200 W | yes | ~0.9 h |
| Sump Pump (1/3 HP) | 800 W (1,500 W surge) | yes | ~7.1 h |
| Sump Pump (1/2 HP) | 1,050 W (2,150 W surge) | yes | ~5.4 h |
| Well Pump (1/2 HP) | 1,000 W (2,100 W surge) | yes | ~7.6 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 1000 Plus run?
With 2,000 W of continuous output and a 4,000 W surge rating, the Jackery Explorer 1000 Plus runs refrigerator (modern), chest freezer, cpap machine (no humidifier), cpap with heated humidifier, oxygen concentrator, space heater (1500 w), and more. Its 1,264 Wh battery sets how long: a fridge for roughly a day, a CPAP for several nights.
How long will the Jackery Explorer 1000 Plus run a refrigerator?
A modern refrigerator averages about 53 W (it cycles ~35% of the time), so the Jackery Explorer 1000 Plus's 1,264 Wh runs one for roughly 22 h before recharging.
