Jackery Explorer 1000: Runtime & Specs

By Hicham M. · Specs from Jackery's published documents, as of September 2026 · How we calculate

The Jackery Explorer 1000 is a 1,002 Wh NMC lithium-ion power station with 1,000 W of continuous AC output and a 2,000 W surge rating. It runs a typical full-size fridge for about 15 hours. It has been replaced or discontinued, but many are still in use.

Our notes

Lots of original Explorer 1000s are still around, and the specs show their age. It uses NMC cells rated for 500 cycles, where Jackery's current Explorer 1000 v2 uses LiFePO4 rated for 4,000. If you're buying one used, how many times it has been cycled matters much more than with an LFP model.

Charging is the other weak point. The wall adapter takes about 7 hours, solar input tops out at 126 W, and the USB-C ports give only 18 W, too little for most laptops. The Explorer 1000 v2 charges from the wall in about 1.6 hours and takes 400 W of solar.

It still does real work in an outage: a full-size fridge for about 15 hours, a CPAP for about 28. Its 1,000 W output can't run a microwave or a 1/2 HP sump pump. If you already have one, keep it for the odd outage. If you're shopping for a solar setup you'll cycle daily, buy something newer.

Simulated runtimes (not measured)

Nobody tested this unit for this page. These figures come from a computer simulation of the Explorer 1000, and they are estimates. The plain runtime table below divides energy by average draw at 85% efficiency. The simulation also charges the battery for the power the inverter burns just by being switched on, which is why small loads come out shorter. Where we have measured a unit, the measurement is shown separately and labeled as measured.

Simulated runtimes for the Jackery Explorer 1000
Device	Spec-sheet math	Simulated, typical	Likely range	Simulated at 0 °C
Wi-Fi router + modem	2.4 days	31 hours	27 hours to 37 hours	25 hours
CPAP (no humidifier)	28 hours	21 hours	19 hours to 23 hours	17 hours
Starlink Standard	9.5 hours	8.7 hours	8.2 hours to 9.1 hours	7 hours
Refrigerator (full-size, ENERGY STAR)	15 hours	13 hours	12 hours to 13 hours	10 hours

Nonstop runtime from full to battery cutoff. Likely range = middle 80% of 200 simulated runs with the uncertain inputs varied. The inverter idle draw is assumed, not published: we assumed about 14 W for this model, varied from 8 to 21 W. If the real figure is lower, real runtimes land closer to the spec-sheet column.

How this was simulated

The battery is stepped down every 2 minutes until it reaches cutoff, for 200 runs per device. Results are seeded, so the page shows the same numbers on every build.
Battery draw = load + inverter idle draw + 4–8% of the load + a loss that rises with load squared (4% at full output).
Usable capacity = 92–98% of rated Wh, for protection cutoff and aging.
At 0 °C, 75–88% of that capacity is assumed available.
Fridges cycle on and off every 30–50 minutes at the share of the time set by their average draw. The inverter idle draw continues while the compressor is off.
Devices that exceed this model's output or surge rating are left out. Loads are US 120 V devices.

Questions

How long will the Jackery Explorer 1000 run a refrigerator?

About 15 hours for a typical ENERGY STAR full-size fridge averaging 58 W, assuming 85% inverter efficiency. Older or larger fridges use more. Try your own numbers.

Can the Jackery Explorer 1000 run a microwave?

Not a full-size one. A typical 1,000 W microwave pulls about 1,500 W from the outlet, more than its 1,000 W continuous output.

How many amp-hours is the Jackery Explorer 1000?

The Jackery Explorer 1000 works out to about 83.5 Ah at 12 V, or 78.3 Ah at 12.8 V, the nominal voltage of a 12 V LiFePO4 battery. Both are our conversion of Jackery's 1,002 Wh rating: amp-hours = watt-hours ÷ volts. The battery inside may run at a different voltage, so an amp-hour figure in a manual or on a product listing can look very different for the same energy. For scale, a 12 V 100 Ah LiFePO4 battery holds 1,280 Wh, so this model holds about 78% as much as one. How we convert amp-hours.

How long does the Jackery Explorer 1000 take to charge?

Jackery's published charging claim: “~7 hr (AC adapter)”. Max AC charging power is 180 W. With solar, it accepts up to 126 W. With 126 W of panels that's roughly 11 hours of good sun from empty.

Is the Jackery Explorer 1000 expandable?

No. Its capacity is fixed at 1,002 Wh.
