Jackery Explorer 1000 Pro: Runtime & Specs

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

The Jackery Explorer 1000 Pro 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

The Explorer 1000 Pro kept the original Explorer 1000's battery size (1,002 Wh, NMC) and its 1,000 W output, and fixed its charging. Solar input rises from 126 W to 800 W through two inputs, and the wall charger fills it in about 1.8 hours instead of about 7.

The output is what didn't change. 1,000 W runs a full-size fridge (about 15 hours) and a drip coffee maker, but not a microwave or a 1/2 HP sump pump. Jackery's spec sheet rates the cells for 1,000 cycles to 80%, though another Jackery FAQ says about 500, so treat cycle life as the soft spot of this model.

If you want a step up, the current Explorer 1000 Plus has a bigger LiFePO4 battery (1,264 Wh), twice the output (2,000 W), a 20 ms UPS mode and can be expanded, at the cost of 6.6 extra pounds (32 lb against 25.4).

Simulated runtimes (not measured)

Nobody tested this unit for this page. These figures come from a computer simulation of the Explorer 1000 Pro, 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 Pro
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	20 hours	19 hours to 23 hours	16 hours
Starlink Standard	9.5 hours	8.6 hours	8.2 hours to 9.1 hours	7 hours
Refrigerator (full-size, ENERGY STAR)	15 hours	12 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 Pro 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 Pro 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 Pro?

The Jackery Explorer 1000 Pro 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 Pro take to charge?

Jackery's published charging claim: “0–100% in 1.8 hr (AC)”. Max AC charging power is 800 W. With solar, it accepts up to 800 W (400 W per input). With 800 W of panels that's roughly 1.7 hours of good sun from empty.

Is the Jackery Explorer 1000 Pro expandable?

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