How long will the Jackery Explorer 2000 v2 run a refrigerator?

About 41.9 h for a median ENERGY STAR top-freezer fridge (363 kWh a year, 41.4 W average), 26.9 h for a bottom-freezer (566 kWh) and 23.7 h for a side-by-side (640 kWh). That uses 1,735.7 Wh of usable energy: 2,042 Wh × 100% usable × 85% efficiency. Its output covers a modern fridge's compressor (160 W running, 320 W start-up) and defrost heater (425 W).

How many nights will the Jackery Explorer 2000 v2 run a CPAP?

About 19.4 eight-hour nights for a ResMed AirSense 10 at 10 cmH2O with no humidifier (11.2 W, from ResMed's battery table), or 7.9 with the humidifier at 4 (27.6 W). Ask your equipment supplier before relying on a power station for a medical device.

How long does the Jackery Explorer 2000 v2 take to charge?

Jackery lists 1.8 h from a wall outlet, 1.3 h in Emergency Charge (app), and 24 h from a car's 12 V socket. Its solar input takes up to 400 W.

Runtime for common appliances

Hours = 2,042 Wh × 100% usable × 85% efficiency ÷ (the appliance's watts), one appliance at a time, from full. Basis: Jackery's published 0.85 runtime factor; 100% of capacity usable (the station's own cutoff), an example since the maker doesn't publish it. The output check compares the station's 2,200 W output with the appliance's peak running draw (a fridge's defrost heater counts) and its 4,400 W surge with the start-up draw.

CPAP nights

Medical equipment

A power station is not a medical backup system, and these are planning estimates. Ask your device maker or equipment supplier how to run your CPAP from battery power, and keep a plan for longer outages. What to check first.

Eight-hour nights at 10 cmH2O, through the AC outlet
AirSense setup	Draw, W	Nights
No humidifier, SlimLine tubing	11.2	19.4
Humidifier at 4, SlimLine tubing	27.6	7.9
Humidifier at 8, SlimLine tubing	43.9	4.9
Heated tube (ClimateLineAir at 30°C), no humidifier	18.2	11.9

AirSense 11, typical (ResMed user guide)	56.1	3.9

AirSense 10 draw is ResMed's battery-guide figure in amps at 12 V DC × 12 (ResMed battery guide). Nights = usable energy ÷ (draw) ÷ 8 hours. Other pressures and machines: CPAP calculator.

Sump pumps

Start-up allows 3 × running watts, the top of Whirlpool's two-to-three-times range for motors. The example storm pace is 6 cycles an hour of 15 seconds each; time your own pump during rain.

Running watts are each pump's rated amps × volts, so they err high. Sump pump calculator.

Charge time and solar refill

Empty to full, from Jackery's published figures
Method	Time	Maker's figure
Wall outlet, standard	1.8 h	AC charging time 1.75 hours; Emergency Charge 1.3 hours. AC input listed as 15 A max, no watts
Wall outlet, fastest mode	1.3 h	Emergency Charge (app)
Car's 12 V socket	24 h	DC input 11–16 V ⎓ 8 A; 12 V car adapter charging time 24 hours

"est." = worked out from input watts × 0.74 (wall) or 0.89 (car), the medians makers' own watts-and-time figures imply. See Methods.

Days of sun to fill from empty with 400 W of panels (its solar limit)
