How Long Does a 1800W Power Station Last?
1,024Wh to 1,433Wh · 1201-2000W output · $599 to $799
Quick answer
A 1800W power station (1,024-1,433Wh) typically lasts:
Range reflects smallest to largest battery in this class. Formula: (Wh x 0.85) / watts.
The 1800W class turns a power station into a kitchen backup system. With 1,024-1,433Wh batteries and 1,500-1,800W continuous output, these models run your refrigerator and microwave simultaneously, brew coffee, and still have headroom for lights and devices. This is the premium mid-range: enough power for a full day of home backup without the 60+ lb weight and $2,000+ cost of the high-capacity tiers.
Who is the 1800W class for?
Families who want to keep the kitchen running during a 12-24 hour outage (fridge + microwave + coffee), RV full-timers replacing shore power, small business owners powering equipment at farmers markets and events, and remote workers with high-draw setups (dual monitors + printer + router).

FAQ: 1800W Power Stations
3 questions specific to this wattage class
Can an 1800W station run a fridge and microwave at the same time?
Yes. A 150W fridge + 1,000W microwave = 1,150W total, well within the 1,800W limit. The microwave only runs for minutes at a time, so runtime impact is minimal compared to the fridge which cycles all day.
How long will an 1800W station power a house during an outage?
Running fridge (150W) + router (15W) + LED lights (40W) + phone charging (15W) = ~220W total. With a 1,433Wh battery: (1,433 x 0.85) / 220 = roughly 5.5 hours of continuous draw. With fridge cycling, real-world runtime reaches 12-16 hours.
Is 1800W enough for an RV?
For most RV needs, yes. It handles the microwave, charges devices, runs the TV, and powers LED lights. The limitation is air conditioning: a rooftop RV AC draws 1,200-1,500W running with a 3,000W+ surge, which exceeds this class.
