What size power station do you need for a job site?

Job-site use inverts the camping calculus: the average draw is modest (chargers and lights), but the peaks are brutal — a corded circular saw or compressor pulls 1,400W+ running and far more at start-up. The table therefore only lists stations rated 1,800W continuous or more; below that, corded tools trip the inverter no matter how big the battery is.

The two columns bracket a day: keeping cordless-tool batteries topped up with the occasional corded cut (~150W average), and leaning on corded tools regularly (~400W average). If your day is mostly corded tools, look at the 2kWh+ class and expansion-capable stations — see the expansion battery register.

How the table is computed: runtime = rated capacity × 85% usable ÷ average draw. Prices are today's price at each brand's official store (including on-page promo prices where we can verify them); the table re-ranks every night. Omitted: out-of-stock models, models without a current battery-only price, models whose runtime rounds below half a hour, and stations below 1,800W continuous output (or without a published rating) — they can't run this load regardless of capacity.
