Best mid-size power stations (500–1,024Wh), ranked by current price and verified specs

The 500–1,024Wh class covers a weekend of camping or a day of essential-load backup — the most-shopped size in the market and the most campaign-priced one. Ranked by the spec-value score: price per watt-hour plus verified capability.

Prices are today's price at each brand's official store, including on-page promo prices where we can verify them (see methodology). The rated cycle-cost estimate = price ÷ (capacity × manufacturer-rated cycles). Methodology.

The spec-value score compares current price with verified published capabilities. It does not measure build quality, reliability, noise, software quality, or customer support.

How the spec-value score works (0–100, same rubric on every page): up to 60 points for price efficiency — $0.30/Wh or better scores the full 60, $1.00/Wh or worse scores 0, linear in between — plus up to 40 for verified capability: solar charging 0/4/8/12 (none · ≤200W · ≤600W · >600W), inverter strength 0/5/10 (continuous watts per Wh of capacity: under 0.4 · under 0.9 · 0.9+; DC-only units 0), ports up to 12 (2+ AC outlets 4 — a rated AC inverter earns this base credit when the outlet count is unverified — 4+ outlets 6 · USB-C 3, +1 at 100W+ · 12V output 2), UPS 4, expandable 2. A "—" means the manufacturer doesn't state it or we haven't verified it — it scores zero rather than being guessed, so a missing spec is visible, never hidden.
