This index prices the 2 kWh-class power stations we track the way a household actually spends them: per watt-hour of stored energy. Every listing in this class leads with capacity and output watts, and the stations sit within a few dollars of each other on the shelf — but a watt-hour is not priced the same everywhere. The figures below are the dataset behind our comparison of solar generators for home backup, published here in citable form for readers, writers, and researchers. Prices verified October 28, 2026. Refreshed quarterly.
Finding 1: two stations cost the same $899 — and hold different amounts of energy
The Bluetti Elite 200 V2 and the Jackery Explorer 2000 v2 both sell for $899. They do not hold the same charge: the Bluetti is rated at 2,074 watt-hours, the Jackery at 2,042. Divide the identical sticker by the rated capacity and the Bluetti’s watt-hour costs 43 cents against the Jackery’s 44 — a small gap, but it runs in the opposite direction from the shelf, where the two look interchangeable. At the same price, capacity is the whole difference.
Finding 2: the EcoFlow’s watt-hour costs about 16% more
The EcoFlow DELTA 2 Max holds 2,048 watt-hours — squarely between the other two, in a class where every station sits within 1.6% of the same capacity — and sells for $1,029. That works out to 50 cents per watt-hour, about 16% more than the Bluetti’s 43 cents, for essentially the same stored energy. What the extra $130 buys is real, and our comparison scores it: the fastest recharge of the three priced stations, and an expansion-battery path neither of the other two offers. It does not buy more energy.
Finding 3: no listing prints this number — and one station in the class can’t be priced at all
Cost per watt-hour appears nowhere in these listings; a buyer has to do the division themselves. And one of the four stations in our comparison, the Bluetti AC200L (2,048 watt-hours), had no Amazon price we could verify on the check date, so it carries no figure here at all. Any cost-per-watt-hour ranking that includes it is built on an estimate. We list what a buyer could actually pay on the check date, and never estimate a price for a station that isn’t selling at one.
The dataset — prices verified October 28, 2026
| Station | Capacity | Amazon price | Cost per Wh |
|---|---|---|---|
| Bluetti Elite 200 V2 | 2,074 Wh | $899 | $0.43 |
| Jackery Explorer 2000 v2 | 2,042 Wh | $899 | $0.44 |
| EcoFlow DELTA 2 Max | 2,048 Wh | $1,029 | $0.50 |
| Bluetti AC200L | 2,048 Wh | Not priced | — |
How to read this table: cost per watt-hour is the verified Amazon price divided by the manufacturer’s rated capacity. It can only be computed where a station has a verified price — that’s why the AC200L, with no verifiable Amazon price on the check date, is listed unpriced rather than estimated.

Methodology
Prices were verified on October 28, 2026 against the Amazon listings for these stations and cross-checked against independent price-tracking records of the same listings. Capacities are each maker’s own published ratings. Cost per watt-hour uses rated capacity, not delivered capacity — inverter losses mean a station delivers roughly 85% of its rating to your appliances, the same honest factor our comparison and our home power sizer use for runtimes; applied evenly, it would raise every figure here by the same proportion and change no ranking. Ordinary Prepper is a research desk: we work from published specs, verified prices, and aggregated owner feedback — we don’t bench-test, and no figure here comes from a sample or a sponsor. Ordinary Prepper earns affiliate commissions on some products it writes about; no commission changes a figure in this index.
