Brand showdown · three classes · official specs only

Jackery vs EcoFlow vs Bluetti

Brand loyalty pages are usually adjectives in a trench coat. This one is a table: three models per brand, one in each capacity class, every number from the manufacturer's own spec sheet, and a published scoring formula doing the verdicts. No prices, no hands-on claims, no sponsored order.

Affiliate disclosure: this guide contains links to Amazon. As an Amazon Associate we earn from qualifying purchases made through those links — at no extra cost to you. Commissions never enter our scoring formula, and no brand can pay for placement here.

Ground rules

How to read this page

Each brand faces off in three capacity classes — ultralight (under 300 Wh), the 1 kWh class (900–1,200 Wh), and 2 kWh-and-up — using the models we currently track. In each showdown table, the best value in every row is highlighted; a row can have more than one winner when specs tie.

One row is derived rather than printed on the box: Energy density (Wh per lb = capacity ÷ weight). It repackages two scored inputs into a handy portability ratio — it informs the tables but does not change the 0–10 formula.

The 0–10 scores are our site-wide scores, normalized across all tracked power stations — so a 7.8 here means exactly what it means on every other page. We also track three Anker models; they're excluded from these brand tables only because the question was these three brands. Their numbers live on the full comparison page. The formula and its weights are published on How We Score.

The scoreboard, by brand

Averages over each brand's tracked models; row wins count every highlighted cell across the three showdown tables.

Averages describe the three models we track per brand, not the brand's whole catalog. Lineups change; the date stamp in the footer shows when these specs were last verified.

Honesty box

What a spec sheet can't tell you

This page compares numbers, and numbers are not the whole purchase. Warranty terms, app quality, expansion-battery ecosystems, fan noise, and customer support all differ between these brands — and none of them appear in a spec table, so we don't score them. Check the warranty and return terms on the brand's own site before you buy; the official source page for every figure here is linked from each product sheet.

If you're sizing for a job rather than a brand, the power-outage guide and the CPAP camping guide turn these same specs into hours of runtime and nights of sleep. Verify current pricing on Amazon — we never display prices we cannot verify live.
