Quick answer
EcoFlow and Bluetti both build long-life LiFePO4 power stations, but the price picture has flipped since this page first published. The EcoFlow Delta 2 now street-prices at $349-429 — below the Bluetti AC180’s $449-499 — while still recharging from a wall outlet in about 50 minutes, a third of the AC180’s time. The AC180 keeps one real edge: slightly more base capacity (1,152Wh vs. 1,024Wh) and a higher expansion ceiling (4,224Wh vs. 3,040Wh) for buyers planning to grow into a bigger system. It’s also currently listed as temporarily out of stock direct from Bluetti, with restock expected late November — worth checking before you plan around it.
EcoFlow and Bluetti sit right next to each other in the crowded 1kWh power-station class, and on paper their specs look close enough to make picking one feel like a coin flip. It isn’t — the two units trade off in opposite directions on the features that matter most day to day. Here’s the head-to-head, using their popular 1kWh units: the EcoFlow Delta 2 against the Bluetti AC180.
Head to head
| Spec | EcoFlow Delta 2 | Bluetti AC180 |
|---|---|---|
| Capacity | 1,024Wh LiFePO4 | 1,152Wh LiFePO4 |
| AC output | 1,800W (2,700W X-Boost) | 1,800W (2,700W lift) |
| Wall recharge to 80% | ~50 min | ~1.5 hr |
| Max solar input | ~500W | ~500W |
| Expandable | Yes, to 3,040Wh | Yes, to 4,224Wh |
| Weight | ~27 lb | ~35 lb |
| Price | $349-429 street (down from $699 list) | $449-499 direct (temporarily out of stock, restock late Nov) |
Last verified: September 28, 2026 — prices re-checked against this site’s own dedicated EcoFlow Delta 2 review (street pricing fell to $349-429 as of September 21, per Kotaku and 9to5toys deal-tracking coverage) and Bluetti AC180 review ($449-499 direct from Bluetti, currently listed as temporarily out of stock with restock expected late November). Both prices below were previously stale at this page’s original $699 and $499 figures.
Where EcoFlow wins
EcoFlow’s advantage is now speed and price together. According to EcoFlow’s published specs, the Delta 2 recharges from a wall outlet to 80% in about 50 minutes — roughly a third of the time the AC180 takes for the same top-up. That matters most during an actual outage, when a fast recharge between generator runs or grid-power windows can be the difference between staying powered and running dark overnight. Street pricing has also fallen to $349-429 as of late September 2026, per Kotaku and 9to5toys deal-tracking coverage — now below the AC180’s price rather than above it, reversing the value calculus this page originally described. The Delta 2 also expands to 3,040Wh with an add-on battery, though the AC180 actually expands further (4,224Wh, covered below). Both brands back their base units with a full 5-year warranty, so coverage length isn’t a differentiator here.
EcoFlow Delta 2
- ~50-minute wall recharge to 80% — the standout advantage over Bluetti.
- Expandable to 3,040Wh with an add-on battery if your needs grow.
- 2,700W via X-Boost handles resistive loads a straight 1,800W inverter would refuse.
Where Bluetti wins
Bluetti’s advantage is now capacity and expansion room, not price. The AC180 starts with slightly more base capacity than the Delta 2 — 1,152Wh versus 1,024Wh — and expands further too: up to 4,224Wh with Bluetti’s B80/B230/B300 add-on batteries, per bluettipower.com’s official specs, versus the Delta 2’s 3,040Wh ceiling. Bluetti rates the AC180’s LiFePO4 cells for 3,500+ cycles to 80% capacity, which works out to well over a decade of daily use before meaningful degradation. The catch as of late September 2026: Bluetti’s own site lists the AC180 as temporarily out of stock direct, with restock expected late November, and its $449-499 direct price no longer undercuts the Delta 2 the way it used to. If the bigger expansion ceiling matters more to you than price or immediate availability, the AC180 is still the pick.
Bluetti AC180
- More base capacity than the Delta 2, usually at a lower price.
- Rated for 3,500+ cycles to 80% capacity — well over a decade of regular use.
- Expandable to 4,224Wh with add-on batteries — the higher ceiling of the two.
The verdict
Buy EcoFlow (Delta 2) for the current best combination of price and speed — it’s now the cheaper of the two at $349-429 street, recharges roughly 3x faster, and it’s in stock, making it our overall best portable power station pick for a reason. Buy Bluetti (AC180) if the higher expansion ceiling (4,224Wh vs. 3,040Wh) or the slightly larger base capacity matters more to you than price, and you’re fine waiting out its temporary out-of-stock status direct from Bluetti. Both use long-life LiFePO4 and both are excellent 1kWh units; the price gap that used to favor Bluetti has closed in EcoFlow’s favor as of late September 2026. Also cross-shopping the value brands?
