Quick answer
The Bluetti AC180 is the cheapest way into a real 1kWh-class power station in 2026 — a 1,152Wh LiFePO4 battery, 1,800W continuous AC output (2,700W surge), and a price that’s actually dropped to $449-499 direct from Bluetti, down from the roughly $599 street price we tracked earlier this year. It backs that up with a 5-year warranty and a genuine expansion path (up to 4,224Wh with add-on batteries), both of which beat what its price tag would suggest. The trade-off, beyond the heavier build and slower recharge covered below: as of September 2026, Bluetti’s own site lists the AC180 as temporarily out of stock, with restock expected in late November — it hasn’t been discontinued, but it’s worth checking current availability before you plan around it.
We’ve referenced the AC180 across several brand-vs-brand comparisons on this site as the value pick. This review pulls those threads into one place — including a correction to a spec we’d previously gotten wrong.

What we like
- Lowest price in its class, and it just got cheaper. At $449-499 direct from Bluetti — down from the roughly $599 we tracked earlier this year — the AC180 undercuts the EcoFlow Delta 2 and Anker SOLIX C1000 (both ~$699) by $150-250 while matching their 1,800W continuous rating and offering slightly more base capacity (1,152Wh vs. 1,024-1,056Wh).
- A real expansion path, not a dead end. Bluetti’s official AC180 specs confirm compatibility with the B80, B230, or B300 add-on battery, growing total capacity to as much as 4,224Wh — useful for buyers who want to start small and scale up later without replacing the base unit.
- Warranty punches above its price. Five years of coverage matches the pricier EcoFlow Delta 2 and Anker SOLIX C1000, and beats the Jackery Explorer 1000 v2’s 3-year term outright.
- Strong cycle life. 3,500+ cycles to 80% capacity is competitive with every other 1kWh-class unit on this site, so a daily-cycled AC180 should still hold most of its capacity after roughly a decade of regular use.
Where it falls short
- Slowest wall recharge of the four core brands. About 1.5 hours to full trails the EcoFlow Delta 2’s roughly 50-minute time and the Anker SOLIX C1000’s roughly 58-minute time by a wide margin — a real downside if you’re topping up quickly between trips or during a multi-day outage.
- Heaviest 1kWh-class unit we track. At roughly 35 lb, it’s about 11 lb heavier than the Jackery Explorer 1000 v2 and around 9 lb heavier than the EcoFlow Delta 2 or Anker SOLIX C1000 — noticeably more to carry in and out of a vehicle.
- Expansion batteries are a separate purchase. The B80/B230/B300 add-on batteries aren’t included and add meaningfully to the total cost, so the $449-499 entry price doesn’t include the capacity ceiling that makes the AC180 attractive on paper.
- Temporarily out of stock direct from Bluetti. As of September 2026, Bluetti’s own site lists a late-November restock date for the AC180 — third-party retailers may still have units, but check current availability before counting on it.
Who should buy it
The AC180 is the right call if budget is the top priority and you can live with a slower recharge and extra weight — it’s our value pick among 1kWh-class stations. If recharge speed matters more than price, the EcoFlow Delta 2 tops up in about a third of the time. If you want the lightest possible unit, the Jackery Explorer 1000 v2 is about 11 lb lighter, though its warranty is two years shorter. And if app polish and the fastest true 0-100% charge matter most, the Anker SOLIX C1000 is the more refined choice at a similar price to the EcoFlow. If 1,800W of continuous output is more than you need, Bluetti’s own AC70 drops to 768Wh and a 1,000W inverter for roughly $200 less. If you’ve spotted a Renogy Phoenix 1000 on a deep discount, it can match the AC180 on price — but the AC180’s 5-year warranty and 3,500+ cycle life beat Renogy’s 1-year/2,000-cycle terms by a wide margin. If you need more capacity and want the best cycle-life rating Bluetti currently sells, step up to the Elite 200 V2, rated for 6,000+ cycles at 2,073.6Wh.
Bluetti AC180 (1,152Wh)
- Lowest price of any 1kWh-class station we track, typically about $100 under EcoFlow and Anker.
- 5-year warranty and 3,500+-cycle LiFePO4 pack — durability that outpaces its price point.
- Genuine expansion path to 4,224Wh with Bluetti's B80/B230/B300 add-on batteries (sold separately).
If you do add a B80 or B230 battery down the line, it ships in an awkward, heavy box — Amazon Prime gets solar panels, spare batteries, and cables to your door free in two days, and you can try it free for 30 days.
The bottom line
The Bluetti AC180 is the best value in the 1kWh-class power station field in 2026 — cheaper than ever at $449-499, well warrantied, and genuinely expandable, despite what we’d previously written about it on this site. It’s slower to recharge and heavier than its rivals, and temporarily out of stock direct from Bluetti until late November, but for buyers who care more about price and cycle life than speed or weight, it’s a hard station to beat once it’s back.
