BLUETTI and EcoFlow both cover everything from a small camping unit to whole-home systems. Rather than crown a brand on vibes, we compare their most-bought home backup models, spec by spec, based on manufacturer specs and public reviews.
EcoFlow if you want the shortest UPS switchover and the fastest wall recharge, or a clear path to a 240V whole-home setup with the DELTA Pro 3. BLUETTI if you want a longer listed warranty and a strong 1 kWh value pick with Power Lifting for resistive loads.
The 1 kWh duel: AC180 vs DELTA 3 Plus
| Model | Capacity | Output | Solar in | Voltage | UPS |
|---|---|---|---|---|---|
| BLUETTI AC180 | 1,152 Wh | 1,800 W | 500 W | 120V | 20 ms |
| EcoFlow DELTA 3 Plus | 1,024 Wh | 1,800 W | 500 W | 120V | < 10 ms |
"check" = not confirmed on the sources we used; verify on the manufacturer page before buying.
| Spec | BLUETTI AC180 | EcoFlow DELTA 3 Plus |
|---|---|---|
| Surge / boost | 2,700 W surge, Power Lifting 2,700 W | 3,600 W surge, X-Boost 2,200 W |
| Wall charging | 1,440 W, 1.3–1.8 h | 1,500 W, about 56 min |
| Weight | 35.27 lb | 27.6 lb |
| Cycle life | 3,500+ to 80% | 4,000 to 80% |
| Warranty | 5 years (BLUETTI) | check EcoFlow |
The DELTA 3 Plus is lighter, charges faster and lists a sub-10 ms UPS, which makes it the better desk-side backup. The AC180 offers slightly more capacity (1,152 vs 1,024 Wh) and BLUETTI's listed 5-year warranty.
Home backup flagships
EcoFlow's DELTA Pro 3 (4,096 Wh, 4,000 W, 120/240V) is the clearer home-backup flagship in the US today, with its Smart Home Panel 2 for integration. BLUETTI also sells large expandable systems; because model names and specs vary by region, compare the current line-up on BLUETTI's site against the DELTA Pro 3 figures in our whole-house guide.
Ecosystem and support
- Panels: both sell folding panels; BLUETTI's PV200 and EcoFlow's 220W bifacial are the common pairings. See best 200W panels.
- Expansion: both offer expansion batteries on many models; check compatibility per model.

Portable power stations are designed to be used plug-in, like an appliance. Anything wired into your home (inlet box, transfer switch, sub-panel, batteries feeding a circuit) must be installed by a qualified, licensed electrician and comply with local code. Never backfeed a house through an ordinary outlet.
FAQ
Is BLUETTI or EcoFlow more reliable?
We have not run long-term reliability tests, and neither brand publishes failure-rate data. Both sell LFP-based stations with thousands of rated cycles. Compare warranty length and local support availability, which are verifiable.
Which charges faster from the wall?
In the 1 kWh class, the DELTA 3 Plus lists 1,500 W AC input and about 56 minutes to full; the AC180 lists up to 1,440 W and 1.3 to 1.8 hours. Both are fast enough to refill during a brief grid return.
Which has the better app?
Both offer app control. App experience is subjective and changes with updates; read recent public reviews for the current state.
Can I use BLUETTI panels with an EcoFlow station?
Often yes with the right adapter, as long as the panel voltage and current are within the station's solar input limits. Check connectors (MC4 vs XT60 vs proprietary) and the voltage window first.
