Both excel: Delta 2 is faster and expandable; AC180 is steadier and quieter.
A few summer storms knocked out my power twice in one week. That pushed me to test the Ecoflow Delta 2 vs Bluetti AC180 side by side—at home, in my van, and on a weekend camp. Both kept my fridge cold and my laptop humming. But they solve the same problem in slightly different ways: one charges insanely fast and expands, the other runs quieter with a smoother UPS handoff. I’ve lived with both. Here’s what I learned so you can pick the right fit.
Is Ecoflow Delta 2 Good?
Yes—especially if you want speed, flexibility, and room to grow. The Ecoflow Delta 2 hits hard with blazing wall charging, lots of high-powered USB-C, and the option to add extra batteries later. If you bounce between home backup, road trips, and power-hungry hobbies, it checks many boxes in one compact unit.
On a cabin weekend, I brewed coffee, ran a projector, and topped off e-bikes. The Delta 2 jumped from near empty to almost full over lunch on wall power. During a storm, I paired it with an extra battery and stretched my fridge run-time by another day. That expandability saved my groceries and my nerves.
EF ECOFLOW Portable Power Station DELTA 2, 1024Wh LiFePO4 (LFP) Battery, 1800W AC/100W USB-C Output, Solar Generator(Solar Panel Optional) for Home Backup Power, Camping & RVs
What Makes It Stand Out / Key Features
- 1024Wh LiFePO4 battery with long cycle life (thousands of cycles)
- 1800W AC output (surge up to ~2700W; X-Boost for resistive loads)
- Ultra-fast AC charging (about 0–80% in ~50 minutes)
- Expandable capacity up to 2048Wh or ~3040Wh with add-on batteries
- Rich ports: multiple AC outlets, two 100W USB-C, four USB-A, 12V car port
What I Like
- Lightning-fast wall charging saves time between uses
- Two 100W USB-C ports power laptops without bricks
- Expandability means you can “grow” your system later
- Polished app with Wi‑Fi/Bluetooth and charge rate controls
- Six AC outlets (US model) reduce the need for a power strip
What Could Be Better
- Fans can get loud during fast charging or heavy loads
- Heavier than it looks when you add extra batteries
- UPS transfer is fine for most gear, but not the fastest
My Recommendation
If you want speed, ports, and future-proof capacity, the Delta 2 is a smart buy. It’s often discounted and broadly available.
| Best For | Why |
|---|---|
| Mixed home backup + travel | Fast charge, many ports, compact shape |
| Power users and creators | Dual 100W USB‑C and strong AC output |
| Growing into larger setups | Expandable battery options |
Is Bluetti AC180 Good?
Yes—and it might be better if you value quiet operation and a smoother UPS. The Bluetti AC180 offers a larger 1152Wh LFP battery in a tough body, fast AC charging, and a calm fan profile. If you want a steady home backup for routers, CPAPs, or a small fridge, it performs well.
In my van, the AC180 ran a 12V fridge, lights, and my laptop all weekend. At home, I used its UPS mode to keep my internet up during a surprise outage. The switchover was quick and clean—streaming never dropped. It felt like an invisible safety net.

What Makes It Stand Out / Key Features
- 1152Wh LiFePO4 battery for a bit more base capacity
- 1800W AC output with “power lifting” for resistive loads
- Very fast AC charging (about 0–80% in ~45 minutes)
- Reliable UPS functionality with fast transfer time
- Solid build, clean display, and app control
What I Like
- Quieter fan behavior under light and medium loads
- Excellent UPS performance for home office gear
- Good efficiency and steady voltage under load
- Simple layout with four AC outlets (US model)
- Strong LFP cycle life and a long warranty
What Could Be Better
- No battery expansion—what you buy is what you have
- Heavier than the Delta 2, not as easy to carry
- Fewer high-watt USB‑C ports than Ecoflow
My Recommendation
If you want a calm, steady backup with great UPS behavior, choose the AC180. It’s a dependable, quiet worker.
| Best For | Why |
|---|---|
| Home office UPS | Quick switchover keeps routers and PCs online |
| Vanlife and quiet spaces | Lower fan noise at modest loads |
| Simple, set‑and‑forget backup | Solid capacity with minimal fuss |
