Spec deltas
Both carry the BLUETTI name, but they're built for different buyers. The AC180 (1,152Wh, 1,800W) and the EB3A (268Wh, 600W) come from different product lines with different engineering priorities and a $280 price gap. The AC180 has a slight edge, but the margin is close enough that your use case should break the tie.
What the spec gap means in practice: the AC180's 1,800W inverter has the headroom for a window AC, a full-size fridge, and power tools. The EB3A's 600W inverter can't run the heaviest of those — a window AC or a high-surge power tool needs more than it can hold, whatever its 1,200W surge ceiling does at the instant of startup. On stamina, the AC180 keeps a fridge alive for roughly 7 hours vs the EB3A's 2 hours. The cost? Portability. At 35.3 lbs, the AC180 is heavy enough to make you think twice about moving it. The EB3A at 10.1 lbs is something one person can actually carry.
Pick the AC180 if your primary use is cpap overnight or remote workday. Go with the EB3A if its specific strengths below line up better with your use. Keep scrolling for the full breakdown. The scenario verdicts below hold a few surprises.
Bench Notes
What each unit does well, where it falls short, and the trade-offs that matter.
BLUETTI AC180
The 1,800W inverter handles most daily devices like laptops, blenders, and TVs, but will struggle with heating elements that require over 1500W. A standout feature is the value proposition: at roughly $0.43 per watt-hour, it's one of the most cost-effective options on the market.
Strengths
- +Larger battery capacity
- +Higher AC output
- +Longer warranty
- +Faster solar charging
- +Rated for 3,500 charge cycles — much longer battery lifespan
Trade-offs
- –Significantly heavier (+25.2 lbs), making it harder to move.
BLUETTI EB3A
At 600W, this unit is strictly for personal electronics (phones, laptops) and small CPAP machines. Do not expect to run kitchen appliances. At only 10.1 lbs, it is exceptionally portable. You can easily carry it one-handed to a campsite or tailgating party.
Strengths
- +Lighter by 25.2 lb
Trade-offs
- –Weaker inverter (-1,200W) limits appliance compatibility.
- –Shorter-lived battery — rated for 2,500 charge cycles vs the AC180's 3,500, so it wears out sooner.

Either unit
This row is here for the EB3A's class of job: phones and a speaker, 100Wh across an afternoon. Both cover it — the EB3A finishes at 44% used, and the AC180 barely notices it. For this job the AC180's extra capacity is dead weight, not headroom; at 10.1 lbs the EB3A is the easier carry, but it is no longer sold, so the AC180 is the one to plan around.

Runtime model
Runtime = (rated capacity × 0.85 inverter efficiency) ÷ device wattage. Solar recharge estimates assume panels deliver 70% of rated output. Cold weather, battery age, and stacked loads reduce real-world results.
Power Score
Computed from 14 published spec dimensions, weighted per use-case bench. Higher is better; a unit must meet a bench's minimum threshold to be rated.
See the full weight table and data sourcing on our methodology page →Class ranking (the star rating)
Each unit's star score is a category ranking, not customer reviews — no buyer opinions feed it. We score every station on size-independent quality (value, output, portability, endurance, ports, warranty, and more), then percentile-rank it against the other units in its capacity class, so a class-leading compact unit and a class-leading whole-home unit can both earn 5★. Here, AC180 rates 4.4/5 (65th percentile of 27 Everyday-class units), and EB3A rates 3.9/5 (33rd percentile of 25 Personal-class units).
How the class ranking is computed →Test Notes & Caveats
Hidden gotchas and advantages we spotted that you won't find on the product page.
EB3A: 50dB Published
50dB is about as loud as moderate rainfall. The AC180 is rated 40dB — lower, but the two ratings need not describe the same operating regime even within one maker's own range, so the two figures are not a like-for-like gap. For most people, fan noise around 45dB and up is where sleep starts to suffer.
AC180: Power Lifting to 2,700W
The AC180 has BLUETTI's Power Lifting mode, which runs a resistive appliance rated up to 2,700W from its 1,800W inverter. It does that by delivering less power than the appliance asks for, not more than the inverter has: the heater still works, it just heats more slowly. Two things follow. BLUETTI scopes the mode to purely resistive loads — a heater, a kettle, an incandescent lamp — so it does nothing for a fridge compressor, a pump or a power tool; for motor loads the figure to read is the AC180's separate 2,700W surge peak, not this one. And it is not a reason to size down, because running a load that big from 1,152Wh is a short session either way. Genuinely useful if a heater or a kettle is why you're buying; beside the point otherwise. Our record for the EB3A carries no Power Lifting figure, only a 1,200W surge peak, which is a different rating, so check BLUETTI's own spec sheet before reading this as something the EB3A lacks.
Surge Power: Ratio and Ceiling Disagree
The EB3A holds the higher surge-to-continuous ratio (2× vs 1.5×), but the AC180 holds the higher absolute surge ceiling — 2,700W against 1,200W. These measure different things. The ratio says how much headroom an inverter keeps above its own rating; the ceiling says how big a startup spike it can actually swallow. A motor draws a number of watts at switch-on, not a multiple of someone else's rating, so on raw starting ability the AC180 is the stronger unit here — while the EB3A is the one running further below its own limit at steady state.
UPS Switchover: ≤20ms vs ≤30ms
Both list a UPS mode, at different rated speeds. The AC180 is rated ≤20ms — fine on paper for routers and most electronics; the fussiest PC power supplies sit right at this line. The EB3A is rated ≤30ms — a transfer this long is one many desktops will NOT ride through, so plan on reboots for sensitive gear. If a computer with unsaved work is the thing being protected, the stated class is worth the attention; nothing here is a lab result.
Warranty: 5 Years vs 2
The AC180 is covered for 5 years against the EB3A's 2 years. The AC180's figure is a maximum rather than a guarantee — it depends on buying direct from BLUETTI or registering the unit, since reseller purchases carry a shorter term. An underrated factor if you're keeping this unit for years.
Battery Lifespan in Real Years
The AC180 is rated for 3,500 cycles vs 2,500. In real life: at daily use, that's 9.6 vs 6.8 years. At weekend use (twice a week), it's 34 vs 24 years. One caution reading years across different sizes: a cycle is 1,152Wh on the AC180 and 268Wh on the EB3A, so count lifetime energy — roughly 4,032 kWh against 670 kWh over the rated life. After hitting the cycle limit, the battery doesn't die — it drops to ~80% of original capacity, which is still very usable.

Analyst note
The EB3A is no longer sold, so there is no price to work its cost per kWh from, and this comparison doesn't quote one. On what you can actually buy today, the AC180 works out at $0.12/kWh over its rated life. If you already own the EB3A, the hardware comparison still holds: over its rated life the AC180 delivers about 4,032 kWh and the EB3A about 670 kWh.
Growth path
AC180
FIXED CAPACITYFixed at 1,152Wh, with no expansion — so size it for your needs up front rather than planning to add capacity later.
Accepts up to 500W of solar. Suitable for a 1-2 panel setup.
Adequate ports for most setups, but heavy users may want a power strip.
EB3A
FIXED CAPACITYFixed at 268Wh, with no expansion — so size it for your needs up front rather than planning to add capacity later.
Accepts up to 200W of solar. Limited to a single portable panel.
Limited ports. You'll likely need a power strip or splitter.
Realistic full solar rechargeat 70% of rated panel output — see methodology
Analyst note
Growth only counts if you can still buy in, and the EB3A is no longer sold (BLUETTI points owners to the Elite 30 V2). That leaves the AC180: it is sealed at 1,152Wh, so buy the size that covers you now. The EB3A's fixed 268Wh still matters if you already own one, but it isn't a reason to pick it over the AC180.

The Bottom Line
The full picture comes down to this. The AC180 edges ahead on our overall analysis, but the margin is narrow enough that your specific use case should drive the decision. Review the scenario verdicts above — if the EB3A wins in the scenarios that match your life, it's the right choice regardless of aggregate scores.
If neither the AC180 nor the EB3A feels like the right fit, your power needs probably sit outside what these two target. If you're planning whole-home backup or running power-hungry appliances (electric heaters, window AC), you'll want a larger system in the 3,000–5,000Wh range with expansion battery support. Prices on portable power stations fluctuate frequently. Both BLUETTI discount regularly, so check the current price before committing. Prime Day and Black Friday pricing typically drops 20-30%.
Frequently Asked Questions
Answers drawn from the spec record and cited owner research.
How does the 884Wh capacity difference actually affect daily use?
The AC180's 1,152Wh battery keeps a mini-fridge running for roughly 7 hours vs the EB3A's 2 hours. What specs don't mention: runtime drops 20-30% in cold weather (below 32°F/0°C) as battery chemistry slows down. The AC180's extra capacity provides a critical cold-weather buffer. For occasional phone and laptop charging, both are overkill. This gap only matters for sustained, multi-appliance use.
Can I actually carry the AC180, or is the EB3A the only portable option?
The EB3A at 10.1 lbs is genuinely grab-and-go. Toss it in a backpack, carry it one-handed to a picnic, take it on a boat. The AC180 at 35.3 lbs is a different story. It's like carrying a large suitcase full of books. If you're setting up and breaking down camp frequently, this weight difference will exhaust you by day two.
How fast can each unit recharge from solar panels in real conditions?
On paper, the AC180 accepts 500W vs the EB3A's 200W of solar input. What the spec sheet won't tell you: solar panels typically deliver only 60-80% of their rated output due to panel angle, cloud cover, and temperature. In realistic conditions, expect full recharge in about 3.3 hours for the AC180 and 1.9 hours for the EB3A. That gap widens on cloudy days, when the AC180's higher input ceiling captures more of whatever sunlight is available. One more thing: summer gives you ~7 productive solar hours per day. Winter drops to ~4. If solar is your primary recharge method, the AC180's advantage is substantial.
"3,500 vs 2,500 cycles" — what does that actually mean for me?
In real years: the AC180 (3,500 cycles) lasts 9.6 years at daily use, 34 years at weekend use (twice a week), or 146 years at twice-monthly camping trips. The EB3A (2,500 cycles): 6.8 years daily, 24 years weekends, or 104 years twice-monthly. What most people miss: hitting the cycle limit doesn't kill your battery. Capacity drops to about 80%. Your 1,152Wh unit becomes a ~922Wh unit. Still very usable. For weekend users, both batteries will outlast the warranty by years.
Bottom line: should I buy the AC180 or the EB3A?
We'd buy the AC180. The EB3A is no longer sold, so there is no price to weigh it against; the comparison on this page still helps if you own one.
