BLUETTI AC2A vs EcoFlow RIVER 3

What separates these two

• CapacityThe BLUETTI states 205 Wh (nameplateNameplate capacity The capacity printed on the box, in watt-hours (Wh): what the battery holds when new. You get less out of it in use, because the station keeps some back to protect the battery and loses some turning it into 240 V or 12 V power.); the EcoFlow states 245 Wh (nameplate), 20% more.This means the EcoFlow holds more energy, so it can run the same things for longer before it needs charging.

  EcoFlow: manufacturer page (au.ecoflow.com) read 29 Sept 2026 245Wh

• Solar inputThe EcoFlow states 110 W; the BLUETTI states up to 200 W (at 12–28 V), 1.8 times as much.This means the BLUETTI can take in more solar power at once, so with enough panels in full sun it can charge back up faster.

Price and price per Wh aren't compared here yet. That needs a second shop selling each one for about the same price (within 10%), which shows the price is real. Today: price, BLUETTI $299 and EcoFlow $299; price per Wh, BLUETTI 146.0¢ and EcoFlow 122.0¢.

Can't be compared as the brands list themCan't be compared The two brands give this figure in different ways, or only one brand gives it. For example, one counts battery charges until 80% of the capacity is left and the other until 70%. Set side by side, the numbers would mislead, so both are shown and neither is put ahead.

• AC output, non-stopThe BLUETTI states 300 W (continuous or peak not statedContinuous or peak not stated The brand gives one output figure without saying whether it's the non-stop rating or a short burst, so it isn't compared with other stations' continuous figures.); the EcoFlow states 300 W (continuousContinuous output The power the station can supply non-stop. This is the figure that decides which appliances it can run, like a 1,000 W microwave.). One brand doesn't say if its figure is the non-stop power or a short burst.This means the two numbers were measured in different ways, so setting one against the other would mislead.

A difference is listed above only when both brands measure a figure the same way and the gap is at least: capacity: 10% or more; price: 10% or more; price per Wh: 10% or more; AC output, non-stop: 15% or more; weight: 8% or more; 12 V car socket: any difference; solar input: 20% or more; wall charging, empty to full: 20% or more; cycle life: 20% or more; stated warranty: any difference; UPS switchover: 5 ms or more; expansion batteries: one has it and the other doesn't; AC surge: 15% or more. Every comparison on this site uses the same gaps.

Fridge runtime for both

How long each would run an example fridge, a Dometic CFX5 45, with no solar and no driving. Its manufacturer says it uses 0.76 Ah an hour at 12 V when it is 32 °C outside and 4 °C inside. The brands don't publish some of the figures this needs. Where someone has tested the station, their result is used; otherwise both use the same ranges, taken from tests of other stations.

The middle estimates are 3 hours apart.This means the EcoFlow is likely to run the fridge for longer, but that one unknown figure could close the gap.

The biggest unknown is the station's own drawStation's own draw Power the station uses itself while an outlet is switched on: its screen, its electronics and the circuit that makes 12 V or 240 V. Few brands publish it. Over 24 hours it can add up to as much as a small fridge uses. with the 12 V socket12 V car socket A cigarette-lighter style socket that runs 12 V gear, like a camping fridge, directly. Its rating is in amps (A): a 10 A socket supplies up to about 120 W. on. No brand publishes it and no test of this station was found, so 1–12 W is assumed. On its own, it can change the EcoFlow's answer by up to 10 hours, which is more than the gap between the two.

Try another fridge, add solar or driving, or change the assumed ranges:

“Not stated” means the brand's website and manual don't give that figure (checked 29 Sept 2026).

All the specs side by side

Capacity is the nameplate figure in watt-hours (Wh), the one on the box. AC output is the power a station can supply non-stop, not a short burst. Weight is the station on its own. A figure measured another way is shown with a note saying how, and isn't compared with the others.

Where this pair sits

Price record

The BLUETTI AC2A's price has been recorded for less than two days, so there is no history to show yet.

What neither brand tells you

These figures would help answer the questions above, but neither brand gives them (checked 29 Sept 2026):
