EcoFlow RIVER 3 Plus vs Bluetti EB3A

On paper these two are nearly the same station. Same inverter rating, same car port limit, same battery chemistry. The EcoFlow RIVER 3 Plus holds a little more and takes a little more solar, so it comes out slightly ahead in every runtime table below. The difference that might actually decide it is a line on the spec sheet we only have for one of them: Bluetti publishes a surge rating for the Bluetti EB3A, and EcoFlow doesn’t publish one for the RIVER 3 Plus.

Specs side by side

A word on the surge row. EcoFlow’s manual gives no surge figure for the RIVER 3 Plus. It does mention X-Boost, but X-Boost isn’t a surge rating, so we don’t treat it as one. When our tables check a startup draw against the RIVER 3 Plus, they use its continuous rating as the limit. That’s us being cautious, not a number from EcoFlow, and the station may well handle short spikes above it. We just can’t tell from the manual.

On this page that caution never changes a result, because none of the appliances below come with a startup figure. It matters when you plug in something with a motor or compressor that kicks hard when it starts. For that, the EB3A at least gives you a published number to check against. Our guide to surge watts explains why the startup draw can be the thing that trips a small inverter.

CPAP

On 12V with ResMed’s DC adapter, the ResMed AirSense 11 gets 4.5 hours from the RIVER 3 Plus and 4.5 hours from the EB3A. That’s ResMed’s typical figure, not a worst case, and it’s still short of a full night for a lot of people. These are small stations, and a full-size CPAP shows it.

The ResMed AirMini is a different story. It draws so little that either station runs it for 41.0 hours (RIVER 3 Plus) or 38.5 hours (EB3A) on 12V. If you travel with an AirMini, a station this size makes sense. If you use a bedside machine, look at our CPAP runtime table for the bigger stations.

Starlink Mini and a laptop

Starlink gives a range for the Mini’s average draw, and we use the top of it. If your Mini draws less than that, you get more hours than this. The 12V rows assume you have Starlink’s DC cable for the car port. Our Starlink page goes into that.

Laptops are harder to pin down, because the makers only publish the charger rating, which is the most the laptop can pull, not what it usually draws. Taking those ratings at face value, the Apple MacBook Air 13-inch (M4, 2025) gets 8.0 hours on the RIVER 3 Plus and 7.5 hours on the EB3A. The Apple MacBook Pro 16-inch (2024, M4 Pro/Max) gets 1.7 hours and 1.6 hours. Treat both as floors. A laptop doing ordinary work will usually go a lot longer than that. More on why in our laptop runtime page.

A small 12V fridge

Dometic’s daily figure for the Dometic CFX3 25 is for a hot day, so a cooler one should stretch it. Even so, on either station you’re looking at roughly a day of cooling with no charging. That’s fine for an overnight trip. For anything longer you’d want solar or a charge while you drive, which brings us to the one place the RIVER 3 Plus pulls a little further ahead.

Solar

The RIVER 3 Plus takes a bit more solar than the EB3A. With one small folding panel that probably makes no difference, because the panel limits you before either station does. The gap only shows if you bring enough panel to go past the EB3A’s limit. Our solar recharge calculator will tell you whether your panel does.

What neither one runs

A small inverter rules out the big heating loads. The Hamilton Beach Coffee Maker 46290 has the lowest rated power of the coffee makers in our data, and neither station can run it:

The same goes for every microwave in our data. One thing does squeeze in. The EcoFlow WAVE 2 fits under both inverter limits at its rated cooling input, but not at maximum cooling:

We wouldn’t build a trip around that. The runtime is short, the margin is thin, and EcoFlow doesn’t publish a startup figure for the WAVE 2, so we can’t check the start against either station. On the RIVER 3 Plus we can’t check it at all.

Picking between them

Pick the RIVER 3 Plus if you want the slightly bigger battery and you’ll be charging from a panel big enough to use its higher solar limit. Pick the EB3A if you plan to plug in something with a motor or compressor and want a published surge rating to check it against. For a CPAP, a Starlink Mini or a laptop, the hours are close enough that neither of those should be what decides it.

We don’t carry weight, size, port layout or wall charging speed in our data. For stations this small, those are often the reason people pick one, so check both manuals.
