The catch
EcoFlow RIVER 2 Pro
Even though it holds 50% more battery energy, the 220W solar input is the same ceiling as on the RIVER 2 Max.
Side by side
EcoFlow RIVER 2 Pro vs BLUETTI AC180: Carry weight goes up with AC180, which supports steady loads above 800W
Quick verdict
Easier travel with small appliances points to the RIVER 2 Pro. For supported loads above 800W and a longer built-in reserve, step up to the AC180.
Before you buy
Why, and what it costs you
Using a common load makes reserves easier to compare
With a steady 300W load, the model gives EcoFlow RIVER 2 Pro about 2 hours and BLUETTI AC180 3.1 hours.
Where this comes from
Hours = nominal Wh × 0.8 / 300W, with 768Wh and 1152Wh going in. The 80% factor is a shared planning allowance for unusable energy and conversion losses. It does not come from a measured efficiency. Runtime moves with idle draw, temperature and the real load.
The catch
BLUETTI AC180
It weighs about 35.27 pounds, much more than newer 1kWh models, and has just one USB-C port.
EcoFlow RIVER 2 Pro
- Why pick it
- Move the unit a longer distance
- Your appliance demand stays under 800W
- The catch
- Even though it holds 50% more battery energy, the 220W solar input is the same ceiling as on the RIVER 2 Max.
BLUETTI AC180
- Why pick it
- A supported appliance of yours goes above 800W
- Hold more reserve in a single cabinet
- The catch

Move the unit a longer distance
At 18.2 lb versus 35.27 lb, RIVER 2 Pro saves 17.07 lb, which is useful on a longer walk as long as its 800W rating and 768Wh battery cover the trip.

A supported appliance of yours goes above 800W
RIVER 2 Pro is rated at 800W continuous against 1,800W for AC180. A 1,000W running appliance calls for the higher rating, but check startup demand and outlet requirements first.

The battery has to carry a steady 300W load
Under the common planning assumptions, EcoFlow RIVER 2 Pro reaches 2 hours and BLUETTI AC180 reaches 3.1. Measure the real wattage before you pick the overnight reserve you require.

I want solar to refill the battery
EcoFlow RIVER 2 Pro accepts up to 220W of input and BLUETTI AC180 up to 500W. This total is only one check. Your panel strings must also meet the voltage and current limits.

In practice
Differences you will notice
Using a common load makes reserves easier to compare
With a steady 300W load, the model gives EcoFlow RIVER 2 Pro about 2 hours and BLUETTI AC180 3.1 hours.
How we worked this out
Hours = nominal Wh × 0.8 / 300W, with 768Wh and 1152Wh going in. The 80% factor is a shared planning allowance for unusable energy and conversion losses. It does not come from a measured efficiency. Runtime moves with idle draw, temperature and the real load.
The return on every pound you carry
BLUETTI AC180 stores 32.7 nominal watt-hours per pound, while EcoFlow RIVER 2 Pro stores about 42.2.
How we worked this out
These figures are nominal energy over published weight, 768 / 18.2 and 1152 / 35.27. They compare stored energy per lifted weight and not measured efficiency or handle comfort.
Much more power, and nearly double the weight to carry
Over RIVER 2 Pro, AC180 brings 125% more continuous output and 50% more nominal capacity, and about 94% more weight.
How we worked this out
(35.27 / 18.2 - 1) × 100 = 93.8%. 1152 / 768 - 1 = 0.5. 1800 / 800 - 1 = 1.25.
Option A
EcoFlow, EFR620
RIVER 2 Pro
This 768Wh camping station has 800W continuous AC output and a handy 100W USB-C port. You get extra battery reserve without the weight of a full 1kWh unit.
- Best for
- Longer stays powering lights, laptops and a car fridge
Facts we checked
- 800W rated AC output from a 768Wh LFP battery
- 100W USB-C and regulated 12.6V DC output, at about 18.2 lb
- An advertised 70-minute AC recharge, plus 220W solar input at 11–50V and up to 13A
Option B
BLUETTI, AC180
AC180

Spec by spec
Where they really differ
| Spec | EcoFlow RIVER 2 Pro | BLUETTI AC180 | In practice |
|---|---|---|---|
| Nominal battery energy | 768 Wh | 1152 Wh | The starting runtime budget comes from stored energy. |
| Continuous AC output | 800 W | 1800 W | Load screening uses this sustained rating, which is separate from surge and boost modes. |
| Lifting weight | 18.2 lb | 35.27 lb | Flat ground is where wheels help. A trunk, step or shelf still takes a lift. |
| Maximum solar input | 220 W | 500 W | Panel voltage, current and per-port limits have to fit as well. |
| Dedicated battery expansion | Fixed base capacity | Fixed base capacity | Integrated battery expansion is not the same as charging from an external source. |
| Published transfer limit | 30 ms | 20 ms | Check the exact device being connected. Even a short transfer specification can’t guarantee that every load runs without interruption. |
Trade-offs
What each pick costs you
With EcoFlow RIVER 2 Pro
- This page covers the 768Wh Pro. The 716Wh Pro 700 is a different model. Keep combined steady loads under 800W, and check motor startup on its own.
With BLUETTI AC180
- In ambient temperatures of 86–104°F, BLUETTI caps continuous output at 1,500W. The 2,700W lifting mode isn’t a general continuous rating.
Decision guide
How to decide
Pick the RIVER 2 Pro for easier travel with small appliances. Step up to the AC180 for supported loads above 800W and a longer built-in reserve.
Output rises more than capacity does
The AC180 takes the continuous inverter rating from 800W to 1,800W, more than double, while battery capacity grows by half.
Weight nearly doubles as well
The AC180 comes in at 35.27 pounds, against 18.2. It’s a better fit for a vehicle or a fixed position than for a long walk to a picnic spot.
In the right setup, solar can refill the larger unit faster
The AC180 takes 500W of solar, versus 220W for the RIVER 2 Pro. You only get that benefit with enough compatible panel area and usable sunlight.
What this page can’t tell you
- These runtime figures are planning estimates from published capacity. None come from hands-on discharge tests.
- Never tie a station into home wiring unless you have approved transfer equipment and a qualified installation. A battery station does not guarantee medical continuity.
