Main trade-off
EcoFlow RIVER 2 Pro
The 220W solar input is the same ceiling as RIVER 2 Max despite carrying 50% more battery energy.
Head-to-head
Choose RIVER 2 Pro for easier travel with small appliances. AC180 is the step up for supported loads above 800W and a longer built-in reserve.
Before you choose
For a steady 300W load, EcoFlow RIVER 2 Pro models to about 2 hours and BLUETTI AC180 to 3.1 hours.
What this is based on
Hours = nominal Wh × 0.8 / 300W. Inputs 768Wh and 1152Wh. The 80% factor is a shared planning allowance for unusable energy and conversion losses, not a measured efficiency. Idle draw, temperature and the real load change runtime.
Main trade-off
The 220W solar input is the same ceiling as RIVER 2 Max despite carrying 50% more battery energy.
Main trade-off
At about 35.27 pounds, it is substantially heavier than newer 1kWh models. It has only one USB-C port.


Choose RIVER 2 Pro for easier travel with small appliances. AC180 is the step up for supported loads above 800W and a longer built-in reserve.
The output jump is larger than the capacity jump
Winner by situation
RIVER 2 Pro weighs 18.2 lb against 35.27 lb. Saving 17.07 lb is useful for a longer walk, provided its 800W rating and 768Wh battery cover the trip.
AC180 provides 1,800W continuous output against 800W for RIVER 2 Pro. Choose it for a 1,000W running appliance only after checking startup demand and outlet requirements.
The shared planning case gives 2 hours from EcoFlow RIVER 2 Pro and 3.1 from BLUETTI AC180. Measure actual wattage before choosing a required overnight reserve.
The maximum input is 220W for EcoFlow RIVER 2 Pro and 500W for BLUETTI AC180. Compare your actual panel strings with the voltage and current limits as well as this total.
What matters in practice
For a steady 300W load, EcoFlow RIVER 2 Pro models to about 2 hours and BLUETTI AC180 to 3.1 hours.
Hours = nominal Wh × 0.8 / 300W. Inputs 768Wh and 1152Wh. The 80% factor is a shared planning allowance for unusable energy and conversion losses, not a measured efficiency. Idle draw, temperature and the real load change runtime.
EcoFlow RIVER 2 Pro stores about 42.2 nominal watt-hours per pound, compared with 32.7 for BLUETTI AC180.
Nominal energy divided by published weight: 768 / 18.2 and 1152 / 35.27. This compares stored energy per lifting weight, not measured efficiency or handle comfort.
AC180 adds 125% continuous output and 50% nominal capacity over RIVER 2 Pro, while adding about 94% weight.
1800 / 800 - 1 = 1.25. 1152 / 768 - 1 = 0.5. (35.27 / 18.2 - 1) × 100 = 93.8%.

EcoFlow, EFR620
A 768Wh camping station with 800W continuous AC output and a useful 100W USB-C port. It adds battery reserve without reaching full 1kWh weight.

BLUETTI, AC180
A 1,152Wh station with four US AC outlets, a wireless charging pad and a 1,800W inverter. Its extra battery reserve comes with a notably heavier carry.
Meaningful differences
| What changes | EcoFlow RIVER 2 Pro | BLUETTI AC180 | Why it matters |
|---|---|---|---|
| Nominal battery energy | 768 Wh | 1152 Wh | Stored energy determines the starting runtime budget. |
| Continuous AC output | 800 W | 1800 W | This is the sustained rating used for load screening, separate from surge and boost modes. |
| Lifting weight | 18.2 lb | 35.27 lb | Wheels help on flat ground. A trunk, step or shelf still requires a lift. |
| Maximum solar input | 220 W | 500 W | The panel voltage, current and per-port limits must also fit. |
| Dedicated battery expansion | Fixed base capacity | Fixed base capacity | Charging from an external source is different from integrated battery expansion. |
| Published transfer limit | 30 ms | 20 ms | Verify the exact connected device. A short transfer specification does not guarantee uninterrupted operation for every load. |
What you give up
What matters in practice
AC180 more than doubles the continuous inverter rating from 800W to 1,800W, while battery capacity increases by half.
AC180 weighs 35.27 pounds versus 18.2. It suits a vehicle or fixed position better than a long walk to a picnic spot.
AC180 supports 500W solar against 220W for RIVER 2 Pro. That benefit requires enough compatible panel area and usable sunlight.
What the facts say
Useful conclusions from the current portable power stations comparison, followed by the checked facts used to reach them.
Only 6 of 50 models checked match every need here: “I want power for campsites and weekends away”, “I need backup for household essentials”, and “Solar is a real part of my recharge plan”.
6 matching models from 50 checkedBLUETTI AC180 lists 1,800 W for rated AC output, 125% above EcoFlow RIVER 2 Pro at 800 W.
Match countThe count uses the current product-to-need assignments for “I want power for campsites and weekends away”, “I need backup for household essentials”, and “Solar is a real part of my recharge plan”. A need with no documented match does not count.
Calculation noteRated continuous output is used. Surge and voltage-lowering boost modes are excluded. 47 of 50 models have comparable published figures for context.
