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
EcoFlow RIVER 2 Pro vs Anker SOLIX C1000: C1000 adds appliance headroom and expansion, RIVER carries lighter
The short answer
Choose RIVER 2 Pro for a lighter small-appliance kit. C1000 suits higher-power equipment and a future compatible expansion battery.
Before you choose
The reasoning and the trade-offs
A common load makes the reserve easier to compare
For a steady 300W load, EcoFlow RIVER 2 Pro models to about 2 hours and Anker SOLIX C1000 to 2.8 hours.
What this is based on
Hours = nominal Wh × 0.8 / 300W. Inputs 768Wh and 1056Wh. 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
Anker SOLIX C1000
It is heavier and has a lower continuous AC rating than C1000 Gen 2. The generations do not share the same expansion path.

Winner by situation
Start with what you need it to do
Keep the main unit easier to carry
RIVER 2 Pro weighs 18.2 lb against 28.44 lb. Saving 10.24 lb favors longer carries when its 800W output and 768Wh capacity are enough.
- EcoFlow RIVER 2 Pro
- Better fit
- Anker SOLIX C1000
- Depends
Run a supported load above 800W
C1000 provides 1,800W continuous output against 800W for RIVER 2 Pro. A 1,000W running load needs the C1000 rating, plus a check of startup and outlet limits.
- EcoFlow RIVER 2 Pro
- Not suitable
- Anker SOLIX C1000
- Better fit
The battery needs to cover a steady 300W load
The shared planning case gives 2 hours from EcoFlow RIVER 2 Pro and 2.8 from Anker SOLIX C1000. Measure actual wattage before choosing a required overnight reserve.

I want to replenish the battery with solar
The maximum input is 220W for EcoFlow RIVER 2 Pro and 600W for Anker SOLIX C1000. Compare your actual panel strings with the voltage and current limits as well as this total.

What matters in practice
The differences that matter
A common load makes the reserve easier to compare
For a steady 300W load, EcoFlow RIVER 2 Pro models to about 2 hours and Anker SOLIX C1000 to 2.8 hours.
How we reached this conclusion
Hours = nominal Wh × 0.8 / 300W. Inputs 768Wh and 1056Wh. 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.
What you gain for each pound carried
EcoFlow RIVER 2 Pro stores about 42.2 nominal watt-hours per pound, compared with 37.1 for Anker SOLIX C1000.
How we reached this conclusion
Nominal energy divided by published weight: 768 / 18.2 and 1056 / 28.44. This compares stored energy per lifting weight, not measured efficiency or handle comfort.
A 37.5% reserve increase crosses a much bigger load boundary
C1000 adds 37.5% nominal energy over RIVER 2 Pro and raises continuous output by 125%.
How we reached this conclusion
1056 / 768 - 1 = 0.375. 1800 / 800 - 1 = 1.25.
Choice A
EcoFlow, EFR620
RIVER 2 Pro
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.
- Best matched use
- A longer stay with lights, laptops and a car fridge
Checked facts
- 768Wh LFP battery and 800W rated AC output
- About 18.2 lb with 100W USB-C and regulated 12.6V DC output
- 220W solar input, 11–50V at up to 13A, with an advertised 70-minute AC recharge
Choice B
Anker SOLIX, A1761
C1000
The original C1000 pairs 1,056Wh with an 1,800W inverter and accepts a matching expansion battery. It remains useful if growing the battery matters more than trimming weight.
- Best matched use
- A compact backup system with room to add capacity
Checked facts
- 1,056Wh LFP battery and 1,800W rated AC output
- About 28.44 lb, six AC outlets and 100W USB-C
- Supports a matching 1,056Wh expansion battery, up to 600W solar and a 20ms transfer mode
Meaningful differences
What changes the fit
| What changes | EcoFlow RIVER 2 Pro | Anker SOLIX C1000 | Why it matters |
|---|---|---|---|
| Nominal battery energy | 768 Wh | 1056 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 | 28.44 lb | Wheels help on flat ground. A trunk, step or shelf still requires a lift. |
| Maximum solar input | 220 W | 600 W | The panel voltage, current and per-port limits must also fit. |
| Dedicated battery expansion | Fixed base capacity | Supported with compatible equipment | 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
Every choice has a cost
If you choose EcoFlow RIVER 2 Pro
- This is the 768Wh Pro, not the 716Wh Pro 700. Keep combined steady loads below 800W and check motor startup separately.
If you choose Anker SOLIX C1000
- The 600W solar ceiling requires the right panel voltage. Below 32V the input-current limit is 10A, rising to 12.5A from 32V to 60V.
What matters in practice
How to make the call
The larger inverter is the meaningful upgrade
C1000 increases continuous output from 800W to 1,800W. That can admit a different appliance, while the 288Wh capacity gain mainly extends runtime.
Budget the carrying difference
C1000 adds 10.24 pounds. A station that stays in the car makes that easier to accept than a kit carried to a remote pitch.
Solar and battery growth favor Anker
C1000 lists 600W solar against 220W and has a dedicated compatible expansion path. RIVER 2 Pro has a fixed-capacity design.
What this comparison cannot tell you
- Runtime figures are planning estimates from published capacity, not hands-on discharge tests.
- Do not connect a station to home wiring without approved transfer equipment and qualified installation. A battery station is not a medical continuity guarantee.
