The catch
Anker SOLIX C2000 Gen 2
The 58-minute full-charge claim assumes AC and solar together, while charging from US AC alone is listed at 88 minutes.
Side by side
Anker C2000 Gen 2 vs EcoFlow DELTA 2 Max: Base capacity is the same, with Anker easier to lift and DELTA accepting more solar
Quick verdict
For easier lifting and faster transfer, go with the C2000 Gen 2. The DELTA 2 Max fits a bigger solar-input plan, and the base battery capacity is the same.
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 Anker SOLIX C2000 Gen 2 about 5.5 hours and EcoFlow DELTA 2 Max 5.5 hours.
Where this comes from
Inputs of 2048Wh and 2048Wh go into hours = nominal Wh × 0.8 / 300W. The 80% factor is a planning allowance, shared across both, for unusable energy and conversion losses and not a measured efficiency. Runtime depends on idle draw, temperature and the real load.
The catch
EcoFlow DELTA 2 Max
It weighs about 50 pounds, so stairs and repeated lifting are harder than the carry handles imply. It supplies 120V and has no native split-phase 240V output.
Anker SOLIX C2000 Gen 2
- Why pick it
- Carry a two-kilowatt-hour station by yourself
- Put a 10ms transfer specification first
- The catch
- The 58-minute full-charge claim assumes AC and solar together, while charging from US AC alone is listed at 88 minutes.
EcoFlow DELTA 2 Max
- Why pick it
- Feed in more than 800W of compatible solar
- Remain within EcoFlow’s expansion equipment
- The catch
- It weighs about 50 pounds, so stairs and repeated lifting are harder than the carry handles imply. It supplies 120V and has no native split-phase 240V output.

Feed in more than 800W of compatible solar
C2000 Gen 2 stops at 800W, while DELTA 2 Max accepts up to 1,000W of compatible solar input. Before choosing the panels, check voltage, current and individual input limits.

How we worked this out
Inputs of 2048Wh and 2048Wh go into hours = nominal Wh × 0.8 / 300W. The 80% factor is a planning allowance, shared across both, for unusable energy and conversion losses and not a measured efficiency. Runtime depends on idle draw, temperature and the real load.
The return on every pound you carry
EcoFlow DELTA 2 Max stores 41 nominal watt-hours per pound, while Anker SOLIX C2000 Gen 2 stores about 49.1.
How we worked this out
Divide nominal energy by published weight, 2048 / 41.7 and 2048 / 50. That compares stored energy per lifting weight rather than measured efficiency or handle comfort.
8.3 pounds less to lift for the same energy
C2000 Gen 2 keeps the same 2,048Wh and 2,400W baseline as DELTA 2 Max and trims the carry weight by about 17%.
How we worked this out
50 - 41.7 = 8.3 lb, and 8.3 / 50 × 100 = 16.6%. Capacity and continuous output match.
Option A
Anker, A1783
SOLIX C2000 Gen 2
This lighter 2kWh station suits RV and home use and keeps expansion possible. Its two 140W USB-C ports are handy for modern laptops, and the low height can make storing it under a bed easier.
- Best for
- RV owners after 2kWh of capacity who’d rather skip the weight of an older wheeled station.
Facts we checked
- 2400W rated US output, with 2048Wh capacity.
- Measuring 18.1 by 9.8 by 10.1 inches, at about 41.7 lb.
- Solar input of 800W within 11V to 60V and a 17A maximum.
- One 15W port, plus two 140W USB-C ports.
- 1800W US AC charging and 10ms transfer.
- Adding the BP2000 Gen 2 battery expands the system to 4096Wh.
Option B
EcoFlow, EFD350
DELTA 2 Max
This expandable 2,048Wh station has 2,400W output and two independent 500W solar inputs. It works best with equipment that can stay near where it’s parked.
- Best for
- Backup for essentials that can grow, fed by two solar strings
Facts we checked
- 2,400W rated AC output from a 2,048Wh LFP battery

- Supported battery expansion, and two 500W solar inputs each at 11–60V and up to 15A
Spec by spec
Where they really differ
| Spec | Anker SOLIX C2000 Gen 2 | EcoFlow DELTA 2 Max | In practice |
|---|---|---|---|
| Nominal battery energy | 2048 Wh | 2048 Wh | The starting runtime budget comes from stored energy. |
| Continuous AC output | 2400 W | 2400 W | Load screening uses this sustained rating, which is separate from surge and boost modes. |
| Lifting weight | 41.7 lb | 50 lb | Flat ground is where wheels help. A trunk, step or shelf still takes a lift. |
| Maximum solar input | 800 W | 1000 W | Panel voltage, current and per-port limits have to fit as well. |
| Dedicated battery expansion | Supported with compatible equipment | Supported with compatible equipment | Integrated battery expansion is not the same as charging from an external source. |
| Published transfer limit | 10 ms | 30 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 Anker SOLIX C2000 Gen 2
- Only 15W comes from the third USB-C port.
With EcoFlow DELTA 2 Max
- Its older transfer specification is slower than that of the DELTA 3 Plus. If you plan a future upgrade, confirm that expansion batteries are still available before you buy.
Decision guide
How to decide
Pick the C2000 Gen 2 if easier lifting and faster transfer matter. The DELTA 2 Max works for a larger solar-input plan at the same base battery capacity.
Base runtime comes out even
Each stores 2,048Wh and delivers 2,400W continuously. Neither a higher price nor a newer model name buys longer modeled runtime from the base battery.
The biggest day-to-day gap is carry weight
The C2000 Gen 2 weighs 41.7 pounds, versus 50 for the DELTA 2 Max. Every time the station comes off a garage shelf, that difference counts.
Check the sockets before you size solar
Respectively, the maximum solar totals are 800W and 1,000W. The extra 200W only counts if your planned panels and input layout can really deliver it.
What this page can’t tell you
- Treat the runtime figures as planning estimates from published capacity. They are not hands-on discharge tests.
- Don’t wire a station into a home without approved transfer equipment and a qualified installer. A battery station does not guarantee medical continuity.
