Two expandable ~2 kWh LiFePO4 boxes shoppers actually cross-shop. Anker’s SOLIX C2000 Gen 2 is the lighter 2400 W suitcase with BP2000 Gen 2 expansion. EcoFlow’s DELTA 3 Max Plus is the heavier 3000 W chassis that scales toward 10 kWh. Same headline watt-hours; different inverter and expansion stories.
Anker SOLIX C2000 Gen 2
EcoFlow DELTA 3 Max Plus
| Spec | Anker SOLIX C2000 Gen 2 | EcoFlow DELTA 3 Max Plus |
|---|---|---|
| Capacity | 2048 Wh | 2048 Wh |
| AC output | 2400 W rated AC, 4000 W peak (Anker SOLIX US) | 3000 W rated AC, 6000 W surge; X-Boost up to 3800 W (US store)Higher |
| Weight | 18.9 kg / 41.7 lbLighter | Approx. 22.1 kg (EU tech sheet); confirm North American sheet |
| Chemistry | LFP (LiFePO4) | LFP (full-tab / CTC — EcoFlow marketing) |
| Cycle life (mfr.) | 4000 cycles to 80% capacity (Anker datasheet / US PDP) | EcoFlow markets ~10-year lifespan under proper use; numeric cycle count not fully tabulated on the US PDP we fetched |
| Max solar input | 800 W max PV / XT60i (11–60 V, 17 A) | 1000 W max (2×500 W) on EU/UK spec tablesHigher |
| Expandable | Yes — up to ~4 kWh (4096 Wh) with BP2000 Gen 2; up to 5120 Wh with BP3000 (Anker) | Yes — up to 10 kWh with listed extra batteries (EcoFlow US/EU) |
| Charge temp. | 32–104°F (0–40°C) charging (US PDP) | 0–45°C (EU tech sheet) |
| Discharge temp. | Recharging/operating window on US PDP lists −4–104°F for one row — confirm discharge band in the manual | −10–45°C (EU tech sheet) |
| Warranty (mfr. copy) | Unknown numeric years on the US PDP we fetched; Anker markets a 10-year lifespan slogan | 3+2 years (EcoFlow regional marketing) |
Capacity is a tie; watts are not
Both list 2048 Wh. EcoFlow rates 3000 W continuous (6000 W surge; X-Boost up to 3800 W on the US store). Anker rates 2400 W continuous / 4000 W peak. That 600 W continuous gap decides whether a heavy kitchen or tool load is even allowed before you talk about runtime.
Expansion
Anker lists pairing with a BP2000 Gen 2 to about 4096 Wh (marketed as ~4 kWh), or up to 5120 Wh with BP3000. EcoFlow lists scaling from about 2–10 kWh with compatible extra batteries. Modular kits cost money and floor space — the base box is only the start of the bill.
Weight
Anker’s US sheet: 18.9 kg / 41.7 lb. EcoFlow’s EU tech sheet: about 22.1 kg — confirm the North American sheet before you plan a one-hand carry. That ~3 kg gap is real on paper even before you add expansion batteries.
Solar and AC input
Anker: 800 W max PV (XT60i, 11–60 V, 17 A); AC in up to 1800 W with manufacturer claims of ~58 min 0–100%. EcoFlow EU/UK tables: 1000 W solar (2×500 W); AC in up to 2300 W on the EU sheet (~68 min 0–100% claim) — confirm the North American inlet rating. EcoFlow wins solar headroom on the sheets we used; Anker’s AC recharge claim is slightly faster on paper.
Cycles and warranty honesty
Anker: 4000 cycles to 80% (datasheet / US PDP). EcoFlow markets a ~10-year lifespan under proper use; a numeric cycle count was not fully tabulated on the US PDP we fetched — treat as unknown here, not as a win. Anker warranty years: unknown on the US PDP we fetched. EcoFlow regional marketing lists 3+2 years. Read the policy at purchase.
