The catch
Anker SOLIX C1000 Gen 2
In bypass, its 2,000 W battery output drops to a 1,800 W limit.
Side by side
The C1000 Gen 2 is the pick if you have a 12 V car fridge, a 140 W USB-C device or a running load over 1,800 W. The DELTA 3 Classic makes sense when six direct AC sockets help and its offer is cheaper. Each carries a 1,024 Wh battery and neither can be expanded.
Before you buy
If your fridge needs a 12 V car socket, Anker can run it as long as the draw stays within 10 A and the plug fits. DELTA 3 Classic would need a compatible AC power supply for that fridge, since the station itself has no 12 V output.
Where this comes from
At its car socket, Anker lists 12 V × 10 A = 120 W. EcoFlow explicitly lists no 12 V DC output. Whether an adapter works has to be confirmed by the fridge maker.
The catch
In bypass, its 2,000 W battery output drops to a 1,800 W limit.
The catch
A car fridge cannot connect directly because there is no 12 V DC output.

Anker C1000 Gen 2 against EcoFlow DELTA 3 Classic, looked at through a car fridge, six AC devices and mixed appliance loads. Includes the limits that sit behind the wattage numbers.
The C1000 Gen 2 is the pick if you have a 12 V car fridge, a 140 W USB-C device or a running load over 1,800 W. The DELTA 3 Classic makes sense when six direct AC sockets help and its offer is cheaper. Each carries a 1,024 Wh battery and neither can be expanded.
Which one fits
Anker offers an output that fits. With EcoFlow you need a separate approved AC adapter.
Six direct sockets come with EcoFlow, and their combined demand has to stay under the shared rating.
On battery, Anker goes up to 2,000 W. Check your particular load and connection.
Battery expansion is not supported on either model.
In practice
If your fridge needs a 12 V car socket, Anker can run it as long as the draw stays within 10 A and the plug fits. DELTA 3 Classic would need a compatible AC power supply for that fridge, since the station itself has no 12 V output.
At its car socket, Anker lists 12 V × 10 A = 120 W. EcoFlow explicitly lists no 12 V DC output. Whether an adapter works has to be confirmed by the fridge maker.
Take two hypothetical 1,000 W appliances, which total 2,000 W. That hits Anker's rated ceiling and goes 200 W past EcoFlow's. Leave operating headroom, check startup, and do not treat the socket count as a guide to load.
EcoFlow's total rating is 1,800 W. Anker's is 2,000 W, with a lower 1,800 W bypass limit. 1,000 + 1,000 = 2,000 W.
Anker's high-power port can supply a supported 140 W USB-C profile. EcoFlow stops at 100 W from a single USB-C port, so a device that needs its full 140 W may have to use its AC charger on EcoFlow, which takes up an AC socket too.
The top single-port USB-C output is 140 W against 100 W, which is a 40 W gap. The negotiated rate in practice depends on the device and cable.

Anker SOLIX, C1000 Gen 2
This 24.9-pound, 1,024Wh station has a 2,000W inverter, 140W USB-C and a 49-minute fast-charge mode that you switch on in the app.

EcoFlow, DELTA 3 Classic
This 1,024Wh LFP station keeps things straightforward, with 1,800W output, fast AC charging and a documented 10ms transfer.
Spec by spec
| Spec | Anker SOLIX C1000 Gen 2 | EcoFlow DELTA 3 Classic | In practice |
|---|---|---|---|
| Nominal battery capacity | 1,024 Wh | 1,024 Wh | Stored energy gives no way to tell the two models apart. |
| Rated AC output | 2,000 W total | 1,800 W total | All six EcoFlow sockets draw on a single 1,800 W inverter. |
| 12 V car-style output | 12 V, 10 A, 120 W | None | Anker can connect a compatible DC device with no AC adapter. |
| Maximum USB-C output | 140 W on the high-power port | 100 W and 30 W ports | For a high-power laptop, check the device's power profile and the cable's rating. |
| Maximum solar input | 600 W | 500 W | Anker's input ceiling is 100 W higher, which does not guarantee faster charging. |
| Battery expansion | Not supported | Not supported | With either model, adding a battery later is not how you build a bigger system. |
Trade-offs
Change of plan
Go with Anker SOLIX C1000 Gen 2. DELTA 3 Classic has none, but C1000 Gen 2 does.
Go with EcoFlow DELTA 3 Classic. EcoFlow has six sockets, all inside a shared 1,800 W limit.
Neither model fits. Capacity is fixed on both models.
Decision guide
Go with C1000 Gen 2 if you need to run a 12 V car fridge or a 140 W USB-C device, or if your running load tops 1,800 W. Go with DELTA 3 Classic if six direct AC sockets are handy and its offer has the lower price. Neither 1,024 Wh battery can be expanded.
At a campsite, a car-style DC socket can be worth more than a row of AC outlets. At a desk full of separate chargers, six AC sockets keep things easy. List the plug each appliance really uses and check the combined load. Identical battery capacity doesn't make the connections interchangeable.
EcoFlow gives X-Boost as its own figure, apart from the 1,800 W rated output. That bigger marketing number shouldn't set the budget for electronics, motors or anything that needs a stable rated voltage. The load calculations in this comparison rely on normal rated output.
Neither model supports an extra battery. If your measured daily use is already close to a full kilowatt-hour before losses, plan on recharging or step up to a larger station. With this pair you can't buy the cheaper unit now and add an expansion battery later.
