Specifications are manufacturer rated as listed.
Capacity and expandability
The EcoFlow lists 3072Wh expandable to 11kWh with extra batteries, while the Anker lists 1,024Wh with no expansion stated. For multi-day blackouts, RV living or extended off-grid trips, the EcoFlow’s expandability is the deciding factor: add batteries as your needs grow. For a weekend trip, a single day of backup, or keeping essentials running during a short outage, the Anker’s 1,024Wh covers phones, laptops, lights and small appliances without the extra batteries.
Output power
The EcoFlow lists 3600W continuous with 7200W surge, enough for heavy-duty appliances and power tools. The Anker lists 2,000W with 3,000W peak across 10 ports. If you run a refrigerator, power tools or an RV air conditioner, the EcoFlow’s headroom matters. For laptops, phones, lights and a small fridge, the Anker’s 2,000W is enough.
Solar input
The EcoFlow includes a 400W solar panel, while the Anker includes a 100W bifacial panel. The Anker lists 1.8-hour solar recharging with 600W of solar input at 60V max. More panel watts means faster solar recharging, so the EcoFlow refills its larger battery faster in good sun. The Anker’s 100W panel suits topping up rather than full recharges.
Weight and portability
The Anker weighs 24.9 lb, while the EcoFlow weighs 125 lb. The Anker is built to carry, store and move around; the EcoFlow is built to sit in a garage or utility room. If you load the station into a truck or carry it to a campsite, the Anker’s weight is the clear advantage. If it never moves, weight does not matter.
Ports and outlets
The Anker lists 10 ports against the EcoFlow’s 4, which matters when several devices charge at once. Ten ports across 2,000W means phones, laptops, lights and a small appliance can all plug in without unplugging something else. Four ports on the EcoFlow is fewer, but each can draw from a larger 3600W pool. If you run many small devices, the Anker’s port count wins; if you run a few big ones, the EcoFlow’s per-port headroom wins. Neither listing fully breaks down the port types, so check the specific outlets against your plugs.
Recharge speed
The Anker lists a full recharge in 49 minutes using HyperFlash at 1,600W, enabled in the Anker app. The EcoFlow lists 80% in under an hour with X-Stream fast charging. Both are fast by power station standards, but they measure differently: the Anker gives a full-charge time while the EcoFlow gives an 80% time. For solar recharging, the Anker lists 1.8 hours with 600W of solar at 60V max. Faster recharge matters most when the station cycles daily; for occasional backup use, either is fast enough.
What the listings leave unclear
Neither listing states a cycle life figure. The Anker lists LiFePO4 chemistry while the EcoFlow lists LFP, which are the same chemistry under different names. The EcoFlow lists 4 ports while the Anker lists 10, but neither breaks down the port types fully. Both list a 5-year warranty term.

Solix C1000 Gen 2 vs Ecoflow Delta 3: which should you choose?
For home backup and maximum power, the EcoFlow DELTA 3 Ultra Plus is the pick: more capacity, more output and expandability for multi-day outages. For portability and fast recharging on the move, the Anker SOLIX C1000 Gen 2 is the pick: lighter, more ports and a 49-minute recharge for campsites and road trips. The right choice depends on whether the station stays home or travels, and on whether you value watts or weight more.
Sizing Notes
- Add up the watts of everything you will run at once, then compare to 2,000W or 3600W.
- Match the solar panel to your sun hours: 400W refills faster than 100W.
- Measure the storage spot: 125 lb needs a permanent place.
- Confirm the ports fit your plugs before you buy.
