Choose Anker SOLIX for more output at 1 kWh and a 6,000 W, 240 V home station; choose EcoFlow for stronger solar input at 1 kWh and a 1 kWh model you can expand. Both give 5-year warranties and LiFePO4 batteries on the models we've reviewed.
The short answer: Anker SOLIX vs EcoFlow
Very close at 1 kWh; Anker goes bigger
- Choose Anker SOLIX for the most output and lowest weight at 1 kWh, or a whole-home 240 V station (F3800 Plus).
- Choose EcoFlow if you'll charge from lots of solar or might want more than 1 kWh later.

Charging and solar
Anker is faster from the wall, EcoFlow from the sun
The C1000 Gen 2 fills in about 49 minutes with UltraFast mode switched on in the Anker app (1,200 W normal charging). The Delta 3 Plus fills in about 56 minutes with no setting to change.
On solar, the Delta 3 Plus takes 1,000 W against 600 W for the C1000 Gen 2. The F3800 Plus takes 3,200 W. See what size solar panel you need.
Backup (UPS) and expansion
Same speed at 1 kWh; expansion differs
Both 1 kWh models switch over in about 10 ms, fast enough for most computers. The F3800 Plus is slower at 20 ms.
At 1 kWh, only EcoFlow expands: the Delta 3 series grows to 5 kWh, while the C1000 Gen 2 can't add batteries. For whole-home backup, Anker's F3800 Plus grows to about 53.8 kWh and supplies 240 V.
Battery life and warranty
Tied at 1 kWh
Both brands give 5-year warranties. At 1 kWh, both rate their batteries for 4,000 cycles to 80%; the F3800 Plus is rated for 3,000+ cycles. All use LiFePO4.
