EcoFlow vs Bluetti: Power Stations Compared Size for Size

Bluetti undercuts EcoFlow on price at most sizes and quotes higher cycle ratings; EcoFlow had better stock and more complete published specs when we checked.

The short answer

Bluetti is cheaper per kWh: the Elite 100 V2 was $499 for 1 kWh and the Elite 200 V2 $899 for 2.07 kWh, with 6,000-cycle ratings on the larger models. But both Elite V2 units were out of stock on Bluetti's US site when we checked, and neither expands. For home backup the Bluetti Apex 300 ($1,599 for 2.76 kWh, 3,840 W, 120/240 V) costs far less than the EcoFlow DELTA Pro 3 ($2,799 for 4.1 kWh, 4,000 W) and expands further per unit.

Choose EcoFlow if you need it now (in stock), want a 1 kWh unit that expands, or want a warranty stated on every model (Bluetti's US pages did not state one for the Elite 100 V2 or Apex 300).

Choose Bluetti for the lowest price per kWh and the highest cycle ratings, especially the Apex 300 for home backup.

*Prices and specifications are from each manufacturer's US website, checked . Prices change often, sometimes daily during sales; the seller's page is the final word. Cycle ratings are the maker's own figures, measured to different end points, so treat them as rough guides.

How we compared

We compare only figures the manufacturers publish for their US models, and we link each one below. We have not lab-tested these units. Capacity is the rated battery capacity; usable AC energy is lower, typically by 10 to 20 percent, because of inverter losses. Cycle ratings are each maker's claim to its own end point. See how we choose products.

Specifications and prices are copied from manufacturer websites on the date shown and change often. Confirm them with the seller before buying. See our disclaimer.
