EcoFlow vs Anker SOLIX: priced per watt-hour, in AUD
EcoFlow is cheaper per watt-hour at the 1,000Wh and 2,000Wh tiers, where most buyers land. At about 1,000Wh that is $0.98/Wh against $1.42/Wh; at about 2,000Wh, $1.02/Wh against $1.32/Wh. Anker answers with output rather than price: its C1000 Gen 2 delivers 2,000W where EcoFlow's 1,000Wh units deliver 1,800W, which decides whether a kettle or a microwave will run at all. At the 290Wh entry tier both brands charge A$449 and the rate per watt-hour is level, though EcoFlow's unit puts out 600W against Anker's 300W.

Is EcoFlow or Anker SOLIX cheaper in Australia?
Cost per watt-hour is the only figure that makes different capacities comparable, and it is simple arithmetic on a published price. Sorted that way the two ranges interleave, with EcoFlow holding the cheaper slot at 1,000Wh and 2,000Wh and the pair level at the 290Wh entry tier.

Where each one wins
EcoFlow
Cheaper for the same capacity at 1,000Wh and 2,000Wh, and the largest single unit of the two. Choose it if you are buying capacity per dollar, or want one unit that can grow.
Cheapest 1,000Wh: DELTA 3 Classic at A$999
See EcoFlow pricesAnker SOLIX
More continuous output at the 1,000Wh tier, 2,000W against 1,800W. Choose it if the point is running high-draw appliances rather than storing the most energy per dollar.
Most output under A$2,000: C1000 Gen 2 at 2,000W, A$1,599
See Anker SOLIX pricesOutput, not capacity, is what stops a unit working
Capacity in watt-hours tells you how long something runs. Output in watts tells you whether it runs at all. A 2,000Wh unit rated at 1,800W will refuse a 2,400W appliance no matter how full it is. If your reason for buying is a kettle, a microwave, a power tool or a portable air conditioner, read the output column first and the capacity column second.
What we earn, on both sides
Links to EcoFlow and to Anker SOLIX are both affiliate links, so we earn either way and have no reason to prefer one. That is why this page turns on cost per watt-hour: it is arithmetic on prices published by the companies themselves, which you can check in a minute and a commission cannot move. We also earn from Apollo Energy Group on installed home batteries, and both of these brands sell installed systems that compete with Apollo. Our portable versus installed page sets out that overlap.

Common questions
- Is EcoFlow or Anker SOLIX cheaper in Australia?
- EcoFlow at the two tiers most people buy in. At roughly 1,000Wh the EcoFlow DELTA 3 Classic is A$999 against A$1,499 for the Anker SOLIX C1000, which is $0.98/Wh versus $1.42/Wh. At roughly 2,000Wh the DELTA 2 Max is A$2,099 against A$2,699 for the C2000 Gen 2. At the 290Wh entry tier they are level: both charge A$449, for 286Wh and 600W from EcoFlow against 288Wh and 300W from Anker. The gap narrows but does not close at EcoFlow's regular prices, since several EcoFlow models were discounted when these were read on 24 August 2026. Check both before buying.
- Does Anker SOLIX offer anything EcoFlow does not at the same price?
- More continuous output at the 1,000Wh tier. The C1000 Gen 2 delivers 2,000W against 1,800W for EcoFlow's DELTA 3 range, which matters if you intend to run a kettle, microwave or power tool rather than only electronics. Output and capacity are different specifications and the one that stops a unit working is output: a large battery with a small inverter will refuse a high-draw appliance no matter how much charge it holds.
- Which has the bigger unit?
- EcoFlow. Its DELTA Pro Ultra reaches A$7,299 at 6,144Wh and 6,900W, above Anker's largest single unit, the F3800 at A$5,399 for 3,840Wh and 6,000W. Both expand with add-on batteries, so the practical ceiling is higher than either headline figure and the cost per watt-hour of expansion packs is worth checking separately.
- Are these a substitute for an installed home battery?
- No. A portable unit runs a fridge, a router and devices through an outage and needs no electrician, which is why it suits renters and apartments. An installed battery runs circuits, charges from rooftop solar and qualifies for the federal rebate, none of which a portable unit does. We set the two out side by side on our portable versus installed page.
- Does Refer Labs earn from this comparison?
- Yes, from both brands. Cost per watt-hour is arithmetic on prices you can check on each company's own store, so a commission cannot move it. We also earn from Apollo Energy Group on installed batteries, and that is stated wherever the two categories are compared.
