Nobody is incentivised to tell you the old model is the better buy. The manufacturer wants to move current stock. Review sites chase launches, because that’s where the traffic is. So the outgoing unit sitting at a real discount tends to go unmentioned, right up until it sells out.
That gap is worth money. Sometimes a few hundred dollars for a unit that does the same job. But it is genuinely a case-by-case call, and the wrong version of this decision leaves you with an orphaned platform.
The test, in one line
The discount has to be bigger than the spec gap, and the discount is measured against what the replacement costs today, not against the old model’s original MSRP.
A retailer marking a discontinued unit down from its launch price is telling you nothing. The only number that matters is what you’d pay for the current-generation unit that does the same job.
Where each one lands right now#
Checked 2026-08-07 against manufacturer listings. All capacity, recharge, and output figures are manufacturer claims Spec unless badged otherwise.
$1,049, against $1,199 for the DELTA 3 Max that replaced it. Identical 2,048Wh. Full recharge in 1.1 hours, which beats the BLUETTI AC200L's 90–100 minutes at the same capacity. Expandable to 6,144Wh.
$150 cheaper for the same watt-hours, and the spec gap against the DELTA 3 Max is small enough that the discount clearly wins. The catch is delivery: it's sold out direct and listed as pre-order shipping mid-September. A discount you can't take delivery of isn't a discount, so check the date before committing.
The DELTA 3 Classic replaced it at $529 with the same 1,024Wh, 60 minutes to full instead of 80, and a 3,600W surge instead of 2,200W. There is no spec on which the DELTA 2 wins.
That's a real gap, so the discount has to be real too. My line is somewhere under $400. At that price you're getting a competent 1kWh LiFePO4 unit with a fast charger for less than anything current, and most buyers never think to look. Anywhere near $529 and you're paying current-generation money for a slower unit.
This one isn't old-versus-new. EcoFlow retired the size class, not just the model. The RIVER 2 Pro is 768Wh; the RIVER 3 Max that follows it is 572Wh. They shrank the slot rather than upgrading it, so there's nothing to compare against.
EcoFlow's own product page for it is gone as of 2026-08-08, though Amazon still stocks them. If 768Wh in 70 minutes is what you want, buy it while it exists. The BLUETTI AC70 is the closest thing still in production at the same 768Wh, and at $359 it is a tier cheaper.
The example that shows where this stops working. I ran one full-time for seven years Measured, so this isn't a spec-sheet opinion, and I wouldn't buy one new today at any price.
It's NMC, not LiFePO4: fewer cycles, worse heat behaviour, and it locked up on me every Colorado winter. The 25-hour wall charge is the whole reason this site ranks by recovery speed, and it's worth seeing how far the category has moved since 2018 before buying anything from that era. Used at $300–400 with verifiable history it's a fine backup unit. That's the ceiling.
The three risks nobody prices in#
1. Expansion batteries disappear before the base unit does +
This is the one that actually bites. Expandability is a headline feature on most 1kWh-and-up units, and it's worthless the moment the add-on packs stop being made. The packs are lower-volume than the base units, so they tend to go first.
If any part of your reasoning is "I can add capacity later," verify the pack is in stock before you buy the base unit. Not that it exists, but that you can order one today.
2. Firmware and app support get quietly deprioritised +
Nobody announces the end of support for a power station. It just stops appearing in release notes. If the unit's monitoring lives in a phone app, that app will keep being updated for the current lineup and eventually stop accounting for yours.
This matters less than it sounds if you treat the app as a convenience. It matters a lot if app-driven monitoring was part of why you picked the brand. The stated warranty term is the commitment you can actually hold them to. EcoFlow's is five years on the units above.
3. "Discontinued" and "sold out" are not the same thing +
Worth saying plainly, because I got this wrong myself earlier this year. A product page that 404s, or a unit that vanishes from a collection page, usually means a URL change or an inventory gap, not the end of the product.
Twice this year a manufacturer URL returned a perfectly healthy 200 while serving a different product entirely. A status check passes; the link is still wrong. The only reliable method is opening the page and reading what's on it, which is what every figure here is based on.
