Jackery HomePower vs EcoFlow DELTA: 2026 Home Backup

EcoFlow's DELTA line has dominated the home-backup conversation for a few years, but it's no longer running unopposed. Jackery officially announced its expanded HomePower Series of home backups on June 17, 2026, with availability beginning June 23 through Jackery and Amazon. The three new models — HomePower 3600 Pro Max, 2000 Plus v2, and 1000 v2 — are aimed squarely at the same buyers shopping EcoFlow's DELTA 3 and DELTA Pro units. This is a direct ecosystem challenge, and the specs are worth a side-by-side read before you commit.

The reason brand choice matters more than it looks: expansion batteries and accessories don't cross-connect. Once you buy into a HomePower or a DELTA, the cost-effective path to more capacity is more of the same brand's hardware. So the decision isn't just which unit wins today's spec sheet — it's which ecosystem you want to be locked into for the next several years of expansion. This post walks the HomePower lineup model by model and frames where each fits against EcoFlow's DELTA equivalents.

The HomePower 3600 Pro Max: charging is the headline

The flagship HomePower 3600 Pro Max leads on charge speed. It accepts up to 4,000W of AC input and fully charges in as little as 80 minutes, plus up to 1,200W of DC/solar input for off-grid topping. That 4,000W figure is genuinely aggressive — many competing units cap AC charging well below it — and it changes how the unit behaves in a storm. When the grid flickers back for an hour between outages, a 4,000W charge rate lets you refill a large battery before the next failure, rather than catching only a partial top-up.

For storm-season and rolling-blackout scenarios, fast charging is underrated. A big battery that takes six hours to refill is half-useless if your grid windows are short; one that refills in 80 minutes turns every brief restoration into a full reset of your backup reserve. EcoFlow's DELTA Pro 3 and DELTA Pro Ultra units also charge quickly, but the 3600 Pro Max's 4,000W AC ceiling is at the top of the class. If you live somewhere with frequent short outages punctuated by brief grid windows, that spec alone may decide the purchase.

The HomePower 2000 Plus v2: expandable and lighter

The mid-tier HomePower 2000 Plus v2 is the volume model, and its two headline claims are 2,400W output with expandable capacity up to 12kWh, and a weight 21 pounds lighter than its predecessor. The 12kWh ceiling matters because it puts the unit in genuine whole-home-essentials territory — enough to carry a fridge, lights, networking, and a few larger loads through a multi-day outage when fully expanded. This is the model that competes most directly with EcoFlow's expandable DELTA 3 and DELTA Pro 3 stacks.

The 21-pound weight reduction is more meaningful than it sounds. Home backup units live in the awkward middle: too heavy to be truly portable, but you still have to move them into position, carry them to the car for a trip, or reposition during an install. Shaving 21 pounds off a unit in this class is the difference between a one-person and a two-person lift. The decision of when expandable capacity is worth the premium over a single fixed unit is exactly the trade-off we work through in whole-home modular storage and smart-panel integration.

The HomePower 1000 v2: the seamless-UPS unit

The entry HomePower 1000 v2 targets the always-on-electronics use case. Jackery cites up to 57 hours of added runtime and a sub-10ms UPS switchover — fast enough that computers, modems, routers, and other sensitive gear never register the grid drop and keep running without a reboot. For a home office or a networking closet, that's the spec that matters most: you want the transfer to be invisible, not just fast.

Sub-10ms switching is competitive with EcoFlow's DELTA units, which offer similar sub-20ms to sub-10ms transfer. In practice, anything under roughly 20ms is seamless for most electronics, so both brands clear the bar for protecting computers and routers. The differentiator at this tier is less about the switchover number and more about runtime, port selection, and how the unit fits your desk. The 1000 v2 is the model to look at if your goal is keeping a workstation and internet alive through brief outages rather than backing up the whole house.

How the lineup maps onto EcoFlow's DELTA range

Lined up against EcoFlow, the HomePower series fills the same three rungs: the 1000 v2 against the DELTA 3 / DELTA 3 Plus class, the 2000 Plus v2 against the expandable DELTA 3 Max and DELTA Pro 3, and the 3600 Pro Max against EcoFlow's larger DELTA Pro units. Jackery's sharpest spec advantage is the 3600 Pro Max's 4,000W charging; EcoFlow's counter is breadth — a deeper accessory ecosystem, smart home panel integration, and a more mature monitoring app.

EcoFlow's software maturity is a real factor for anyone who wants to actually monitor their backup rather than just own it. The DELTA app and Powerinsight hardware give detailed per-circuit visibility and scheduling that we cover in our EcoFlow app and Powerinsight 2 monitoring guide, and the wider 2026 EcoFlow hardware story is laid out in our EcoFlow 2026 lineup overview. Jackery will need to match that software depth to win over buyers who treat the power station as a managed energy system, not just a battery.

Which ecosystem should you commit to?

Buy on the spec that maps to your actual failure mode. If your outages are frequent and short with brief grid windows, the HomePower 3600 Pro Max's 4,000W charging is the strongest single argument either brand makes. If you want maximum expandable capacity in a unit you can still move, the 2000 Plus v2's 12kWh ceiling and weight cut are compelling. If you mainly want a seamless UPS for a home office, both brands' sub-10ms tiers are effectively tied, so decide on runtime and ports.

The one rule that overrides spec-sheet nitpicking: if you already own expansion batteries from one brand, stay in that ecosystem. They don't interconnect, so switching means re-buying accessories you already own. For new buyers with no existing hardware, both Jackery HomePower and EcoFlow DELTA are credible 2026 choices — pick the unit whose headline spec matches your worst outage, and weigh EcoFlow's more mature monitoring software against Jackery's fast-charge edge.
