What each line is for

Two lines, two different jobs

EcoFlow DELTA

DELTA is EcoFlow's mainstream line and the backbone of its ecosystem. It’s designed to be placed and built upon — expansion batteries across nearly the whole range, a large outlet count, and tight integration with EcoFlow's panels and smart home hardware. It expects to become part of a larger setup over time.

Jackery HomePower

HomePower is Jackery's newer backup line, and it takes the opposite approach to the same job: fewer models, each engineered hard. It carries the longest-lived cells and the highest energy density we measure, and it’s built to sit in one place doing the same duty for years.

The comparability question

Are these two lines even competing?

Before asking which is better, it's worth asking whether they overlap at all.

This is one of the most closely matched cross-brand pairings we’ve. The two lines occupy nearly the same capacity band, hold the same power character, carry the same surge headroom and switch over to battery equally fast. Several models sit directly against each other on both capacity and output.

That makes them genuinely substitutable across most of their range — which is unusual, and worth saying plainly. The choice isn’t about capability. It comes down to two things: how many years of daily cycling you need, and whether you want the option to add capacity later.

Fig. 1 — Every EcoFlow model in both lines, by capacity and output. The two lines form separate clusters — the narrow band where they touch is the only place the choice is genuinely close.

The short version

These two share 83% of their capacity range, and 6 of the 16 models between them land on a genuine head-to-head. This is one of the closer calls on the site — you could be happy with either, so what decides it is going to be something other than size.

The deep dive

What actually separates them

Five specifications that decide which line fits — and one that doesn't.

Lifespan

A cycle is one full discharge and recharge, and the rating is roughly how many you get before capacity settles to about 80% of new. The gap only bites in proportion to how often you cycle: occasional use will never reach either rating, while daily use reaches them in a predictable number of years.

DELTA

3,000

HomePower

6,000

HomePower is rated for double DELTA's cycles — the largest longevity gap between any two lines in this comparison set. For a unit cycled every day that’s the difference between roughly eight years and well over a decade. For a unit used during occasional outages it’s close to irrelevant, and should not drive the decision.

Room to grow

Expandability is whether a unit accepts a second battery later. It separates a finished appliance from the first component of a larger system.

DELTA

91%

HomePower

60%

DELTA leads here and it’s the clearest argument in its favour. Nearly the whole line takes another battery, against a smaller majority of HomePower. If capacity is a decision you’d rather defer, DELTA gives you more room to defer it.

Fig. 2 — How much of each line can grow later. A sealed unit's ceiling is the box you bought; an expandable one lets you defer the capacity decision — which is the axis buyers most often discover they cared about a year on.

Carry weight

Watt-hours per pound is how much energy you get for what you have to lift. For units that live in one place this matters less than it sounds — but it still decides whether one person can reposition it alone.

DELTA

39.8 Wh/lb

HomePower

48.5 Wh/lb

HomePower is the denser line, and by a clear margin — it’s the densest in our catalog. Neither line is portable in any meaningful sense, but a HomePower unit is the easier of the two to move once installed.

Power characterNo difference

Output divided by capacity describes what kind of tool a unit is. A high ratio means a large inverter on a modest pack; a low ratio means endurance.

DELTA

1.17 W/Wh

HomePower

1.17 W/Wh

Identical. For a given size these two lines will start and run the same things in the same way, which is exactly why this pairing comes down to longevity and expansion rather than capability.

Fig. 3 — Output per watt-hour, every model, highest first. High bars are burst tools — they start demanding appliances but do not run them long. Low bars are endurance tools. Two units with the same capacity can sit at opposite ends of this chart.

Switchover speedNo difference

When utility power drops, a unit with UPS passthrough takes over — but not instantly. Under about 10ms almost nothing notices; around 20ms sensitive gear can blink.

DELTA

10ms

HomePower

10ms

Identical, and both sit in the safe band. Whatever you’re protecting — a desktop, a router, a CPAP — switchover isn’t a reason to choose between these two lines.

Balance sheet

What each line is good at, and what it isn't

EcoFlow DELTA

Strengths

Nearly the whole line accepts an expansion battery, so capacity stays a deferred decision
Roughly double the outlet count of a comparable portable, for running several things at once
The broadest ecosystem here — panels, smart home panels and a ladder of larger lines above it
Same power character and switchover speed as HomePower, so nothing is given up on capability

Limits

Half the cycle rating of HomePower, which compounds under daily use
Less energy-dense, so a comparable unit is physically heavier to reposition
Eleven models with overlapping names make the line harder to navigate than it should be
Growing it means buying into EcoFlow's expansion hardware specifically

Jackery HomePower

Strengths

Double the cycle rating — among the longest-lived lines we track
The most energy-dense line we measure
A tight five-model range that’s far easier to choose from
Matches DELTA on power character, surge headroom and switchover speed

Limits

A smaller share of the line accepts an expansion battery
Only five models, so less choice if your requirement falls between sizes
Starts higher than DELTA does, with no smaller option in the line
A newer line with less field history behind it

How to read this

A limit isn't a fault — it's a constraint on what a line is built to do. Every line here has them, including whichever one suits you. The useful question is which set of limits you'll never notice.

The contested band

Where the lines actually collide

Models within 15% of each other on capacity — and whether they're truly interchangeable.

The verdict

So which one should you buy?

Nobody actually buys a spec sheet. Find the row that sounds most like your life — that's the line we'd point you at, and why.

Daily cycling — off-grid living or a solar-first household

Double the cycle rating is worth years of service when the unit works every day.

HomePower

A backup setup you expect to expand

Nearly every DELTA takes another battery; fewer HomePower units do.

DELTA

Occasional outage insurance

At that duty cycle the lifespan gap never arrives, and DELTA gives you more sizes and more outlets.

DELTA

Running several appliances at once

Outlet count decides this more often than capacity does.

DELTA

A unit you may need to reposition alone

HomePower is the densest line we measure — less weight for the same energy.

Common questions

EcoFlow DELTA vs Jackery HomePower series FAQs

Is EcoFlow DELTA or Jackery HomePower better?

They’re unusually closely matched — identical power character, surge headroom and switchover speed, and overlapping capacities. HomePower is rated for double the charge cycles and is more energy-dense. DELTA expands more readily and offers more outlets and a broader ecosystem. If the unit will cycle daily, HomePower's lifespan lead is the strongest argument on the table; if it’s occasional backup you expect to grow, DELTA is.

Which lasts longer, DELTA or HomePower?

HomePower, by a factor of two on the cycle rating. In practice that’s the difference between roughly eight years and well over a decade of daily cycling. If the unit only runs during occasional outages, neither will reach its rating in any realistic ownership period and the difference should not drive your decision.

Can both lines back up a home?

Yes, and at similar capability — they hold comparable capacity, the same power character and the same switchover speed, so both will carry a fridge, a router and lighting through an outage. The differences are longevity, expandability and how much each weighs for the energy it holds.

Which is easier to expand?

DELTA. Nearly every model in the line accepts an expansion battery, against a smaller majority of the HomePower line. DELTA also sits inside a wider ecosystem with larger lines above it, so there’s a further upgrade path if your needs outgrow it entirely.

Do they switch over fast enough for a CPAP?

Both do, equally. The two lines have identical switchover speeds, comfortably inside the range where sensitive equipment should not notice the cutover. This is one variable you can remove from the comparison.
