The EcoFlow Delta 2 is the more capable power station; the Jackery Explorer 1000 v2 is the better portable one. This comparison is built on manufacturer specs and owner reports — no bench testing, no borrowed lab numbers — and every figure was checked against the official product pages on October 21, 2026. These are the two roughly-1kWh units US buyers actually cross-shop, even though EcoFlow has moved on to the Delta 3 and the Delta 2 now sits in the lineup as the older-but-still-sold model. The Delta 2 is frequently discounted, so check current price rather than assuming either unit is the cheaper buy.

Capacity and runtime: almost a tie
The Jackery holds 1,070Wh, the Delta 2 holds 1,024Wh. That is a 46Wh gap — about 4.5% — and the least interesting difference between these two machines. Run the numbers.
Runtime in hours = Wh x 0.85 / W. The 0.85 is the inverter-loss factor: no power station delivers its full rated capacity to an AC load, and 15% loss is a fair planning assumption. You can redo any of these with our watt-hour calculator.
Jackery Explorer 1000 v2 — 1,070 x 0.85 = 909.5Wh usable:
- 100W load: 909.5 / 100 = 9.1 hours
- 150W mini-fridge average draw: 909.5 / 150 = 6.1 hours
- 60W CPAP without humidifier: 909.5 / 60 = 15.2 hours
- 190W essentials kit (fridge 150W + router 10W + lights 30W): 909.5 / 190 = 4.8 hours
EcoFlow Delta 2 — 1,024 x 0.85 = 870.4Wh usable:
- 100W load: 870.4 / 100 = 8.7 hours
- 150W mini-fridge average draw: 870.4 / 150 = 5.8 hours
- 60W CPAP without humidifier: 870.4 / 60 = 14.5 hours
- 190W essentials kit: 870.4 / 190 = 4.6 hours
The 46Wh gap buys roughly 20–25 extra minutes at a 100W load — immaterial next to a fridge’s duty cycle, which alone can swing runtime by hours. If fridge backup is the job, start with our refrigerator sizing guide; for sleep therapy, see the CPAP picks. Unsure what size class you belong in? Read how many watt-hours you actually need first.
Winner: a draw, with a token edge to the Jackery — 46Wh more on paper, the same class of machine in practice.
Power output and surge
Here the Delta 2 opens real daylight: 1,800W continuous across six AC outlets with a 2,700W surge, against 1,500W across three outlets and a 3,000W surge for the Explorer 1000 v2.
Outlet count matters more than it sounds. Three AC outlets means a laptop, a lamp and a fridge and you are full — you will be swapping plugs at a tailgate or during an outage. Six outlets is the difference between a power strip and no power strip, a genuine livability feature at a group campsite or a tailgate setup, not a spec-sheet trophy.
The surge numbers run the other way but not far enough to change the verdict. The Jackery’s 3,000W peak helps with motor-start loads — a fridge compressor kicking on, a small saw — but the Delta 2’s higher continuous rating is what you lean on minute to minute, and its X-Boost mode claims up to 2,200W for devices that would otherwise trip the inverter.
Treat X-Boost with caution. It is rated for resistive loads — heaters, kettles, hot plates — not for motor-driven appliances or sensitive electronics, and it is not a substitute for a bigger inverter. Counting on any boost mode to run a compressor-based appliance is how units get tripped.
Winner: EcoFlow Delta 2. More continuous power, twice the outlets, and a boost mode the Jackery simply does not publish an equivalent for.
Charging speed: wall vs solar
This one splits by how you plan to refill.
On wall power, the Jackery is faster to a full battery. Super Charge takes the Explorer 1000 v2 from empty to full in about an hour; the standard AC adapter takes 1.58 hours. The Delta 2’s X-Stream system at 1,200W reaches 80% in roughly 50 minutes but needs 80 minutes to hit 100%. Owners consistently praise the one-hour refill — the most-cited convenience in Jackery owner threads.
On solar, the Delta 2 has more headroom: 500W max input against the Jackery’s 400W. In real midday conditions that gap shows up as a shorter panel session, though both are limited by the sun you actually get. The Jackery’s 400W ceiling is split across two DC 8mm ports — fine for a pair of 200W panels; the Delta 2’s 500W ceiling suits a bigger array. If panels are your primary charging method — an RV setup or an off-grid camp — the Delta 2’s ceiling is the one you want.
Winner: split. Wall charging to a full battery: Jackery. Solar ceiling: Delta 2.
Ports and monitoring
The Delta 2 is the more useful hub. EcoFlow advertises up to 15 devices at once: two 100W USB-C ports, four USB-A (two at 12W, two fast-charge at 18W), two DC5521 barrel outputs at 12.6V/3A, and a 12.6V/10A car port rated to 126W. That is enough for a Starlink Mini, two phones, a laptop, a camera battery charger and a 12V fridge lead simultaneously — see our Starlink Mini power guide if that is your use case.
The Jackery is leaner: one 100W USB-C, one 30W USB-C, a single 18W USB-A and a 12V/10A car port. It covers a phone, a laptop and a 12V accessory, not a family’s worth of devices without a USB hub.
Monitoring: EcoFlow’s app earns consistent praise from owners, who report that the published power limits are accurate in real use. Jackery’s app plus on-unit LCD does the job and is simpler to learn. The honest split is that EcoFlow’s software is the more polished, while Jackery’s interface is easier for a non-technical household member to pick up in an outage.
One caveat repeats in owner reports: fan noise. Delta 2 owners describe the fan as noticeable above a few hundred watts and audible while charging overnight; several keep the unit in a separate room. Jackery rates the Explorer 1000 v2 at 30 dB, and noise is not a common complaint in Jackery threads. If the station lives in a bedroom or a small camper, that difference is real.
Winner: EcoFlow Delta 2 on ports and app, with the noise caveat noted.
Warranty, battery life and value
Both carry five-year warranties. Jackery’s is structured as three standard years plus two extended years when you buy through jackery.com, so confirm the structure wherever you purchase. EcoFlow states a flat five years.
Cycle life is where the marketing gets slippery. Jackery rates the Explorer 1000 v2 at 4,000 cycles to 70% or more of original capacity. EcoFlow rates the Delta 2 at 3,000 cycles to 80% or more. Different endpoints — 70% versus 80% — so the Jackery’s 1,000-cycle edge is not apples to apples, and it shrinks if you hold both to the same end-of-life threshold. Both are LiFePO4 and both are rated for years of daily cycling; neither will be the weak link in a normal use pattern.
Owner reports fill in that picture unevenly. An EcoFlow owner in Ukraine reports two years of daily charge/discharge on a Delta-series unit used as a PC UPS, with no critical degradation. Jackery owners report similar durability — one ran a refrigerator roughly 10 hours during an outage with about 30% remaining, and another has run a desktop PC off an Explorer 1000 v2 as a UPS for around two years, using the battery-saver charge limit to smooth out solar-input switching.
The recurring negative on both sides is support, and it is email-based and slow either way. Jackery owners describe drawn-out back-and-forth over a dead AC port and refusals past the 30-day window; the community counterpoint is that a 30-day refund followed by repair-or-replace is standard and disclosed. The practical advice from both owner bases is identical: test every port in the first 30 days while the refund window is open, keep your receipt, and check whether your credit card doubles the warranty — and see where to buy a portable power station before choosing a seller.
Expansion is the Delta 2’s quiet advantage and its quiet trap. You can take it to 2,048Wh with a DELTA 2 extra battery or 3,072Wh with a DELTA Max extra battery. But EcoFlow’s Canadian storefront now notes the extra battery is no longer available there, so check availability in your region before you buy the Delta 2 planning to expand it later. The Jackery Standard series is not expandable at all — a common wish-list complaint in owner threads.
On value: the Delta 2 is an older model and is frequently discounted, so check current price rather than assuming either unit is cheaper.
Winner: Jackery Explorer 1000 v2 on cycle rating and wall-charge convenience; EcoFlow on expansion potential, if the batteries are still available to you.
Buy the Explorer 1000 v2 if…
- You will actually carry it: at 23.8 lbs against 27, it is the one you will haul to the campsite or the overlanding rig without dreading it.
- You want a full charge in about an hour, not 80 minutes — and you will not bother with a big solar array.
- You need a published sub-20ms UPS switchover for a desktop PC or network gear.
- You are sizing for CPAP, phones and lights, and three AC outlets is enough. Start with the camping picks.
- You would rather have the simpler interface and a quieter unit.
Buy the Delta 2 if…
- You want the most capable ~1kWh box in this matchup: 1,800W, six outlets, 500W solar.
- You are buying for home backup and want the option to add batteries later toward 3kWh — provided the extra battery is available where you live.
- You have a big panel array and want the higher solar ceiling.
- You run a lot of small devices at once — the Delta 2’s 15-port array against the Jackery’s seven.
- You can live with fan noise and 27 lbs in exchange for the spec-sheet win.

Frequently asked questions
Which is better overall, the Jackery 1000 v2 or the EcoFlow Delta 2?
The EcoFlow Delta 2 is the more capable power station, with 1,800W of AC output across six outlets, 500W of solar input and expansion up to 3,072Wh. The Jackery Explorer 1000 v2 is the better portable unit, at 23.8 lbs with a roughly one-hour wall charge and a published sub-20ms UPS switchover. Which one is better for you depends on whether you value raw capability or carryability more.
Which one charges faster?
On wall power the Jackery Explorer 1000 v2 goes from empty to full in about an hour using Super Charge, while the EcoFlow Delta 2 needs 80 minutes to reach 100% but gets to 80% in roughly 50 minutes at its 1,200W X-Stream rate. On solar the Delta 2 wins with a 500W input ceiling against the Jackery's 400W. If you recharge from an outlet, it is close to a tie; if you recharge from panels, the Delta 2 pulls ahead.
Which is better for home backup?
The EcoFlow Delta 2 is the stronger backup box on paper because 1,800W and six AC outlets let you run more of a household at once, and you can add batteries to reach 2,048Wh or 3,072Wh. The Jackery Explorer 1000 v2 publishes a sub-20ms UPS switchover, while EcoFlow describes EPS auto-switching for the Delta 2 without publishing a switchover figure, so check the spec sheet if seamless PC backup is the priority. Either way, both are short-outage tools, not whole-home solutions.
Which battery lasts longer?
Jackery rates the Explorer 1000 v2 at 4,000 cycles to 70% or more of original capacity, while EcoFlow rates the Delta 2 at 3,000 cycles to 80% or more. Because the two brands stop counting at different thresholds, this is not a like-for-like comparison, but on paper the Jackery holds the higher rating. Both carry five-year warranties.
