Both run a house at 7,200W. The real question is where it will live: a utility room, or a freezing garage.
The Jackery Explorer 5000 Plus is one 134.5 lb box: 5,040Wh, 7,200W at 120V and 240V with a NEMA 14-50, 4,000W of solar, and 240V charging only through its Smart Transfer Switch; Jackery rates it for indoor use. The EcoFlow DELTA Pro Ultra is an inverter plus a 6,144Wh battery, 70 lb and 111.8 lb: the same 7,200W, 5,600W of solar, 3,000W charging from a 240V outlet, an IP54 rating and charging down to −4°F. For a heated room, the 5000 Plus does the job for $700 less.
Below: every difference with numbers, a 20-second calculator for your own gear, eight modeled situations, a third option, and what published reports found on each.
Same 7,200W at 120V and 240V. The DELTA Pro Ultra costs $700 more for 1,104Wh more, 5,600W of solar, 3,000W charging from a 240V outlet, an IP54 rating and charging down to −4°F. The 5000 Plus is one box with a 14-50 and a 14,400W surge.
- you start big motors: 14,400W surge
- you want one box indoors
- you use a NEMA 14-50
- it lives in a cold garage
- you charge from a 240V outlet
- you’ll run 5,600W of solar
The five differences that decide it
Both deliver 7,200W at 120V and 240V with an L14-30, have four 20A outlets, take about 30kWh per unit with extra batteries, offer a 0ms online UPS on some outlets and connect to a home transfer panel. These five gaps decide it.

Estimates use 85% usable capacity and 70% of rated solar output. Real results vary with temperature, inverter load, shade and appliance cycling. Fridge and freezer watts are daily averages and do not include compressor startup surges.
Runtime by appliance, one at a time
Simple energy estimates, not measured runtimes. About 4,284Wh usable on the 5000 Plus and 5,222Wh on the DELTA Pro Ultra with one battery.
Appliance for appliance, the Pro Ultra lasts 22% longer than the 5000 Plus.

The price gap, in numbers
The EcoFlow DELTA Pro Ultra (1 battery) costs $700 more than the Jackery Explorer 5000 Plus and adds 1,104Wh: that is $0.63 per extra Wh, against $0.69 per Wh for the 5000 Plus.
Prices refresh daily from Jackery US and EcoFlow US.What the $700 buys: 1,104Wh more battery (6,144Wh vs 5,040Wh), charging and running down to −4°F, and an IP54 rating.
Cycle ratings don’t line up: Jackery rates the 5000 Plus at 4,000 cycles to 70%, EcoFlow the DELTA Pro Ultra at 3,500 to 80%, so we skip the price-per-cycle card. Prices move during the year; the figures here are refreshed daily by our price engine.
The third option: the EcoFlow DELTA Pro 3 at $2,799

Another way to 240V: 4,096Wh, 4,000W at 120V and 240V, 3,600W charging from a 240V outlet, 2,600W of solar, a 10ms UPS and expansion to about 12kWh, at 113.5 lb. OutdoorGearLab measured 3,790Wh out of it. Pick it if your loads stay under 4,000W and you don’t need 30kWh. Our DELTA Pro 3 review goes deeper. See the DELTA Pro 3 at EcoFlow.
Eight modeled situations, worked out
Same formula as the calculator above. The DELTA Pro Ultra carries 1,104Wh more per battery, so it runs about 22% longer on every load; the 5000 Plus answers with surge.
24-hour outage, essentials only
Two days on either, about 10 hours more on the DELTA Pro Ultra. Android Authority’s author ran his essentials for three to five days on a 5000 Plus.
Two big motors starting together
Only the 5000 Plus has that much surge. Staggering the starts, for example with a soft starter on the AC, lets both handle it.
Recharging from a 240V outlet
The DELTA Pro Ultra takes 3,000W from a 240V outlet; the 5000 Plus takes 240V only through its Smart Transfer Switch, and about 3.5 h from a 120V outlet.
A garage at 20°F in January
The 5000 Plus discharges down to 5°F but won’t charge below 32°F, and Jackery rates it for indoor use. The DELTA Pro Ultra charges and discharges down to −4°F and is IP54.
Refill from solar, each at its maximum
Close: the DELTA Pro Ultra refills a bigger battery slightly faster, if you have the roof for 5,600W.
Home office through an outage
Both carry more than two workdays. Each has a 0ms online UPS: the 5000 Plus on its four 5-20 outlets up to 3,600W, the DELTA Pro Ultra on three outlets.
Charging an EV at 240V
Both can feed 7,200W at 240V; the 5000 Plus’s 14-50 takes most mobile EV chargers directly, the DELTA Pro Ultra needs an L14-30 adapter.
Installing it
The 5000 Plus moves as one heavy box; the DELTA Pro Ultra comes in two stackable pieces, each easier to handle but heavier together.

5000 Plus
DELTA Pro Ultra
Practical consequence: the same four 20A outlets and an L14-30 on both. The 5000 Plus adds a NEMA 14-50 for EV chargers and 50A RV cords; the DELTA Pro Ultra adds a TT-30, a 6-20R and a 30A 12V output.
09 · NoiseNoise: 5000 Plus vs Pro Ultra
On paper the EcoFlow DELTA Pro Ultra (1 battery) is the quieter one: EcoFlow says it runs fanless, at 0dB, under 2,000W for up to 30 minutes, and Yahoo Tech never heard a fan during whole-home outage tests. Jackery rates the Jackery Explorer 5000 Plus at 30dB in Quiet Mode and 51.7dB at full load, both at 1 m.
These are brand figures. We found no independent dB measurement for either.Every figure we found, with its source
What reviewers heard: Quiet charging, at about 1,400W, noticeably cuts fan noise (Gear Diary).
What reviewers heard: Never heard a fan during whole-home outage tests (Yahoo Tech); silent running under a 2,000W load (Trusted Reviews, UK unit); very quiet after a month (SlashGear).
Measured by a tester Brand figure
- Both usually live in a garage or utility room; the noise ratings matter most if yours sits next to a bedroom wall.
Cold and heat: 5000 Plus vs Pro Ultra
The EcoFlow DELTA Pro Ultra (1 battery) is rated for garages and covered outdoor spots: IP54, charging and running down to −4°F. The Jackery Explorer 5000 Plus stops charging at freezing, runs down to 5°F at up to 3,600W below 14°F, and Jackery rates it for indoor use only.
Figures from the Jackery US 5000 Plus page and manual and the EcoFlow US DELTA Pro Ultra page.5000 Plus: output limited to 3,600W below 14°F.
- Keep the 5000 Plus indoors: Jackery rates it for indoor use only, and it doesn’t charge below 32°F.
- For a garage or covered outdoor spot, the DELTA Pro Ultra is the one: IP54, and it charges down to −4°F.
App, UPS and smart features
Close on features. The Jackery Explorer 5000 Plus has the larger 0ms online UPS, four outlets up to 3,600W; the EcoFlow DELTA Pro Ultra (1 battery) adds 4G and generator auto start.
Both switch in under 20ms by default, and both pair with a home transfer switch or panel.Green zone: a switch under about 16ms, which most desktop PCs ride through without restarting.
Can it start a generator by itself? The EcoFlow DELTA Pro Ultra can start and stop a generator on its own; Jackery lists no such feature for the 5000 Plus.
Does it work as a UPS? Both switch in under 20ms by default. The Jackery Explorer 5000 Plus’s Online UPS mode gives 0ms on its four 5-20 outlets, up to 3,600W, though Gear Diary reports losing roughly 15 to 25% of the energy in that mode. The EcoFlow DELTA Pro Ultra’s online UPS covers three outlets.
Does it connect to a home panel? The Jackery Explorer 5000 Plus pairs with Jackery’s Smart Transfer Switch, up to 12 circuits at 120V or 6 at 240V. The EcoFlow DELTA Pro Ultra pairs with the Smart Home Panel 2; SlashGear found it took about four seconds to take over house circuits through the panel.
Can you add a battery later? The Jackery Explorer 5000 Plus takes up to five Battery Pack 5000 Plus, about 30kWh (60kWh with two units through the switch); the EcoFlow DELTA Pro Ultra takes up to five 6,144Wh batteries per inverter, 30.7kWh (90kWh with three inverters).
Can it charge off-peak? Both can schedule charging: a charge and discharge schedule in the Jackery app, self-powered and TOU modes in the EcoFlow app.
How does the app connect? The Jackery Explorer 5000 Plus connects over 2.4GHz Wi-Fi and Bluetooth; the EcoFlow DELTA Pro Ultra adds 4G.
Warranty and support
Both carry 5 years. Jackery covers the Jackery Explorer 5000 Plus for 5 years when bought from Jackery.com, with an optional paid 2-year extension; EcoFlow covers the EcoFlow DELTA Pro Ultra (1 battery)‘s inverter and battery for 5 years each, with no registration condition.
Jackery’s manual also covers authorized dealers; its product page says Jackery.com only. Buying direct is the safe reading.Subject to each brand’s warranty terms and eligibility.
Jackery rates the 5000 Plus at 4,000 cycles to 70% capacity; EcoFlow rates the DELTA Pro Ultra at 3,500 cycles to 80%. The two figures use different end points, so neither is clearly longer-lived on paper.
- Buy the 5000 Plus from Jackery.com and keep the receipt: the product page ties the 5-year warranty to Jackery.com purchases, and it is not transferable.
- Charge the 5000 Plus fully within 7 days of purchase and at least every 6 months: Jackery’s policy excludes the cell otherwise.
What reviewers report
We have not lab-tested these two units. Independent hands-on reviews of the Explorer 5000 Plus are scarce: we found two we could verify, Gear Diary and an Android Authority roundup entry based on the author’s own use, so most 5000 Plus figures on this page come from Jackery’s US documentation. The DELTA Pro Ultra side draws on five published tests. Each point gives the source, author and date; UK and EU units are flagged, since their charge times and outlets differ from US units.
