On a sunny driveway the DELTA 3800 Gen4 wins; in a freezing garage the HomePower 3600 Plus does.
The EcoFlow DELTA 3800 Gen4 and the Jackery HomePower 3600 Plus both deliver 3,600W, surge to 7,200W and carry 6,000 cycles to 70%, and only 179Wh separates them. The EcoFlow doubles the solar input to 2,000W and weighs 67.5 lb, but it needs two hands and stops charging at 32°F. The Jackery rolls on wheels at 77.16 lb, charges down to −4°F, grows to about 21.5kWh and reaches 240V with a second unit.
Below: the five gaps that matter, a 20-second calculator, eight situations picked for this pair, and what PCMag measured on the HomePower 3600 Plus. As of November 5, 2026, no full independent review of the DELTA 3800 Gen4 had been published.
Prices $200 apart today. Output, surge and cycle life match, and neither has a 12V socket. Decide by climate and by plans: the 3800 Gen4 favors sun and a lighter lift, the 3600 Plus favors cold storage, wheels and a much higher ceiling.
- you have roof or yard for panels
- 10 lb less beats wheels
- you own a Smart Generator
- you charge below freezing
- you roll it around
- you may need 240V later
The five differences that decide it
What matches: 120V, 3,600W, a 7,200W surge, a 30A outlet, 6,000 cycles to 70%, about the same wall-charging time and 3 plus 2 years of warranty. These five don’t.

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 3,199Wh usable on the 3800 Gen4 and 3,046Wh on the HomePower 3600 Plus. PCMag got about 3,240Wh out of the Jackery, a bit better than our 85% rule.
Appliance for appliance, the 3800 Gen4 lasts 5% longer than the HomePower 3600 Plus.

The price gap, in numbers
The EcoFlow DELTA 3800 Gen4 costs $200 less than the Jackery HomePower 3600 Plus and still holds 179Wh more.
Prices refresh daily from EcoFlow US and Jackery US.Cycle ratings match, 6,000 to 70%, so a lifetime card would just repeat the first one. The second card shows what a first battery really adds: 2,048Wh on one side and 3,584Wh on the other. Two batteries on the EcoFlow also need its Expansion Adapter; 240V on the Jackery needs a second unit and the Jackery Connector.
Eight modeled situations, worked out
Same formula as the calculator above: 85% of rated capacity, and panels at 70% of their rating. Extra batteries appear only where stated.
Refilling from a full array
This is the EcoFlow’s strongest case. Winter sun often leaves only a few good hours, and 2,000W of panels can fill it inside that window. It takes two strings on 11 to 60V inputs, so check your panels’ voltage.
January in an unheated garage
Jackery rates charging and discharging from −4°F to 113°F. EcoFlow stops output at 14°F and charging at 32°F, so a cold 3800 Gen4 comes indoors first.
A 240V well pump
Two HomePower 3600 Plus units reach 240V and 7,200W through a Jackery Connector, sold separately. Linked that way, they charge from solar only. EcoFlow lists no 240V route for the DELTA 3800 Gen4.
Three steps up from the driveway
Steps favor the EcoFlow, flat floors favor the Jackery. If you’d roll it most days, budget for EcoFlow’s folding cart.
Two days on the essentials
Alone they land an hour apart, just short of a day. With one battery each, the Jackery’s bigger pack is the only one that clears 40 hours.
Topping up from a generator
EcoFlow’s Smart Generator 4000 feeds up to 3,200W through the battery port and can start and stop itself. PCMag refilled the Jackery in under two hours from a 3,500W generator, and had to lower the charge rate once when maximum AC input shut the inverter off.
PC and router on UPS
Switching speed is effectively a tie. The practical gap is load: Jackery caps UPS mode at 1,440W. EcoFlow publishes no such cap but has no HID link, so a PC won’t shut down on its own.
Just the refrigerator
Two days and a bit on either. EcoFlow’s 70+ hours comes from its own run with an empty fridge averaging about 53W and Fridge Runtime Boost on, with no other AC load, so don’t compare it with Jackery’s blank.
Nine more differences, the spec sheet and the box

Every port, side by side
DELTA 3800 Gen4
HomePower 3600 Plus
In daily use the outlets look alike: four 20A plus a 30A, and no 12V socket on either. The Jackery’s four share 2,400W. The EcoFlow adds a third USB-C, though its 65W ports fall to 16W when they share a circuit with USB-A.
08 · NoiseNoise: 3800 Gen4 vs HomePower 3600 Plus
The brand figures match at full power: up to 50dB for the EcoFlow DELTA 3800 Gen4, 50.3dB for the Jackery HomePower 3600 Plus. PCMag heard the Jackery at 55 to 60dB from 3 ft under 3,400W.

App, UPS and smart features
The Jackery HomePower 3600 Plus scales further and reaches 240V in pairs. The EcoFlow DELTA 3800 Gen4 starts a Smart Generator on its own and recharges before storms.
Neither lists a home panel for this model.Green zone: a switch under about 16ms, which most desktop PCs ride through without restarting.
Can it deliver 240V? Two Jackery HomePower 3600 Plus units and the Jackery Connector deliver 240V and 7,200W. The EcoFlow DELTA 3800 Gen4 stays at 120V.
Can it start a generator by itself? The EcoFlow DELTA 3800 Gen4 starts and stops a compatible EcoFlow generator through its extra battery port, not through AC charging. Jackery lists nothing similar for the Jackery HomePower 3600 Plus.
Does it prepare for storms? Storm Guard 2.0 on the EcoFlow DELTA 3800 Gen4 recharges ahead of severe weather. We found nothing equivalent on the Jackery HomePower 3600 Plus.
Does it have a quiet charging mode? Jackery rates Quiet Mode on the Jackery HomePower 3600 Plus at 30dB at 1 m. The EcoFlow DELTA 3800 Gen4’s US page lists no quiet mode.
Can you add a battery later? The EcoFlow DELTA 3800 Gen4 takes two extra batteries, 2,048Wh or 4,096Wh each. The Jackery HomePower 3600 Plus takes five Battery Pack 3600 at 3,584Wh each.
Does it work as a UPS? Both switch in about 10ms. The Jackery HomePower 3600 Plus limits UPS mode to 1,440W. The EcoFlow DELTA 3800 Gen4 can’t tell a PC to shut down.
Warranty and support

UPS and output
Practical limits before you buy
- Stock moved on launch week. On November 5, 2026, Jackery US showed the HomePower 3600 Plus alone as sold out, while its kits with a Battery Pack 3600 or solar panels were still listed. The badge at the top of this page updates by itself.
- EcoFlow’s 12kWh needs a battery you may not get yet. The DELTA Pro 3 Extra Battery showed unavailable on November 5, 2026; with two 2,048Wh batteries the total is 7,859Wh.
- Neither has a 12V socket. A car cooler needs an AC adapter on both.
- A paired Jackery charges from solar only. Plan refills before you link two units for 240V.
- 2,000W of solar means two ports. Each takes 1,000W, 11 to 60V and 20A; high-voltage strings won’t fit.
- No automatic start without a battery port connection. AC generator charging on the EcoFlow stays manual, at 1,800W.
- The 70+ hour fridge line is EcoFlow’s lab case. It used an empty fridge and one appliance.
- Jackery’s UPS mode stops at 1,440W. Put only the essentials on it.
Frequently asked questions
What separates the DELTA 3800 Gen4 from the HomePower 3600 Plus?
