EcoFlow DELTA ProvsJackery HomePower 3600 Plus (2026)

• You have to move this thing between rooms, pull it to a campsite, or lift it into a truck or RV, and you need it to charge in freezing weather.
• The Jackery weighs 77.16 lb vs the DELTA Pro’s 99 lb — a 22 lb gap that is decisive when you have to maneuver it. Our review confirms the lived experience: testers pulled it like carry-on luggage and the wheels worked on concrete, gravel, and snow.
• It charges and discharges from −4 °F to 113 °F. Our review documents it running a full camper — AC compressor, microwave, fridge, lights — at ~1,600 W sustained, and powering an off-grid RV for ~18 hr on fridge, furnace, lights, and occasional microwave.
• It carries a true 30 A NEMA TT-30 RV outlet that delivers the full 30 A continuous, plus a confirmed 10 ms UPS for flicker-free transfer at the campsite.
• The DELTA Pro weighs 99 lb, and our review repeats the weight complaint across every source type. Just as important, our review is silent on cold-weather charging — there is no documented sub-freezing charge behavior in the record, so for a cold deployment it cannot be credited with a capability the Jackery proves.
• One catch: the Jackery has no 12 V DC output. A 12 V camping fridge or accessory cannot run directly off it — you will need to run that load on AC through an adapter, or route it to a unit that has 12 V DC ports.

• You need stationary insurance. The unit lives in a closet or garage, holds charge for months, and earns its keep a few times a year running the fridge, freezer, router, lights, and maybe a medical device through an outage.
• The DELTA Pro is the cheaper unit at $1,599 vs $1,899, and delivers better value at $0.444 per Wh vs $0.53 per Wh — roughly a 16% lower price for effectively the same usable energy.
• At an essentials 120 V AC regime (roughly 150–600 W), the DELTA Pro measures approximately 3,200–3,290 Wh usable and the Jackery measures approximately 3,240–3,270 Wh. Compared at the same regime they are inside each other’s margin, so the price gap is real value.
• Standby retention is quantified and strong: our review reports owners seeing 99–100% charge after a year sitting idle — exactly the behavior an emergency unit needs.
• While grid-connected, the DELTA Pro’s pass-through ceiling (roughly 1,800–2,200 W) is higher than the Jackery’s bypass cap (roughly 1,440 W), so more of your essentials run without dropping to battery.
• The Jackery is the more expensive box for the same job on the governing price, and its standby retention, while good, is less specifically documented.

• You are backing up electronics that cannot tolerate even a brief blink — a desktop mid-write, a NAS, a network rack, a monitoring or medical device that must not reset. You need a documented sub-cycle switchover.
• The Jackery is UPS-capable with a confirmed 10 ms switchover. 10 ms is fast enough to ride through for most computer power supplies and network gear.
• The honest limit, stated up front: in bypass mode the Jackery’s output through the outlets is capped at roughly 1,440 W, not the full 3,600 W. For this segment that is usually fine — desktops, NAS, networking, and small medical electronics sit well under 1,440 W — but keep the UPS-protected load light and do not expect to start heavy motors through the wall.
• The DELTA Pro’s UPS status is unknown — no switchover time is published in the record. For a buyer whose entire requirement is a proven sub-cycle transfer, an unconfirmed number cannot win against the Jackery’s confirmed 10 ms.

• You run revenue equipment off this — a heat press, dual freezers on a vending truck, a car-wash setup, power tools — often for a full day, sometimes with 12 V accessories in the mix.
• Our review confirms this use case directly: owners run heat presses, dual freezers on an ice-cream truck, and car-wash setups for multiple-day runtime with zero voltage drop under sustained draw. Bench testing backs it: a clean pure-sine 2,900 W sustained and 4,000 W held for over three minutes before a controlled shutdown.
• It has the ports for mixed mobile rigs: 5 AC outlets plus the 30 A TT-30, plus genuine 12 V DC output via car port (126 W) and Anderson port (12.6 V / 30 A) that the Jackery lacks entirely. For a vendor running 12 V coolers or lighting alongside AC tools, that is a real functional gap on the Jackery.
• It is the cheaper unit on canonical price at $1,599 vs $1,899, which matters for a tool that is a business cost.
• The Jackery is genuinely strong here — our review measured roughly 3,200 W stacked kitchen loads clean and roughly 4,700 W combined held without tripping, marginally higher measured overload tolerance than the DELTA Pro’s bench figure, and its 30 A TT-30 delivers full 30 A continuous. It loses the segment on two points: our review frames and validates it as an outage and RV unit rather than a vendor workhorse, and it has no 12 V DC output.
• Critical caveat on the DELTA Pro: the full 3,600 W is only available off battery. Plugged into a standard wall outlet, output throttles to roughly 1,800–2,200 W and high-surge starts will trip an overload. For vendor work, run it off battery and recharge between sessions, not in pass-through.

Attended off-grid with a real solar array (you are there to manage it):

• Pick the EcoFlow DELTA Pro. It has the materially better solar front end: 1,600 W max input across an 11–150 V range vs the Jackery’s 1,000 W, 60 V-ceiling, parallel-only input. The DELTA Pro’s wide voltage window accepts higher-voltage series strings, which lets you build a faster array.
• The Jackery’s 60 V ceiling forces parallel-only and its two solar ports share one controller, so mismatched third-party panels risk driving overcurrent into the lower-spec port — a hardware-damage path documented in our review.
• Both reviews are blunt that bundled portable panels are too slow (DELTA Pro: up to roughly 3 days for the 400 W folding panel; Jackery: 10+ hr for a 2× 200 W pair), so plan rigid, roof-mounted wattage either way.

Unattended, set-and-forget off-grid (a cabin no one visits for stretches):

• Lean Jackery HomePower 3600 Plus, with eyes open. This is the one place the DELTA Pro draws a hard veto: its inverter does not auto-restart after a low-battery shutdown. If it depletes while you are away, solar alone will not bring the AC outputs back, and the DC outputs lack an always-on restore. Our review calls this disqualifying for unattended off-grid.
• The Jackery carries no documented auto-restart failure, so for a truly unattended site it is the safer of the two — but its undersized 1,000 W solar input and the connector-mismatch risk mean it is a compromise, not a clean win.
• If unattended off-grid is your primary use, the honest reading is that both of these are the wrong tool, and a unit built for self-sustaining cycling is the better spend.
