EcoFlow DELTA 2 vs Jackery Explorer 1000 Plus

Two of the best-selling solar generators in the 1,000 Wh class — both LFP, both expandable, both silent. The real differences are in surge power, charge speed, and how long they last under load.

Note: Unlike gas generators, the binding constraint here is Wh capacity (runtime) and inverter surge (what it can start). Our model addresses both.

Runtime Model: How Long Does Each Unit Last?

Calculated at 85% inverter efficiency (industry standard). Formula: runtime = usable Wh ÷ load watts. EcoFlow usable capacity: 870 Wh. Jackery usable: 1,074 Wh.

Load	EcoFlow DELTA 2	Jackery 1000 Plus
CPAP Machine 60 W running — Both power a CPAP for multiple nights	14.5 hrs	17.9 hrs
Phone + Laptop + Lights 170 W running	5.1 hrs	6.3 hrs
Mini Fridge (60W avg) 60 W running	14.5 hrs	17.9 hrs
Refrigerator (700W running) 700 W running — Enough for a short outage — not overnight	1.2 hrs	1.5 hrs
Window AC 10,000 BTU (1,200W) 1200 W running — Runtime under 1 hr — solar generators aren't AC units	0.7 hrs	0.9 hrs

Surge Power Verdict: What Each Unit Can Start

Runtime tells you how long. Surge tells you whether. A battery unit with insufficient peak output will trip its inverter instead of starting the load.

Scenario A — Medical / Camping Essentials

CPAP (60 W) + Phone charging (20 W) + LED lights (30 W) = 110 W running / 110 W starting
EcoFlow runtime: 7.9 hrs — Jackery runtime: 9.8 hrs

EcoFlow: ✓ one full nightJackery: ✓ nearly two nights

For CPAP-dependent users, Jackery's extra 240 Wh is a meaningful safety buffer for multi-night outages.

Scenario B — Sump Pump ½ HP During Storm Outage

Sump Pump ½ HP: 800 W running / 2,300 W starting surge

EcoFlow: ⚠ 2,700 W surge > 2,300 W — passes, but tightJackery: ✓ 4,000 W surge — handles it with 1,700 W headroom

EcoFlow technically passes, but at 85% of its peak surge — repeated sump pump cycling under load risks inverter trips. Jackery's 4,000 W surge is definitively more reliable for motor loads.

Scenario C — RV Air Conditioner 13,500 BTU (the decisive test)

A standard RV roof AC needs 1,700 W running / 3,300 W starting. This is where the 4,000 W vs 2,700 W surge gap becomes a pass/fail line.

Unit	Surge Output	RV AC Needs	Can Start?	Runtime if Started
EcoFlow DELTA 2	2,700 W	3,300 W	✗ NO	—
Jackery 1000 Plus	4,000 W	3,300 W	✓ YES	~38 min

Model verdict: The Jackery 1000 Plus can start a 13,500 BTU RV AC; the EcoFlow DELTA 2 cannot — its 2,700 W peak surge falls 600 W short of the 3,300 W startup requirement. However, even with Jackery, runtime is only ~38 minutes before the battery is exhausted. For sustained AC operation you need a gas generator (3,300 W+) or the EcoFlow DELTA Pro (3,600 Wh, 3,600 W continuous). Use our calculator to check your full load.

Scenario D — Hair Dryer or Space Heater via X-Boost

A typical hair dryer draws 1,875 W — above DELTA 2's 1,800 W continuous rating but within X-Boost range (up to 2,200 W)

EcoFlow: ✓ X-Boost handles it (runtime ~28 min)Jackery: ✗ trips at 2,000 W continuous — no X-Boost

X-Boost is EcoFlow's unique advantage for resistive loads like hair dryers and travel kettles that exceed the rated continuous output.

Bottom Line

Choose EcoFlow DELTA 2 if…

You prioritize fast recharging (1.5 hrs AC / solar)
You need 6 AC outlets for multi-device setups
X-Boost for hair dryers / kettles matters
Lighter weight (27 lbs) is important for travel

Choose Jackery 1000 Plus if…

You need to start a sump pump or RV AC
Longer runtime matters (24% more capacity)
You want 4,000+ battery cycles (longer lifespan)
Multi-night CPAP backup is a safety requirement

Need sustained AC power or whole-fridge overnight backup? Neither unit is enough.

At 1,000–1,264 Wh, both units are firmly in the camping and micro-outage category. Running a full-size refrigerator for 12+ hours requires 3,000+ Wh. The EcoFlow DELTA Pro (3,600 Wh, 3,600 W continuous, 7,200 W surge) is the next logical step — and it can actually sustain RV AC for over an hour per charge, or power a fridge through the night.
