Compare the standalone US packages: expansion support, normal AC output, solar-input limits and what the battery claims mean.
The decision in brief
How the options differ
Start with the load you need to power. DELTA 3 Plus has a higher normal AC output and a documented extra-battery path. Explorer 1000 v2 has slightly more rated energy in a lighter fixed-capacity unit. Neither specification alone predicts runtime.

The buying guide
Package and specification details
Capacity and output answer different questions
EcoFlow lists 1024 Wh and 1800 W of normal AC output; Jackery lists 1070 Wh and 1500 W. Watt-hours describe stored energy and watts describe power. Check appliance startup demand separately; surge and boost figures are not the normal output rating.

Expansion changes the purchase plan
The DELTA 3 Plus page names compatible extra batteries and connection equipment. Explorer 1000 v2 does not accept additional battery packs. Check the exact battery and cable pairing before choosing the EcoFlow for expansion.

Solar input is a ceiling, not a charging promise
EcoFlow lists two 500 W inputs; Jackery lists 400 W combined. Panel open-circuit voltage, current, connections, temperature and sunlight still limit a usable system. Neither starting package includes panels.
Review due. Check the current source before buying.
Read the retention endpoint
Both makers claim 4000 cycles, but EcoFlow uses at least 80% retained capacity and Jackery at least 70%. These claims are not equivalent lifespan tests. Unit weights are about 12.5 kg and 10.8 kg respectively, before accessories.

Common questions
Does higher wattage mean longer runtime?
No. Runtime depends on usable energy, the actual load, conversion losses and settings. The AC-output rating chiefly limits which loads the unit can supply.

Evidence limits
These manufacturer specifications do not establish measured performance, noise, long-term reliability or running cost. We have not independently tested these products. Check current prices, stock and operating-space instructions with the seller and manufacturer.

Supports an expansion battery
Whether this exact generation supports a separate capacity expansion battery.

Cycle-life capacity endpoint
Remaining rated capacity used for the cycle-life claim.
A claim measured to 70% capacity is different from one measured to 80%.
