These are not peers on paper. The Jackery is a sealed ~2 kWh pack with a 2200 W inverter. The DELTA 2 is a ~1 kWh pack that can grow with extra batteries. Shoppers still pair them because both sit in the “keep the fridge and the router up” budget.

How to read the mismatch
Watt-hours decide how long a 60 W load runs. Inverter watts decide whether a microwave or a fridge compressor is even allowed to start. The Jackery lists 2042 Wh and 2200 W rated. The EcoFlow lists 1024 Wh and 1800 W (2700 W surge). That is roughly double the energy in the Jackery, at a higher rated AC output, at a higher weight (39.5 lb vs 27 lb).
The EcoFlow’s answer is expansion: add a DELTA 2 extra battery and EcoFlow’s own pages say you reach 2048 Wh — almost the Jackery’s energy, in two boxes. That is a different product shape (more dollars, more weight, more cables) even if the headline kilowatt-hours converge.
Solar and recharge
Jackery lists 400 W max solar on two DC8020 ports. EcoFlow lists 500 W (11–60 V, 15 A). If your plan is “two 200 W folding panels,” both can ingest that class of array; the EcoFlow has 100 W more headroom on the spec sheet. Jackery quotes ~1.75 hours on AC; EcoFlow markets X-Stream up to 1200 W. We did not time either unit.
Who each spec sheet fits
- Jackery 2000 v2 — one-piece 2 kWh, 2200 W, not expandable, UPS <20 ms in Jackery copy, indoor-quiet claim <30 dB.
- DELTA 2 — lighter to carry today, expandable tomorrow, 13 ports in EcoFlow marketing, 5-year warranty copy on regional EcoFlow storefronts.

X-Boost ceiling is 2200 W on some regional storefronts and 2400 W on some EU pages — regional firmware/copy conflict; we flag it instead of picking a favorite.
