Overview
The DELTA 3 Plus (EF-DL-H10-4) is the step up from the DELTA 3: the same 1,024 Wh LFP capacity and 1,800 W output on six AC outlets, but with 140 W USB-C ports and two 500 W solar inputs for 1,000 W of solar charging. EcoFlow states a 56-minute full charge at 1,500 W AC, 4,000 cycles to 80% capacity, a UPS switchover under 10 ms and a 5-year warranty. It accepts DELTA 3, DELTA 2, DELTA 2 Max and DELTA Pro 3 extra batteries for up to 5 kWh. X-Boost (up to 2,600 W for resistive loads) is not counted as continuous output.
Variant note: DELTA 3 Plus (EF-DL-H10-4), standalone. Distinct from the DELTA 3 (EF-DL-H10-3) and DELTA 3 Classic (EF-DL3-C), both indexed separately, and from the DELTA 3 Max Plus and Ultra Plus.
Data note: Core specs from EcoFlow's US product page; capacity, chemistry and expansion from the Amazon listing, which also agrees on 1800 W, 1500 W AC input, 1000 W solar and 13 total outlets. Weight 12.5 kg (27.6 lb) and 398 x 202 x 283.6 mm from EcoFlow; Amazon shows 27 lb and 16 x 8 x 11 in. Full charge 56 minutes from EcoFlow's feature description (the Amazon bullet ties 56 minutes to the Smart Generator path), so confidence is medium. maxExpandableCapacityWh is an 'up to' marketing maximum.

Comparisons featuring this product
Current 1 kWh Models: EcoFlow DELTA 3 vs DELTA 3 Classic vs DELTA 3 Plus vs OUPES Mega 1 vs BLUETTI Elite 100 mini
Five current-generation 1 kWh LiFePO4 stations sold on Amazon. Four share roughly the same 1,024 Wh pack, so they separate on output (700–2,000 W), solar input (350–1,000 W), charging speed, expansion, and footprint (10.7–12.6 kg).
