Overview
The DELTA 3 is EcoFlow's current-generation 1 kWh unit (model EF-DL-H10-3): a 1,024 Wh LFP pack rated for 4,000 cycles to 80%+, six AC outlets sharing 1,800 W continuous pure sine output with a 3,600 W surge, and X-Boost for resistive loads (the US page says 2,200 W, the manual's 120 V table says 2,600 W — conflict preserved, and neither counts as continuous). X-Stream charging accepts 1,500 W for an official 0–100% in 56 minutes, and the XT60 input takes 500 W of solar through MPPT. The manual explicitly describes a standby UPS with 10 ms transfer time. Extra-battery support spans four EB models, marketed up to 5 kWh total.
Variant note: Base DELTA 3 (model EF-DL-H10-3), capacity exactly 1,024 Wh per official sources — NOT the 2 kWh class some third-party summaries claim. Distinct from DELTA 3 Plus, DELTA 3 Classic (3+2 y warranty), DELTA 3 1500, DELTA 3 Max, DELTA 3 Max Plus, DELTA 3 Ultra, and DELTA Pro 3, all separate products.
Data note: X-Boost conflict preserved: US page 'Max Device(s) Power (with X-Boost) 2200W' vs manual 120 V row '2600W' (the page's figure matches the manual's 220 V row) — X-Boost never counts as continuous. The page's 'Car Charging 800W, in 1.3 Hour' refers to the separately sold 800 W Alternator Charger; native cigarette-lighter input is 12V⎓8A (~96 W). Manual labels dimensions (W×D×H) 202 × 397.6 × 283.6 mm — same values as the page, different order; page source order recorded. maxExpandableCapacityWh 5,000 is an 'up to' marketing maximum. Availability verified in-stock at $519 at check time. JP variant differs (100 V, 1,500 W); US values recorded.

Use cases
- Home backup for appliances under 1,800 W with a documented 10 ms standby UPS
- Fast-turnaround use: 0–100% in an official 56 minutes
- Expandable backup up to a marketed 5 kWh with EB packs
- Off-grid charging with 500 W MPPT solar
Strengths and weaknesses
Strengths
- Official 56-minute full recharge — fastest in this index's 1 kWh class
- 4,000-cycle LFP rating at the 80% threshold
- Documented standby UPS with 10 ms transfer (not just marketing)
- Six AC outlets with 3,600 W surge
- Cross-compatible with four extra-battery models
Weaknesses
- X-Boost figure conflicts between the US page (2,200 W) and manual 120 V table (2,600 W)
- Native car charging is only ~96 W (the '800 W in 1.3 h' page claim requires the separately sold Alternator Charger)
- DC5521 ports lack a stated wattage
- Crowded DELTA 3 family naming (Plus/Classic/1500/Max/Ultra) invites confusion
