Overview

The DELTA 2 is EcoFlow's benchmark 1 kWh unit: a 1,024 Wh LFP pack rated for 3,000 cycles to 80%+, six AC outlets sharing 1,800 W continuous (2,700 W surge), and X-Boost — a boost mode that lets resistive loads up to 2,200 W run, distinct from the continuous rating and unavailable in bypass mode. X-Stream wall charging pulls up to 1,200 W for an official 80-minute full recharge, with 0–80% claimed in 50 minutes. Solar input accepts 500 W (11–60 V). The manual documents EPS with ~30 ms switchover ('does not support 0ms switching'), and EcoFlow consistently markets it as EPS rather than UPS. One DELTA 2 or DELTA 2 Max extra battery expands the system, with the current page citing up to 3,072 Wh.

Variant note: Standalone DELTA 2. DELTA 2 Max is a separate larger model (2,048 Wh), not a variant. Solar-generator bundles excluded.

Data note: X-Boost ('Max Device(s) Power (with X-Boost) 2200W') is a boost mode, never counted as continuous; manual notes it is unavailable in bypass mode. Expansion maximum stated as 3,072 Wh on the current page while the older DELTA Max pairing was historically marketed as 3,040 Wh — both official texts recorded, current page value used. Minor inch-dimension discrepancy (page 11 in vs manual 11.1 in third dimension); mm values identical in both sources. MPPT not mentioned in any official source checked — left null. Retail-status check 2026-08-02: the EcoFlow US storefront URL (us.ecoflow.com/products/delta-2-portable-power-station), which was this record's officialProductUrl and is still cited by several provenance entries, now returns a 301 to the DELTA 3 product page. The brand-site page (www.ecoflow.com/us/delta-2-portable-power-station) is still live and self-canonical, still titled 'New EcoFlow DELTA 2', and is now this record's officialProductUrl. That page carries no purchase link for the DELTA 2 itself, only cross-sell links to DELTA 3, DELTA 2 Max and other current models. EcoFlow has published no discontinuation statement, so releaseStatus is 'unclear' rather than 'discontinued': the unit is evidently no longer sold direct by EcoFlow US, but that is an inference from a redirect, not an official claim. The provenance sourceUrl values were deliberately left pointing at the storefront URL, since they record where each quote was read on 2026-07-04 and rewriting them would misstate the provenance. Headline figures re-confirmed against the live brand-site page on 2026-08-02 (1,024 Wh, 1,800 W, 2,700 W surge, 2,200 W X-Boost, 3,072 Wh expansion, 500 W solar, 3,000 cycles, LFP); sourceLastChecked is NOT advanced because weight, dimensions, outlet count and AC input were not re-verified.

Use cases

Home backup with expansion path to 3,072 Wh
Most household appliances under 1,800 W continuous (resistive loads to 2,200 W via X-Boost)
Router/computer backup via ~30 ms EPS switchover
Off-grid and vanlife charging with 500 W solar input

Strengths and weaknesses

Strengths

80-minute official full recharge at 1,200 W X-Stream input
Six AC outlets — most in the 1 kWh class here
3,000-cycle LFP rating with expansion battery support
Honest EPS positioning: EcoFlow's own docs distinguish it from a UPS
5-year warranty

Weaknesses

EPS switchover (~30 ms) is slower than several rivals' stated figures
X-Boost 2,200 W applies to resistive loads only and not in bypass mode
USB-C limited to 200 W total across two ports
Expansion maximum is stated inconsistently across official EcoFlow texts (3,072 vs historical 3,040 Wh)

Use-case fit

Recommended for: Camping Portable Power (#1) · CPAP Backup Portable Power (#2)

Also eligible for: RV Portable Power · Apartment Outage Backup · Home Office Backup · Vanlife Portable Power

Fit is computed from this product's normalized fields using each use-case page's published hard filters and ranking rules — see any linked page for the exact logic.

Comparisons featuring this product

1 kWh Class: EcoFlow DELTA 2 vs BLUETTI AC180 vs Jackery Explorer 1000 v2 vs Anker SOLIX C1000 vs Pecron E1000LFP

Five US-market 1 kWh-class LiFePO4 stations compared on official specs. All but the Explorer 1000 v2 deliver 1,800 W continuous; they diverge sharply on weight (10.8–16 kg), solar input (400–600 W), expansion (none to 4,864 Wh), and recharge behavior.

Merchant	Price	Checked	Availability	Link
EcoFlowprimaryManufacturer direct	Not tracked	—	—	View at EcoFlow
AmazonaffiliateMarketplace	Not tracked	—	—	View at Amazon — Search URL, not a product link: the candidate ASIN B0B9XB57XM is titled DELTA 2 in search results but its live page resolves to a DELTA 3 (Model Name DELTA 3). No listing verified as the DELTA 2 was found. This corroborates the withdrawal recorded in notes, where EcoFlow US also 301-redirects the DELTA 2 storefront URL to the DELTA 3. Do not upgrade on a near-match.
