EcoFlow DELTA 3 Classic Portable Power Station, 1024Wh 1800W

- 1024Wh, 1800W (3600W X-Boost surge)
- 45-min 0-80% X-Stream charge
- <10ms UPS switchover
Our take
Under-10ms UPS switchover protects PCs and medical devices from data loss during outages, and LiFePO4 cells rated for 10+ years pair with EV-grade CTC design for durability.
Why it made the shortlist
X-Stream AC charging hits 0-80% in a genuine 45 minutes.
A 500W solar panel (sold separately) recharges the unit in 2.5 hours, and the EcoFlow app adds Storm Alert and Self-Powered Mode for proactive outage prep.
What works
- X-Boost expands rated output to a genuine 2600W continuous
- 45-minute 0-80% charge is genuinely fast via X-Stream
- Storm Alert mode proactively preps for incoming outages
Watch out for
- Not compatible with DELTA 2 or Delta 3 Smart Extra Batteries
- Solar panel for the 2.5-hour charge is sold separately
- The catch
- X-Boost technology pushes rated 1800W output to a documented 3600W surge, expandable to 2600W continuous with X-Boost for heavier loads like refrigerators and microwaves.
