one side unscoredWhat EcoFlow DELTA 3 Classic and Jackery Explorer 1000 v2 owners report
Independent sources, scored for each model. DELTA 3 Classic on 5 of five, Explorer 1000 v2 on 5.
Both readings are about these exact models.
What they say
EcoFlow DELTA 3 Classic
- Five owner reports on the DELTA 3 Classic appear in r/Ecoflow_community between November 2025 and July 2026.
- Two owners describe it running network gear through outages without trouble for months (May 2026).
- One owner's AC output switched itself off at 4 a.m. in UPS use and took down a server, blaming buggy schedules (June 2026), another heard an inverter whine (March 2026), and a July 2026 buyer was surprised to find no 12 V socket.
Jackery Explorer 1000 v2
- Owner reports on the Explorer 1000 v2 are mostly positive: about nine owners on r/Jackery and r/SolarDIY describe it running a CPAP overnight, outages and daily solar use without trouble.
- One owner ran a CPAP for about 10 hours on DC with 42 percent left and found the fan noise acceptable (March 2026).
- Against that, a brand-new unit's relay stuck on with a burning smell and was being replaced (May 2026), and owners fault the proprietary solar ports and the app's limited battery settings.
Both readings are about these exact models.
What they say
EcoFlow DELTA 3 Classic
- TheSolarLab, which earns affiliate commission on EcoFlow links, measured 83 percent inverter efficiency, a full charge in just under 55 minutes and about 17 W of idle draw, and faulted its few outlets, the missing 12 V socket and the 500 W solar cap.
- VanTour tested it at EcoFlow's request with a promotional code (March 2026) and first saw only 500 W of wall input.
Jackery Explorer 1000 v2
- Four written reviews test the 1000 v2.
- OutdoorGearLab, which buys its test units, drew 910 Wh on AC, 85 percent of rated, charged it in 1.58 hours and ranked it seventh of 14 (July 2026).
- TheSolarLab, which carries Jackery discount codes, found it 87.5 percent efficient at a 1,479 W load and faulted Jackery's page for listing more solar input than the 400 W it accepts.
- Business Insider, which earns affiliate commission, measured about 90 percent with a plug-in meter and named it best overall (July 2026); New Atlas tested it at Jackery's request.
