  "summary": "2,048 Wh LiFePO4 power station with 2,400 W continuous AC output (4,800 W surge) across six outlets, 1,800 W X-Stream charging, up to 1,000 W dual-port solar input, and expansion to 6,144 Wh — at 23 kg.",
  "description": "The DELTA 2 Max (model EFD350) is EcoFlow's upper-mid unit: a 2,048 Wh LFP pack rated for 3,000 cycles to 80%, six AC outlets sharing 2,400 W continuous pure sine output (4,800 W surge), and X-Boost allowing up to 3,400 W for compatible resistive loads. Wall charging accepts 1,800 W; EcoFlow publishes only partial recharge claims ('80% in 1.1 hours'), so the full AC recharge time is honestly null here. Dual solar ports take 500 W each for 1,000 W combined at 11–60 V. The page markets a '<20 ms UPS Auto-Switch' while the manual describes EPS bypass with ~30 ms switchover — recorded as marketed-UPS with the switchover-time conflict preserved. Two Smart Extra Batteries take the system to 6,144 Wh.",
