  "summary": "Five current-generation 1 kWh LiFePO4 stations sold on Amazon. Four share roughly the same 1,024 Wh pack, so they separate on output (700–2,000 W), solar input (350–1,000 W), charging speed, expansion, and footprint (10.7–12.6 kg).",
  "verdict": "The three EcoFlow DELTA 3 models share a 1,024 Wh LFP pack, 1,800 W continuous with a 3,600 W surge, six AC outlets and a sub-10 ms UPS, and differ on extras. The DELTA 3 Plus is the most capable: 1,000 W of solar across two inputs, 140 W USB-C, 4,000 cycles to 80% and expansion to 5 kWh. The DELTA 3 has an official 56-minute full charge, 500 W solar and the same expansion. The DELTA 3 Classic drops expansion and some low-voltage ports, charges at 1,400 W (80% in about 45 minutes) and publishes no cycle rating, so it suits buyers who will never add a battery. The OUPES Mega 1 has the strongest inverter here, 2,000 W continuous and 4,500 W surge, with expansion to 5,120 Wh and a claimed 36-minute 0 to 80% charge, but its specs come only from its Amazon listing and it has four AC outlets. The BLUETTI Elite 100 mini is the small-footprint pick: 10.7 kg in an upright case with three AC outlets and 140 W USB-C, but only 700 W continuous and 350 W solar.",
