PowerMax 1800 SE Power Station

PowerMax 1800SE (entry in the high-output range):

• Key Specs

  • Battery Capacity: 1024Wh (LiFePO4 cells for safety/longevity — 3,500+ cycles to 80% capacity, up to ~10+ years with proper care).
  • Output Power: 1800W continuous (rated), 3600W surge/peak — handles most household appliances (fridge, microwave, coffee maker, power tools, lights, laptops, etc.) without overload in most cases.
  • Inverter: Pure sine wave (clean, safe power for sensitive electronics like medical devices or TVs).
  • Ports/Outputs:
    • 3 × AC outlets (1800W max each/total).
    • 2 × USB-C (100W PD max each — great for fast laptop/phone charging).
    • USB-A ports (15W + 18W).
    • Likely DC outputs (car port, etc.) and wireless charging in some variants.
  • Charging:
    • AC input: Up to 800W (0-80% in ~1 hour; full in ~1.5-2 hours).
    • Solar input: Up to 800W (fast solar recharge — pairs excellently with one or two PM400 panels for ~400-800W solar input in good Calgary sun).
    • Other: Car charging support.
  • Features:
    • Expandable? Some listings mention scalability (e.g., to 2048Wh with extra battery pack), but core model is 1024Wh standalone.
    • App control (Bluetooth/Wi-Fi for monitoring, scheduling, remote on/off).
    • UPS mode (fast switchover ~8-10ms for seamless backup during outages).
    • Lightweight & portable: ~15.5 kg (34 lbs) — much lighter than similar-capacity competitors (e.g., 25% smaller/lighter claims).
    • BMS safety system, IP-rated elements for outdoor durability.
  • Dimensions/Weight: Compact briefcase-style (exact dims vary but portable with handles).

  This model is positioned as a "lighter body, wilder power" option—great mid-range choice between smaller units and beasts like the PowerMax 6000.

• 5 years warranty.
