This is a serious whole-home backup solution, not a portable camping station. The 3500W inverter handles essentials like refrigerators, lights, and HVAC with UPS switching under 20ms so devices don't notice the transition during an outage. Starting capacity is 5.12kWh with LiFePO₄ batteries, expandable up to 15.36kWh by stacking additional modules. The LiFePO₄ chemistry is rated for 3,000+ cycles (8–10 years), operates down to -4°F, and includes a BMS for protection. App monitoring and a wheeled trolley with telescopic handle round it out.
A power station community member called it "the current reigning king of price per Wh for a reputable all-in-one solution" at 21 cents per Wh. One caveat worth flagging: the inverter is not UL listed, which matters if you plan to connect it to home wiring — check with an electrician first. PV and AC charging cables are also not included. Ships in multiple packages — wait for all before assembling.
