Anker SOLIX PS400 Portable Solar Panel

Main Specs (In a Brief)
Output Power: 400W peak output utilizing premium Monocrystalline solar cells (high 23% conversion efficiency).
The Build: A heavy-duty four-panel folding design. Weighs 35.3 lbs (15.9 kg) and features a built-in carrying handle.
Sun Tracking: Features integrated adjustable kickstands that let you lock the panel at 4 different angles (30°, 40°, 50°, or 80°) to catch maximum sunlight depending on the time of day or season.
Durability: Fully IP67 waterproof and dustproof rated, meaning it can safely handle sudden downpours or rugged dirt campsites.
Connectivity: Uses industry-standard MC4 connection points and includes a long 9.8-foot MC4 cable alongside an MC4-to-XT60 adapter.
Who Is It Best For?
Mid-to-Large Power Station Owners: It is natively optimized to rapidly charge larger generators—specifically the Anker Solix C1000, F2000 (767), or F3000—where a small 100W panel would take days to fill the battery.
Off-Grid RVers & Overlanders: Ideal for travelers who park their vehicle in the shade but want to unfold a high-power panel 10 feet out in the sun to cleanly sustain their power station without engine noise.
Disaster Preparedness: Essential for anyone building a gas-free emergency home backup array, allowing you to completely refill a dead 1kWh battery bank in roughly 2 to 3 hours of direct sunlight.
Verdict: Do not buy this for small, pocket-sized phone chargers or the ultra-light C300 DC. This is a large, high-capacity solar array meant to quickly replenish mid-to-large-scale solar generators.
