Anker SOLIX F3800

The Anker SOLIX F3800 is a 3.84kWh-class LiFePO4 power station with up to about 6,000W AC output and native 120V/240V capability—aimed at home backup, RVs, emergencies, outages, and serious outdoor use. Anker cites scaling from the base pack to about 26.9kWh by adding up to six expansion batteries, and an extreme “dual F3800 + twelve packs” story for very long whole-home runtimes in marketing scenarios. Two F3800 units can be combined for up to about 12,000W max AC output where supported by Anker’s ecosystem. EV charging is supported directly via the unit’s NEMA 14-50 story (marketing cites up to about 6,000W EV charge power with your EV cable—follow Anker grounding and installation guidance). RV integration highlights NEMA 14-50 and L14-30 paths for common inlet setups so you can run multiple RV appliances at once. InfiniPower + EV-class LFP positioning targets a 5-year warranty with a roughly 10-year lifespan story under everyday-use marketing assumptions, plus smart thermal management and impact-resistant design. Wi-Fi/Bluetooth app control supports monitoring and savings-oriented settings. At about 132.3 lb it is a cart-style whole-home class unit, not a backpack carry. In the box: F3800, AC charging cable, solar-to-XT60 charging cable, MC4 solar charging connector, and user manual (solar panels sold separately unless your Amazon style bundles them). Weight: about 132.3 lbs.
