Anker SOLIX F3800 Portable Power Station - 6000W Dual-Voltage Backup

In this review of the Anker SOLIX F3800 Portable Power Station the bottom line is simple: this is a heavy-duty home and RV backup for users who need long runtimes and the ability to run large appliances. The F3800's standout selling point is its combination of a substantial 3,840Wh LiFePO4 battery and an ultra-high 6,000W AC output with both 120V and 240V support, which means it can handle everything from kitchen appliances to EV charging without constant juggling of loads.

Key Features

• 3,840Wh capacity: Provides a full day of power for a typical family's essentials and can be expanded with up to six additional battery packs for much longer runtime.
• 6,000W dual-voltage AC output: Supports 120V and 240V appliances so large loads like dryers and ranges are possible when needed.
• EV and RV ready: A built-in NEMA 14-50 port and L14-30 compatibility let you directly charge an EV or plug into an RV power inlet without extra grounding accessories.
• Fast solar and AC recharge: Multiple MPPT inputs and up to 2,400W solar input combined with 1,800W AC charging give flexible, relatively quick recharging options.
• Durable LiFePO4 chemistry: EV-class cells and Anker InfiniPower tech promise a long 10-year lifespan and a 5-year warranty for dependable use.
• Smart remote control: Wi-Fi and Bluetooth connectivity with the Anker app let you monitor and control charging and output remotely for efficiency.

Who It's For

The SOLIX F3800 is best for homeowners, RV owners, and small-business users who need a robust, expandable power source that can run large appliances and even charge an EV. Its dual-voltage and high AC output make it suitable for anyone who wants a single unit capable of replacing a small generator or acting as a UPS for critical systems.

It is less appropriate for ultralight campers or users who only need a small emergency battery, since the unit and optional battery packs are aimed at serious backup and prolonged off-grid use rather than minimal, low-power trips.
