Baseus EnerFill FC11 — 20,000mAh. Two Built-In Cables. Charge Four Devices. Leave the Cables at Home.

The Baseus EnerFill FC11 is built for people who hate carrying extra cables. Two USB-C cables are permanently integrated into the body — pull one out, plug in your phone, done. The other cable handles a second device simultaneously. Add the two USB-C ports and you have four devices charging at once from a single 20,000mAh bank.

🔌 Dual Built-In USB-C Cables — The Entire Point

Two braided USB-C cables live inside the FC11’s body — integrated, tested for durability, and available the moment you need them. No zip pockets, no cable pouches, no “I left the cable at home” moments. Both cables support fast charging output. Combined with the two USB-C ports, the FC11 can simultaneously serve: a laptop via port, an Android phone via cable 1, an iPhone via cable 2, and earbuds via the secondary port — all fast charging, all at the same time.

⚡ 45W Maximum Output — Serious Speed

The FC11 pushes up to 45W from a single USB-C port — charging an iPhone 16 from 0% to 50% in under 30 minutes. Samsung Galaxy, Google Pixel, iPad Pro — all receive optimal fast charging speeds. The dual-cell design (2 × 10,000mAh premium cells) maintains stable high output without the voltage drops common in single-cell budget competitors.

🔋 20,000mAh Dual-Cell Architecture

Unlike single-cell 20,000mAh banks that underperform at high loads, the FC11 uses two premium 10,000mAh cells working in parallel — providing more stable output voltage, better heat management, and longer cell life. The dual-cell design is the reason the FC11 can sustain 45W output without throttling.

📺 Digital Display + Low-Current Mode

The smart digital display shows exact battery percentage — no LED dot guessing. Low-Current Mode activates automatically for low-power devices like wireless earbuds, smartwatches, and electric toothbrushes, delivering a safe trickle current that won’t damage sensitive batteries. CCC certified and international aviation-compliant.
