Product Review

Product Reviewed

Baseus EnerFill / Interfill FC41 power bank (20,000mAh, claimed 100W, with two built-in cables). Bench-tested for real output, charging behavior, thermals, and efficiency.

Key Features Mentioned

Integrated Cables (Built-in)

  • Two integrated USB-C cables built into the body:
    • C1 and C2
  • Also includes separate ports on the side:
    • USB-C + USB-A (with Baseus-style yellow accents)

Display + Capacity / Airline Legality

  • Digital display shows exact battery percentage.
  • Labeled 73 watt-hours, described as carry-on legal (no TSA issues).

Port Power Capabilities (Protocols + Max Wattage)

  • Integrated C1 cable

    • Claimed/officially up to 44W via UFCS + standard quick charge.
    • Test surprise: during testing, it was found to actually support up to 100W USB Power Delivery (PD) (Power-Z tester reportedly missed it).

  • Integrated C2 cable

    • Supports up to 60W PD and multiple protocols.
    • Positioned as best for laptop charging.

  • External USB-C port (where 100W lives)

    • PD 3.0, 20V/5A
    • PPS support
    • Mentions QC5 compatibility
    • Compatible with devices like MacBook Pro, Dell XPS, Steam Deck

  • USB-A port

    • Quick Charge 3.0
    • FCP / SCP / AFC (Samsung/Huawei)
    • Apple 2.4A standard

Charging Performance & Safety Quality

  • Reviewer says power delivery is clean and stable across ports.
  • Multi-stage charging profile observed:
    • aggressive early charging,
    • multiple voltage stages,
    • long constant-voltage tail.

Bench Results (Numerical)

Discharge: Bank → (discharge)

  • 5V basic mode: ran until empty in 3h 54m
  • 62.1 Wh delivered, with voltage holding about ~5.27V throughout (no sag)

Charging: Wall → (charging the power bank)

  • Full charge time: 2h 30m
  • Accepted energy: 75.1 Wh
  • Charging behavior described as normal textbook multi-stage
  • Thermals while charging: cool
    • hotspot peak 32.8°C / 91°F

100W Discharge (max load) via External USB-C

  • First 6 minutes: about ~99W stable
  • Then thermal protection stepped down:
    • to 65W
    • later to 30W
  • Total session: 1h 45m
  • Energy delivered: 63.2 Wh
  • Thermals at peak discharge: hotspot up to 43.7°C / 110.7°F
    • warm but not concerning; heat concentrated near the port/circuit side

Efficiency

  • 83–85% across test modes

Consistency Across Loads

  • Discharge energy was nearly identical regardless of power level:
    • ~62 Wh vs ~63 Wh
  • Suggests stable converter performance across the range.

User Experience Notes (Design + Usability)

  • Build/feel: matte black soft-touch; feels substantial, doesn’t creak, but does collect fingerprints
  • Display: shows battery percentage clearly
  • Thermal experience: charging is “nightstand safe” (cool)
  • Big functional limitation: no true pass-through charging
    • If you plug the bank into the wall and connect a device, output drops to a 5V trickle
    • So you can’t charge the bank and power a laptop/gear at full output simultaneously
    • Not suitable as an overnight “hub”

Pros (As Stated)

  • Real-world performance closely matches marketing (especially short bursts)
  • Fast charging/discharging for a 20,000mAh class bank with measured real wattages
  • Excellent efficiency (83–85%) for the price point
  • Clean, stable power delivery; converter appears consistent across loads
  • Cool charging thermals with reasonable hotspot temps
  • Carry-on legal (73Wh)

Cons (As Stated)

  • No true pass-through charging (limits multi-device/overnight use)
  • Peak 100W doesn’t last—high-output behavior is more of a sprint than sustained performance
  • Thermal design/cooling described as mediocre (passive cooling limited; throttling occurs)
  • Built-in cables are a potential failure point (reviewer expresses real curiosity about long-term durability)

Comparisons Mentioned

  • No specific direct brand/model comparisons were named.
  • Reviewer contrasts value/performance against:
    • cheap power banks (slow, “brick-like,” with ~6-hour charging claims)
    • expensive “pro” units that often still require separate cables and can be inconvenient
  • Claims the bank’s efficiency is competitive with models costing significantly more
  • Notes integrated C1/C2 behavior performs better than expected compared to “official” spec behavior (based on their tester findings)

Verdict / Recommendation

Recommended if you want an honest, compact 20,000mAh power bank with built-in cables and real fast charging—especially short bursts up to ~100W via external USB-C. Not ideal if you need sustained high-watt output or pass-through “use while charging” functionality, since it throttles quickly and lacks true pass-through.

Unique Points by Speaker

  • Single reviewer voice throughout; no separate speakers or distinct viewpoints indicated.
