Forget rummaging through your bag for a charging cable that may or may not be frayed. The Baseus EnerFill FC11 packs two USB-C cables directly into its chassis, so the wiring you need is always exactly where you left it — attached.
Capacity sits at 20,000mAh, which is deliberately chosen: it slips under the TSA threshold for carry-on batteries, making it a legitimate travel companion rather than a checked-bag gamble. That’s enough juice to top up a phone several times over, or to keep a laptop breathing through a long haul.
The headline number is 45W fast charging on output, paired with 30W rapid input so the bank itself refills at a respectable clip. It also supports pass-through charging, meaning you can power your gear while the FC11 is plugged into the wall — handy when you’ve only got one free outlet and a pile of dying devices.
Speaking of piles: this is a genuine four-in-one charger. The FC11 offers two built-in USB-C cables, a separate USB-C port, and a USB-A port, letting you feed four devices at once. Phone, earbuds, tablet, smartwatch — all simultaneously, from a single brick.
Those integrated cables are the part that usually makes people nervous, since a built-in cable that snaps turns your power bank into a paperweight. Baseus says it tested them to withstand over 20,000 pulls and bends, which is the kind of abuse only a well-traveled charger accumulates over years of being stuffed in and out of bags.
What holds this design together is the philosophy behind it. Most power banks are dumb reservoirs — you supply the cables, you supply the ports, you supply the patience. The FC11 flips that, treating the cable as part of the product rather than an accessory you’re expected to source yourself. The trade-off is fixed connectors, but for a USB-C world that’s an increasingly safe bet.
The result is a battery that reduces the number of loose parts in your life. For anyone who has ever landed in a new city only to discover the one cable they packed was the wrong one, that’s a meaningful upgrade over raw milliamp-hours.
- Capacity: 20,000mAh (TSA carry-on compliant)
- Output: 45W fast charging
- Input: 30W rapid input, pass-through supported
- Ports: 2 built-in USB-C cables + USB-C port + USB-A port (charges 4 devices at once)
- Durability: cables rated for 20,000+ pulls and bends
It’s a straightforward proposition executed with unusual attention to the annoyances that actually plague travelers. Sometimes the smartest feature isn’t the fastest wattage — it’s simply never having to hunt for a cable again.
