Capacity and Airline Compliance
This 20000mAh power bank delivers 74Wh of energy storage, keeping it within the common 100Wh carry-on limit for air travel. The lithium-ion cell chemistry supports fast charging for USB-C laptops such as MacBook models and smartphones including iPhone 16 and 17 series. It is built for remote work, daily commutes and family trips where wall outlets are scarce.
Sustained Output Behaviour
A single port can provide up to 100W when used alone, but connecting multiple devices drops the total output to 15W. The manufacturer notes this level suits overnight or emergency charging rather than simultaneous fast charging. Smart power management also reduces wattage when the attached device is nearly full, in use while charging, or when ambient temperatures are extreme.
Thermals and Travel Safety
Some warmth during high-power charging is described as normal by the supplier. The unit carries UL and FCC certifications and includes advanced safety protections. At 458 grams and measuring 4.8 by 1.9 by 2.0 inches, it fits easily in a carry-on bag. The built-in retractable USB-C cable extends to 27.6 inches and is rated for 35000 retractions and 3000 plug cycles.

Questions about this item
How hot does the FC-22 get when it delivers 100 W through the retractable cable for hours?
Some warmth during high-power charging is normal and managed by smart safety circuits; sustained single-port 100 W output stays within UL and FCC certified limits.
Which cables or adapters must I already own to charge a MacBook at 100 W with this power bank?
None — the built-in 27.6-inch retractable USB-C cable is lab-certified for 35,000+ retractions and plugs directly into a USB-C laptop port for full 100 W output.
Will the FC-22 fast-charge an older phone that only accepts 5 V 2 A on USB-A?
Yes — each USB-A port supplies up to 22.5 W and negotiates down to 5 V 2 A, so legacy devices charge at their maximum supported speed.
