Advertised capacity The capacity stated by the manufacturer at its battery voltage basis. Do not treat this as delivered USB capacity or a number of complete phone charges.	25000 mAh Source · 2026-10-21 INIU: Cougar Laptop Power Bank 25000mAh 140W (P64-E1) US store pageChecked 2026-10-21.

Documented stored energy A source-stated watt-hour rating for the exact model. Unknown remains unknown; this value does not establish an airline or carrier approval.	92.5 WhFrom the brand comparison chart on the Amazon US listing sold by INIU Innovations Inc.; the INIU US store page states no watt-hour figure.

Maximum single USB-C output The advertised maximum through one supported USB-C output. The device and cable must support the required profile; it is not sustained power for every workload.	140 W Source · 2026-10-21 INIU: Cougar Laptop Power Bank 25000mAh 140W (P64-E1) US store pageChecked 2026-10-21.

Maximum documented recharge input The documented input maximum with the qualifications below. Some peaks require two input ports or a particular battery level. Read the entire input workflow.	80 W Source · 2026-10-21 INIU: Cougar Laptop Power Bank 25000mAh 140W (P64-E1) US store pageChecked 2026-10-21. We reviewed the official page text on the check date.

USB connection arrangement The supplied output connectors, including built-in cables where stated. A built-in cable is not a free socket; count the devices and connector types that you need.	Two USB-C sockets and one USB-A socket; USB-C1 is the listed input. Source · 2026-10-21 INIU: Cougar Laptop Power Bank 25000mAh 140W (P64-E1) US store pageChecked 2026-10-21.

Simultaneous-output conditions Manufacturer sharing limits and unresolved allocation details. Do not add individual port maxima or assume equal distribution between connected devices.	Specification table: USB-C1 + USB-C2 145 W maximum (charted as 100 W + 45 W), USB-C1 + USB-A 118 W (100 W + 18 W), USB-C2 + USB-A 24 W, all three 124 W (100 W + 24 W). USB-C2 alone is 45 W and USB-A 18 W. A comparison chart on the same page says 203 W total.The 203 W chart figure conflicts with the specification table and is not resolved.

Recharge workflow The input connection and conditions behind the advertised maximum. A compatible high-power wall charger may be separate. Peak input is not a guaranteed complete-recharge time.	Recharge through USB-C1 at up to 80 W, with listed input profiles from 5V 3A to 28V 2.85A. A charger able to supply that profile is not in the box list. Pass-through charging is listed; no recharge time is specified. Source · 2026-10-21 INIU: Cougar Laptop Power Bank 25000mAh 140W (P64-E1) US store pageChecked 2026-10-21.

Unit weight The source-reported weight of the pack. Check whether cables or accessories are included in the measurement.	Sources disagree The sources give different answers, so we have not chosen one as fact. Read the attached notes and confirm the current specification before relying on it. The store specification table gives 496 g and the Amazon brand chart 17.5 oz, while the store comparison chart gives 20.8 oz / 589.67 g. Neither figure is chosen.

Cables and package limits Documented supplied cables and unresolved packing-list details. Do not inherit charging bases or cable bundles from another seller selection.	The US box list names one 240 W 2 ft (60 cm) USB-C to USB-C cable and a user manual; no built-in cable is documented. A travel pouch appears in another official list but not in the box list and is not assumed.Amazon item details say 'Built in Cables', which conflicts with the separate cable named in the same listing's What You Get bullet.

Important qualifications The evidence boundaries that affect this comparison. Check the exact model and current support or recall instructions before relying on the package.	Every variant on INIU's US store showed as unavailable when read; the selected route is the Amazon US listing sold by INIU Innovations Inc. 'Airline-approved' is seller wording, not carrier permission, measured delivered energy or safety certification.

Questions to check before buying	INIU's US store page gives no watt-hour rating; 92.5 Wh comes from the brand chart on the Amazon US listing. The same INIU page gives 145 W, 124 W and 203 W total-output figures and 496 g and 589.67 g weights; these conflicts are retained. Every INIU-store variant was unavailable when read, so the Amazon US offer sold by INIU Innovations Inc. is the selected route.
