INIU's Cougar P63 Crams 100W and 25,000mAh Into a Brick That Squeaks Under the TSA Limit

Every high-watt power bank launched in 2024 makes the same pitch: enough juice to run a laptop, small enough to forget in a backpack. INIU's Cougar P63 is the latest, and its most interesting number is one the marketing barely mentions. At 25,000mAh and 3.7V nominal, the pack sits at roughly 92.5Wh, comfortably under the 100Wh airline carry-on ceiling. That's the spec frequent flyers actually care about.

The headline figures are competitive without being class-leading. INIU quotes 100W PD 3.0 from a single USB-C port, 110W combined across two ports, and an 84-minute self-recharge. The unit weighs 392.3g (13.8oz), which INIU claims is around 30% smaller than typical 25,000mAh banks. That's plausible, given gallium nitride and denser cell chemistry have been shrinking this category for two years, but Anker's Prime 27,650mAh and UGREEN's Nexode 25,000mAh occupy the same shelf, and INIU doesn't say which competitors it benchmarked.

A few details are genuinely thoughtful. The detachable USB-C cable doubles as a carry handle, which is the kind of small idea most brands miss. The LED display shows real wattage rather than the four-dot battery hieroglyphs that still ship on cheaper packs. INIU also cites a 1.2m drop rating and a 10,000-bend cable, though neither comes with an IP rating or an independent test reference.

What the spec sheet doesn't address: thermal throttling under sustained 100W draw, whether the second port is USB-A or USB-C (the 110W combined figure suggests one of each), and how quickly capacity degrades after a year of fast recharges. INIU's two-year warranty is shorter than Anker's, and the brand still trades primarily on Amazon listings rather than a service network.

Pricing and launch-window details sit on INIU's product page at iniu.com. At anything under $90, it's a reasonable buy. Above that, the established competition gets very interesting.
