High-capacity power banks have always had a bulk problem. Most 25,000mAh units are large enough that you notice them in your bag, and the ones that deliver true laptop-speed charging tend to be worse. The INIU Cougar P63 takes a different approach. Using INIU's proprietary TinyCell and HyperStack architecture, the P63 comes in 30% smaller than comparable 25,000mAh power banks, measuring 4.3 x 2.7 x 1.4 inches and weighing just under 14 ounces. That's meaningfully more portable.
The single 100W USB-C output is what delivers the headline spec. Most laptop chargers top out at 65W, so the P63 can match or exceed wall-charging speed for a MacBook Pro 14", Dell XPS, ThinkPad, and most other USB-C laptops. In 25 minutes, it can bring a MacBook Pro 14" to 42% from empty. For a long travel day or an afternoon of coffee-shop meetings, the 25,000mAh capacity adds up to roughly 17 hours of web browsing – enough to get through a full workday without hunting for an outlet.
Ports for everything, cable included
The P63 ships with a detachable 100W USB-C GoCord cable that doubles as the carry cable, so there's nothing extra to pack. A second USB-C port handles phones, tablets, or accessories at up to 45W, and a USB-A port covers older devices at up to 18W. Running both USB-C ports together delivers up to 110W combined, so you can charge a laptop and a phone at full speed simultaneously.
Recharging the P63 itself takes about 84 minutes via the 65W input, considerably faster than the three to four hours typical of most 25,000mAh power banks. The LED display shows remaining capacity at a glance. For air travel, the P63 clears the FAA's 100Wh limit.
Built for the road
INIU survival-tested the P63 for 1.2-meter drops, extreme cold, and sustained high-power output. The carry cable is rated at more than 10,000 bends. For a power bank that lives in a laptop bag and may be ported along for ski vacations or rain forest treks, those specs provide confidence that the P63 will support you for years to come.
The bottom line
For only $75.99, the INIU Cougar P63 delivers genuine 100W laptop charging in one of the smallest 25,000mAh bodies available. If you regularly charge a laptop away from a wall and want something compact enough to carry wherever your work or play takes you, the P63 makes a strong case as the power bank to buy.
The P63 is available now on Amazon and the INIU website.
