If you work from a laptop, shoot with a mirrorless camera, use a drone, or play games on a Steam Deck, especially when outdoors, you know that the battery is usually the weakest link. Wall charging points are not always available. Existing high capacity power banks are basically made of bricks. And most compact options don’t have the ability to run a laptop at full speed. So you have to choose between portability and performance.
With the INIU Cougar P63, you no longer have to compromise. One of the best-selling portable charging brands on Amazon, INIU has taken its patented miniaturization technology and brought it to the 25,000mAh, 100W power bank, ideal for professionals, creators, and mobile gamers looking for performance without the hassle. Here’s what you need to know.
Large capacity, without bulk

There has always been a bulk problem with high capacity power banks. Most 25,000mAh units are large and heavy, not ideal if you’re looking for portable charging options on the go, or don’t want to carry around something that big. INIU takes a different approach with the Cougar P63.
Utilizing its proprietary high-density TinyCell and HyperStack architecture, the P63 is 30% smaller than comparable 25,000mAh competitors. It weighs 392 grams, which is not “featherlight”, but no high-capacity power bank either. It’s certainly far more manageable than any of the alternatives, though, with a form factor that’s compact enough to slip into any side pocket of a laptop bag or backpack.
The detachable lanyard cable is also a simple addition that makes a big difference. It has a built-in USB-C cable that also serves as a carrying handle. So not only do you have a nice portable add-on, but you also don’t have to worry about carrying an extra charging cable, something that can be easy to forget and takes up quite a bit of space as well.
25,000mAh capacity, 100W output

The INIU P63 has a USB-C PD 3.0 port with 100W output, which means it can charge the MacBook Pro and other laptops at full wall-charging speeds. There is also a second USB-C port that can handle smartphones and other accessories. This setup won’t fit on a wall charger and is really impressive on a portable power bank.
The 25,000mAh capacity means you’re not only charging at the fastest speed, but you also have enough power. You can use the laptop for up to 17 hours. And with 100W charging, the P63 can handle any laptop that features USB-C charging, including the MacBook Pro and recent Windows laptops.
You can fully recharge the drone or DSLR camera multiple times, the power bank provides the equivalent of 7 additional batteries. It’s also compatible with professional rigs, so you can power your camera while in use. And finally, you can not only fully charge handheld gaming devices like the Steam Deck, ROG Alley, or Nintendo Switch, but also continue playing while doing so.
The P63 is also airline-approved, which is great because higher capacity power banks sometimes fall into a gray area with carry-on rules. This makes it a perfect travel companion that will help you reduce the number of chargers and cables you carry with you while traveling.
The INIU P63 is built to last
The P63 is built to take a hit. It’s survival-tested against 1.2-meter drops, extreme cold, and anything else you might encounter while hiking, camping trips, or shooting on location. The detachable carry cable is also rated for over 10,000 turns.
It comes with several safety features, including a multi-layer thermal system that maintains a stable surface temperature during continuous output. And a real-time LED status display gives you all the necessary information on charging, heat and capacity.
The recharge time in itself is another strong point for the power bank, taking only 84 minutes to go from empty to full. Considering other 25,000mAh power banks that can take 3-4 hours to charge, this is a pretty quick turnaround.
