Detailed overview: INIU P63 100W Power Bank
The INIU P63 power bank stands out as one of the most compact power banks on the market able to deliver a genuine 100W over USB-C. With a 25000mAh capacity, it fast charges a laptop, a phone and a tablet at once, without ever weighing more than 391g thanks to INIU's TinyCell technology, which shrinks the high-density cells by 20 to 30% compared with a conventional power bank.
Its main USB-C port works both ways: it delivers up to 100W to charge a MacBook Pro, a Dell XPS or a Steam Deck console at full speed, and accepts up to 65W of input to recharge the bank itself in about 1.5 hours with a suitable charger. Two more ports, a 45W USB-C and an 18W USB-A, can power two extra devices at the same time, with smart power sharing across the three outputs.
The shell fits in the palm of a hand (10.9 x 6.9 x 3.6cm) despite the capacity on board, and a digital display keeps the remaining percentage in view at all times. The short, detachable USB-C cable included doubles as a wrist strap: it clips onto the side of the unit so it never gets lost, and detaches to plug straight into the device being charged. With 25000mAh (about 91Wh), the P63 stays under the 100Wh threshold most airlines allow in carry-on luggage.
Typical uses range from remote work on the road to extended gaming sessions on a Steam Deck, ROG Ally or Nintendo Switch, through photo and video work, where it can recharge a camera battery or a drone several times over. Its main limitation is the weight, noticeable in a pocket but expected given the energy on board, and the deliberately short built-in cable, designed for durability rather than reach. INIU backs the product with a 3-year warranty, unusually generous for such a powerful bank at this price point.

Comparison
How does the INIU P63 power bank compare with other 100W power banks able to charge a laptop, against rivals such as the Ugreen Nexode 100W, the Anker 737 (PowerCore 24K) or the Baseus Blade 100W?

At a similar capacity, the INIU P63 stands out for being noticeably lighter than the Anker 737 and the Baseus Blade, while packing more mAh than the Ugreen Nexode 100W. The Anker keeps the edge on combined power if you charge two devices at once, and the Ugreen stays cheaper at a reduced capacity, but the P63 offers the best balance of capacity, weight and price for anyone who wants a single battery able to keep up with a laptop.

Our tester's review: Guillaume Hoarau
What stands out when you take the INIU P63 out of the box is how much power it packs into such a small shell: 25000mAh and 100W in a unit that fits in one hand. In practice, it delivers: a 14-inch MacBook Pro climbs back to roughly 70% in about 30 minutes with the right charger, and both a Steam Deck and a ROG Ally get several extra hours of play. The short USB-C cable that doubles as a wrist strap is a clever touch, handy so it never gets lost at the bottom of a bag, even if it stays too short for comfortable everyday use. The digital display shows the remaining percentage at a glance, and a full recharge in about 1.5 hours with a 65W charger is a real comfort while travelling. The one real downside, and an expected one given the capacity on board, is the weight in a pocket, better carried in a bag. For anyone who needs a single battery that can keep up with a laptop, it remains a safe bet.
