CorePlus: 27,000mAh Pocket-Size Power Bank with 110V/220V AC

Power banks with AC outlets have existed for years, but they're usually mini power-station bricks weighing a kilogram or two — nobody wants one in a carry-on. CorePlus compresses the same capability into pocket size. It offers a 200W 110V/220V AC socket, triple 140W USB-C ports, a 100W DC output and 20W wireless charging (including 7W for Apple Watch), with 27,000mAh capacity (a 22,000mAh version exists). The maker claims two MacBook Pro charges or six iPhone charges per pack. The standout is swappable batteries: hot-swap modules instead of carrying multiple bricks, all within airplane-safe capacity. Launched in November 2025, it drew 2,680 backers and $480,715, about 16,024% funded.
