I like it whenever there's a new entrant in the charging category. Cuktech is quickly establishing itself as a brand to watch thanks to its GaN chargers and power banks, and having used the 15 Ultra for the better part of 2025, it's become clear that the brand has a lot of potential.

Like UGREEN's power banks, the 15 Ultra has a vertical design that makes it easier to carry around, and it has a 20,000mAh battery, a built-in panel that shows real-time charging details, and three ports — two USB-C and a USB-A port. It works on the USB PD 3.1 protocol and goes up to 140W, allowing it to charge your MacBook with ease. The best part is that it's now down to $67, undercutting its immediate rivals.
