Before, if you wanted to charge laptops or gaming handhelds, you usually had to bring their proprietary chargers and hunt for a wall outlet. In this video, I tested something I’ve been wishing for: a portable power bank that can push serious power—up to 150W. I checked out CUKTECH’s compact-but-powerful lineup, the CUKTECH 10 and CUKTECH 15, and broke down what they can realistically deliver, what devices benefit the most, and which one makes more sense for your daily carry. I started with a quick unboxing, then focused on design and portability. Both have a metallic silver build using high-grade, flame-resistant materials, they’re soft to the touch, not fingerprint-prone, and they’re airline-safe. The big differences are size/weight and features: the CUKTECH 10 is lighter (283g) and has a 2-inch color TFT LCD showing battery level plus input/output, while the CUKTECH 15 is heavier (453g) but gives you more ports (2x USB-C + 1x USB-A). On charging, both support fast protocols like USB PD (up to 100W), PD PPS (60W), Samsung SFC 2.0, QC4/4+, and even up to 120W Xiaomi Hyper/Turbo Charge. Just remember: “up to 150W” is combined output (USB-C up to 120W + USB-A around 30–33W).
