Most solar power banks I've tested were gimmicks - this one is the real deal

ZDNET's review of the ToughTested ROC16 (16,000 mAh) describes a rugged, IP67-rated power bank with multiple ports (USB-A, QC 3.0, 18W USB-C PD, microUSB), 15W wireless charging, a built-in LED flashlight, and a small solar panel. The reviewer praises its build quality and usefulness for emergency/off-grid situations but emphasizes the solar panel's severe limitations (about 57 hours of sunlight to fully charge), the inefficiency of wireless charging, its bulky weight, and sensitivity to heat; the device is recommended as a dependable emergency power option rather than a practical daily solar charger.
