Over the past year, my investment in a 150W battery-free power system has proven to be incredibly reliable. Despite the manufacturer's recommendation for indoor use, I've taken the system outdoors under a shelter, and it consistently delivers outstanding performance. Day after day, I've used its power to charge a variety of devices – from LED light strips and phones to tablets, Bluetooth earbuds, and even my computer. Connecting it to a USB/110V AC power strip through an inverter has truly surpassed my performance expectations. With this fantastic experience, I'm definitely considering getting another unit in the future.
