In the past year, I invested in a 150W battery-free power system, and I'm thrilled to report that it has proven to be exceptionally dependable. Despite the manufacturer's recommendation for indoor use, I've taken the system outdoors under shelter, and it has consistently delivered exceptional performance. Day in and day out, I've harnessed its power to charge an array 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 exceeded my expectations in terms of performance. With this incredible experience, I'm definitely keeping an eye on getting another unit in the future.
