This WANROY T500 is my first modern portable solar generator and I am very pleased with its functionality and usefulness. It's not my only source of power in an emergency, but in an extended outage I can keep my home fridge and garage freezer running for at least 5 hours, and longer with available solar power. On a recent RV camping trip, I used the T500 to charge my camera battery for a week and run a laptop, phone, coffee maker, and iPad every day. Before choosing the T500, I read many reviews and compared it to several other generators. It turns out that my choice was not wrong.
