Not sure of the wattage of this particular Vevor wind turbine, but it's been setup in my back yard for about a year. It will work with any 12V battery, which it will need to store power. I built and wired the box, which houses the battery, fuse block, charge controller and bus board for adding components. Without a battery, it will charge a phone or USB device provided there is wind. On the exterior is a weatherproof panel for USB out, 12V RV "cigarette lighter" plug that can be used to draw power from the system or charge the batter from a wall outlet. When switched on, the panel reads current voltage output. It will charge and output power simultaneously. I've used it a bunch to charge phones, batteries and speakers. It would be good for off-grid use or just to experiment with. You can add solar panels for increased charging. The box lid has a layer of epoxy resin to keep the rain from damaging the plywood. Selling the entire setup; turbine, box and mast. Stands about 18' tall.
