Iron Stop Solar Powered Spinner Motor SOLAR POWERED: No batteries required. Spins approximately 50rpm when direct sunlight hits the panel. Will NOT charge up, store energy, or work at night but spins instantly when sun shines on the panel. LOTS OF USES: Have something that needs to rotate, turn, twist, twirl, hang, & display? Look no further. Bring life to your 3D wind spinners, crystal twisters, and retail products. Showcase flags, windsocks, chimes, and so much more. SMALL, STRONG, AND DURABLE- Ideal for lightweight items but will hold 6 pounds easy. Avoid tugging or hanging items that are heavy but I often display 3-4 large 3D wind spinners on one motor. They run all day and never get hot. They don't make much noise and are not very big. INDOOR/ OUTDOOR: The solar motor is great to use inside or outside. Inside it must be near a window that gets enough direct sunlight shining in. Easy to use on/ off switch and adjustable panel for convenience. No extra items required but often a 15" extender hook or swivel hook will help get more sun visibility. TIPS: Turn them off when not in use and avoid bad weather as much as possible. Improve the longevity by adding a string or shipityourway smooth spinning swivel clip. The string or swivel will protect the motor from resistance. By adding a swivel your item might also spin a little in the wind.
